Value Stream Mapping is a Lean technique used to analyse the flow of materials and information currently required to bring a product or service to a consumer.
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). There are 'standard' symbols for representing supply chain entities.
Assess the current state value stream map in terms of creating flow by eliminating waste.
