Project Cost Management
(Level of difficulty: 4 / 10)

Try to understand and remember the formulas!
Resource Planning
- determine the resource requirement
Cost Estimating
- understand the differences between the tools and techniques
Cost Budgeting
- what is the cost baseline for?
Cost Control
- what is earned value management?
Don’t worry too much about earned value calculation. Rather straightforward. Try to understand the concept and logic behind the theory.
Formulas:
CV = EV - AC
SV = EV - PV
CPI = EV / AC
SPI = EV / PV
EAC = BAC / CPI (no variance)
EAC = AC ETC (assumptions were fundamentally flawed)
EAC = AC (BAC - EV) (variances are atypical and similar variances will not occur)
EAC = [AC (BAC - EV) /CPI ] (variances are typical and will change)
