Lean manufacturing is an operational strategy oriented towards achieving the shortest possible cycle time by eliminating wastes. 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.
This article highlights the Lean manufacturing;
which is a variation on the theme of efficiency based on optimizing flow; it is
a present-day instance of the recurring theme in human history towards
increasing efficiency, decreasing waste, and using empirical methods to decide
what matters, rather than uncritically accepting pre-existing ideas. It is an
article deals with the Lean manufacturing tools and techniques. The
implementing lean manufacturing in India and its benefits are discussed.
What Is Lean Manufacturing?
Lean manufacturing is a philosophy pioneered by Toyota Motors (and codified by James P. Womaks The Machine that Changed the World: The Story of Lean Production), based on the planned elimination of all waste, the continuous improvement of productivity, and an ongoing focus on customer value. It covers a wide variety of operations for reducing waste, increasing productivity and cutting cost. The emphasis in lean manufacturing is utilization of lesser resources to produce the same goods. Lean system basically aims at half the hours of engineering effort, half the product development time, half the investment in machinery, half the hours of human effort in the factory, half the factory space for the same output, half the defects in the finished product, increased capacity or throughput.
