Business Case
A business case is a documented economic feasibility study that establishes the validity of the benefits of a selected component lacking sufficient definition and that is used as a basis for the authorization of further project management activities.
Explanation
The business case is a business document that provides the justification for undertaking a project. It presents the analysis of costs, benefits, risks, and alternatives that supports the decision to invest in the project. The business case is typically developed before the project is formally initiated and is an input to the Develop Project Charter process.
A comprehensive business case includes the business need or problem being addressed, the analysis of the situation (including root cause analysis), the recommended solution, an evaluation of alternatives considered, the expected costs and benefits (including financial metrics such as ROI, NPV, IRR, and payback period), risks and assumptions, success criteria, and the organizational strategy alignment.
The business case is owned by the project sponsor or the business, not the project manager. It remains relevant throughout the project and is periodically reviewed — particularly at phase gates — to confirm that the project still delivers value. If the business case is no longer valid (for example, due to market changes), the project may be cancelled. The business case is also referenced during project closure to assess whether the intended benefits are on track to be realized.

Exam Tip
