When a Development Team is unclear about a functional requirement, what should they do?

The correct approach when the Development Team is unclear about a functional requirement is to collaborate with the Product Owner to clarify those requirements. The Product Owner is responsible for managing the Product Backlog and ensuring that the team fully understands the items in it. By engaging with the Product Owner, the Development Team can seek clarification on the requirement, ask specific questions, and gather necessary details that will guide their work. This collaboration is essential in Scrum, where communication between the Product Owner and the Development Team is key to delivering valuable increments of the product that meet stakeholder needs.

The other options would not contribute effectively to understanding the requirement. Continuing to work independently may lead to misunderstandings or assumptions that could result in misaligned product functionality. Asking other teams for insights, while potentially helpful in some contexts, may not guarantee clarity on the specific requirement, as those teams may not possess the necessary context about the product vision or user needs. Ignoring the requirement entirely would undermine the Scrum principle of delivering a potentially releasable product increment and could lead to incomplete or unsatisfactory outcomes for the stakeholders.
