Value Stream Mapping is a visual tool used to analyze the flow of materials and information required to deliver a product or service from the beginning of the process to the customer. It is used to identify and eliminate waste and non-value added activities from the production process, and is a key part of Lean Manufacturing. Value Stream Mapping can also provide a clear picture of the current process, and can be used to develop and implement improvements that will reduce lead times and cycle times, and increase customer satisfaction.
