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…]
One of the more significant challenges for reliability engineering in product development is complete execution of the planned reliability process in product development. The reliability tools and techniques outlined in the product plan are often skipped or delayed, minimizing the opportunity for outputs to impact the program and product fully. [Read more…]
A reasonable model helps you make informed decisions. In many cases, a simple reliability block diagram provides the insights your team needs to prioritize and achieve the desired reliability performance. Let’s create, populate and use RBDs effectively.
RBDs comprise of a few simple elements and arrangements, yet are capable of describing a wide range of products and systems. There are a few assumptions to keep in mind, and a few basic ways to create a useful model for your system. [Read more…]
Accelerated Life Testing, ALT, is a technique to estimate the time to failure pattern for an item. In short ALT allows us to shorten time. Done well it provides valuable insights into the future. Done poorly, it is a colossal waste of resources.
In this webinar, let’s talk about the various methods available to you for ALT. How to select the right approach given your specific understanding of the failure mechanism involved. And discuss best and a few worst practices when planning and conducing ALT. [Read more…]
