Write from the customer promise inward
Begin with what a reasonable customer will believe the offer means. Translate that promise into eligibility rules, decision states, timing, exception paths, and support responses.
Assign ownership across the lifecycle
Name owners for campaign setup, order data, qualification, customer messages, fulfillment coordination, returns, support, reconciliation, compliance review, and reporting.
Version the program before launch
Keep approved terms, campaign scope, rule definitions, templates, and reporting fields together under a version and effective period. Changes should be reviewable and traceable.
