During the retrospective ceremony, the agile team is talking about the product owner's expectations not being met. What should the project manager have done at the beginning of the project?

Defining the team's contribution to backlog creation is important, but a lack of clarity here might lead to inefficient backlog management, not necessarily unmet Product Owner expectations regarding the *product itself*.

Assessing team capabilities and planning training addresses performance issues or skill gaps, but it doesn't directly solve a misalignment with Product Owner expectations which stems from a lack of understanding of the product's objectives.

Defining team ground rules fosters team cohesion and efficiency, but while important, it doesn't directly address the critical communication of what needs to be built to meet the Product Owner's strategic vision.

Clear communication of the project vision and sprint goals is fundamental in agile, serving as the guiding north star for the team. This ensures the team understands what they are trying to achieve and why, enabling them to prioritize, make informed decisions, and align their work with the Product Owner's expectations and overall project objectives from the beginning.
