The concept and use of lean thinking refers to the total enterprise and is aimed at adding
value to an organisation through the elimination of waste. The maintenance function is
expected to add value through its activities, requiring greater management integration
within the enterprise. However, despite some methodologies associated with lean thinking
being used by maintenance, evidence could not be found to support a generic structure for
lean activities. Furthermore, there is no evidence that suggests a suitable methodology that
can identify possible improvements for the maintenance function of lean thinking activities,
other than direct operational measures.
