If you look at true "safety critical'" features of automobiles you'll note that they generally have backups.
So if design is the issue, consider whether there are backup systems
on the product; maybe the initial severity assessment was in error.
(Errors can be corrected, with explanation. As noted above, you can't
just reduce a severity without a change, so you'd have to justify
I guess I don't follow where the "backyp system" affects the Severity rating. Doesn't it really affect the Occurence?? As Dave said - there is still the Potential
for the Failure Mode to happen, even with a backup system, so how has the Severity been impacted?
Just looking for clarification.
