The correct answer is the sponsor because the sponsor is typically the individual or group who provides the financial resources and overall direction for a project. They hold the ultimate authority to make decisions regarding the project, including authorizing changes after deployment to enhance performance. The sponsor understands the strategic vision and objectives related to the project, which allows them to assess whether proposed changes align with business goals and whether additional investment is warranted.

The tester and operational support staff play crucial roles in ensuring the solution functions as intended and identifies areas for improvement, but they usually do not have decision-making authority over changes post-deployment. While the business analyst may gather requirements and communicate potential enhancements, they do not typically have the final say in authorizing changes, as that responsibility rests with the sponsor who is accountable for the project's success on a broader scale.
