Value stream map

Definition

A value stream map is a visual tool used to analyze and design the flow of materials and information in a process. It helps identify value-added and non-value-added activities, facilitating process improvement by providing a clear overview of how work is done. This mapping technique is crucial for understanding the efficiency of systems and identifying areas for optimization.
