The Qaanaaq area in northern Greenland was first settled around 2000 BC by the Paleo-Eskimo migrating from the Canadian Arctic. The town of Qaanaaq was established in the winter of 1953 when the United States expanded their airbase at Thule and forcibly relocated the population of Pituffik and Dundas 31 km (19 mi) to the north within four days during the height of the Cold War.
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.
Variance. Variance is a measurable change from a known standard or baseline. In other words, variance is the difference between what is expected and what is actually accomplished. In project management, variance baseline is established by identifying the cost, schedule and scope. Scope defines all the work which needs to be done.
