Checklist
Competing risks checklist for churn analysis
Seven steps to stop a blended churn rate overstating cancellations
A seven-step checklist for analysing churn when accounts can leave in more than one way. It covers listing exit types, recording each exit from interviews rather than inference, plotting cumulative incidence per type, the sum check against all-cause attrition, and re-checking churn risk models. Use it when you build or audit a retention dashboard. Koji runs exit interviews with every departing account, with a structured exit-type question that fills the missing field.
Where this appears
What's in this checklist
- List every way an account can leave your book
- Add an exit-type field to the churn table, filled from interviews
- Plot cumulative incidence per exit type, not one minus Kaplan-Meier
- Check the per-type curves do not add up to more than total attrition
- Label whether a chart shows cause-specific hazard or cumulative incidence
- Re-check any churn risk model whose target had no exit type
- Re-run the exit classification every quarter
