The schedule develops as the project moves from its early conceptual phase into the execution phase.
When the scope of the project is being determined, a simple schedule that shows the major tasks and approximate start and end dates is developed to allow senior management to make decisions about the scope of the project. Detail is not required at this stage because entire tasks might be dropped from the scope, or the whole project might not be approved.
If the project is chosen, a master schedule is created. It has major events and dates such as the starting date and the completion date. The master schedule is often part of a contract. Changes to the master schedule must be approved using a documented change process with approval by the project sponsor and client.
To execute the master schedule, the major activities are broken down into smaller activities and resources are assigned to those activities. The most detailed versions or portions of the schedule may be developed a few weeks prior to the execution of those activities and are called two-week plansThe most detailed version or portion of the schedule that is developed a few weeks prior to the execution of those activities.. Portions of the master schedule that affect particular vendors might be sent to them so they can provide detailed activities that they would perform.
Conceptual Schedule
Choose an activity that you are considering and describe a conceptual schedule for it. Limit the schedule to between five and ten major sections. Make a rough estimate of the duration and cost of each phase.
