I just completed the acknowledged hardest one (scheduling and cost control) on Friday, (6/20/08) with a doozy of a test that gave me a stress head and neck ache you just wouldn't believe. Never being one who likes math, arithmetic or whatever, I memorized a BUNCH of PMI Earned Value Management Terms and Formulas... For example:
- PERT is a weighted average, to get it: O + 4ML +P/6
- Standard deviation: P - O/6
- Schedule Variance: EV - PV With values = 0 being good, - 0 bad and 0+ favorable
- Cost Variance: EV - AC With values = 0 being good, - 0 bad and 0+ favorable
- Schedule Performance Index: EV/PV, With values = 1 being good, - 1 bad and 1+ favorable
- Cost Performance Index: EV/AC, With values = 1 being good, - 1 bad and 1+ favorable
- Estimate to complete : ETC = EAC - AC
- Estimate at Completion: EAC = BAC / CPI or, EAC = AC + ETC or EAC = AC + (BAC - EV)
- Variance at Completion: VAC = BAC - EAC
Oy! Can you believe that crap is inside my little brain? Me neither! Last night at dinner with Tim at a cool Tappas restaurant I actually was able to converse intelligently about ROM (rough order of magnitude) and bottom up budget estimates and when to use them. Stop me when I start to babble... oh, ok, I'm babbling. I'll stop...
On a related note, Abby had the grace to wait until Saturday to leave this world. Had her stroke come any earlier, I would not have passed the exam, much less completed the class. What a good girl, huh?
