In Tuckman’s team development model (forming, storming, norming, performing, adjourning), the storming phase is characterized by conflict, tension, and disagreement as members challenge ideas, roles, and ways of working. Option A describes this best: conflict that affects relationships. CompTIA Project+ includes people management concepts such as team dynamics and the need for PMs to apply leadership, conflict resolution, and motivation techniques as the team develops. ()

Option C describes forming (meeting and learning about the project). Option B describes performing (high-functioning, well-organized execution). Option D aligns with adjourning (closing/disbanding after work completion).

In storming, the PM’s role is to help the team move toward norming by clarifying goals and roles, setting working agreements, reinforcing communication norms, and addressing conflicts early and constructively. For a tax application (high accuracy/compliance needs), stabilizing team collaboration is crucial to reduce defects and rework. Therefore, the life-cycle description that matches storming is conflict affecting relationships. ()
