When you are calculating the percent complete for an entire project, more than one answer might be possible. The project manager says the percent complete is about 60%, the cost engineer says it is 65%, the computer programmer says it is 57%, and the owner says it should be 50% (according to her representatives feedback). You calculate it on the basis of how much time has elapsed and how much time is given in the contract; your result is 70%. Can you explain these confusing and "conflicting" numbers?
