Real success is measured by business and customer outcomes, not by how faithfully a team performs ceremonies. The trap is measuring activity (standups held, velocity numbers) instead of value. Good measurement combines delivery performance, product impact, and team health.
What to measure
DELIVERY lead time, deployment frequency, change-fail rate,
time to restore (DORA metrics)
PRODUCT customer satisfaction, feature adoption, value delivered
TEAM HEALTH engagement, sustainable pace, psychological safety
Outcome metrics ("did users get value faster?") beat output metrics ("how many points?").
Concrete example
After an adoption, a team's lead time from idea to production drops from 6 weeks to 5 days and customer-reported defects fall. That is success — regardless of whether velocity went up.
