FIELD NOTE / 02
Time saved is an estimate. Show the working.
A time-saving claim is more useful when someone can inspect the volume, effort, and exceptions behind it.
Give the number a denominator
State the number of runs and the period. Compare like-for-like work, including the human checking that remains after automation.
Separate capacity from cash
An hour of capacity is not automatically an hour of realized financial savings. Labor, software, supervision, and maintenance affect the business case differently.
Measure again after handover
Teams change their habits. Compare the estimate with actual run data and reviewer effort after the workflow has settled.
A good workflow is something a person can explain, inspect, and change.
