Daniel Thomson developed comprehensive documentation and sequence diagrams for the Outreach Referral workflow in the tewhatuora/cinc-fhir-ig repository. Focusing on FHIR-based ServiceRequest and Task interactions, he modeled the creation, acceptance, cancellation, and completion flows, incorporating tagging and metadata to support update tracking. Using PlantUML and Markdown, Daniel iteratively refined the workflow context and use cases across multiple commits, ensuring clarity and maintainability for integration teams. His work established a single source of truth for onboarding and downstream development, providing detailed system design artifacts that facilitate governance and integration readiness without introducing new bugs or requiring immediate feature rework.
