Do Companies Need Robust Design?
I know what Robust Design is, but do companies really need it? If so, who needs it and why? This video helps address that question. [Read more…]
FMEA Q and A – Where do reliability requirements belong in an FMEA?
FMEA Q and A
Can you take into account reliability or durability functions in an FMEA? How can this be done? A reader asks this question, and it is discussed and answered in this FMEA Q and A article.
“A prudent question is one-half of wisdom.”

How to analyze Design of Experiment Data
Many times, a complete analysis is not performed with DOE testing. However, the learning value is substantial for model building situations and only takes a small amount of additional time if you know what you are looking for. In this video, we give an overview of the key items we look for to develop break throughs in product and process development. This same process has been used for the majority of our 25+ years of DOE experience. [Read more…]
Understanding RPN Limitations – Problems and Solutions
In this week’s FMEA problems and solutions article, the intermediate problem challenges readers to prioritize a series of RPNs (with their corresponding S, O, and D). In the advanced problem, readers are asked to weigh in on a fictitious debate between advocates of traditional RPN, and advocates of criticality assessment, using only severity and occurrence.
If you haven’t yet read the article titled “Prioritizing risk for corrective actions in an FMEA – Know before you go!“, you can access it by clicking on the link.

Accelerated Tests
Introduction
Reliability and durability are essential in today’s competitive market place. However, component reliability verification tests and system durability tests take a long time, cycles, or miles to complete. This puts these tests in direct conflict with program timing, product development budgets, and limited testing resources. To minimize this conflict, it is essential to accelerate these tests.

We at Perry’s Solutions, Inc. have these key traits and exist as a business because we are often being used in this role – previously as a corporate employee and now as a consultant. [Read more…]
Extended Bogy Testing
Extended Bogy Testing
Introduction
Extended bogy testing builds on test to bogy (TTB), discussed in a prior article. TTB focused on calculating the number (N) of parts tested to one life bogy, with 0 failures allowed, to a specified reliability (R) and confidence (C) levels.
Using TTB to verify conformance to high reliability and confidence targets requires very large sample sizes, increasing testing cost. The capacity to test large samples may require large facility capital expenditures. Also, the zero failures allowed paradigm removes the opportunity to learn about product failure modes and the opportunity to improve the product through design or manufacturing process changes.
This article focuses on extended bogy test plans as an alternative to TTB.
Resolution II Design of Experiment Set Up Danger!
Design of Experiments classes always talk about Resolution III and higher designs. But what is a Resolution II design? We show what it is – and show that it is actually used quite a bit! Should be used with caution as it does not provide understanding.

Good Networking – Radio Interview
This video gives some tips regarding networking. It applies to finding a job or for obtaining clients in a consulting business.
This was created for the large number of people I know who have been displaced from a job. Many wanted advice based on my experiences and with my daily effort to build my consulting business. Not being able to have lunch with everyone, I created this video to help them get started. It has been helping people, so hope you can find value. It may also turn into a book at some point.
