What is the BEST way to demonstrate alignment of IT projects with long-term business objectives?

Service level agreements (SLAs) define performance metrics for IT services but do not inherently demonstrate the strategic alignment of projects with long-term business objectives.

Portfolio management helps in prioritizing and managing a collection of projects, but EA provides the foundational strategic context and visualization of how those projects align to the overall business.

Enterprise Architecture (EA) is the best way to demonstrate alignment because it provides a holistic and structured framework that maps business strategy, processes, and objectives to IT systems and projects, ensuring that IT investments support long-term organizational goals. EA acts as a blueprint, showing how IT components fit together to achieve strategic outcomes.

Business impact analysis (BIA) assesses the potential effects of disruptions on business processes, which is crucial for recovery, but it doesn't primarily demonstrate alignment of projects with long-term business objectives.
