If you are a reliability engineer – chances are you have done a Weibull plot. You take something like failure data, put it into a piece of software, and presto! [Read more…]
Having a reliability target for your product is great. But how does that help all the little design teams, who make their own decisions on all the different parts of your system?

What do you tell someone you just met when they ask, “So, what do you do?” Saying you’re a reliability engineer is likely to get a polite nod or confused look. How do you explain what you do, and why? Why is what we do as reliability minded folk important? [Read more…]
The reliability engineering discipline, like all fields of endeavor, is changing. The inclusion of risk management, the shift to proactively avoiding field failures, and the increasing use of sensors and models, all make the future fascinating.

The reliability culture of an organization is about how individuals make decisions. It is a combination of priorities & policies, behaviors & motivations, and information & capability. Understanding the current culture allows you to improve the culture.

When you ‘pass’ a standard based test, just what does that mean? How can you use test results in a meaningful way other than just noting the product ‘passed’? Understanding the failure mechanisms at play along with the statistics is key. [Read more…]
Graphics, when used well, can convey easy to understand information. Reliability graphics may focus on trends in failure rates or the verification of improvement work. Often reliability graphics convey time to failure patterns.

When a product or system fails there is a consequence. Often there is a loss of value. Each warranty replacement costs money. Downtime may result in lost revenue. Do you know the full extent of the costs involved when something fails?

When we make a measurement, we make a decision based on the data provided. It’s important to have data that is close enough to the actual measurement. If something is supposed to be 2 cm long and we measure it at 2.1 cm, what is the measurement error?

MTBF stands for ‘mean time between failure.’ This sounds intuitively easy to understand. But … if you haven’t taken the time to understand MTBF, and your organization relies on the reliability of its products, you are almost certainly in trouble. [Read more…]
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…]
