A new resource has joined an iterative project team. The project manager notices that the resources is unable to complete the deliverables on time. How should the project manager address this situation?

While providing feedback during a retrospective is valuable, it addresses performance issues too late in the project cycle. Retrospectives are meant for reflecting on past work rather than actively resolving ongoing performance challenges. Immediate intervention is necessary to support the new resource effectively.

Requesting a replacement resource might seem like a quick fix, but it fails to address the root cause of the performance issue. This option could also disrupt team dynamics and project continuity, leading to further delays. It's generally more productive to explore ways to develop and support existing team members before considering replacements.

Extending the new team members does not inherently resolve performance issues; it may only prolong their struggles without offering constructive solutions. Instead of merely extending timelines, the project manager should engage in proactive discussions with the resource manager to facilitate performance improvement and ensure timely deliverables.
