The project manager should conduct a meeting with the project team to discuss and address the sources of disagreement, as this is a strategy for improving team morale and performance.
According to the PMI website, one of the interpersonal and team skills that a project manager should have is conflict management. Conflict management is the process of resolving or reducing disagreements among project stakeholders, such as team members, sponsors, customers, or suppliers. Conflict can arise due to various factors, such as personality differences, communication barriers, resource constraints, or competing interests. If not managed properly, conflict can negatively affect the team morale, productivity, quality, and satisfaction. The project manager should use appropriate conflict resolution techniques, such as problem-solving, compromising, collaborating, smoothing, or forcing, depending on the situation and the desired outcome. The project manager should also facilitate open and constructive communication, encourage feedback and participation, and promote trust and respect among the team members.
By conducting a meeting with the project team, the project manager can identify the root causes and the impact of the disagreement, and work with the team to find a mutually acceptable solution. The project manager can also clarify the project objectives, scope, and requirements, and ensure that the team members understand their roles and responsibilities. By addressing the sources of disagreement, the project manager can improve the team morale and performance, and get the project back on track.
