What should a Scrum Master do in response to a Project Manager's concerns about productivity?

Sharing the current Product Backlog and projections is the most effective response for a Scrum Master addressing a Project Manager's concerns about productivity. The Product Backlog represents the prioritized work items that the Scrum Team has committed to, which provides transparency regarding what is being worked on and the estimated effort required to complete it. By presenting this information, the Scrum Master can help the Project Manager understand the team's workflow, how backlog items are progressing, and any potential impediments affecting productivity.

Additionally, projections provide insights into future work and help set realistic expectations for delivery. This transparent communication fosters a collaborative environment where the Project Manager can better comprehend the team dynamics and challenges, facilitating informed discussions about productivity without resorting to assumptions or generalizations. This approach not only addresses the Project Manager's concerns but also enhances trust and alignment between different roles in the organization.

Utilizing data-driven insights like the Product Backlog and its projections enables a constructive dialogue that is focused on outcomes and helps to align both the Scrum Team and the Project Manager toward achieving common goals.
