An agile project manager notices a team member gaining deep knowledge in a specific area that other team members will likely need later. What should the agile project manager do?

The correct answer is to ask the team member to provide a training session. In agile, cross-functional teams and shared knowledge are crucial for adaptability and reducing single points of failure. A training session directly facilitates knowledge transfer, empowering other team members and enhancing the team's collective capability. While developing more expertise is good, simply asking them to do so doesn't address the immediate need for knowledge sharing. Lessons learned documents and recorded highlights are valuable for documentation and future reference, but they are less effective than direct training for immediate skill transfer and interactive learning within the team.
