Diagram as Data

Once a process map exists as data, you can “re-lane” it without redrawing. This Lean value-stream lens replaces department swimlanes with VA/BVA/NVA and replaces phases with Doing/Waiting/Rework—creating a 3×3 grid of nine insights. It quickly surfaces bottlenecks, approval drag, and rework loops, and it’s easy to implement by adding two columns to your process table and regenerating the diagram.
