In The Lifelong Evolution of a Safety Case, we look at how to Review and revise a Safety Case and Re-Issue a Safety Case Report.
When it comes to ensuring safety throughout any Product, System, or Service lifecycle, reviewing and revising the Safety Case isn’t just a recommendation—it’s essential. The age or status of equipment isn’t simply about how old it is. Instead, it reflects an understanding of its condition, the effects of changes, and its performance in varying environments over time. Let’s dive into the key principles of maintaining and revising a Safety Case and the potential risks and strategies to avoid them.
Why Review the Safety Case?
Changes in operations, equipment condition, or organizational controls can disrupt the assumptions on which the original Safety Case was built. Recognizing when a review is needed ensures safety remains uncompromised.
Here are examples of scenarios that demand attention:
Structural Modifications: Repairs or upgrades impacting safety.
New Activities: Introduction of new tasks or uses for the equipment.
Environmental Changes: Shifts in operational environments or equipment roles.
Incident Data: Insights from accidents or maintenance inspections.
System Evolution: Decommissioning, extended use, or technological upgrades.
Figure: Relationship between the Safety Management System and Safety Case in terms of Age and Status
Challenging Assumptions: The Foundation of Safety
A Safety Case is never static—it evolves as evidence and conditions change. It’s vital to challenge existing arguments continually. If new evidence undermines the validity of the Safety Case, steps like obtaining further proof, implementing corrective actions, or, in extreme cases, halting operations may be necessary.
Consider this: what was deemed safe at one time might become risky due to wear, updates, or new findings. Regular reviews ensure the Safety Case remains robust and relevant.
Ownership and Administration: Who’s in Charge?
The custodian of the Safety Case is the Project Safety Manager, the linchpin in ensuring safety throughout the lifecycle of the system. This individual must coordinate all safety activities, maintain the Safety Case, and oversee its interaction with the Safety Management System (SMS).
While contractors may handle the technical details, the responsibility for ensuring the integrity and adequacy of the Safety Case rests with the appointed safety delegation holder.
Records Matter: Documenting Safety
Every decision, from hazard mitigation to safety strategy adjustments, must be meticulously recorded. Key documents feeding into this process include:
System Requirements Document: Detailing specific safety needs.
Through-Life Management Plan: Ensuring continuity in safety oversight.
A central part of this process is the Hazard Log, which serves as the repository of all identified risks and their management status. (see Procedure SMP11 – Hazard Log).
Avoiding Pitfalls: The Warnings
The warnings and project risks identified in all the other procedures, from SMP01 to SMP11 can manifest themselves through effects on the Safety Case, as it brings their outputs together. Also, there are other project risks specific to the Safety Case.
Neglecting regular reviews or documentation can lead to significant issues, including:
Delays in Safety Approvals: Failure to engage approval authorities early can result in unmet safety requirements and service delays.
Outdated Safety Cases: A mismatch between documentation and the system’s current state undermines credibility.
Inadequate Risk Analysis: Improper techniques during safety assessments may yield an incomplete Safety Case.
Lost Records: Poor documentation management can erode trust in the safety process.
Completing the Circle: The Role of Collaboration
Maintaining a credible and effective Safety Case is a collective effort. Contractors, safety committees, and stakeholders must work in concert to identify and mitigate hazards. Sharing data, especially during transitions between contractors, is crucial to avoiding gaps in safety oversight.
Wrapping Up
The Safety Case is more than a set of documents—it’s a dynamic framework ensuring that safety risks are continuously managed throughout the lifecycle of a system. With proper reviews, updates, and collaboration, it provides confidence that safety remains a top priority, no matter the changes a system undergoes.

Comprehensive Project Safety Management Plans. Safety is a critical element in any large-scale project, especially in the context of defense and complex systems. One essential tool for managing safety is a Safety Management Plan (SMP). In this article, we’ll break down the process and structure of an effective SMP, highlighting its objectives, content, and how to ensure its successful implementation.
In other words, an SMP serves as a structured approach to managing safety across a project’s lifecycle, ensuring that all risks are identified, analyzed, and mitigated effectively.
Objectives
The core objectives of a Project Safety Management Plan are twofold:
Ensuring Safety Performance: The plan guarantees that the system remains safe throughout its entire lifecycle.
Maintaining Assurance: It provides the necessary information to demonstrate that safety objectives are being met continuously.
Achieving these goals requires a coordinated, structured approach that integrates risk management and establishes clear safety requirements right from the start.
SMP in Practice: Contractor vs. Enterprise Project
Each organization involved in the project—whether it’s the Enterprise Project or a contractor—must produce a distinct SMP that outlines their safety activities. Though separate, these plans should align with each other and the overall project goals. This integration is crucial as safety activities span system development, trials, and any necessary safety approvals.
The SMP discussed here focuses specifically on the Enterprise Project’s plan, which acts as the guiding document for all safety management activities.
Procedure and Methodology
Establishing the Safety Management Framework
The SMP outlines the strategy for ensuring safety and documents the Safety Management System for a particular project. It’s more than just a checklist—it’s a comprehensive program that captures safety timescales, milestones, and other relevant data.
Key areas to be addressed in an SMP include:
General Equipment Safety: An overarching review of the equipment’s safety features.
System-Specific Requirements: For example, airworthiness or ship-specific hazards.
Occupational Safety: Encompassing manual handling, packaging, transport, and more.
Operational Safety: Ensuring safe procedures during the use phase.
Maintenance Safety: Guidelines for repair and maintenance activities.
Training and Disposal: Safety considerations for personnel training and end-of-life disposal of the system.
Creating a Tailored Safety Strategy
No two projects are identical, and neither should their SMPs be. Each plan must be custom-designed to fit the specific project requirements, ensuring a safety strategy that is practical and achievable.
Structuring the SMP: Essential Elements
An effective SMP should contain the following sections:
Outline Description: Clearly defines the equipment, its purpose, operational environment, and expected capabilities.
Safety Management System: Details the system’s objectives, managerial tasks, and responsible organizations.
Responsibilities and Resources: Identifies key personnel and defines their roles through a RACI chart (Responsible, Accountable, Consulted, Informed).
Audit Arrangements: Outlines internal and independent audit processes.
Requirements and Acceptance Criteria: Defines safety requirements, targets, and the standards by which success will be measured.
Safety Case Scope and Strategy: Lays out the assessment strategy and techniques to control hazards.
Safety Programme: A comprehensive work plan linked to the Through Life Management Plan.
An example template for structuring your SMP can be found in Annex A. Refer to Annex B for a sample RACI chart to guide accountability and communication.
Warnings and Potential Project Risks
The SMP is the linchpin of project safety management. If not accurately maintained, the project may face unforeseen delays, increased costs, or compromised safety performance.
Common Pitfalls:
Inadequate Detail: Missing out on key safety activities can lead to delays and escalated costs.
Outdated Information: Failing to keep the SMP updated can result in misalignment with the actual safety activities.
Insufficient Review: Lack of endorsement by the Project Safety Committee (PSC) may mean the plan does not accurately reflect stakeholder responsibilities.
These risks underscore the importance of a thorough, continuously updated SMP.
Procedure Completion and Review
The Project Safety Committee (PSC) is responsible for drafting, endorsing, and reviewing the SMP, ensuring that safety requirements and acceptance criteria are clearly defined and agreed upon by all parties.
Timing:
Initial Production: Start as early as the Concept stage.
