Product-system design
Connected billing, access, rewards, competitions, and future commitments as one subscription system.
Designing a subscription promise that stays coherent across billing, lifecycle states, entitlements, rewards, competitions, and Back Office operations.
Overview
The work connected the customer promise to the rules and operational controls required to keep it consistent over time.
Entitlement clarity
Made the distinction between fixed benefits, current estimates, lifecycle states, and allocation rules explicit.
Operational buildability
Linked customer-facing behavior with Back Office control and delivery-ready decision areas.
Subscription work in delivery
A development board showing subscription-related work moving through implementation. It demonstrates delivery context, not authorship of every visible item.
Main Challenge
An ongoing promise
A subscription must remain understandable after purchase, not only during checkout.
Connected states
Billing, access, rewards, tickets, and future commitments can change at different times.
Operational consistency
Customer behavior and Back Office controls need to follow the same product rules.
Featured Decisions
Fixed Auto-Entry Entitlement + Dynamic Current € Estimate
Keep the promised ticket entitlement stable while presenting its current estimated euro value as changeable context.
ContributionClarified the customer promise and its changing estimate
Auto-Entry Capacity, Allocation, and Carry Logic
Make limited competition capacity and the handling of subscription entitlements explicit.
ContributionStructured allocation and carry decision areas
Immutable Offer Version + Unfavorable-Change Notice Period
Preserve the offer a subscriber accepted and make unfavorable future changes explicit.
ContributionDefined offer-version and change-management principles
Supporting Decisions
Payment Retry and Semi-Active Lifecycle Behavior
Keep temporary payment disruption distinct from a fully ended subscription.
Annual ↔ Monthly Plan-Change Rules
Treat billing-cycle changes as lifecycle transitions with timing implications.
Coming Soon vs Auto-Entry Reservation Behavior
Separate product discovery from a confirmed entitlement reservation.
Selected Evidence
Subscription Lifecycle
State and transition evidence for the ongoing subscription relationship.
Operational Auto-Entry Control
Back Office evidence for managing the system behind the promise.
