SOR 463 What is an Outlier?
What is an Outlier?
Abstract
Chris and Fred discuss the concept of an ‘outlier.’ Depending on the definition, an outlier is something that is different, non-representative or somehow separate from the ‘main body’ of something. We often use the term ‘outlier’ when it comes to statistical analysis of something – specifically when we see something that is beyond what we expect to see. So what do we do with ‘outliers’ … particularly when it comes to reliability analysis? It may be tempting to exclude them (particularly if it makes the outcome of your analysis ‘better’!). We have not seen the exclusion of ‘outliers’ have a happy ending when it comes to reliability. Would you like to learn more? Listen to this podcast!

High Temperature Environmental or Reliability Testing
Abstract
Chris and Fred discuss the difference between ‘environmental’ and ‘reliability’ testing … but is there a difference? This question was raised by one of our listeners – which means this is a topical question. A question that could apply to you. Now some may seem that we are dodging the question in this podcast – because we think it is all about intent and not a category. That is – every test should be an experiment. It should be constructed to answer a question, or provide information for a specific decision. And once you focus on the information you are trying to provide – what is the point in classifying something as ‘environmental’ versus ‘reliability’ testing? Each test could conceivably be neither, one, or both. Listen to this podcast if you want to learn more.

SOR 421 Specification Requires Testing… Really?
Specification Requires Testing… Really?
Abstract
Chris and Fred discuss scenarios where it is (for whatever reason) impossible to demonstrate reliability through testing. Some organizations think that if you can’t demonstrate through testing … then it can’t be a requirement that appears in a specification. So … does this mean that the customer can’t get something that is reliable if we can’t test for it? … can customers even ask for it? Of course they can. The customer knows what they want. Everyone needs to understand that you can verify performance through activities that don’t involve testing (… like analysis). This is how it works for nuclear power plants … so what makes your organization special? Listen to this podcast if this intrigues you.
