Womack and Jones formalized LEAN and popularized it with the book “Lean Thinking”.
They outlined five principles :
To identify the value, you must think as the customer and ask the question?
The customer is not prepared to pay to offset the waste and inefficiency supplier.
It’s identifying value-added operations for the development of the product or service as expected by the customer. But it is also identify non value-added operations, ie waste.
Like a river, a workflow or administrative flow will flow more easily in a linear process where operations are connected without disruption and without interruptions.
We must produce goods or services if the customer has explicitly requested.
Once launched dynamic transformation, we must return to the cycle of continuous improvement to bring new ideas and remove new waste.
