Start with the decision
Clarify whether the analysis supports approval, comparison, expansion, or remediation. The question determines the period and level of evidence required.
Establish a baseline
Use cycle time, staffing, error rate, infrastructure cost, conversion, downtime, or support volume. When data is incomplete, use a sample and state the limitation.
Include total cost
- Licensing, subscription, infrastructure, and equipment
- Implementation, integration, and migration
- Internal time and consulting
- Training and temporary productivity loss
- Security, monitoring, support, maintenance, and exit cost
Classify benefits
Separate direct savings, cost avoidance, released capacity, revenue, risk reduction, and strategic capability. Time saved is not automatically cash saved.
ROI = (net financial benefit − total cost) ÷ total cost × 100%
Use scenarios and sensitivity
Model conservative, base, and optimistic cases. Test the impact of slower adoption, higher integration cost, or delayed delivery.
Measure after launch
Review actual performance at defined checkpoints and connect financial results to operational and adoption indicators.
Measurement checklist
- Verified baseline
- Full one-time and recurring cost
- Benefit owner and data source
- Adoption assumption
- Conservative scenario
- Post-launch review dates
