Strategic Portfolio Management (SPM) and Enterprise Architecture (EA) integrate closely to align business strategy with the landscape of Business Applications and Application Services. SPM uses EA data, such as application cost, lifecycle, and technical and business fit, to inform investment decisions and prioritize initiatives in projects and portfolios. Conversely, EA benefits from SPM by tying application assessments to strategic goals, ensuring application rationalization and modernization efforts are business-driven. This integration enhances visibility and governance across both business capabilities and technology components.

Strategic Portfolio Management (SPM) and IT Service Management (ITSM) connect by aligning strategic initiatives with operational service delivery. SPM leverages ITSM data, such as incident trends, change volumes, and service performance, to prioritize and fund demands and projects that improve service quality and efficiency. ITSM benefits from SPM by gaining visibility into upcoming strategic changes, enabling proactive service planning and impact analysis. This synergy ensures that IT services evolve with business objectives and strategic priorities.

IT Service Management (ITSM) and IT Operations Management (ITOM) integrate to ensure seamless service delivery through proactive infrastructure monitoring and responsive support. ITOM provides ITSM with real-time visibility into the health, availability, and performance of services and infrastructure components via discovery, event management, and CMDB enrichment. In return, ITSM enables incident, problem, and change workflows that respond to and remediate ITOM-detected issues. They create a closed-loop system that improves service reliability, reduces downtime, and supports root cause analysis.

IT Operations Management (ITOM) and IT Asset Management (ITAM) integrate to deliver end-to-end visibility and control over Configuration Items and IT assets throughout their lifecycle. ITOM, through discovery and service mapping, feeds accurate and real-time configuration data into ITAM, ensuring the asset repository reflects the actual state of the infrastructure. In return, ITAM provides ITOM with critical asset details such as ownership, lifecycle status, finance-related information, and contractual obligations to support operational decisions and compliance. This integration enhances governance, optimizes asset utilization, and reduces risks related to shadow IT and untracked assets.

IT Asset Management (ITAM) and Enterprise Architecture (EA) integrate to ensure that technology assets align with architectural standards and strategic business goals. ITAM provides EA with detailed, accurate data on hardware and software assets, including lifecycle status, usage, and cost, enabling architects to make informed decisions about technology standardization and rationalization. In return, EA defines the target architecture and approved technologies, guiding ITAM in procurement, compliance, and decommissioning processes. This collaboration improves technology governance, reduces redundancy, and supports strategic planning across the IT landscape.