Ongoing Updates: Review and update the SMP regularly, especially during key project milestones.
The SMP should be a living document that evolves as new information arises or project requirements change.
Safety Planning: Required Inputs
This procedure for Safety Planning requires inputs from:
These inputs should be integrated with other management plans throughout the acquisition cycle.
Outputs:
The SMP’s outputs should feed into several project documents, including:
System Requirements Document: Capture specific safety needs.
Customer Supplier Agreement: Document mutual agreements on safety deliverables.
Through Life Management Plan: Align with long-term safety management.
Business Case Submissions: Support safety-related elements in decision-making processes.
All meeting minutes should reflect decisions made regarding the SMP’s development and up-issue.
Conclusion
The Safety Management Plan is the cornerstone of safety assurance in complex projects. Properly implemented, it serves as a robust framework to manage safety risks, ensure compliance, and maintain confidence in the system’s safety performance throughout its lifecycle.
By following the structure and content outlined in this guide, project teams can create a comprehensive, effective SMP that aligns with the highest standards of safety management.d up-issue.

Our Second Safety Management Procedure is the Project Safety Committee. Okay, so committees are not the sexiest subject, but we need to get stakeholders together to make things happen!
Project Safety Committee: Introduction
In safety-critical industries such as defense, aerospace, and engineering, maintaining a robust safety management system (SMS) is paramount. A Project Safety Committee (PSC) plays a vital role in overseeing, coordinating, and ensuring safety compliance throughout the lifecycle of equipment and systems. This guide will explore the role, objectives, and procedures of a PSC, as defined in UK Def Stan 00-56, and provide insights on how to structure and run a PSC effectively.
What is a Project Safety Committee (PSC)?
A Safety Committee is defined as:
Simply put, the PSC is a formal body composed of experts and decision-makers from various disciplines, convened to ensure that safety-related decisions are well-founded, thoroughly vetted, and correctly implemented.
Objectives of a PSC
The key objectives of a PSC are to ensure effective coordination, agreement, and proper response from those with safety responsibilities. Specifically, the PSC achieves the following:
Coordination of Safety Issues: The PSC acts as a platform where all stakeholders responsible for safety management can ensure coordination on safety issues, eliminating silos.
Access to Knowledge: It provides decision-makers with access to relevant knowledge and expertise across different domains, including engineering, maintenance, user experience, and risk management.
Oversight of the Safety Case: The PSC ensures competent oversight of the safety case throughout its development and maintenance.
Audit Trail: keep detailed meeting records, and establish an audit trail showing that advice was sought and safety decisions were grounded in expertise.
The PSC should facilitate smaller working groups or sub-committees to address specific safety issues when necessary, ensuring that no aspect of the safety management process is overlooked.
Project Safety Committee: Procedure
Membership of the PSC
The effectiveness of a PSC largely depends on its membership, which should include representatives with specific roles and expertise, as appropriate to the project. Typical members might include:
Delivery Team Representatives (e.g., Project Safety Manager)
Logistics Support Teams
Equipment Support Teams
Customer and User Representatives
Prime Contractors and Subcontractors
Design Organization
Independent Safety Auditor
Specialist Advisors
Regulator / Safety Authority
Safety and Environmental Protection Group
Moreover, it may also include contractors, consultants, and subject matter experts from other government departments or foreign defense bodies.
More information on PSC membership has been provided in Annex A – example Terms of Reference for a PSC.
Chair and Quorum
A critical element of any PSC is competent leadership. The PSC Chair must be a safety-competent individual holding formally-delegated authority for the program’s safety tasks, typically defined in a Letter of Delegation. This document outlines the chairperson’s responsibilities and authority.
For a PSC to conduct its business, it must be quorate, meaning a minimum number of key members must be present. This quorum usually consists of:
Delivery Team safety delegation holder
Project Safety Manager
Design organization representative
Customer representative
Safety Case author
If a quorum is not achieved, the meeting can still proceed, but decisions will only be implemented after receiving approval from the absent quorum members..
Quorum
In order for a PSC to make decisions concerning the safety of a capability or equipment, it should be declared quorate at the beginning of the meeting. In order for a PSC to be declared quorate, the following SQEP and authorized members should be in attendance:
Delivery Team safety delegation holder
Project Safety Manager
Design organization
Customer representative (Project Sponsor)
Safety Case author
The quorate for a PSC can be expanded depending on the nature of the project. Details should be provided in the Project Safety Management Plan (SMP) or Terms of Reference.
If a quorum is not achieved, the meeting can still proceed, but decisions will only be implemented after receiving approval from the absent quorum members.
Meeting Frequency and Structure
PSC meetings should be scheduled regularly, though the frequency will depend on the project’s complexity and phase. Typically, meetings occur more frequently during the early design and review stages, and less frequently once the system is in service.
For smaller projects, PSC activities can be integrated into broader project meetings, ensuring safety remains a specific agenda item. Larger or more complex projects may require dedicated PSC meetings with support from Working Groups to assess hazards or system integrity.
Working Level Support
Depending on the complexity of the project, one or more working groups may be established that support the PSC by assessing hazards or reviewing the integrity of specific systems. Integrity working groups could consider structure, propulsion or other electrical or mechanical systems, reporting significant issues to the PSC.
Role of the Safety Management Committee (SMC)
For large-scale projects or portfolios, a Safety Management Committee (SMC) may be established to manage multiple PSCs across similar systems. This ensures consistency in safety management policy and strategy across projects. The SMC will oversee the activities of individual PSCs, ensuring adherence to safety management plans (SMPs).
Figure 2.1 shows an example of a Safety Committee structure, together with the management documents that sit at the relevant committee level.
Figure 2.1 – Safety Committee Structure
Figure 2.1 represents an example of a Safety Committee structure, with supporting working groups and hazard reviews in place. Teams can modify the structure of the Safety Committees to suit the specific organization of the program. The emphasis should be on establishing a Safety Committee with suitable chairmanship and Terms of Reference.
Project Safety Committee Authority and Competence
The chairman of the PSC should hold a Letter of Delegation detailing the authority for carrying out the safety management tasks on that program.
The PSC exists to provide information and specialist advice to those who have specific responsibility for safety management on an acquisition project so that they can reach informed decisions. The Project safety delegation holder should seek and consider relevant advice through the PSC but remain the decision-maker.
While not all members of the PSC need to have specific competence and experience in Safety Management, some committee members must have this competence and are consulted. In addition to the safety delegation holder, whose competence must be established before their delegation being issued, other members of the PSC who must be safety competent would typically include the Project Safety Manager and the Independent Safety Auditor (if appointed).
As a minimum, the Project Safety Manager should have system safety competence at the practitioner level. Competence requirements for the safety delegation holder will be defined in a relevant Assignment Specification.
Where beneficial, combine committees for safety and environmental management activities. Align programs as far as possible and share data where relevant.
Where there are separate safety and environmental committees, these could meet consecutively over the morning and afternoon. Members and specialists should attend as appropriate to each.
The PSC covers groups of similar projects within a Delivery Team where common activities are required. Separate committees are better for very large, high risk or diverse projects within a Delivery Team.
The PSC meets regularly as a body, or its work is included as a permanent item in another forum (in this instance care should be taken that all relevant parties are included), or simply through written communications. This last option is less desirable because there is no opportunity for direct interaction.
