In the Requirements Analysis and Design Definition knowledge area, which of the following is included?

In the Requirements Analysis and Design Definition knowledge area, "Verify Requirements" is essential as it ensures that the requirements documented are accurate, complete, and aligned with stakeholder needs and project objectives. Verification is a critical step in the requirements management process, as it helps identify any discrepancies or unclear elements before moving onto subsequent phases of development. This process typically involves reviewing the requirements with stakeholders, validating them against business goals, and ensuring that they can be effectively delivered and implemented in the final solution.

The other activities listed, while important in the overall project lifecycle, fall outside the specific scope of the Requirements Analysis and Design Definition knowledge area. Conducting user research, for instance, typically occurs during the earlier phases of project initiation or requirements gathering. Implementing solutions is part of the development phase, where the actual build of the solution takes place. Testing solutions is an activity primarily associated with the quality assurance phase, aimed at ensuring that the implemented product meets the agreed-upon requirements and functions as intended.
