Case Study

Health System Interface Modernization

A large health system needed product, clinical, implementation, and support teams to align legacy lab and order interfaces with a more modern interoperability roadmap across inpatient and ambulatory workflows.

Health system with inpatient and ambulatory workflows, multiple technical owners, and mixed legacy-to-modern interoperability priorities.

Product Context and Affected Users

A large health system needed product, clinical, implementation, and support teams to align legacy lab and order interfaces with a more modern interoperability roadmap across inpatient and ambulatory workflows.

Product Problem

Affected implementation and clinical users were navigating site-specific mapping conventions and uneven launch criteria. Product and delivery teams could not compare readiness consistently, which created rework and slowed decisions.

Constraints and Competing Priorities

  • Inpatient and ambulatory workflows needed to stay aligned without destabilizing existing production interface behavior.
  • Technical leads, QA, operations, and clinical stakeholders each controlled a different part of readiness evidence.
  • Legacy HL7 and interface-engine realities still had to work while the organization pushed toward more modern interoperability patterns.

Decision and Rejected Alternative

Standardized mapping expectations, readiness checkpoints, and launch evidence across workstreams. The rejected alternative was to preserve site-by-site criteria for maximum local flexibility; that would have continued inconsistent decisions and shifted avoidable complexity into QA and support.

Execution Model

  • Facilitated discovery workshops to align technical and clinical handoff expectations.
  • Standardized mapping requirements and acceptance criteria for HL7 v2 and FHIR-related workstreams.
  • Established recurring readiness reviews with shared risk ownership across product, engineering, QA, and operations.
  • Introduced a cutover checklist model that clarified dependencies before launch approval.

Specific Before and After

  • Before, each workstream assembled readiness evidence differently; after, teams reviewed the same mapping, dependency, and launch criteria.
  • Before, mapping ambiguity surfaced late in testing; after, expectations were resolved earlier through shared acceptance criteria.
  • Go or no-go discussions moved from competing status narratives to explicit evidence and named risk ownership.

Interoperability Product Relevance

Shows product leadership that converts recurring implementation variation into a reusable platform operating model without ignoring clinical workflow constraints.
