Reliability and Product Development
Abstract
Carl and Fred discussing the subject of how to integrate reliability into your company’s product development process.
Key Points
Join Carl and Fred as they discuss how every company has a defined process to develop products, and reliability needs to fit into that process.
Topics include:
- Reliability must be designed-in to products and processes
- How do you accomplish DFR?
- What are the barriers to DFR?
- Translating from reliability to measurable design characteristics
- How can DFR be integrated into design tasks during product development?
- Role of reliability in concept development stage
- Surfacing predominant failure mechanisms early in product development
- Integrating reliability into design reviews
- What will fail, when, and how will you know?
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.

for Product Development Process and Reliability Integration i was at a company where the PDP for each team was very detailed. currently im at a company where im the first Rel engineer, and they are working to get a PDP process integrated. But no matter, for both companies, usually is User Experience and ID teams are the ones who design the next product and will always be involved at a phase where Product Design team would start having CADs. I think, in order to get involved earlier than that I need great amount of experience, which in my case is not quite true.
Also, from my experience, my Reliability test plan development is based on DFMEA (whenever there is one). I think that is very hard to develop a test plan to get life predictions if I dont have failure mode and Ea (at least) for the part im trying to test, or if the part is a module that has different materials, then it gets even more complicated.
I do have a question, and since im still somewhat junior, how can I change the image of Test Engineer, to Reliability Engineer? is been pretty hard for me to make realize most of the people of my team that im not just a test engineer… that is being pretty disappointing and discouraging, any advice?
Hello Daniela,
Excellent comments and questions.
My first response is regarding your comment that getting involved before CAD requires a great amount of experience. Many of the tools of Design for Reliability begin in the requirements phase. Fred and I are writing a book on reliability management, and the early chapters are posted on Accendo Reliability. Click on this link to see how you can review the early chapters and receive a copy. These chapter will show you how to identify the right tools to design in reliability, and begin before CAD timing.

Regarding your comment about FMEA, you are absolutely correct. A proper DFMEA is an excellent input to the Reliability Test Plan. It identifies which tests need improvement based on failure modes and mechanisms of most concern.
You asked, “how can I change the image of Test Engineer, to Reliability Engineer? It is pretty hard for me to make realize most of the people of my team that I’m not just a test engineer… that is being pretty disappointing and discouraging, any advice?”
I began my career as a test engineer and moved to reliability engineer. My suggestion is to continue to learn the fundamentals of reliability and apply them to your testing. If you can apply reliability principles properly to testing, you will add value to the project team and improve your credibility. Once you have done that, you can help the design team improve their designs to ensure they do not fail by informing them of the most important failure mechanisms.
Good luck to you!
Carl
