We designed and implemented an enterprise integration platform over 22 weeks. Phase 1 (weeks 1-6): integration audit and architecture design. We mapped all 247 integrations, classifying each by business criticality, data sensitivity (personal data, financial data, health data), regulatory exposure, and technical health. 34 integrations were flagged for GDPR remediation. 23 integrations were identified as redundant (duplicate data flows that had accumulated over time). 12 critical integrations with no monitoring were prioritized for immediate stabilization. The target architecture used MuleSoft Anypoint Platform as the enterprise integration backbone, deployed on AWS Dublin (EU data residency), with event-driven architecture (Amazon EventBridge) for real-time data streaming alongside request-response API integrations. Phase 2 (weeks 4-12): GDPR compliance remediation.
For each of the 34 non-compliant integrations: documented the lawful basis for personal data transfer, implemented data minimization (removing unnecessary personal data fields from integration payloads -- 14 integrations were transferring 60-80% more personal data fields than the downstream system actually used), built deletion propagation (GDPR deletion requests cascade through all integrations holding that individual's data), and implemented consent synchronization (marketing consent status flows through all marketing technology integrations in real-time). A central integration registry documents every data flow: source system, destination system, data classification, lawful basis, retention policy, and responsible data owner. Phase 3 (weeks 8-16): core business automation. Revenue recognition automation: integrated Salesforce (CRM) with NetSuite (ERP) for automated revenue recognition across 16 European entities, handling multi-currency transactions (EUR, GBP, SEK, CHF, DKK, NOK, PLN), ASC 606 / IFRS 15 revenue allocation, intercompany transfers, and automated journal entries with approval workflows.
HR integration platform: connected Workday (core HR) with local payroll providers across 16 countries, benefits platforms, learning management, and performance management -- creating a single people data platform with country-specific workflow variations and GDPR-compliant cross-border data transfers (standard contractual clauses for non-EU entities). Marketing automation governance: integrated HubSpot, Salesforce, and data enrichment tools with GDPR consent management at the centre -- no marketing data flows to any system without verified consent, and consent changes propagate in under 5 seconds across all connected platforms. Phase 4 (weeks 14-22): monitoring, governance, and resilience. Integration monitoring dashboard: real-time visibility into all 247 integrations (now consolidated to 186 after redundancy elimination). Error rates, latency, throughput, and data quality metrics for every integration. Automated alerting for failures, anomalies, and SLA breaches. Integration governance framework: new integrations go through an approval process that assesses GDPR compliance, data classification, business justification, and technical architecture before deployment.
No more shadow IT integrations. Operational resilience: critical integrations (financial, regulatory) have automated failover, retry logic, dead letter queues for failed messages, and graceful degradation to manual fallback processes.
