A team is formed for a project using a predictive approach for requirements and an agile approach for development and testing. Some team members lack agile experience. The schedule started slipping because the agile development approach was unclear. What should the project manager have done to prevent this?

The correct answer addresses the root cause: the team's lack of agile experience and the resulting unclarity in the agile development approach. By meeting with the team, allowing them to make decisions, and establishing performance goals, the project manager fosters self-organization and empowers the team to adapt and learn the agile approach. This proactive approach builds team capability and ownership, preventing schedule slips. The other options are reactive or less effective. Setting up weekly status meetings and reports (A) or daily standups (B) primarily tracks and reports delays rather than preventing them. Identifying underperforming team members (D) is a reactive measure that doesn't address the underlying issue of unfamiliarity with the agile approach.
