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.

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.

The Weibull distribution is a versatile tool to analyze time to failure data. Like any tool, it could be wielded well or not so well. In this short webinar let’s discuss when and why you would use Weibull analysis, the basic process, and limitations.

Some products and systems are just dangerous, inherently. Understanding inherent safety-related risks permit a team to design out or mitigate those risks. Hazard analysis is the systematic process identify and control safety risks.

I define a reliability failure as something that costs your organization money. It might be a warranty expense or a lost customer. A failure may also create customer expenses, too. Let’s talk about the range of un-reliability costs and their impacts.

The ability to determine a root cause of a failure is a skill. It requires agility, leadership, inquisitiveness, diligence, and technical skill. Successful RCA taps into your creativity and technical prowess. Using a structured approach helps.

Monitoring reliability performance requires both measurement and reporting skills. Focusing on making decisions we can tailor our metrics to improve our reliability program today. The right measures allow your team to spot problems and solve them.

The new CRE body of knowledge goes into effect January 2018. With the additions, deletions and changes to topics, it attempts to reflect what reliability engineering do on a daily basis. Let’s take a close look at the new 2018 BOK and what it means. [Read more…]
A tool is only as useful as knowing when and how to use it. In this webinar we will discuss how to identify an appropriate DOE project, and how to set up (define) a DOE. A process for DOE execution will be provided and discussed. We will also provide the thought processes needed to know when a DOE application is present. [Read more…]
Risk is borne from uncertainty. The reliability performance of your product line and of individual products is fraught with uncertainty. Identifying and understanding the types of risks involved helps your team mitigate reliability performance risk.
An obvious risk and common question when developing a new product involves the field failure rate. If the failure rate is too high, it may dissuade customers from buying the product. If too low, we set assign funds unnecessarily to cover unrealized warranty expenses. [Read more…]
