In this special episode of Quality during Design Redux, we're pulling episodes from our archive about test results analysis. 

In our Season 1 - Episode 93  titled "The Fundamental Thing to Know from Statistics for Design Engineering", we talked about hypothesis testing: how it is used for lots of data analysis techniques. 

The next 4 episodes of this QDD Redux are taking the next steps.

If we're not careful with or ignore failure modes, we can choose the wrong reliability model or statistical distribution. If our product performance is close to the required limits and/or we need a very accurate model, this could be a big problem.

We talk about the importance of failure modes and step-through a tensile-test example to explore these other topics:

• competing failure modes
• suspensions
• independent vs. dependent
• reliability block diagrams

The podcast blog includes extra useful information/links.
