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?

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