Record-Keeping and Documentation
Accurate record-keeping is vital to ensure transparency, accountability, and auditability. PSC meeting minutes should document:
Attendees
Key discussions
Advice and recommendations
Decisions made
Agreed actions
These records often feed into larger project documentation, such as the System Requirements Document, Through Life Management Plan, and Safety Management System (SMS).
Review and Agreement of Safety Documents
A key PSC function is reviewing safety documents and advising the safety delegation holder on their suitability. Agreement can be recorded formally via document sign-offs or recommendations in PSC minutes. This process ensures that all safety documentation, including the Safety Case, meets the required standards before formal approval and implementation.
Risks and Pitfalls
Failure to establish or effectively run a PSC can lead to significant risks for a project, including:
Incomplete stakeholder engagement, leading to safety requirements not being adequately defined.
Inappropriate safety activities, if the PSC does not review and approve the SMP.
Infrequent meetings, potentially delaying issue identification, risking project time and cost.
Lack of clear authority, causing confusion between Enterprise and contractor responsibilities, which could shift accountability from the designers to the PSC.
By mitigating these risks through clear terms of reference, structured meetings, and well-defined roles, the PSC can ensure project safety management remains robust and reliable.
If the PSC does not meet with sufficient frequency, then they may not identify in a timely manner, any issues with the safety program. This could result in impacts on project time and cost.
If the PSC attempts to control the detailed design solutions, rather than relying on the contractor’s Safety Committee and design function, then Enterprise will take responsibility from the designer. Enterprise staff will be represented on the contractor’s Safety Committee and shall exercise influence at that forum and through setting appropriate requirements.
Project Safety Committee: Timing
Formation
Establish the PSC during the Concept phase of a project by the Customer, or Requirements Manager, through the Capability Working Group, in conjunction with the relevant Project Director, to set out the safety requirements for the equipment.
Meetings
The required frequency of the PSC meetings depends on various factors including the stage of the project, the complexity of the system, and whether the PSC is supported by Working Groups or has complete responsibility. Hold meetings at greater frequency during periods of significant review and decision-making, typically when project milestones are approaching.
PSC meetings may occur less frequently during periods of stability, such as during the in-service phase, when fewer safety decisions are necessary. However, the PSC still has an important duty to provide oversight of the Safety Case and ensure that it remains valid and monitoring safety performance. Consider whether the system or its usage is changing and seeking counter-evidence that shows the predicted level of safety performance is not being achieved in practice.
Project Safety Committee: Required Inputs
The procedure may use the following reference inputs, as available:
Other Safety Audit Plans (e.g. self or Peer audit);
Safety Audit Report;
Hazard Log Report;
Safety Requirements;
Safety Assessment Report;
Safety Case Report.
Acquisition System Guidance Functional Competencies for System Safety Management;
Records of previous meetings of the Safety Committee.
Project Safety Committee: Required Outputs
The outputs of the procedure will comprise:
Established Safety Committee membership;
Defined Terms of Reference for the Safety Committee (see Further Guidance – Examples Terms of Reference for Project Safety Committee);
Records of Safety Committee meetings, including advice given and the actions, agreed;
The advice given by members of the Safety Committee should include recommendations on whether a reviewed document (e.g. Safety Management Plan or Safety Case Report) should be authorized by the Project Director. If authorization is not recommended, then the reasons should be recorded.
Conclusion
The establishment and management of a Project Safety Committee (PSC) are critical to the safe delivery of defense and engineering projects. Through clear objectives, expert membership, and rigorous oversight, the PSC ensures that safety remains at the forefront of project decision-making, thereby protecting both people and assets.
By following this comprehensive guide, organizations can structure their PSCs effectively, aligning with safety standards and regulatory requirements. The PSC is not just a procedural necessity; it is a cornerstone of responsible project management in safety-critical environments.

Introduction
Definitions
A stakeholder is anyone who will be affected by the introduction of the system and who needs to be consulted or informed about the development and fielding of the system, and anyone who contributes to the ultimate acceptance of the project.
Project Safety Initiation: Objectives
This procedure describes the start-up of safety management activities on a project. It identifies safety stakeholders and legislative and other standards that need to be satisfied. The procedure also creates the key elements of the safety management organization for the project.
In normal circumstances, this procedure would be applied at the outset of a project, early in the Concept phase. However, it can be applied at any point of the life cycle where it is necessary to initiate a formal safety management process on an existing system. The procedure may also be re-applied at significant points in the life cycle (e.g. after Full Business Case approval), to review and update the project safety arrangements and ensure that they continue to be appropriate.
Comprehensive Guide to Safety Management Procedure Initiation
Safety management is critical to any project, especially those involving complex systems with safety and environmental implications. This procedure outlines the early-stage safety processes that should be followed, assuming that the Program Director has already been appointed and safety responsibilities have been delegated to a competent team member within the delivery team. The goal of safety initiation is to ensure that safety management starts on a firm basis, identifying crucial stakeholders, regulatory authorities, and internal teams responsible for safety and environmental protection.
In this article, we will provide an in-depth understanding of the safety initiation process, stakeholder identification, project safety organization creation, compliance considerations, and necessary documentation.
Purpose of Safety Initiation
The primary objective of safety initiation is to commence the safety management process by:
Identifying stakeholders, regulators, and approval authorities.
Appointing a Project Safety Manager (PSM) and, if required, an Independent Safety Auditor (ISA).
Forming the Project Safety Committee (PSC).
Ensuring compliance with safety and environmental regulations and creating a responsible, accountable, consulted, informed (RACI) chart.
This procedure helps mitigate risks to project timelines, cost, and overall safety by ensuring safety requirements are identified and met early in the project lifecycle.
Project Safety Initiation: How It’s Done
1. Stakeholder Identification in Safety Initiation
The identification of stakeholders is crucial. Stakeholders include any individuals or groups impacted by the project’s development or operation, as well as those responsible for the project’s approval and compliance. This may include industry professionals, regulatory bodies, and environmental authorities. Here’s how to systematically identify and involve relevant stakeholders:
Who Are the Stakeholders?
A stakeholder is defined as anyone affected by the system or involved in its acceptance, including:
Individuals who are responsible for safety at any stage of the project.
Groups or individuals with safety information or requirements relevant to the project.
Subject Matter Experts (SMEs) with specialized knowledge critical to project safety.
Consulting Key Stakeholders
At a minimum, the following must be consulted:
Project Sponsor (e.g., Director of the End Users’ Business Unit).
Equipment Users who will be directly affected.
Director Technical responsible for the technical aspects of the project.
Safety & Environmental Protection Group tasked with compliance.
Other Delivery Teams involved with subsystems or associated projects.
After identifying stakeholders, record their involvement and details in Form SMP01/F/02 – Register of Stakeholder Requirements and Information. External stakeholders such as other government departments or industry experts should also be logged into the communication plan. For complex projects, develop a communication plan outlining stakeholder contact details, responsibilities, and relevant security considerations.
2. Ensuring Compliance with Safety Regulations
Compliance with safety and environmental regulations is a critical responsibility of the Delivery Team. The following methods ensure compliance across various safety aspects:
Key Compliance Strategies:
System Specifications: Delivery Teams develop specifications to meet user requirements, ensuring safety and environmental standards are incorporated.
Through Life Management Plan (TLMP): This plan outlines the long-term impact of safety and environmental legislation on equipment.
Enterprise Guidance: Use internal guidelines when creating contracts to include safety and environmental performance targets.
