Which of the following is NOT a responsibility of the business analyst in the Build phase?

In the context of the Build phase within a project, responsibilities are typically focused on ensuring that requirements are met and that the development team has the clarity needed to execute their tasks effectively.

Clarifying acceptance criteria on user stories is essential during this phase, as it helps the development team understand the criteria for success and ensures that the implementation will meet stakeholder expectations. This also directly impacts the quality assurance processes that will follow in future phases.

Capturing stakeholder feedback plays a crucial role because it allows the business analyst to gather insights on the development progress, ensuring that the solution aligns with stakeholder requirements. This is vital for identifying any adjustments needed before the final product is completed.

Answering developers' open questions is also key to facilitating communication between analysts and developers. This helps prevent misunderstandings and fosters a collaborative environment, ensuring that the development proceeds smoothly.

Conducting performance evaluations, however, is typically not a responsibility of the business analyst during the Build phase. This task generally falls to project managers or team leads, aligning more closely with performance measurement and resource management. Thus, this option correctly identifies a responsibility that is outside the typical scope for a business analyst in this specific phase.
