What task is performed to ensure that all requirements align to the business need?
- A. Model Requirements
- B. Prioritize Requirements
- C. Define Requirements
- D. Validate Requirements
正解：D
解説：
The task performed to ensure that all requirements align with the business need is 'Validate Requirements'.
This process involves confirming that stakeholder, solution, and transition requirements are in line with the business requirements. It ensures that the designs satisfy the requirements and that both requirements and designs deliver business value and support the organization's goals and objectives. Validation is an ongoing activity that plays a crucial role in the business analysis process, as it helps to ensure that the project delivers the intended value and meets the needs it was designed to address.
References: The information about the validation of requirements aligning to business needs is supported by the Business Analysis Body of Knowledge (BABOK) and other educational materials provided by the International Institute of Business Analysis (IIBA), which emphasize the importance of this task in the business analysis process1.
