Your Reliability Engineering Professional Development Site
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!

Once a product is launched, it’s time to understand its performance. The design is done, and 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.

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 its limitations.

We have data. Often, an abundance of data concerning equipment failures. Failures per month or MTBF-type measures do not reveal sufficient insights to understand the pattern of failures.

We often have more data than we can use. For time to failure, warranty claims, and related field data, we should take the time to learn what we can. Let’s explore organizing your field data and use basic techniques let the data speak.
