Inspection in this case is a proof that the design you're certifying is fit-for-purpose.
So in your example, it would show that the loading and stresses on your washing lines were sufficiently low to meet the safety margin of the bridge.
Certification of safety-related and medical devices is not a check-box exercise, it looks at the dynamic and static behaviour of your system as a whole (not just the software).
- michaelt 10y agoPerhaps I wasn't clear in my analogy. I mean the washing lines weren't fit for purpose (just like the insecure comms wasn't fit for purpose) but the inspection didn't identify them as unfit for purpose (just like the inspection didn't identify the insecure comms as unfit for purpose) Given that something unfit for purpose was certified, certification doesn't prove something is fit for purpose. Of course, certification may indicate something is probably more fit for purpose than something that failed the same certification or didn't attempt it.
- TickleSteve 10y agoThe inspection of the washing-line design should have identified this... unless human-failure. So your point is: "we don't know what we don't know"? True. I see no way around this.
