description: The Mileva Method (CRISP) — Phase 5: Prove. Success validation against Phase R baseline metrics. Use after deployment. Triggers on "prove", "phase 5", "validate", "did it work", "success criteria", "measure results", or after go-live.
P — Prove: Success Validation
Did the needle move?
This phase closes the loop back to Phase R. One question drives everything.
What to Measure
Pull the baseline and targets from docs/success-metrics.md and measure against them:
- Quantitative: Did each metric hit its target? (e.g. "quotes sent in 4min vs 4h before")
- Qualitative: Re-run the survey or interview from the Phase R baseline frustration score — did it improve?
- Second-order effects: Did the downstream impacts materialise? (e.g. cart abandonment dropped after checkout speed improved)
Outcomes
Success → document what worked, close the project, capture learnings.
Partial → identify which metrics hit and which didn't. Was the target unrealistic, or did the solution miss?
Fail → return to Phase R. The problem may have been misdiagnosed, or the success criteria were wrong.
In Serbia, when things go sideways, we make jokes. It's not denial — it's perspective. Balkan humor is the ability to look at a disaster and find the absurdity before you find the culprit. Apply that here. If Phase P says fail, laugh once — then go back to Phase R with fresh eyes. A failed outcome is the most honest piece of data you'll collect in the whole project. The problem was misdiagnosed. Now you know exactly where. That's worth something.
