Use the Lean Metrics Comparison form to compare the baseline process to the improved process.
The Lean Metrics Comparison answers the following questions.
  • What is the total value added for the baseline process?
  • What is the total value added for the improved process?
  • What steps in the process add value and what steps do not add value?
  • Were steps that did not add value in the baseline process eliminated or modified in the improved process?

How-to

Choose all steps from the process maps or equivalent portions of the two processes. Otherwise, the comparison will be biased by the use of incomplete and potentially unbalanced data.

  1. You must have a process map with lean data (Cycle Time, VA, BVA, NVA) for each step in the baseline process.
  2. You must have a second process map with lean data (Cycle Time, VA, BVA, NVA) for each step in the improved process.
  3. In the Baseline (As-Is) Process table, choose the baseline map, then choose the shape data to add. In most cases, all shapes contribute to the total percentages of value added and non-value added.
  4. In the Final Improved Process table, choose the final map, then choose the shape data to add. In most cases, all shapes contribute to the total percentages of value added and non-value added.
