The Control Model (continued)
Project Control is making sure project plans succeed. Controlling is Measuring progress toward project objectives, Evaluating that progress, and taking Corrective Action to achieve or exceed project objectives.

Measuring: Determine the amount of progress made. Evaluating: Determine the causes or potential causes for variances between planned and actual performance and possible ways to correct or avoid problems. Correcting: Take management actions to correct an unfavorable trend or to take advantage of a favorable trend.
