I am rather surprised, since you have to do with safety cases, that you don't appear to know of them. They provide the software with which most of the MoD safety cases are nowadays prepared.

Because, as you will know, not speaking entirely from within your hat on safety case matters, operational safety is a different matter from fit-for-purpose certification. I wonder why you even asked the question?
To your comment on WBA:

You imagine you can infer someone's capabilities from their day job? Maybe you can. BTW, I am curious to know which societies I belong to you think are "glorious".
The industrial users of WBA are very happy with it. That's good enough for me (and the tech-transfer company's pocketbook).

How insightful! Can we cite you as a reference?
