Add up the whole job at the same quality: preparation, review, correction and waiting. The first step getting faster doesn’t tell you what was saved.
Preparation is faster, so isn’t that time saved?
Only if review and correction didn’t grow.
A fictional comparison: 45 minutes faster is not 45 minutes saved.
The same batch, in minutes, at the same assumed quality:
- Preparation
- 60 before, 15 assisted.
- Review
- 20 before, 35 assisted.
- Corrections
- 10 before, 20 assisted.
- Total effort
- 90 before, 70 assisted.
- Result
- Preparation falls by 45 minutes. Total effort falls by 20, before setup and upkeep.
1. If review rises, find out why.
Is the output wrong, unclear or harder to trace? Each of those has a different fix.
Practical check: Compare the same task and standard, over enough varied cases to expose the weak spots.
2. Look at what finance would notice.
Quality. Track errors, missed exceptions and unsupported explanations.
Rework. Count reopened items and late adjustments, including work done by the people receiving the output.
Capacity. Staff time released is not automatically a cash reduction. Include setup, training, licences, usage and maintenance.
Practical check: Don’t declare success because more transactions went through a tool.
