Pick up the main purpose of project cost control from the following: A. To signal immediate warning of uneconomic operations B. To provide a feed back to the estimator C. To promote cost consciousness D. All of these

The correct answer is D. All of these.

Project cost control is the process of monitoring and controlling costs throughout the life of a project. It is important to identify and correct any cost overruns as early as possible to avoid project delays or even failure.

There are three main purposes of project cost control:

1. To signal immediate warning of uneconomic operations. This means identifying any cost overruns as early as possible so that corrective action can be taken.
2. To provide a feedback to the estimator. This means providing information on the actual costs incurred so that the estimator can improve their estimates for future projects.
3. To promote cost consciousness. This means raising awareness of the importance of cost control and encouraging everyone involved in the project to be mindful of costs.

All three

of these purposes are important for the success of a project. By identifying and correcting cost overruns early, project managers can avoid delays and even failure. By providing feedback to the estimator, project managers can improve their estimates for future projects. And by promoting cost consciousness, project managers can encourage everyone involved in the project to be mindful of costs and help to keep the project on track.
