You get what you measure.  And if your measurements are wrong or incomplete, your chances of success are greatly diminished.  That’s where Total Process Efficiency (TPE) comes in.  It is a comprehensive set of metrics for measuring the efficiency of a resource.  TPE is “airtight”, meaning there is no ambiguity in the measurements and no potential losses that wouldn’t be caught.

While the metric has been most frequently used in equipment maintenance circles, it can be applied to other areas such as cell efficiency or people’s work.
