What role does ‘wishful thinking’ play in the interpretation of reliability test results? Hopefully, none. A well-designed test will likely provide meaningful results. You and your team may not like the results, yet the results will be clear.
From success testing to design of experiments based accelerated life testing, from shipping and storage testing to ongoing reliability testing, we do a lot of testing. In order to create tests and results that are meaningful we need to both design and execute the test well, then most importantly, interpret the results accurately.
The often-overlooked process of making assumptions is our focus for the discussion. What assumptions are we making and how differences from those assumptions will impact how we may interpret the results. Let’s discuss a few cases and highlight what to consider, assume, and check as you prepare to interpret your test results.
