Review, assess, and document interface specifications, integration requirements, system interactions, APIs, web services, file exchanges, interoperability solutions, source and target systems, integration patterns, message flows, data mappings, transformation requirements, validation rules, dependencies, operational ownership, and related technical artifacts to support architecture reviews, implementation planning, testing, deployment, operational readiness, governance, and knowledge transfer activities. Apply a reuse-first architecture approach by evaluating existing systems, shared services, enterprise capabilities, approved contracts, vendor-supported solutions, and reusable assets before recommending new approaches, while developing and promoting reusable architecture patterns, reference architectures, integration approaches, and technical frameworks for use across RHTP initiatives.
