How can project team members use the duration specified in a project charter?

The duration specified in a project charter is primarily used to schedule tasks and plan timelines. This duration serves as a critical guideline for project planning as it provides a framework for when tasks need to be started and completed. By outlining the overall timeline, team members can break down the project into manageable phases and milestones, ensuring that all activities align with the project's deadlines. This planning allows for proper coordination of activities, helping to track progress and make adjustments as necessary to keep the project on schedule.

The other options focus on different aspects of project management. The scope of the project relates to the boundaries and deliverables, which doesn’t directly connect to the duration specified in the charter. Resource allocation is influenced by timelines but is more about determining how resources will be assigned rather than scheduling itself. Lastly, establishing team roles and responsibilities concerns the organization of the project team rather than the specifics of timing and scheduling set by the project charter.
