According to the PMBOK Guide, one of the tools and techniques for managing team resources is ground rules.
Ground rules are the standards of behavior that the team members agree to follow while working on the project. They can include topics such as communication, decision making, conflict resolution, meeting etiquette, and so on. Ground rules help to establish a common understanding and expectations among the team members, especially when they are geographically distributed and have different cultural backgrounds.
Developing protocols for resolving conflicts between team members is an example of setting ground rules that can help to address the development issues and improve productivity. Forcing the team members to work from one location, obtaining special expertise, or setting up face-to-face meetings are not the best options, as they may not address the root cause of the problem, may be impractical or costly, or may create more conflicts.
