Choosing a Confidence Level for Test using FMEA

We’re developing requirements for our product, including setting reliability requirements. Or we’re setting acceptance criteria for our test plans.

What confidence levels do we choose? We don’t have to blindly set them - we can base it off the risks of failure, using our FMEA (failure mode effects analysis).

We should choose a confidence level for our requirements or their test plans. We can associate that confidence level with the level of risk associated with our product. FMEA is a great tool for us to refer to, to help us choose a relevant confidence level by basing our decision on one or more metrics that the FMEA can provide.
