Case-study evidence worksheet. Measure the work people can complete as well as the effort changed. No Birkan results or example numbers are supplied.
Before and after the same task
- Team, task, task mix, and comparison scope:
- Baseline period and task count:
- Comparison period and task count:
- Earlier active human time per task, across all participating roles:
- Current active human time per task, including prompting, review, correction, and monitoring:
- Additional training/setup/maintenance effort and period:
- Elapsed waiting/decision time, measured separately:
- Method, records, sample size, and uncertainty:
What the team did with the capacity
- Work that previously waited or was not attempted:
- Specific additional work completed and by whom:
- Accepted output counts and evidence:
- Quality criteria, rework, and comparable denominators:
- Backlog before and after:
- New task independence or broader coverage, with examples:
- Outcome for colleagues, customers, or operations:
- What remains difficult:
Interpretation
- Other changes: staffing, demand, training, ERP fixes, process redesign:
- Supported conclusion and its limits:
- Evidence status: estimated / observed / attributed experience / measured / unresolved:
- Reviewer and date:
Estimated capacity released can use comparable task volume multiplied by the difference in total active human effort per task, less additional period-level overhead. Record assumptions and avoid double-counting effort. Released time, additional accepted output, monetary savings, and revenue are separate claims.
