Architecture Patterns

Map of the seven architecture patterns over the customer data journey, in four stages plus a foundation band. First stage, identity: pattern 01, split profiles, on identity as a contract with the source. Second stage, profile and state, with two patterns: 02, one object for all, on separating operational state from customer state, and below it 03, writes that collide, on Profile writes as shared state. Third stage, decision: pattern 06, duplicated eligibility, on modeling Decisioning inputs by consumption. Fourth stage, activation: pattern 05, every channel from zero, on reusing the data foundation across channels. Below the four stages, a foundation band crossing all of them holds the two patterns that belong to no single stage: 04, temporary stays, on the exit path an MVP architecture needs, and 07, only you can run it, on handover as architecture. Each cell links to its page, and the full list with the long titles sits right below the map.
