What term describes the justification or reasons for a project proposal?

The term that best describes the justification or reasons for a project proposal is a business case. A business case outlines the rationale for initiating a project, including its benefits, costs, risks, and alignment with organizational strategy. It serves as a foundational document to help stakeholders understand the value of the project and make informed decisions about its approval and funding.

A feasibility study typically assesses the viability of a project and whether it can be accomplished within constraints such as time, budget, and technical capabilities, but it does not serve as the overarching justification for the project itself. A project charter provides a high-level overview of a project, including its objectives and scope, but it does not delve into the justification as thoroughly as a business case. A scope statement defines the specific boundaries and deliverables of the project, which is important for project planning but does not articulate the reasons for undertaking the project.
