System Safety Risk Analysis

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.

Aim: How do we deal with real-world complexity?

  • What is System Safety?
  • The Need for Process;
  • A Realistic, Useful, Powerful process:
  • Context, Communication & Consultation;
  • Monitoring & Review, Risk Treatment; and
  • Required Risk Reduction.

What is System Safety?

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.

Introduction to System Safety Risk Assessment

In this ‘Introduction to System Safety Risk Assessment’, we will pull together several key ideas.

First, we’ll talk about System Safety. This is safety engineering done in a Systems Engineering Framework. We are doing safety within a rigorous process.

Second, we’re talking about Risk Assessment. This is a term for putting together different activities within another process. This process may be basic, or it might be quite sophisticated, as illustrated, below.

Third, and finally, we will put all this together into a System Safety Program. This is hinted at in the diagram, above, but a real system safety program needs to do a lot more than this. It needs to tie into the project it supports, to systems engineering, to resources, quality, V&V, etc. Designing such a program is complex, so we typically follow a standard, like Mil-Std-882E.

You can hear more about this in the introductory video, below.

Introduction

Hello,

Welcome to this course on Systems Safety Risk Analysis Programs. I’m Simon Di Nucci, The Safety Artisan, and I’ve been a safety engineer and consultant for over 20 years. I’ve worked on a wide range of safety programs doing risk analysis on all kinds of things. Ships, planes, trains, air traffic management systems, software systems, you name it.

I’ve worked in the U.K., in Australia, and on many systems from the U.S. I’ve also spent hundreds of hours training hundreds of people on safety. And now I’ve got the opportunity to share some of that knowledge with you online.

So, what are the benefits of this course?

First of all, you will learn about basic concepts. About system safety, what it is and what it does. You will know how to apply a risk analysis program to a very complex system and how to manage that complexity. So, that’s what you’ll know.

At the end of the course, you will also be able to do things that you might not have been able to do before. You will be able to take the elements of a risk analysis program and the different tasks. You can select the right tasks and form a program to suit your application, whatever it might be. Whether you might:

  • Have a full, high-risk bespoke development system,
  • Be taking a commercial system off the shelf and doing something new with it, or
  • Take a product and use it in a new application or a new location.

Whatever it might be, you will learn how to tailor your risk analysis program. This program will give you the analyses you need. And to meet your legal and regulatory requirements. Once you’ve learned how to do this, you can apply it to almost any system.

Finally, you will feel confident doing this. I will be interpreting the terminology used in the tasks and applying my experience. So, instead of reading the standard and being unsure of your interpretation, you can be sure of what you need to do. Also, I will show you how you can get good results and avoid some of the pitfalls.

These are the three benefits of the Course

  1. You will know what to do.
  2. You will be able to perform risk program tasks, and
  3. You’ll feel confident doing those tasks.

At the end of the course, I will also show you where to find further resources. There are free resources to choose from. But there are also paid resources for those who want to take your studies to the next level. I hope you enjoy the course.
