There is a rather large family of test methods associated with Qualitative Accelerated Tests. They're also known as RETs (or Reliability Enhancement Tests). Today, we’re focused on the models that are used to help us with the design.

We talk about environmental stress testing and remind ourselves a little about HALT.Visit the podcast blog for a transcript.If you'd like to explore some of today's topics more, then I recommend these other QDD podcasts.Episode 6: HALT!
