According to me lean is initially applied to inventory by MIT team. Then extended to all resources. Then they first extended idea to waste. Basically lean initially is only part of industrial engineering. In a clever way, thelean proponents went extending lean concept to include all the objectives of industrial engineering but they could not accept all the techniques and tools of IE. Hence, the effectiveness of lean is not up to the expectations and sufficient criticism of Lean has surfaced. Now Even Jim Womack accepts that lean is not encountering problems in giving expected results.
But, readers have to learn the recommended lean implementation procedures as lean has value as one of the tasks of industrial engineering. It is certainly an advance in IE based productivity improvement.
