The project scope statement and Work Breakdown Structure provide the project manager and team with the foundation for further planning. The scope statement and WBS answer the what, when, where, why type of questions but additional planning is required. The tasks and activities of the project must be arranged in the appropriate sequence to meet schedule requirements, mandatory dependencies, resource constraints, and other factors that affect the total or integrated project plan. Network scheduling is actually a continuation of the project planning process and allows the project team to determine the best approach to managing and controlling project activities. The process of network scheduling provides an opportunity to display the interdependencies of project activities; where float or slack exists, where there is flexibility in when activities may be performed, the critical path and opportunities for rearranging activities ensure the most efficient use of resources and available time.
