Obsessiveâcompulsive disorder affects about 2.3% of people at some point in their life. Rates during a given year are about 1.2% and it occurs worldwide. It is unusual for symptoms to begin after the age of thirty-five and half of people develop problems before twenty. Males and females are affected about equally.
Variance At Completion (VAC) per Project. Variance at Completion (VAC) is a project management key performance indicator that shows the difference (in dollars) between the starting project budget (Total Budgeted Cost) and the forecasted project budget when the project is complete (Estimate at Completion or EAC).
Schedule Variance. Schedule variance is very similar to cost variance. So some of the explanation here also appears in the CV proof as some the variables are the same and the same concepts are used. As stated under cost variance, when you are mid-project there are two units by which you can measure your progress: time and money. Schedule variance measures progress and in terms of time. But here we measure time in dollars. It's counter-intuitive, but schedule variance does not measure progress in time-based units. We are measuring progress in dollars not manhours. The SV formula is SV = EV-PV. EV is earned value and PV is planned value.
