1. Earned Value
$$$

2. Earned Value Measure of Project Performance Overall for All Activities
Measured at Particular Point in Times 13

3. Computing Earned Value
EV = (% Completed Work) (Planned Cost)
E.G. EV = .75 x 100 = 75
EV Also Known as: Budgeted Cost of Work Performed to Date (BCWP) 13

4. Using Earned Value
Cost Variance (CV) = EV (BCWP) – Actual Cost of Work Performed (ACWP) E.G. CV = 75 – 100 = -25 (Over Budget)
Schedule Variance (SV) = EV (BCWP) - Budget Cost of Work Scheduled (BCWS) E.G. SV = 75 – 125 = -50 (Costs behind Schedule)
Time Variance (TV) = Scheduled Time Work Performed (STWP) – Actual Time Work Performed (ATWP) E.G. TV = 20 – 25 = -5 (Behind Schedule) 13

5. Example: Problem 3.8 EV = (% Completed) (Planned Cost)
EV = (Actual Progress/Scheduled Progress) (100)
CR = (Actual Progress/Scheduled Progress) (Budget Cost/Actual Cost)
CR = (EV/100) (100/Actual Cost)
CR = EV/Actual Cost 13

6. CR for A: Over 6 Days Day A:EV A:Cost A: CR 1 90 95 .947 2 92 98 .939 13

7. CR for B: Over 6 Days Day B:EV B:Cost B: CR 1 90 95 .947 2 88 94 .936 13
