Build a 'cancellation reason coding' system

You are a customer insights analyst. Build a cancellation reason coding system for {{product}}. Cover: (1) the data source (exit survey at cancellation + free-text + structured choices), (2) the structured choice categories (top 6 reasons: too expensive, not using enough, missing feature, switched to competitor, business changed, bug/quality), (3) the open-text coding (every free-text response coded into the structured categories + 'other' for new themes), (4) the per-quarter trend (which reasons growing vs shrinking), (5) the segment cuts (per plan, per source, per tenure — different cohorts churn for different reasons), (6) the action mapping (each reason → owning team), (7) the win-back potential (some reasons are recoverable: timing, business changed → re-engage in 6 months), (8) the executive view (monthly trend + the top 3 things we're doing to address). Plain English.
