Case Study
Health System Interface Modernization
Large health system aligning 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.
Context
Large health system aligning legacy lab and order interfaces with a more modern interoperability roadmap across inpatient and ambulatory workflows.
Problem
Site-specific mapping conventions and uneven launch criteria were creating rework, slowing decisions, and reducing confidence in readiness reviews.
Constraints
- 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
Standardized mapping expectations, readiness checkpoints, and launch evidence so teams could make cleaner go or no-go decisions across multiple workstreams.
Execution
- 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.
Outcome
- Gave teams one readiness model across multiple workstreams instead of site-by-site launch decisions.
- Reduced avoidable rework by clarifying mapping expectations and launch evidence earlier in the implementation cycle.
- Improved confidence in go or no-go decisions for interoperability releases with multiple owners.
Why It Matters
Shows the ability to turn complex EMR connectivity work into a repeatable operating model that can scale beyond a single project.
