Once a product is launched it’s time to understand how the product is performing. The design is done, the assembly process is working, now we can focus on answering the question: is the product hitting reliability targets or not?
Thus, we do field data analysis. [Read more…]
There are three approaches to set tolerance limits for design elements. Each has ramifications for the eventual manufacturability and reliability performance. Design for manufacturability and reliability hinge of getting design tolerances set correctly. [Read more…]
The survival of an individual item is difficult to determine. Use and environmental conditions along with material and assembly differences count. Let’s explore how to model and use the naturally occurring variability to improve reliability performance. [Read more…]
The local weather affects your products and systems. Knowing the weather helps you plan your wardrobe for the day. Likewise, knowing the weather helps you design a product or system that is able to thrive in the weather conditions it will experience. [Read more…]
As a reliability professional you will be asked to teach. You are part teacher, coach, mentor, and expert. Being effective enhances the understanding of reliability objectives and method to achieve them. Let’s explore becoming an amazing teacher. [Read more…]
A good physics of failure (PoF) model helps you understand the impact of stresses on the time to failure distribution for a specific failure mechanism. Let’s discuss PoF models, including how to create and use them effectively. [Read more…]
Standards provide guidance, a common language, and a bit of confusion. Using the right standard and using it well can help your reliability program. Using standards poorly will harm your ability to create reliable products.

Testing is expensive. Reliability testing is often complex. Let’s break down the basic of planning and conducting reliability testing the provides meaningful results in a cost-effective and timely manner. Let’s do testing right.

People not only use your product, they assemble it, move and store it. If a person is not able to interact with your product, with or without the manual, they may consider your product a failure. Designing in the ability for an individual to properly use your product is the art of considering human factors. [Read more…]
If your product is stronger than the applied stress, it should work. The concept of the stress/strength relationship is well known, yet did you know both stress and strength change over time? Let’s use the best information and tools for this analysis. [Read more…]
Statistical Process Control charts have been called the Voice of the Process. Progressive manufacturers utilize control charts to “listen” to their processes so that potentially harmful changes will be quickly detected and rectified. [Read more…]
Product failures occur due to the material or component variability. The steel in a bracket is more brittle then optimal, or the capacitance is on the low side of an acceptable range. Designing a product with variation in mind enables the creation of a reliable product. [Read more…]
Stress screening, highly accelerated stress screening, burn-in, are expensive activities and to be avoided. Yet stress screening does have a valuable purpose in specific circumstances. Let’s talk about when and why you may conduct stress screening.
[Read more…]
An element of a complete reliability goal statement involves a product’s environment and use conditions. The ability to define these clearly during the design process is not always easy yet a valuable addition to your reliability program.

A common question about reliability testing is “what is the sample size?” It is also a difficult question to answer well. The right sample size is a balance between cost, accuracy, and variability. In some cases, we also consider the time to results.
