Putting Reliability Plans Together

Abstract

Chris and Fred discuss how we create a ‘reliability plan.’ It is not simply a list of tools …

Key Points

Join Chris and Fred as they discuss how you go about (at least philosophically) creating a reliability plan. People often start by looking at tools … which is where things get tricky.

Topics include:

• What are you trying to build? Think of a woodworker. Before they start looking for tools, they work out what they are building. Is it a cabinet? … a kitchen bench? … a roof? … a deck? All involve wood – but they are very different things. And they require very different tools. Reliability engineering is like woodworking. What are you trying to build?
• … and sometimes what are you trying to find? Do you need a rough guess or a detailed estimate of reliability? Depending on the answer to this question, you will use different tools. So for lower-level discussions like this, work out the DECISION that your reliability engineering effort is going to inform. Then work out what you need to do.
• And your favorite tool should never become ‘the plan.’ Is your organization really good (or at least comfortable) with FMEAs? … HALT? … fault trees? Sometimes we then try and use our favorite tool all the time. This is also not a plan.
• Plans need communication. Otherwise everything is effort without outcomes. You can’t just say ‘do HALT.’ You need to train and communicate why HALT is good. You can’t just go and ‘do HALT.’ You need to work out what the test results mean and communicate this to the designers and manufacturers who matter. You can’t just say ‘do HALT’ to these people and not take the results seriously.

Enjoy an episode of Speaking of Reliability. Where you can join friends as they discuss reliability topics. Join us as we discuss topics ranging from design for reliability techniques to field data analysis approaches.
