During the Monitoring and Control Project Work process, a project manager analyzes performance data to determine whether any corrective or preventive action is needed. Which valid input can be used for this activity?

The project manager needs to evaluate work performance information against the plan. Work performance data represents raw data used in executing the work, which later becomes information as it is analyzed against baselines through other processes within the Monitoring and Controlling process group. Variance analysis and expert judgment are tools and techniques used in the process, rather than inputs.
