Integrating a new team member into an iterative project requires a supportive approach that ensures they understand the processes and can contribute effectively. Allocating time within the iterations for mentoring allows the new member to learn the necessary skills and processes in a structured manner. This aligns with the PMBOKGuide's principles of project team management and development, which emphasize the importance of continuous learning and improvement within the team. Mentoring provides a practical way to facilitate this learning, helping the new member to integrate into the team's workflow without negatively impacting the schedule1.
