Projects have numerous activities that need to be planned and scheduled properly so that they may be completed on time. Planning identifies what activities are required whilst scheduling determines the sequence of these activities. Planners and Schedulers manage work priorities, schedules, work orders and plan revisions once there are design changes, unavailability of materials or services and other project disruptions. They typically use project controls and project management software to manage these functions.
