Many reliability engineering activities practised today cannot contribute to the objective of reliability engineering, which is the prevention of failure. Lean is a management philosophy with the objective of maximising value by removal of waste from all activities. Waste is defined as any non‐value added activity or process. Can lean be applied to reliability engineering?
This paper starts with a brief discussion on the essence and practice of both reliability engineering and lean. It provides a definition of value in the context of reliability engineering, and applies this definition to identify categories of reliability engineering activities which can be considered as waste. It is argued that lean can (and should) be used during the development of a Reliability Program Plan to select only value added activities for execution.
