According to the PMBOKGuide, conflict resolution is an essential skill for project managers. The guide suggests that conflicts should be addressed early and in a private setting using an open and collaborative approach1.

It allows the project manager to identify the root cause of the conflict and work towards a resolution before escalating the issue or considering alternative options.
