Christian,
the problem is often when your software has to be integrated into other
software and systems, which is almost always the case in life-critical systems.
If your software is controlling a critical component like an X-ray beamer for
instance, you’d better be prepared for all kinds of rubbish that can enter your
software.
The same holds for cockpit displays for instance; they need to take in a lot of
external signals, and that can go wrong.
It is more like ‘Be prepared for the worst and nothing will happen’.
Cheers,
Kurt
