A project team delivers a solution based on the approved requirements and is confident that it meets the defined acceptance criteria. What should the business analyst do to obtain signoff?

The process for obtaining formal signoff should be defined in the project's planning documents. A RACI (Responsible, Accountable, Consulted, Informed) matrix is a standard tool used to clarify stakeholder roles and responsibilities. By referring to the RACI matrix, the business analyst can identify the individual(s) designated as 'Accountable' for accepting the solution, ensuring the correct person provides the official signoff.

A. The sponsor may be the accountable party, but this is not guaranteed. The RACI matrix provides the definitive answer without making assumptions.
B. The stakeholder who provided the most requirements is not necessarily the one with the authority to approve the final solution.
C. Formal signoff is a critical step in solution evaluation and project closure to confirm that the deliverables meet the agreed-upon criteria.

This section describes the use of a RACI chart to "identify the roles and responsibilities of the stakeholders in relation to the business analysis activities." The 'Accountable' role is typically the approver.
