Which of the following is the comparison of planned project results with actual project results?

Variance analysis is the process of comparing the planned project results with the actual project results and identifying the causes and impacts of any deviations. Variance analysis helps project managers to monitor and control the project performance, identify and mitigate risks, and implement corrective actions or changes if needed. Variance analysis can be applied to various aspects of the project, such as scope, schedule, cost, quality, and resources. References:
