Cohort Analysis for Pipeline

3 min read

Cohort analysis groups deals by a shared characteristic — usually creation date — and tracks their outcomes over time. Instead of looking at all deals in the pipeline simultaneously (which mixes deals from different time periods with different characteristics), cohort analysis lets you compare the January cohort against the February cohort against the March cohort. If the March cohort has a 20% lower conversion rate than January, something changed in March — and you know exactly when to look.
