Q

The Earned Value Method (EVM) is recognized as an effective project monitoring and control tool in the project management industry, endorsed by DOE, DOD, and NASA. Explain two benefits of EVM

Q

As of the sixth month on a building project, cumulative planned value was $10,000. Actual cost during this period totaled $8,000. How is this project doing?

A

This project is doing good because according to the definition of planned value and actual costs, the project is ahead of schedule.

Q

Are the schedule evaluations from CPM and EVM consistent? If not, what causes the differences?

A

Critical Path method is designed to display the total time a project takes with given circumstances what activities would be delayed if another was delayed. it also gives the total amount an activity can be delayed. The earned value method is designed to track spending with the work done. shows how much events costs with a given schedule. They both work together but are different in nature.

Q

Either CPM or EVM, which method do you recommend as better schedule evaluation? Why?

A

I would recommend CPM for purely a schedule evaluation. it is designed to show the delays and errors with time. It can then be used to help build upon when and where to do certain activities. If someone were looking for cost considerations, I would recommend the EVM.

35
Q

List two strengths and limitations of the window technique
