Lean Metrics Comparison

Use the Lean Metrics Comparison form to compare the baseline process to the improved process. Because you can use a process map to focus on cycle times and to identify waste, it is a key tool in many lean projects.

Answers the questions:
  • What is the total value-add for the baseline process?
  • What is the total value-add for the improved process?
  • What steps in the process add value and what steps do not add value?
  • Were non-value-add steps in the baseline process eliminated or modified in the improved process?
When to Use Purpose
End of project Document the effects of changes to the process on the percentage value-add and percentage non-value-add.

Data

This form has no data requirements because you use it only to display data collected elsewhere.

Guidelines

You should select 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.

How-to

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