ABSTRACT Today’s world, manufacturing industries are more competitive and increase the productivity with less cost. There are using certain principle to reduce the cost and wastage. Lean principle is the best method to reduce the wastage. Lean means reduce the waste. In this paper a reference is made in an automobile valve manufacturing industry. Cycle time and takt time are calculated for various processes. Value stream mapping is the main tool used to reduce the wastage. Current and future state value stream mapping illustrate before and after implementation of lean. The matlab simulation software is used
