It is derived from the Toyota production system and its key thrust is to increase the value added work by eliminating waste and reducing incidental work. The term lean manufacturing is coined to represent half the human effort in the company, half the manufacturing space, half the investment in tools and half the engineering hours to develop a new product in half the time. These benefits can be achieved only if the concept is religiously followed in the organization. In simple lean is manufacturing without waste.


Objective of Lean


The basic objective of lean is to minimize the waste, and continuous improvement in every stage of product by utilizing minimum time and cost. Lean manufacturing focuses on reduction of all kind of waste to make continuous flow of the work, reduce the cycle time, reduce the transportation, eliminate the non value added process, reduce the motion of workers by providing proper location of tools and parts, minimize the transportation, maximize the utilization of machines and reduce the inventory in the production space.

Lean Manufacturing Concept
