This paper work presents a model of implementation of lean manufacturing for improving productivity and quality, by conducting a case study in a small scale industry at Ranchi, Jharkhand. The purposes of this paper are to identify waste related problems, cause of equipment failure, bottleneck problems and rectify them. The above problems are analyzed in concern with rejection control, inventory control, waiting time, set time and eliminating non value added time / activities. The complete problem is identified and depicted by value stream mapping. This paper conclude with discussing improvements and it proposes Value stream mapping lean tools can be applied in small scale industries and calculation of takt time for reduction of wastage and increasing productivity