Sources for Regulatory and Legislative Information:
To maintain compliance with safety and environmental legislation, teams can access a wide range of resources, including:
Legislative registers held by the program teams.
Defense Regulator intranet pages.
Health & Safety Executive publications and other professional societies.
Suppliers, contractors, and consultants with expertise in safety and environmental law.
The Delivery Team must identify applicable legislation at the start of the project and continuously update a legislative register as part of the Safety Case.
3. Creating a Project Safety Organization
Establishing a robust safety management structure is essential to ensure compliance with safety standards and regulations. The Safety Management Plan (SMP) will eventually document the project’s entire safety organization, but before that, some key safety roles need to be defined.
Steps to Set Up Project Safety Organization:
Develop a Project Safety RACI Chart: This chart defines who is Responsible, Accountable, Consulted, and Informed at different stages of the safety process.
Appoint a Competent Project Safety Manager (PSM): This individual is responsible for overseeing safety management throughout the project.
Appoint an Independent Safety Auditor (ISA): For complex or high-risk projects, appointing an ISA is advisable. The ISA ensures that safety audits are conducted independently.
Form a Project Safety Committee (PSC): This group will be responsible for monitoring and governing safety issues within the project.
3. Ensuring Compliance with Safety Regulations
Compliance with safety and environmental regulations is a critical responsibility of the Delivery Team. The following methods ensure compliance across various safety aspects:
Key Compliance Strategies:
System Specifications: Delivery Teams develop specifications to meet user requirements, ensuring safety and environmental standards are incorporated.
Through Life Management Plan (TLMP): This plan outlines the long-term impact of safety and environmental legislation on equipment.
Enterprise Guidance: Use internal guidelines when creating contracts to include safety and environmental performance targets.
Sources for Regulatory and Legislative Information:
To maintain compliance with safety and environmental legislation, teams can access a wide range of resources, including:
Legislative registers held by the program teams.
Defense Regulator intranet pages.
Health & Safety Executive publications and other professional societies.
Suppliers, contractors, and consultants with expertise in safety and environmental law.
The Delivery Team must identify applicable legislation at the start of the project and continuously update a legislative register as part of the Safety Case.
4. Safety Documentation and Records
Documenting safety processes ensures accountability and maintains a clear safety management trail. These records feed into critical project documentation, including:
System Specification: Defines specific safety requirements.
Customer-Supplier Agreement: Documents agreements on safety information.
Through Life Management Plan (TLMP): Outlines the ongoing safety and environmental impact.
Safety Elements in Business Case Submissions: Ensures all safety-related information is considered in formal project submissions.
Proper documentation supports future audits, stakeholder engagement, and compliance efforts. Competent to perform the required responsibilities.
5. Importance of Competence in Safety Management
Competence in safety management is key to project success. The competence of the PSM and ISA must be demonstrated and documented to assure that they can effectively discharge their safety responsibilities.
Consequences of Incompetence or Delays:
Failure to appoint competent individuals or delay the initiation of safety management procedures can lead to:
Increased risk to project timelines and costs.
Delayed engagement with stakeholders.
Overlooked safety and environmental requirements.
Conclusion: Importance of Early Safety Management Initiation
Initiating a structured safety management process at the early stages of a project is crucial for ensuring compliance with safety and environmental standards. By identifying stakeholders, setting up a robust safety organization, ensuring compliance, and maintaining accurate documentation, the project minimizes risks, avoids delays, and maintains clear communication with all involved parties.
Project Safety Initiation: Timing
Initial Application
In an acquisition program, the procedure should be carried out early in the Concept phase. Stakeholders, system boundaries, supporting systems/arrangements, and acceptance authorities need to be identified as early as possible to support the subsequent Preliminary Hazard Identification activity (Procedure SMP04 – Preliminary Hazard Identification) and the preparation of the SMP.
The procedure can be applied at any point of the life cycle where it is necessary to initiate a formal safety management process.
Review
The registers of stakeholders and requirements should be reviewed and updated after the Outline Business Case and Full Business Case as part of the review and update of the SMP.

Copyright/Source Statement
“First, I want to point out that I’ve been referring to a standard; Military Standard 882E, a copyright-free publication. It’s a US standard and is available to download for free at many different locations. One of them is the US Defence Acquisition University. As far as I can tell, this is the official home of it now. You can search for ‘DAU’ or ‘Defence Acquisition University’ [to find it]. And when you go there, this is a search function, which is very good. You’ll find 882E very easily. But here’s the link for reference now.
So that is copyright-free. This presentation, of course, is copyright The Safety Artisan of this year (2021). But it’s also worth saying that there’s a lot more out there. There’s more help you can get than the standard by itself. The Defence Acquisition University for some reason doesn’t seem to publish much on 882E, either in the way of guidance or help on how to use this standard.

Mil-Std-882E Analysis Tasks
But also, there are ‘paid lessons’ on each one of the 10 [Mil-Std-882E] Tasks. Lessons on average are about – most of the lessons are about forty-five minutes. Some are a little bit shorter at thirty-five minutes. And the Environmental one is an hour. As is, the Health Hazard Analysis one. That’s because those are very complex tasks. So they vary from about 35 to 60 minutes in length each.
What and Why?
And for each of those old video training sessions, you will get some in-depth training on each task. Your training video will include a full description of the task, plus a commentary that I provide. You will get a full written transcript of the video as well. And if you go there, the page will tell you the benefits of each task. What it’s designed to do and how to apply it. Its pros and cons. And my expert tips from long and sometimes bitter experience on how to get the most out of these tasks. Also, pitfalls to avoid.
In Conclusion – Learning Objectives
Let’s recap, for this entire course, the five modules. You should now be able to describe your fundamental research concepts from Module One. From Module Two, you should be able to explain what a system safety approach is and does. You should be able to define what a risk analysis program is. You should be able to list the Hazard Analysis Tasks that make up a Safety Program. Or a Risk Analysis Program.
Critically, you should be able to select which tasks you need to meet your needs. And by doing that repeatedly, you should then be able to design a tailored Risk Analysis Program. And you should be able to do this for pretty much any application. And in the final module, you will have learned how to get more information. And where to find more in-depth resources on each of those 10 tasks. That’s in case you should need to go to the next level.
So, that’s what we’ve covered in this session.

Designing Your Risk Assessment Program: Transcript
We’re onto Module Four – Designing Your Program.
This module aims to show you how to design a systematic, effective strategy for Risk Analysis. An effective program for Risk Analysis that isn’t wasteful. This module is a little bit longer than the others but bear with me! This is the real meat of what I promised you. So, let’s get started.
Multiple Points of View
As I said in a previous slide, we will deal with multiple points of view. We will use multiple points of view to look at the system from many different angles.
Ten different angles, in this case, one for each task. Each of those tasks brings a different perspective. So, each task has a different purpose. What they have in common is they are all there to bring out a different aspect of the system. They are different kinds of analysis, but they all have the same aim. To identify hazards and analyze hazards.
From that, we can then identify what we need to do to control those hazards. And that, in turn, gives us safety requirements. Sometimes they’re called ‘derived safety requirements’. They need to be met for the system to be safe. That’s the whole point of what we’re doing, as mentioned before.
Which Ingredients?
But if you’ve got everything then you only need all those 10 tasks if everything is in the red. Perhaps you’ve got a very novel system. You’ve got challenging performance requirements. You’ve got lots of bespoke development. And you’ve got a very critical system that’s going to get a lot of scrutiny. So, you need all 10 only if you’ve got a development from hell. Where you’ve got a very challenging development and you need all the tools you can get.
