3 Introduction to the Lean Manufacturing Lean manufacturing is the production of goods using less of everything compared to mass production: less waste, less human effort, less manufacturing space, less investment in tools, and less engineering time to develop a new product. It is renowned for its focus on reduction of the original Toyota Production System (TPS) “seven wastes” in order to improve overall customer value

4 Value Stream Mapping Value Stream Mapping is a Lean technique used to analyze the flow of materials and information currently required to bring a product or service to a consumer.

6 Implementation of VSM Identify the target product, product family, or service. Draw a current state value stream map, which is the current steps, delays, and information flows required to deliver the target product or service. This may be a production flow (raw materials to consumer) or a design flow (concept to launch). Assess the current state value stream map in terms of creating flow by eliminating waste. Draw a future state value stream map. Implement the future state.

7 Value stream mapping software Typically, the software is available as either enhancements to already available programs such as Microsoft Excel, Microsoft Visio, or stand alone. Utilizing software can help speed up the process and help simplify calculations that help make up a completed map
