During sprint execution for a mobile app, a developer needs clarification on the acceptance criteria for a task. What should the project manager do to obtain the required information?

In an Agile environment, the Product Owner is the definitive source for requirements and acceptance criteria. They represent the voice of the customer and are responsible for maximizing the value of the product. Therefore, collaborating with the Product Owner directly ensures the developer receives accurate and timely clarification, maintaining sprint momentum. Asking the project sponsor is incorrect because sponsors typically focus on high-level strategic objectives and funding, not detailed acceptance criteria. Emailing the client directly is incorrect as the Product Owner is the designated liaison for requirements, and bypassing them can cause confusion or miscommunication. Requesting assistance from the development manager is incorrect because while they manage the development team, they are not the authority on product requirements or acceptance criteria.
