A project team new to agile is in progress. After the first sprint review, team performance declines because there is not an adequate flow of work. What should the project manager do?

The correct answer is to provide the product owner with training. In agile, the Product Owner is responsible for managing the Product Backlog, which includes ensuring it is refined, prioritized, and contains enough ready-to-work items to maintain a steady flow for the development team. A decline in team performance due to an inadequate flow of work directly indicates a deficiency in Product Backlog management, which is a core responsibility of the Product Owner. Training would equip the Product Owner with the necessary skills to effectively manage the backlog and ensure a continuous flow of value. Submitting a change request to rebaseline the project is incorrect because rebaselining is typically for significant scope, schedule, or cost changes, not for addressing operational workflow issues within an agile sprint. Changing the project approach to hybrid is premature and likely unnecessary; the issue stems from a specific role's execution within the current agile framework, not an inherent flaw in the framework itself. Discussing the issue with stakeholders is too broad and doesn't address the root cause or provide a solution; the specific role responsible for the work flow needs direct support.
