Value stream mapping f

  1. 1. VALUESTREAM MAPPINGWHAT IS VALUE STREAM MAPPING? DESCRIPTIONThe Value Stream Mapping method (VSM) is a visualization tool oriented to the Toyota version of LeanManufacturing (Toyota Production System). It helps to understand and streamline work processes by usingthe tools and techniques of Lean Manufacturing. The goal of VSM is to identify, to demonstrate and todecrease waste in the process. Waste is defined as any activity that does not add value to the final product.The word is often used to demonstrate and decrease the amount of "waste" in a manufacturing system.VSM can thus serve as a starting point to help management, engineers, production associates, schedulers,suppliers, and customers to recognize waste and identify its causes. As a result, Value Stream Mapping isprimarily a communication tool, but it can also be used as a strategic planning tool. And as a changemanagement tool.In order to do this, the Value Stream Mapping method visually maps the flow of materials and information.From the moment that the products are entering the back door as raw materials. Via all manufacturingprocess steps. Until the moment that the products leave the loading dock as finished products.Mapping out the activities in the manufacturing process with cycle times, down times, in-process inventory,material moves, information flows, helps to visualize the current state of the process activities and guidestowards the future desired state.The process usually includes mapping the "Current State" and the "Future State". These then serve as thefoundation for other Lean Manufacturing strategies.
  2. 2. HISTORY OF VALUE STREAM MAPPINGThe use of waste removal to achieve competitive advantage inside organizations, was pioneered in the1980s by Toyotas chief engineer, Taiichi Ohno, and sensei Shigeo Shingo and is oriented fundamentallytowards productivity rather than towards quality. The reason for this is thought to be that improvedproductivity leads to leaner operations which help to expose further waste and quality problems in thesystem. Thus the systematic attack on waste is also a systematic assault on the factors that are underlyingpoor quality. And on fundamental management problems. The seven commonly accepted wastes in theToyota production system were originally (reformulation by Jones between brackets): 1. Overproduction (faster than necessary pace). 2. Waiting. 3. Transport (conveyance). 4. Inappropriate processing. 5. Unnecessary inventory (excess inventory). 6. Unnecessary motion. 7. Defects (correction of mistakes).Peter Hines and Nick Rich have suggested the following tools (Article: "The seven value stream mappingtools" - International Journal of Operations & Production Management, Vol. 17, No. 1, 1997, pp. 46-64.).SEVEN VALUE STREAM MAPPING TOOLS 1.

I VSM havent found any information about how to map the value stream when the production isnt all done in one company. In my case, the original company starts to work on the product and because its the smaller one, the product is then transported to another company which has the needed equipment for the operation needed. Then the product is transported back to the original company. I would like to know how to map this flow. If you have any experience with some similar case or if you have any ideas concerning how to map this, I would be very grateful for them. Thanks for your comments!"Van The Idea "Basically VSM is done to map the set of operations, 9Hooijdonk - Th Behind Lean required for a product to launch from order to deliverye Netherlands VSM to the market, considering both value-added and non value added operations. This mapping method is often used in lean transformations to find and eliminate waste in the value stream. A lean transformation can be compared to a river stream, in which you want your boat (the product) to flow without getting stuck on rocks (problem causers). To ease the flow, the water level (stock level, lead time) could be increased; the boat will not get stuck. Though it would create a rough stream (high costs)

Better is to keep a minimum water level (lean) and to clear all the rocks (uncertainty, unreliability, scarcity and more) in the stream. VSM is used to constantly identify the rocks, clear them, and lower the water level again."Juan VSM Plan "I need to compare a VSM plan example.

What I wish to capture is the waste within the logistics support functions. For example good receipt into store and engine dispatch from store rather than the flow of material throughout the internal process. Any ideas in the right direction would be greatly appreciated."
