Learn System of Systems Hazard Analysis.
In this full-length (38-minute) session, The Safety Artisan looks at Systems-of-Systems Hazard Analysis, or SoSHA, which is Task 209 in Mil-Std-882E. SoSHA analyzes collections of systems, which are often put together to create a new capability, which may be enabled by human brokering between the different systems. We explore the aim, description, and contracting requirements of this Task, and an extended example to illustrate SoSHA. (We refer to other lessons for special techniques for Human Factors analysis.)
Hello everyone and welcome to the Safety Artisan. I’m Simon and today we’re going to be talking about System of Systems Hazard Analysis – a bit of a mouthful that. What does it actually mean? Well, let’s see.
System of Systems Hazard Analysis
So, for Systems of Systems Hazard Analysis, we’re using Task 209 as the description of what to do taken from a military standard, 882E. But to be honest, it doesn’t really matter whether you’re doing a military system or a civil system, whatever it might be – if you’ve got a system of systems, then this will help you to do it.
Topics for this Session
Looking at what we’ve got coming up. So, we look at the purpose of system-of-systems HA.
(I’m talking about when we take different systems that we’ve developed elsewhere, e.g. platforms, electronic systems, whatever it might be, and we put them together. Usually, with humans gluing the system together somewhere, it must be said, to make it all tick and fit together.)
Then we want this collection of systems to do something new, to give us some new capability, that we didn’t have before. So, that’s what I’m talking about when I say a system of systems. I’ll show you an example, we’ve got a couple of slides on task description, a couple of slides or documentation, and a couple of slides on contracting. Task 209 is a very short task, and therefore I’ve decided to go through an example.
So, we’ve got seven slides of an example of a system of systems, safety case, and safety case report that I wrote. And hopefully, that will illustrate far better than just reading out the description. And that will also give us some issues that can emerge with systems of systems and I’ll summarize those at the end.
