Also known as: Investment Case
A structured justification that outlines benefits, costs, risks, and options to support an investment decision.
DESCRIPTION
A business case evaluates options to solve a problem or seize an opportunity, comparing costs, benefits, risks, and alignment with strategy. It informs governance bodies whether to proceed, defer, or stop an initiative. Effective cases include measurable outcomes, alternatives analysis, delivery roadmap, and assumptions. In data and AI, they address platform costs, talent, data readiness, and expected value from analytics or automation. Post-implementation reviews verify benefit realization and refine future cases.
