What should a Development Team do when having trouble delivering a working increment due to unclear requirements?

When a Development Team encounters unclear requirements that hinder their ability to deliver a working increment, collaborating with the Product Owner to determine what is feasible is the most effective and proactive approach. The Product Owner is the key stakeholder responsible for the Product Backlog and has a deep understanding of customer needs and priorities. By engaging in collaborative discussions, the Development Team can clarify requirements, ask questions, and gain insights that help them refine the scope of work for the current Sprint. This interaction ensures that the team focuses on delivering the most valuable increment based on the users' needs and the overall goals of the product.

This approach fosters a collaborative environment, allowing for shared understanding and alignment on priorities, which are essential components of the Scrum framework. It also facilitates agility, enabling the team to adapt and respond to changing requirements and uncertainties more effectively.

The other options such as waiting until the next Sprint for clarification, consulting other teams without collaborating with the Product Owner, or adjusting the Definition of Done do not address the immediate need for clarity on requirements. These alternatives might lead to delays or misunderstandings, which can further impede progress and effectiveness in delivering a valuable product increment.
