Explanation
In an agile project, the project manager should work with the product owner and the team to prioritize the backlog items based on their value, risk, and dependencies. This way, the most important and urgent items can be delivered first, and the scope can be adjusted according to the feedback and changes in the environment.
Prioritizing the backlog also helps to manage the expectations of the stakeholders and align them with the project vision and goals. Assigning an owner for each backlog activity and tracking progress (A) is not the best option, as it does not address the issue of having too many items in the backlog and how to select the ones that should be done. Asking for more resources to clear the backlog activities (B) is not feasible, as the project has a fixed budget and adding more resources may not improve the productivity or quality of the project. Working on the backlog activities with fewer story points (D) is not a good strategy, as it may lead to ignoring the items that have higher value or risk, and may not deliver the expected outcomes or benefits to the customer or the business.
