During project execution you found out that work is often not performed at the right time and in the right order. Deliverables are made by one team member that cannot be processed by another one. This already leads to timely rework and bad morale among team members. Which project management tool is most appropriate to deal with problems like this?

A work authorization system is the most appropriate project management tool for dealing with problems like this because it defines the processes and procedures for initiating, planning, executing, and controlling work within a project. It ensures that work is performed at the right time and in the right order and prevents team members from working on deliverables that cannot be processed by others. This helps to avoid timely rework and maintain good morale among team members. The other options, such as an organization chart, RACI matrix, and communications management plan, may be useful for other aspects of project management but they do not directly address the issue of work not being performed at the right time and in the right order.
