What is variance analysis used for?

Variance analysis

Variance analysis Project managers should pay attention to critical and subcritical activities when evaluating project time performance. One way to do this is to analyze 10 subcritical paths in order of ascending float. This approach is part of—   a. Variance analysis  b. Simulation  c. Earned value management  d. Trend analysis  Answer: a. Variance analysis  Performance of variance analysis Performance of variance analysis during the schedule monitoring process is a key element of time control. Float variance is an essential planning component for evaluating project time performance. [Monitoring and Controlling]