Now, that’s fine. That’s what the standard’s designed for. But very rarely are we going to work on a program where we’re pulling out all the stops. More often, we’re going to be working on something where there are some challenging areas and some less so. And we don’t need the entire program. We don’t need all 10 tasks to achieve success. And it’s OK to tailor your safety analysis to deliver value for money. In fact, this approach is better.
So, we’ve got some options here. I’m going to take you through the bare essentials. Those are what you need to do for every safety program. The work that we would do to address new designs and new integrations. Work that we would do to address the human element. This includes both parts of human factors. That’s the human contribution to safety and the impact that the system might have on human health. So, there’s a bit of back and forth in there in the two tasks there.
Then if our system has got programmable electronic software, we might need to look at that. Or if it has data that is being developed or modified, we need to look at that too. We need to assess the safety implications of the modifications/development. We might consider combining existing systems into a system of systems. And then finally, we might have to do environmental protection. So, the bare essentials plus those five optional elements are the ones that we will look at.
The Essentials #1
Let’s start with the essentials. I’m going to say it’s axiomatic – that every program needs these three tasks. It needs Preliminary Hazard Identification. It needs Preliminary Hazard Analysis. And it needs System Requirements Hazard Analysis. The last one is about identifying safety requirements for the system.
Now, that’s a very bold statement, is it for me to say you must have these elements in every safety program? Let me justify that, first of all, before I explain it a little bit in the next slide.
The first thing to note is that you can do these tasks early on. They are quick and cheap tasks if you do them early enough. If you do them early enough, it’s low granularity. So, it can be a quick and simple analysis. And because of that, it’s cheap. But don’t let that fool you! Getting in early and thinking about Risk early gives us valuable insight. Insight that we can then take action on. So we get actionable results early enough in the program to do something about it if we do it.
The second point to note with these three is that every other task depends on their outputs. Indeed, if you’re going to successfully tailor a safety program, you need the output from these tasks. They will help you focus on what’s important and what’s less important.
Thirdly, from experience, almost every program suffers from not doing these three tasks. Whether that be well enough, early enough, or both. I’ve never been on a program where we said, ‘We did too much Preliminary Hazard Identification Analysis!’. Nor ‘We did too much identification of safety requirements!’. That has never, ever happened in more than 20 years of experience working on safety programs.
It’s always been the opposite. We wish we’d done more. We wish we’d gone in earlier with these tasks. Then we would have known something that would have helped us to make sensible decisions. Ultimately, it would have saved a lot of time and money too! Think of these essentials as an investment, because that’s what they are…

When Understanding Your Risk Assessment Standard, we need to know a few things. The standard is the thing that we’re going to use to achieve things – the tool. And that’s important because tools designed to do certain things usually perform well. But they don’t always perform well on other things. So we will ask ‘Are we doing the right thing?’ And ‘Are we doing it right?’
So, what will we do and why are we doing it? First, the use of safety standards is very common for many reasons. It helps us to have confidence that what we’re doing is good enough. We’ve met a standard of performance in the absolute sense. It helps us to say, ‘We’ve achieved standardization or commonality in what we’re doing’.
We can also use it to help us achieve a compromise. That can be a compromise across different stakeholders or different organizations. Standardization gives us some of the other benefits as well. If we’re all doing the same thing rather than we’re all doing different things, it makes it easier to train staff. This is one example of how a standard helps.
However, we need to understand this tool that we’re going to use. What it does, what it’s designed to do, and what it is not designed to do. That’s important for any standard or any tool. In safety, it’s particularly important because safety is in many respects an intangible. This is because we’re always looking to prevent a future problem from occurring. In the present, it’s a little bit abstract. It’s a bit intangible. So, we need to make sure that in concept what we’re doing makes sense and it’s coherent. That it works together. If we look at those five bullet points there, we need to understand the concept of each standard. We need to understand the basis of each one.
They’re not all based on the same concept. Thus, some of them are contradictory or incompatible. We need to understand the design of the standard. What the standard does, what the aim of the standard is, and why it came into existence. And who brought it into existence. To do what for who – who’s the ultimate customer here?
For risk analysis standards, we need to understand what kind of risks it addresses. Because the way you treat a financial risk might be very different from a safety risk. In the world of finance, you might have a portfolio of products, like loans. These products might have some risks associated with them. One or two loans might go bad and you might lose money on those. But as long as the whole portfolio is making money that might be acceptable to you. You might say, ‘I’m not worried about that 10% of my loans have gone south and all gone wrong. I’m still making plenty of profit out of the other 90%’. It doesn’t work that way with safety. You can’t say ‘It’s OK that I’ve killed a few people over here because all this a lot over here are still alive!’. It doesn’t work like that!
Also, what kind of evidence does the standard produce? Because in safety, we are very often working in a legal framework that requires us to do certain things. It requires us to achieve a certain level of safety and prove that we have done so. So, we need certain kinds of evidence. In different jurisdictions and different industries, some evidence is acceptable. Some are not. You need to know which is for your area. And then finally, let’s think about the pros and cons of the standard, what does it do well? And what does it do not so well?
System Safety Pedigree
We’re going to look at a standard called Military Standard 882E. This standard was first developed several decades ago. It was created by the US government and military to help them bring into service complex cutting-edge military equipment. Equipment that was always on the cutting edge. That pushes the limits of what you can achieve in performance.
That’s a lot of complexity. Lots of critical weapon systems, and so forth. So they needed something that could cope with all that complexity. It’s a system safety engineering standard. It’s used by engineers, but also by many other specialists. As I said, it’s got a background in military systems. These days you find these principles used pretty much everywhere. So, all the approaches to System Safety that 882 introduced are in other standards. They are also in other countries.
It addresses risks to people, equipment, and the environment, as we heard earlier. And because it’s an American standard, it’s about system safety. It’s very much about identifying requirements. What do we need to happen to get safety? To do that, it produces lots of requirements. It performs analyses of all those requirements and generates further requirements. And it produces requirements for test evidence. We then need to fulfill these requirements. It’s got several important advantages and disadvantages. We’re going to discuss these in the next few slides…

Welcome to Risk Management 101, where we’re going to go through these basic concepts of risk management. We’re going to break it down into the constituent parts and then we’re going to build it up again and show you how it’s done. I’ve been involved in risk management, in project risk management, safety risk management, etc., for a long, long time. I hope that I can put my experience to good use, helping you in whatever you want to do with this information.
Maybe you’re getting an interview. Maybe you want to learn some basics and decide whether you want to know more about risk management or not. Whatever it might be, I think you’ll find this short session really useful. I hope you enjoy it and thanks for watching.
Hi everyone and welcome to Risk Management 101. We’re going to go through these basic concepts of risk management. We’re going to break it down into the constituent parts. Then we’re going to build it up again and show you how it’s done.
My name is Simon Di Nucci and I have a lot of experience working in risk management, project risk management, safety risk management, etc. I’m hoping that I can put my experience to good use, helping you in whatever you want to do with this information. Whether you’re going for an interview or you want to learn some basics. You can watch this video and decide if you want to know more about risk management or if you don’t need to. Whatever it might be, you’ll find this short session useful. I hope you enjoy it and thanks for watching.
