Explanation
The business case is not an input to the task of prioritizing requirements, but an output of the enterprise analysis knowledge area. The business case is a document that presents the rationale and justification for initiating a project or a solution. The business case includes the description of the business problem or opportunity, the analysis of the costs, benefits, risks, and feasibility of the proposed solution, and the recommendation for the best course of action. The other options are correct inputs to the task of prioritizing requirements, as they provide the information and guidance needed to determine the relative importance and urgency of the requirements. The risk analysis identifies and evaluates the potential threats and uncertainties that may affect the project's objectives, scope, schedule, cost, or quality. The business need defines the problem or opportunity that the project or the solution aims to resolve or exploit. The requirements management plan describes how the requirements will be elicited, analyzed, documented, validated, and controlled throughout the project. References:
