The delivery of the pilot courses has been split into two separate products: 'planned pilot courses' and 'delivered pilot courses'. 'Planned pilot courses' will be produced during stage 3, and the 'delivered pilot courses' will take place during stage 4. This will allow the project board to approve the plan for the pilot courses before the resources are committed to delivering the pilot courses.
Why is this an appropriate application of the plans theme to control the project?