Topics For This Session
Risk Management 101. So what does it all mean? We’re going to break risk management down into we’ve got six constituent parts. I’m using a particular standard that breaks it down this way. Other standards will do this in different ways. We’ll talk about that later. Here we’ve got risk management broken down into; hazard identification, hazard analysis, risk estimation, risk evaluation (and ALARP), risk reduction, and risk acceptance.
Risk Management
Let’s get right on to that. Risk management – what is it? It’s defined as “the systematic application of management policies, procedures, and practices to the tasks of hazard identification, hazard analysis, risk estimation, risk and ALARP evaluation, risk reduction, and risk acceptance”.
There are a couple of things to note here. We’re talking about management policies, procedures, and practices. The ‘how’ we do it. Whether it’s a high-level policy or low-level common practice. E.g. how things are done in our organization vs how the day-to-day tasks are done? And it’s also worth saying that when we talk about ‘hazards’, that’s a safety ‘ism’. If we were doing security risk management, we could be talking about ‘threats’. We can also be talking about ‘causes’ in day-to-day language. So, we can be talking about something causing a risk or leading to a risk. More on that later, but that’s an overview of what risk management is.
Part 1
Let’s look at it in a different way. For those of you who like a visual representation, here is a graph of the hierarchical breakdown. They need to happen in order, more or less, left to right. And as you can see, there’s a link between risk evaluation and risk reduction. We’ll come on to that. So, it’s not ‘or’ it’s a serial ‘this is what you have to do’. Sometimes they’re linked together more intimately.
Hazard Identification
First of all, hazard identification. So, this is the process where we identify and list hazards and accidents associated with the system. You may notice that some words here are in bold. Where a word is in bold, we are going to give the definition of what it is later.
These hazards could lead to an accident but are only associated with the system. That’s the scope. If we were talking about a system that was an airplane, a ship, or a computer, we would have a very different scope. There would also be a different way that maybe accidents would happen.
On a more practical level, how do we do hazard identification? I’m not going to go into any depth here, but there are certain classic ones. We can consult with our workers and inspect the workplace where they’re operating. In some countries, that’s a legal requirement (Including in Australia where I live). Another option is looking at historical data. And indeed, in some countries and in some industries, that’s a requirement. A requirement means we have to do that. And we can use special analysis techniques. Now, I’m not going to talk about any of those analysis techniques today. You can watch some other sessions on The Safety Artisan to see that.
Hazard Analysis
Having done hazard identification, we’ve asked ourselves ‘What could go wrong?’. We can put some more detail on and ask, ‘How could it go wrong? And how often?’. That kind of stuff. So, we want to go into more detail about the hazards and accidents associated with this particular system. And that will help us to define some accident sequences. We can start with something that creates a hazard and then the hazard may lead to an accident. And that’s what we’re talking about. Later, we will show that using graphics can be helpful.
But again, more on terminology. In different industries, we call it different things. We tend to say ‘accident’ in the UK and Australia. In the U.S., they might call it a ‘mishap’, which is trying to get away from the idea that something was accidental. Nobody meant it to happen. Mishap is a more generic term that avoids that implication. We also talk about ‘losses’ or we talk about ‘breaches’ in the security world. We have some issues where somebody has been able to get in somewhere that they should not. And we can talk about accident sequences. Or, in a more common language, we call it a sequence of events. That’s all it is.
Risk Estimation
Now we’re talking about the risk estimation. We’ve thought about our hazards and accidents and how they might progress from one to another. Let’s think about, ‘How big is the risk of this actually happening?’. Again, we’ll unpack this further later at the next level. But for now, we’re going to talk about the systematic use of available information. Systematic- so, ordered. We’re following a process. This isn’t somebody on their own taking a subjective view ‘Look, I think it’s not that’. It’s a process that is repeatable. We want to do something systematic. It’s thorough, it’s repeatable, and so it’s defendable. We can justify the conclusions that we’ve come to because we’ve done it with some rigour. We’ve done it in a systematic way. That’s important. Particularly if we’re talking about harm coming to people or big losses.
Risk and ALARP / SFARP Evaluation
Now, risk evaluation is just taking that estimated risk just now and comparing it to something and saying, “How serious is this risk?”. Is it something that is very low? If it’s very insignificant then we’re not bothered about it. We can live with it. We can accept it. Or is it bigger than that? Do we need to do something more about it? Again, we want to be systematic. We want to determine whether risk reduction is necessary. Is this acceptable as it is or is it too high and we need to reduce it? That’s the core of risk evaluation.
Tolerability
In this UK-based standard – we’re using terminology is found in different forms around the world. But in the UK, they talk about ‘tolerability’. We’re talking about the absolute level of risk. There probably is an upper limit that’s allowed in the law or in our industry. And there’s a lower limit that we’re aiming for. In an ideal world, we’d like all our risks to be low-level risks. That would be terrific.
So, that’s ‘tolerability’. And you might hear it called different things. And then within the UK system, there are three classes of ‘tolerability’ at risk. We could say it’s either ‘broadly acceptable’- it’s very low. It’s down in the target region where we like to get all our risks. It’s ‘tolerable’- we can expose people to this risk or we can live with this risk, but only if we’ve met certain other criteria. And then there’s the risk that it’s so big. It’s so far up there, that we can’t do that. We can’t have that under any circumstances. It’s unacceptable. You can imagine a traffic light system where we have categorized our risk.
ALARP / SFARP
And then there’s the test of whether our risk can be accepted in the UK. It’s called ALARP. We reduce the risk As Low As Reasonably Practicable. And in other places, you’ll see SFARP. We’ve eliminated or minimized the risk So Far As Is Reasonably Practicable. In the nuclear industry, they talk about ALARA: As Low As Reasonably Achievable. And then different laws use different tests. Whichever one you use, there’s a test that we have to say, “Can we accept the risk?” “Have we done enough risk reduction?”. And whatever you’ve put in those square brackets, that’s the test that you’re using. And that will vary from jurisdiction to jurisdiction. The basic concept of risk evaluation is estimating the level of risk. Then compare it to some standard or some regulation. Whatever it might be, that’s what we do. That’s risk evaluation.
Risk Reduction
We’ve asked, “Do we need to reduce risk further?”. And if we do, we need to do some risk reduction. Again, we’re being systematic. This is not some subjective thing where we go “I have done some stuff, it’ll be alright. That’s enough.”. We’re being a bit more rigorous than that. We’ve got a systematic process for reducing risk. And in many parts of the world, we’re directed to do things in a certain way.
Elimination
This is an illustration from an Australian regulation. In this regulation, we’re aiming to eliminate risk. We want to start with the most effective risk reduction measures. Elimination is “We’ve reduced the risk to zero”. That would be lovely if we could do that but we can’t always do that.
Substitution
What’s the next level? We could get rid of this risk by substituting something less risky. Imagine we’ve got a combustion engine powering something. The combustion engine needs flammable fuel and it produces toxic fumes. It could release carbon monoxide and CO2 and other things that we don’t want. We ask, “Can we get rid of that?”. Could we have an electric motor and have a battery instead? That might be a lot safer than the combustion engine. That is a substitution. There are still risks with electricity. But by doing this we’ve substituted something risky for something less risky.
Isolation
Or we could isolate the hazard. Let’s use the combustion engine as an example again. We can say, “I’ll put that in the fuel and the exhaust somewhere, a long way from people”. Then it’ll be a long way from where it can do harm or cause a loss.” And that’s another way of dealing with it.
