Our custom integration development for Seattle builds reliable, maintainable connections between enterprise systems with proper error handling and monitoring.
Phase 1 — Discovery and Design (2-3 weeks): understanding the integration requirements: system assessment (evaluating each system's integration capabilities — available APIs, data formats, authentication methods, rate limits, and known limitations — for Seattle: system assessment often reveals that systems have more integration capabilities than currently used — a hospital running Epic may have FHIR APIs enabled but not configured, or a manufacturer's SAP instance may have unused IDOCs that could support automated data exchange), data flow mapping (documenting every data flow required — source system, destination system, data elements, transformation rules, frequency, volume, and error handling requirements — for Seattle: data flow mapping quantifies the integration — a healthcare integration between Epic and a lab system may involve 15+ data flows for orders, results, specimen tracking, and billing), and architecture design (designing the integration architecture — choosing between: point-to-point (direct connections between systems — simple but creates a web of connections as system count grows), hub-and-spoke (centralized integration platform that all systems connect through — adds overhead but simplifies management), and event-driven (systems publish and subscribe to events — loosely coupled and scalable) — for Seattle: we recommend event-driven architecture for new integrations and hub-and-spoke for legacy system connections that require message transformation)).
Phase 2 — Development (4-10 weeks): building the integrations: connector development (building the connection to each system — API clients for modern systems, HL7/FHIR adapters for healthcare systems, EDI translators for legacy B2B exchange, database connectors for systems without APIs, and file-based connectors for systems that only support file transfer — for Seattle: connector development must handle the authentication complexity of enterprise systems — SAML, OAuth 2.
0, certificate-based authentication, and custom token schemes), transformation logic (building the data transformation layer — field mapping (matching source fields to destination fields), code translation (converting between system-specific code sets — diagnosis codes, product codes, status codes), data enrichment (adding information during transformation — looking up related data, calculating derived values), and format conversion (XML to JSON, HL7v2 to FHIR, EDI to structured data) — for Seattle: transformation logic is the most maintenance-intensive part of integration — every time either system changes its data model, the transformation must be updated), error handling (building robust error handling — validation (catching data quality issues before they propagate to downstream systems), retry logic (automatic retries for transient failures with exponential backoff), dead letter handling (capturing messages that can't be processed for manual investigation), alerting (notifying operations teams of integration failures with enough context to diagnose quickly), and compensation (undoing partial transactions when a multi-step integration fails partway through) — for Seattle: error handling is critical for healthcare integrations where a failed lab result delivery could delay diagnosis — errors must be detected and resolved within minutes, not days), and testing (comprehensive integration testing — unit tests (individual transformation logic), integration tests (end-to-end data flow through connected systems), volume tests (verifying the integration handles production data volumes without performance degradation), failure tests (verifying error handling works correctly — disconnecting systems, introducing malformed data, exceeding rate limits), and compliance tests (verifying healthcare, aerospace, or financial compliance requirements are met))).
Phase 3 — Deployment and Operations (2-3 weeks, then ongoing): launching the integration and maintaining reliable operation: deployment (deploying integrations with: parallel running (running new integrations alongside existing processes to verify correctness), gradual cutover (transitioning from manual/batch processes to automated integration incrementally), and rollback capability (ability to revert to the previous integration method if issues arise)), monitoring (comprehensive integration monitoring — data flow dashboards (volume, latency, error rate for each integration), SLA tracking (measuring whether integrations meet their delivery time and accuracy SLAs), anomaly detection (alerting on unusual patterns — sudden drops in volume, latency spikes, error rate increases), and reconciliation (periodic verification that data is consistent across integrated systems — catching any discrepancies that individual transaction monitoring might miss)), and maintenance (ongoing integration maintenance — API version updates (updating connectors when systems release new API versions), schema changes (updating transformations when source or destination data models change), performance optimization (tuning integrations as data volumes grow), and new integration development (extending the integration platform as new systems are added or new data flows are required))).
