A team charter is a document that a team creates to define their mission, goals, and the norms they will follow.
Having a team charter in place can help ensure that all team members are aligned and understand what is expected of them. Agreeing on core working hours within the team charter can address the issue of reduced and ineffective interactions due to varying individual start times. It sets a specific time frame during which all team members are available, thus maximizing the overlap in working hours and enhancing team collaboration and productivity.

Additionally, the Professional in Business Analysis Reference Materials also emphasize the importance of defining team roles and responsibilities, which can be effectively facilitated through a team charter3.