Engineering Controls
Or we could say, “I’m going to reduce the risks through engineering controls”. We could put in something engineered. For example, we can put in a smoke detector. A very simple, therefore highly reliable, device. It’s certainly more reliable than a human. You can install one that can detect some noxious gases. It’s also good if it’s a carbon monoxide detector. Humans cannot detect carbon monoxide at all. (Except if you’ve got carbon monoxide poisoning, you’ll know about it. Carbon monoxide poisoning gives you terrible headaches and other symptoms.) But of course, that’s not a good way to detect that you’re breathing in poisonous gas. We do not want to do it that way.
So, we can have an engineering control to protect people. Or we can use an interlock. We can isolate things in a building or behind a wall or whatever. And if somebody opens the door, then that forces the thing to cut out so it’s no longer dangerous. There are different things for engineering controls that we can introduce. They do not rely on people. They work regardless of what any person does.
Administrative / Procedural Controls
Next on the list, we could reduce exposure to the hazard by using administrative controls. That’s giving somebody some rules to follow a procedure. “Do this. Don’t do that.” Now, that’s all good. We can give people warning signs and warn people not to approach something. But, of course, sometimes people break the rules for good reasons. Maybe they don’t understand. Or, maybe they don’t know the danger. Perhaps they’ve got to do something or maybe the procedure that we’ve given them doesn’t work very well. It’s too difficult to get the job done, so people cut corners. So, procedural protection can be weak. And a bit hit-and-miss sometimes.
Personal Protective Equipment
Finally, we can give people personal protective equipment. We can give them some eye protection. I’m wearing glasses because I’m short-sighted. But you can get some goggles to protect your eyes from damage. Damage like splashes, flying fragments, sparks, etc. We can have a hard hat so that if we’re on a building site and something drops from above on us that protects the old brain box.
It won’t stop the accident from happening, but it will help reduce the severity of the accident. That’s the least effective. We’re doing nothing to prevent the accident from happening. We’re reducing the severity in certain circumstances. For example, if you drop a ton of bricks on me, it doesn’t matter whether I’m wearing a hard hat or not. I’m still going to get crushed. But with one brick, I should be able to survive that if I’m wearing a hard hat.
Risk Acceptance
Let’s move on to risk acceptance. At some stage, if we have reduced the risk to a point where we can accept it. That is, we can live with it and we’ve decided that we’re going to need to do whatever it is that is exposing us to the risk. We need to use the system. For example, we want to get in our car to enable us to go from A to B quickly and independently. So, we’re going to accept the risk of driving in our car. We’ve decided we’re going to do that. We make risk-acceptance decisions every day, often without thinking about it. We get in a car every day on average and we don’t worry about the risk, but it’s always there. We’ve just decided to accept it.
But in this example, it’s not an individual deciding to do something on the spur of the moment. Nor is it based on personal experience. We’ve got a systematic process where a bunch of people come together. The relevant stakeholders agree that a risk has been assessed or has been estimated and has been evaluated. They agree that the risk reduction is good enough and that we will accept that risk. There’s a bit more to it than you and I saying “That’ll be alright.”
Part 2
Let’s summarise where we’ve got to. We’ve talked about these six components of risk management. That’s terrific. And as you can see, they all go together. Risk evaluation and risk reduction are more tightly coupled. That’s because when we do some risk reduction, we then re-evaluate the risk. We ask ‘Can we accept it?’. If the answer is ‘No.’ we need to do some more work. Then we do some more risk reduction. So those tend to be a bit more coupled together at the end. That’s the level we’ve got to. We’re now going to go to the next level.
So, we’re going to explain these things. We’ve talked about hazard identification and hazard analysis, but what is a hazard? And what is an accident? And what is an accident sequence? We’re going to unpack that a bit more. We’re going to take it to the next level. And throughout this, we’re talking about risk over and over again. Well, what is ‘risk’? We’re going to unpack that to the next level as well.
This is a safety standard. We’re talking about harm to people. How likely is that harm and how severe might it be? But it might be something else. It might be a loss or a security breach. Or a financial loss, a negative result for our project. We might find ourselves running late. Or we’re running over budget. We might be failing to meet quality requirements. Or we’re failing to deliver the full functionality that we said we would. Whatever it might be.
Hazard
So, let’s unpack this at the next level. A hazard is a term that we use, particularly in safety. As I say, we call it other things in different realms. But in the safety world, it’s a physical situation or it’s a state of a system.
As it says, it often follows from some initiating event that we may call a ‘cause’. The hazard may lead to an accident. However, the key thing to remember is once a hazard exists, an accident is possible, but it’s not certain. You can imagine the sort of cartoon banana skin on the pavement gag. Well, the banana skin is the hazard. In the cartoon, the cartoon character always steps on the banana skin. They always fall over the comic effect. But in the real world, nobody may tread on the banana skin and slip over. There could be nobody there to slip over all the banana skin. Or even if somebody does, they could catch themselves. Or they fall, but it’s on a soft surface and they don’t hurt themselves so there’s no harm.
So, the accident isn’t certain. And in fact, we can have what we call ‘non-accident’ outcomes. We can have harmless consequences. A hazard is an important midway step. I heard it called an accident waiting to happen, which is a helpful definition. An accident waiting to happen, but it doesn’t mean that the accident is inevitable.
Accident
But accidents can happen. Again, the ‘accident’, ‘mishap’, or ‘unintended event’. Something we did not want or a sequence of events that caused harm. And in this case, we’re talking about harm to people. And as I say, it might be a security breach. It might be a financial loss or reputational damage. Something might happen that is very embarrassing for an organization or an individual. Or again, we could have a hiccup with our project.
Harm
But in this case, we’re talking about harm. With this kind of standard, we’re using what you might call a body count approach to the harm. We’re talking about actual death, physical injury, or damage to the health of people.
This standard also considers the damage to property and the environment. Now, very often we are legally required to protect people and the environment from harm. Property less so. However, there will be financial implications of losses of property or damage to the systems. We don’t want that. But it’s not always criminally illegal to do that. Whereas usually, hurting people and damaging the environment is. So, this is ‘harm’. We do not want this thing to happen. We do not want this impact.
Safety is a much tougher business in this instance. If we have a problem with our project, it’s embarrassing but we could recover it. It’s more difficult to do that when we hurt somebody.
Risk
And always in these terms, we’re talking about ‘risk’. What is ‘risk’? Risk is a combination of two things. It’s a combination of the likelihood of harm or loss and the severity of that harm or loss. It’s those two things together. And we’ve got a very simple illustration here, a little table. And they’re often known as a risk matrix but don’t worry about that too much. Whatever you want to call it. We’ve got a little two by two table here and we’ve got likelihood in the white text and severity in the black.
Low Risk
We can imagine where there’s a risk where we have a low likelihood of a ‘low harm’ or a ‘low impact’ accident or outcome. We say, ‘That’s unlikely to happen, and even if it does not much is going to happen.’ It’s going to be a very small impact. So, we’d say that that’s a low risk.
Then at the other end of the spectrum, we can imagine something that has a high likelihood of happening. And that likelihood also has a high impact. Things that happen that we definitely do not want to happen. And we say, ‘That’s a high risk and that’s something that we are very, very concerned about.’
Medium Risk
And then in the middle, we could have a combination of an outcome that is quite likely, but it’s of low severity. Or it’s of high severity, but it’s unlikely to happen. And we say, ‘That’s a medium risk’.
