Your First 90 Days: What a First Line Software FHIR Engagement Delivers and How We Measure It
Organizations that engage First Line Software for FHIR implementation want to know what they are buying before they sign. A proposal is not the same as a clear picture of what the first 90 days looks like in practice—what gets delivered, what milestones are hit, what the internal team experiences, and what success actually looks like at the end of the initial phase. This article provides that picture. It is based on the structure of actual First Line Software FHIR engagements and is intended to give executive sponsors, CIOs, and implementation leads the specificity they need to evaluate whether First Line Software is the right partner.
What a 90-Day Engagement Covers
The first 90 days of a First Line Software FHIR engagement is designed to move an organization from readiness assessment to production go-live for a defined clinical use case, or to lay the architectural and clinical foundation for a broader program with a clear timeline for full deployment. The scope depends on the organization’s starting state, EHR environment, and use case priority. What does not vary is the structure.
Day 1–21: Discovery and Architecture
The first three weeks are the most important of the engagement. Discovery and architecture determine every downstream decision. First Line Software assigns a clinical informaticist and a lead integration engineer to every engagement from Day 1. Both are senior—typically with 5 to 10 years of FHIR implementation experience—and both are active in the discovery phase, not observers.
- Week 1: EHR API assessment. First Line Software tests your EHR FHIR API against the use case scope, documents the CapabilityStatement, and identifies configuration gaps requiring EHR vendor engagement. The output is an EHR API readiness report with specific findings and remediation requirements.
- Week 1–2: Clinical workflow discovery. Working sessions with clinical stakeholders identify the current workflow, the specific data requirements, the workflow integration points where FHIR data needs to surface, and the acceptance criteria the clinical team will use to validate the implementation.
- Week 2–3: Data quality baseline. First Line Software assesses the data quality of source systems for the resource types in scope, documenting completeness rates, coding accuracy, identifier integrity, and duplicate patient risk. The output is a data quality baseline report with pre-build remediation priorities.
- Week 3: Architecture design. The integration topology, FHIR server configuration, resource profile structure, and terminology service requirements are documented and reviewed with the internal technical team. The output is an architecture decision record that becomes the reference document for the build phase.
Deliverables at Day 21: EHR API Readiness Report, Clinical Workflow Map, Data Quality Baseline Report, Architecture Decision Record.
Day 22–70: Integration Build and Validation
The build phase proceeds incrementally, with data quality validation embedded at each resource type milestone. The clinical informaticist and integration engineer work jointly throughout—validation is not a testing gate at the end of the build, it is continuous.
- Week 4–6: Core resource integration build. The resource types that the clinical use case depends on most are built first. Clinical acceptance testing for each resource type is conducted before the next resource type is built.
- Week 7–9: Full use case integration. All resource types in the use case scope are built and clinically validated. Information blocking compliance review is completed for the access patterns created by the integration. Monitoring dashboards are configured and deployed in the test environment.
- Week 10: Go-live readiness assessment. First Line Software assesses all five go-live confidence criteria and produces a go-live readiness report. Any unmet criteria are documented with remediation plans and revised timelines.
Deliverables at Day 70: Resource Integration Build (all use case scope resources), Clinical Acceptance Testing Report, Information Blocking Compliance Review, Go-Live Readiness Report, Monitoring Dashboard (test environment).
Day 71–90: Go-Live and Stabilization
Go-live in a First Line Software engagement is staged and monitored. The engagement does not end at the go-live cutover—it continues through the initial stabilization period with active support from the same team that built the system.
- Week 11: Staged go-live. Production deployment begins with a defined pilot cohort. Clinical champions are active. Monitoring dashboards are deployed in production. First Line Software maintains an on-call support arrangement for the first week of production.
- Week 12: First stabilization review. Data quality, clinical utilization, and system stability are reviewed at Day 7 post-go-live. Any issues identified are triaged and resolved within the engagement scope.
- Day 90 review: The formal 90-day engagement review covers all five go-live confidence criteria against production data, clinical adoption metrics for the pilot cohort, outstanding issues and resolution timelines, and recommendations for Phase 2 scope.
Deliverables at Day 90: Production Go-Live (use case scope), Day 7 Stabilization Report, 90-Day Engagement Review, Phase 2 Recommendations.
Stakeholder Confidence Checkpoints
| Checkpoint | Timing | Audience | Purpose |
| Discovery kickoff | Day 1 | CIO, CMIO, internal team | Align on scope, timeline, and communication cadence |
| Discovery findings briefing | Day 21 | CIO, CMIO, exec sponsor | Present EHR API findings, data quality baseline, architecture approach |
| Mid-build clinical review | Day 45 | CMIO, clinical champion | Clinical validation of first resource types; early issue identification |
| Go-live readiness briefing | Day 70 | CIO, CMIO, exec sponsor | Present go-live readiness assessment; confirm go-live decision |
| Post-go-live status | Day 7 post-go-live | CIO, CMIO | Production stability, early clinical utilization, outstanding issues |
| 90-day review | Day 90 | Exec sponsor, CIO, CMIO | Outcomes vs. objectives; Phase 2 planning |
How First Line Software Measures Success
First Line Software defines success against the criteria established in the discovery phase, not against generic implementation benchmarks. Every engagement begins with a success definition workshop that produces a written set of clinical and technical success criteria agreed upon by Clinovera and the client. The 90-day review measures outcomes against those criteria.
Typical success criteria for a 90-day FHIR engagement include: go-live confidence criteria met before production deployment, clinical adoption rate among the pilot cohort at 30 days, data quality benchmarks met for each resource type in scope, compliance deadline met or exceeded, and internal team capable of operating and monitoring the system without daily First Line Software support.
What the Internal Team Experiences
First Line Software engages the internal team as active participants, not observers. The integration engineers and clinical informatics staff at your organization are involved in discovery sessions, architecture reviews, clinical acceptance testing, and go-live operations. This is deliberate: knowledge transfer is more effective through active participation than through documentation handoff at engagement end.
At the end of 90 days, the internal team should be able to explain the architecture, operate the monitoring dashboards, triage data quality issues, escalate EHR API problems using the established vendor escalation path, and support expansion of the FHIR use case set without starting from zero.
Starting an Engagement
The first step is a 90-minute discovery conversation with First Line Software’s clinical informatics and integration engineering leadership. The conversation covers your EHR environment, use case priority, compliance timeline, internal team capability, and organizational constraints. Based on that conversation, Clinovera produces a scoping proposal within 5 business days.
Contact First Line Software to schedule your discovery conversation and begin the engagement scoping process.
