Designing a Useful and Effective Proof Test: Part 2

Recording Date: July 2015

A continuation of the “Designing a Useful and Effective Proof Test,” this webinar will look at how to handle final elements that are made up of several distinct devices. We will review functional failure modes by device and provide a methodology on how to determine the overall proof test effectiveness when multiple devices are used. The webinar will also map failure modes from components, to devices, and elements to illustrate how accurate proof test coverage values can be determined.
