A value‐stream map is a high‐level process map that captures the steps of a process from the time a customer orders a product to the time it is delivered. The map also shows how information, work, and materials flow through the process. The team starts with a current state map to document the process as it exists now. This map is used to identify and quantify waste and to highlight areas that can be improved.

After the current state is well understood, the team builds a future‐state map that eliminates unnecessary steps or other sources of waste that have been identified. This future‐state map gives the team a blueprint for improvement.
