During the forming stage of team development, it is common for team members to be polite and avoid conflict, but disagreements can still occur. Establishing team ground rules is a proactive approach to prevent conflicts and ensure that all team members are on the same page. This strategy aligns with the PMBOK Guide's emphasis on collaboration and team engagement as key components of project management. By collaborating on ground rules, the team can address disagreements in a structured manner and support a positive team environment, which is crucial for the subsequent stages of team development.
