Why Do We Use Outdated Methods
This is the first part of two podcast that Kirk and Fred have on a recent ASQ Newsletter with sample CRE (Certified Reliability Engineer) test questions at the end and how outdated and for Kirk how it is perpetuating irrelevant and misleading reliability paradigms
Join Kirk and Fred as they discuss the CRE training process and testing and Fred’s long involvement in the CRE world.
- Fred talks about the his reasons and process of getting the CQE (Certified Quality Engineer) and teaching the courses that will allow you to pass the CRE test, which was out of date 20 years ago and his efforts to change the CRE body of knowledge to make it more current and relevant.
- The large amount of CRE information and direction Fred believes may be misleading but some information is still beneficial.
- Kirk discusses how he only found out what the CRE world was all about long after he had been a repair technician in a calibration lab and a field service engineer in capital semiconductor manufacturing systems, had met and worked with Gregg Hobbs, PhD., creator of the methods of HALT and HASS at the Storage Technology Company in 1989.
- Models of wear out and material loss in mechanical systems such as tires or brakes can be modeled and those models are relevant, but the many mechanisms in silicon, solder, or PCB assemblies have more life entitlement than will ever be needed. Technology obsolescence comes long before wear out in most electronic systems.
Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics. Join us as we discuss topics ranging from design for reliability techniques to field data analysis approaches.

Looking forward to part two of this discussion and what to do about this problem.
Kirk Gray says
Thanks for your comment. The second part is much more challenging, and I have been fighting for change most of my reliability engineering career.
In part 2, I’m sure you and Fred will talk about what practical methods are recommended and include those that you are seeing being effectively used today, instead of the outdated methods discussed and taught via the CRE BoK.
I just re-read all of the training material I had covering the CRE exam. I still don’t know how and where to apply most of it.
I just ordered your relatively new HALT/HASS book. I’m confident I’ll gain some practical and useful information from it.
Kirk Gray says
And thanks for ordering my book.
I hope you get a lot of useful information from it.
