Consider the following project involving 5 activities. The planned duration of the project is 10 months, and the cost baseline (in \$) is shown in the following table. Suppose at the end of month 9 , it is found that totally $250,000 has already been spent on this project. Activity A has been completed. Activities B, C and D have been 70% completed (that is, 70% of each entire activity), and Activity E has not been started yet. Perform Earned Value Management at the end of month 9: calculate the planned value, earned value, cost variance and schedule variance for the project. Comment on the performance of the project based on the EVM analysis
