This Process Cartoon Value stream map depicts the flow of materials and information from supplier to customer. Value stream mapping shows a lean manufacturing technique for analyzing, designing, and managing the flow of materials and knowledge necessary to deliver a product to a customer. The first step in this value stream mapping is to create a current state map. This map can help you identify delays, restrictions, inefficiencies, and excess inventory. These are then removed from the ideal state map, which provides the organization with a lean efficiency strategy. This Value stream map is most commonly used in lean manufacturing. Still, they also determine the value stream—the sequence of activities required to design, manufacture, or provide goods and services to customers.
