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.
You must have a process map
with lean data (Cycle Time, VA, BVA, NVA) for each step in the baseline
process.
You must have a second
process map with lean data (Cycle Time, VA, BVA, NVA) 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, all shapes contribute to the total percentages of value added and
non-value added.
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.
