During the retrospective, the agile team discusses that the product owner's expectations were not met. What should the project manager have done at the start of the project?

The correct answer is communicating the project vision and sprint goals clearly to the team. A lack of clear communication regarding the project vision and sprint goals often leads to unmet expectations because the team may not fully understand what they are working towards or what success looks like. By ensuring the team understands the "why" behind the work and the specific objectives for each sprint, the project manager helps align their efforts with the product owner's expectations from the outset. Defining the expected agile team contribution to creating the backlog is important but less impactful than understanding the overall vision. Assessing capabilities and planning training is crucial for team performance but doesn't directly address unmet expectations stemming from a lack of understanding of the project's direction. Defining team ground rules is essential for team dynamics but doesn't resolve a disconnect in project objectives.
