Description

This curriculum spans the technical and organisational complexity of a multi-workshop integration redesign program, matching the depth of an internal capability build for enterprise process modernisation.

Module 1: Assessing Integration Requirements in Process Context

Identify which legacy systems must exchange data during redesigned process execution, based on current workflow logs and system dependency maps.
Document data ownership boundaries across departments to determine which team approves integration access and schema changes.
Map transaction volume and frequency between systems to assess whether batch or real-time integration is operationally feasible.
Evaluate whether integration points require human-in-the-loop validation or can be fully automated based on error tolerance in financial or compliance processes.
Determine if third-party APIs used in the process have rate limits or SLAs that constrain integration design options.
Classify data sensitivity at each integration touchpoint to enforce appropriate encryption and access logging requirements.

Module 2: Data Schema Alignment and Transformation Strategy

Resolve field-level discrepancies such as date formats, currency codes, or status enumerations between source and target systems using canonical data models.
Decide whether to embed transformation logic in middleware or delegate to source/target systems based on performance and maintainability trade-offs.
Implement field-level audit trails to track data origin and transformation history for compliance and debugging.
Select lookup mechanisms for reference data (e.g., customer IDs) when systems use different master data sources.
Handle missing or null fields in payloads by defining default values, fallback queries, or rejection rules based on business criticality.
Design error-handling routines for malformed data that preserve transaction state without blocking downstream process steps.

Module 3: Middleware Selection and Runtime Architecture

Choose between point-to-point connectors and enterprise service bus (ESB) based on the number of integrated systems and long-term scalability needs.
Deploy integration middleware in high-availability clusters when the process supports mission-critical operations like order fulfillment or patient intake.
Isolate integration components in DMZ networks when connecting on-premises systems to cloud applications to meet security policies.
Configure message queuing with dead-letter queues to manage transient failures without data loss during peak loads.
Size middleware resources based on historical throughput and projected growth to avoid latency bottlenecks in real-time processes.
Implement circuit breakers and retry throttling to prevent cascading failures when downstream systems become unresponsive.

Module 4: Orchestration of Cross-System Workflows

Define correlation IDs to track a single business transaction as it moves across multiple systems and integration hops.
Model compensating actions for long-running transactions that cannot use two-phase commit protocols across heterogeneous systems.
Sequence integration steps to respect business dependencies, such as ensuring inventory reservation occurs before payment capture.
Monitor end-to-end process latency to detect performance degradation originating in integration layers.
Use workflow timers to escalate or cancel processes when expected responses from external systems exceed defined thresholds.
Log intermediate payloads at key orchestration points to support audit reviews and incident root-cause analysis.

Module 5: Identity, Access, and Secure Data Exchange

Configure OAuth 2.0 client credentials or mutual TLS for system-to-system authentication based on target system capabilities.
Map service account permissions to the principle of least privilege, ensuring integrations access only required data fields.
Mask sensitive data in integration logs using dynamic obfuscation rules based on data classification tags.
Rotate API keys and certificates on a defined schedule and automate notification of upcoming expirations.
Implement payload encryption for data in transit when regulatory requirements mandate end-to-end protection.
Validate inbound messages for schema conformance and digital signatures to prevent injection or tampering attacks.

Module 6: Monitoring, Logging, and Incident Response

Define service-level objectives (SLOs) for integration uptime and latency, and configure alerts when thresholds are breached.
Aggregate logs from multiple integration components into a centralized observability platform for cross-system analysis.
Tag monitoring metrics by business process (e.g., onboarding, invoicing) to prioritize incident response based on impact.
Establish runbooks that specify escalation paths and recovery steps for common integration failure modes.
Conduct periodic failover tests to validate backup integration routes and data recovery procedures.
Track message delivery status to detect silent failures where data appears processed but was never received.

Module 7: Governance, Change Management, and Lifecycle Control

Enforce version control on integration artifacts and require peer review before deployment to production environments.
Coordinate integration changes with application release cycles to avoid mismatches in API contracts or data models.
Conduct impact assessments when retiring legacy systems to identify dependent integrations and migration requirements.
Document data lineage for regulatory audits, showing how information flows across systems via defined integration paths.
Establish a change advisory board (CAB) to approve high-risk integration modifications affecting multiple business units.
Archive deprecated integration configurations and redirect monitoring to new implementations without disrupting operations.
