When is MTBF Right?

MTBF has gotten a bad reputation. Is it deserved?

This 2-hour webinar, which costs $200, first looks at what causes failures in general and what mathematics govern all failure types. Then Mean Time To Failure (MTTF) is shown as a very general property of any (non-repairable) part or component, independent of its failure type or failure distribution. MTTF sometimes provides useful information and sometimes it is deceptive. An example of a deceptive MTTF is illustrated by an X-Ray tube whose failures are Exponentially distributed. Delving into detail, the Exponential distribution is seen to also have its useful points.

Next the distinction between Repairable and Non-Repairable products is explored, noting how that changes the relevant metrics and introduces some new cautions. Then Mean Time Between Failures is displayed, warts and all. Examples of using it correctly and some examples where one can get into trouble are illustrated. The X-Ray tube is revisited with a different underlying distribution to introduce the Weibull Distribution. The Weibull Distribution is presented as the Crown Jewel of Reliability Engineering because of its ability to accurately direct improvement efforts.

This webinar has some unavoidable mathematics, but much of it is presented as “nerd fodder” and can be bypassed for those not inclined to snuffle in the details.
