While journeys are broken down by customer persona, the core of the role is technical: tracing how events, triggers, and data move between systems—CDP, CRM/ESP, loyalty, app, and POS—at each stage, building and QA'ing journeys within orchestration platforms, and ensuring tracking and tagging capture the right data throughout. Map end-to-end digital customer journeys as system and data-flow diagrams, tracing how events, triggers, and data move between platforms (CDP, CRM/ESP, loyalty, app, POS) at each stage.