Now, this is a very simplified matrix for teaching purposes only. In the real world, you will see matrices that are four by four, five by five, or even six by six, or combinations thereof. And in security where they talk about threat and vulnerability and the outcomes. Here, you might see multiple matrices used. They use multiple matrices to progressively build up a picture of the risk. They use matrices as building blocks. So, it may not be only one matrix used in a more complex thing you’ve got to model. But here we’ve got a nice, simple example. This illustrates what risk is. It’s a combination of severity and likelihood of harm or loss. And that’s what risk is, fundamentally. And if we have a firm grasp of these fundamentals, it’ll help us to reason and deal with almost anything. With enough application.
Accident Sequence
Now, let’s move on and talk about accident sequences. We’re talking about a progression in this case. We’re imagining a left-to-right path. A progression of events that results in an accident. This diagram, which looks like a bow tie, is meant to represent the idea that we can have one hazard. There might be many causes that lead to this hazard. There might be many different things that could create the hazard or initiate the hazard. And the hazard may have many different consequences.
Consequences
As I’ve said before, nothing at all may happen. That might be the consequence of the hazard. Most of the time that’s what’s going to happen. But there may be a variety of consequences. Somebody might get a minor injury or there might be a more serious accident where one or more people are killed. A good example of this is fire. So, the hazard is the fire. The causes might be various. We could be dealing with flammable chemicals, or a lightning strike, or an electricity arc flash. Or we could be dealing with very high temperatures where things spontaneously burst into flames. Or we could have a chemical in the presence of pure oxygen. Some things will spontaneously burst into flames in the presence of pure oxygen. So there’re a variety of causes that lead to the fire.
An Example
And the fire might be very small and burn itself out. It causes very little damage and nobody gets hurt. Or it might lead to a much bigger fire that, in theory, could kill lots of people. So, there’s a huge range of consequences potentially from one hazard. But the accident sequence is how we would describe and capture this progression. From initiating events to the hazard to the possible consequences. And by modeling the accident sequence, of course, we can think about how we could interrupt it.
Part 3
We’ve broken risk management down into those six constituent parts. We’ve gone to the next level, in that we’ve sort of gone down to the concepts that underpin these things. These hazards, the accidents, and the accident sequence. We’ve talked about risk itself and what we don’t want to happen. The harm, the loss, the financial loss, the embarrassment, the failed or late or budget project, a security breach, the undesired event, etc. We had an objective which was to do something safely or to complete a project and the risk is that that won’t happen. That there’ll be an impact on what we were trying to do that is negative. That is undesirable.
There are just only more concepts that we need to look at to complete the pattern, as you can see. We’ve been talking about the system. And we’ve been talking about doing things systematically. Then a system works in an operating environment. So, let’s unpack that.
System
First of all, we have a system. The system is going to be a combination of things. I wouldn’t call a pen or a pencil a system. It’s only got a couple of components. You could pull it apart. But it’s too simple to be worth calling it a system. We wouldn’t call it a pen system, would we? So, a system is something more complex. It’s a combination of things and we need to define the boundary. I’ll come back to that.
But within this boundary, we’ve got some different elements in the system that work together. Or they’re used together within a defined operating environment. So, we’re going to expose this system to a range of conditions in which it is designed to work. The intention is the system is going to do whatever it does to perform a given task. It can do one defined task or achieve a specific purpose.
I talked before about getting in our car. A car is complex enough to be called a system. We get in our car and we drive it on the roads. Or if we’ve got a four-wheel drive, we can drive Off-Road. Or we can use it in a more demanding operating environment to achieve a specific purpose. We want to transport ourselves, and sometimes some stuff, from A to B. That’s what we’re trying to do with the system.
Within the System
And within that system, we may have personnel/people, we may have procedures. A bunch of rules about how you drive a car legally in different countries. We’ve got materials and physical things – what the car is made of. We could have tools to repair it, and change wheels. We’ve got some other equipment, like a satnav. We’ve got facilities. We need to take a car somewhere to fill up with fuel or to recharge it. We’ve got services like garages, repairs, servicing, etc. And there could be some software in there as well. Of course, these days in the car, there’s software everywhere in most complex devices.
So, our system is a combination of lots of different things. These things are working together to achieve some kind of goal or some kind of result. There’s somewhere we want to get to. And it’s designed to work in a particular operating environment. Cars work on roads really well. Off-road cars can work on tracks. Put them in deep water, they tend not to work so well. So, let’s talk about that operating environment.
Operating Environment
What we’ve got here, is the total set of all external, natural, and induced conditions. (That’s external to the system, so outside the boundary.) So, it might be these conditions-. It might be natural or it might be generated by something else, which a system is exposed to at any given moment. We need to get a good understanding of the system, the operating environment, and what we want it to do.
If we have a good understanding of those three things, then we will be well on the way to being able to understand the risks associated with that system. That’s one of the key things with risk management. If you’ve got those three things, that’s crucial. You will not be able to do effective risk management if you don’t have a grasp of those things. And if you do have a thorough grasp of those things, it’s going to help you do effective risk management.
Conclusion
So, we’ve talked about risk management. We’ve broken it down into some big sections. Those six sections; the hazard identification; analysis; risk estimation; evaluation; reduction; and acceptance. We’ve seen how those things depend on only a few concepts. We’ve got the concepts of ‘hazards’, ‘risks’, and ‘accidents’. As well as the undesirable consequences that the risk might result in. The risk is measured based on the likelihood and severity of that harm or loss occurring.
When we’re dealing with a more complex system, we need to understand that system and the environment in which it operates. Of course, we’ve put it in that environment for a purpose. And that unpacking has allowed us to break down quite a big concept, risk management. A lot of people, like myself, spend years and years learning how to do this. It takes time to gain experience because it’s a complex thing. But if we break it down, we can understand what we’re doing. We can work our way down the fundamentals. And then if we’ve got a good grasp of the fundamentals, that supports getting the more complex stuff right. So, that’s what risk management is all about. That’s your risk management 101 and I hope that you find that helpful.

In this module, System Safety Risk Analysis, we’re going to look at how we deal with the complexity of the real world. We do a formal risk analysis because real-world scenarios are complex. The Analysis helps us to understand what we need to do to keep people safe. Usually, we have some moral and legal obligation to do it as well. We need to do it well to protect people and prevent harm to people.
To start with, here’s a little definition of system safety. System safety is the application of engineering and management principles, criteria, and techniques to achieve acceptable risk within a wider context.
This wider context is operational effectiveness – we want our system to do something. That’s why we’re buying it or making it. The system has got to be suitable for its use. We’ve got some time and cost constraints and we’ve got a life cycle. We can imagine we are developing something from concept, from cradle to grave.
And what are we developing? We’re developing a system. An organization of hardware, (or software) material, facilities, people, data and services. All these pieces will perform a designated function within the system. The system will work within a stated or defined operating environment. It will work to produce specified results.
We’ve got three things here: a system; the operating environment in which it is designed to work; and, we have its function or application. Why did we buy it, or make, it in the first place? What’s it supposed to do? What benefits is it supposed to bring humankind? What does it mean in the context of the big picture?
That’s what a system is. I’m not going to elaborate on systems theory or anything like that. That’s a whole big subject on its own. But we’re talking about something complex. We’re not talking about a toaster. It’s not consumer goods. It’s something complicated that operates in the real world. And as I say, we need to understand those three things – system, environment, purpose – to work out Safety.
