I am a relatively new scheduler to my company and new to project scheduling and earned value. My company has training sessions but some things remain unclear and the answers I am getting from some folks here do not make a lot of sense.
I am told there are several ways of claiming % complete and that each way has issues with them in terms of subjectivity or accuracy. I was told that physical % complete is the most accurate since it's something you can count. However, it does not make sense in terms of how planned value (PV or BCWS) is calculated and how I would take EV.
Here is the issue: I have three team members working a project that is supposed to last 20 days. 20 is my duration. This project will cost (BAC) $6,400. So my cumulative budget (S curve) across those 20 days is pretty much a straight line going up. So PV at day 10 will be $3,200.
Physically, the work is what they call back loaded so by day 10, they will only be 30% physically complete, so EV will only equal $1,920. This would mean that we are behind schedule when we really are not behind. Also, assuming costs are what they are supposed to be, AC would be, $3,200 and then this would mean we are also overrunning costs which would also not be accurate.
I am confused as to how physical complete is desired but then this scenario would make everything not accurate.
