Purpose of Scheduling
Many decisions made during the estimating process relate to the
schedule for completing the project. In fact, a preliminary schedule is some-
times prepared in the process of creating an estimate. Once the contract is
awarded, a more detailed schedule is prepared to guide the project.
A schedule lists the sequence in which tasks will be completed.
Managers use the schedule to determine when workers, materials, and
equipment are needed. Adding information about daily progress to the
planned schedule alerts managers to tasks that are not proceeding as
planned. Corrective action can be taken to get the project back on schedule.
The schedule can also be used to track the expenditure of money. Summary
charts indicate the amount of money that has been spent compared to what
was planned. As with daily progress, early identification of money problems
improves the opportunity to solve the problems.
