Why schedule is important in planning

A schedule converts the plan into a time-table: it gives the start and finish time of every activity and the project completion date. It is important because:

• Fixes the completion date. The project duration and the critical activities are known.
• Co-ordinates work. Each party knows when its work starts and what must be finished before it.
• Resource planning. Labour, equipment and material are arranged in time from the schedule, avoiding idle time and shortage.
• Cash flow and finance. Payments, loan withdrawals and bills depend on when the work is done.
• Basis for control. Actual progress is compared with the schedule; delay is detected early and corrective action taken.
• Float is known. Non-critical activities can be shifted to level resources.
• Contract and claims. The approved schedule is used to assess delay, extension of time and liquidated damages.
• Communication. Gives clients and management a clear picture of progress.
