A new member of a self-organizing team is struggling to deliver because the project uses unfamiliar technology. What should the project manager do?

The correct answer is to provide mentoring and necessary training to the team member. In a self-organizing team, the project manager's role shifts from directing to facilitating. When a team member struggles due to a skills gap, the most effective and supportive approach is to equip them with the knowledge and skills needed to succeed. This aligns with agile principles of continuous improvement and team development. Reassigning tasks might offer a short-term fix but doesn't address the root cause and can demotivate the team member. Asking the team member to transfer is an extreme measure that avoids addressing the issue. Enrolling them in a performance-improvement program via HR is premature and overly formal for a skills gap in new technology; a more direct, supportive, and in-team solution is preferred first.
