1. INTRODUCTION 2.1. What is Value Stream Mapping (VSM)
Value Stream Mapping (VSM) is a visualization tool oriented to the Toyota version of Lean Manufacturing (Toyota Production System). It helps to understand and streamline work processes using the tools and techniques of Lean Manufacturing. The primary objective of VSM is to identify and demonstrate the flow of process to decrease a waste. VSM also can aid engineers, management, suppliers to recognize the waste and eliminate it. Waste is not value added for a company. It needs to be eliminated to reduce cost and improve the company business.
This VSM is primarily to eliminate the 7 waste that occurred in the company such as overproduction, waiting, transport, inappropriate processing, unnecessary inventory, unnecessary motion, and defects. As the focus of the value stream includes the complete value adding (and non-value adding) process, from conception of requirement back through to raw material source and back again to the consumer’s receipt of product, there is a clear need to extend this internal waste removal to the complete supply chain. This waste can be eliminated when the VSM is constructed. The VSM will have all details needed to overcome this waste. In addition, the Mapping contains the cycle time
