The Lean Production System (sometimes known as the Toyota Production System) is a well-established operating system based on the idea of relentlessly eliminating waste and non-value added activities from the production process. The manpower freed up from these non-valued added tasks is reassigned to other tasks that do add value for the customer. It is truly an operating system that impacts every aspect of the production and can truly be called a culture. There are many toolkits and techniques associated with Lean Production but mindset transformation is the key. There is only one way to run any process step: every employee uses this method and every employee is responsible for helping to improve his section of the plant – through Lean events and not as an individual. Heroics don’t factor into lean.
