Scheduling converts the project action plans for scope, time, cost, and quality into an operating timetable. The translation of the project criteria for scope, time, cost, and quality and the requirements for human resources, communications, risk, and procurement into workable “machinery” for the project team is a critical interface juncture for the project team. Taken together with the project plan and budget, the schedule becomes the major tool for the management of projects. In addition, the integrated cost-time schedule serves as the fundamental basis for monitoring and controlling project activity throughout its life cycle.
