Ways to test a health score compared
Backtest, survey, CSM calls and AI interviews on what a CS Ops lead needs

A comparison of four ways to check a customer health score: a backtest on past renewals, an NPS or CSAT survey, calls run by the account owner, and AI-moderated interviews. The criteria are the ones a CS Ops lead weighs: the reason behind a miss, sample coverage, independence, consistency, time to read and effort. Koji is the highlighted column.
