The term “Project Management” has been overused in recent years. Many people claim to be one, but what does it mean. For us, it is a very broad and very impactful role. It covers all aspects of project execution and success. It also involves deep customer interaction. [Read more…]
This article culminates the first major milestone in the Inside FMEA series of articles: the “FMEA Fundamentals Series.” The next series is called: “FMEA Preparation Series.”

How do you interpret a DOE? With a few principles it becomes easier to understand. Very important to consider the intangibles. It is not a pure mathematical problem. It is critical because this is where the value from the testing shows up! [Read more…]
A state variable is a parameter that is categorized into a countable number of defined states. Examples would include transmission gear states, PRNDL positions, ignition switch states, and others. Sometimes continuous variable, like pedal positions, may be binned into discrete states to be displayed as a histogram. State change timing is unpredictable since vehicle operation is highly variable. A way to deal with this data is Markov Analysis.
We have promoted this definition for Design of Experiments for a long time. This video provides the background of what each phrase is important. [Read more…]
When testing, it is good to know your options. The Advanced tools of Design of Experiments are good to consider. What are they, why should you consider them, and when should they be used. Those are the topics we will discuss in this video. [Read more…]
How do you know if YOU need robustness? It is a combination of testing and analysis. Can you afford it? How do you decide? This video helps set the stage for this decision. [Read more…]
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…]
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.”

When your engineering project struggles, how do you respond? This video provides a sports analogy to the situation. Get back to the fundamentals – and Design of Experiments can be part of that process.

After years of consulting, what motivates us now? This video discusses those areas of interest for us. Constant learning and challenge keeps us going! [Read more…]
Why did we start the company – and why this specific company. This video provides the answer. www.PerrysSolutions.com [Read more…]
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…]
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.

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.
