This document discusses value stream mapping (VSM), which is a lean manufacturing technique used to analyze and design work flows to create more value for the customer. VSM involves creating a current state map of the existing process flow, including value-added and non-value added activities. It then involves creating a future state map that improves the flow by reducing waste. Finally, an action plan is created to implement the changes needed to transition from the current to the future state. The goal of VSM is to maximize value and minimize waste in work processes.
