Instrument before launch
Impact should be read off a dashboard, not reconstructed after the fact. Provenance is what makes a number unimpeachable in an executive room.
- Define success metrics with the data team before launch. Adoption, failed-search rate, missing-font events.
- Build the dashboards pre-launch so impact is read, not reconstructed.
- Tie each KPI back to the original business-case claim: drop-off pattern → search failure → adoption.
