The cost side of the system remains constant (using budgeted cost figures) so the difference between the two amounts must be due to schedule deviations alone .A negative value indicates that the project is behind schedule as the “value” of work performed is less than that schedule. This is shown graphically in Figure 10 . that the schedule deviance is presented in terms of dollars, while in reality this is an indication of project status in terms of scheduled time.SV=BCWPBCWS (SV0: ahead of schedule, SV0: behind schedule)CV: Cost Variance: BCWP ACWP: The difference between the budgeted costs of work performed clearly indicates the status of the project in terms of cost. The work performed provides the mon unit of parison. A negative CV indicates the project is over budget as the actual costs exceed the budgeted costs. This is shown graphically in Figure 10 .2.CV= BCWP ACWP (CV0:under budget, CV0: over budge)These variances can be further expressed as ratios in percentage figures: % SV:% Schedule Variance: 100 SV/BCWS: This ratio indicates the percent deviation from the schedule based on budgeted cost values.% CV:% Cost Variance: 100 CV/BCWP: This measure gives the percentage deviation from the actual costs from what was budgeted for the work performed to date. Figure Earned Value Analysis Showing a Project that Is Ahead of Schedule Similarly, cost and schedule indicators can be measured as:SPI: Schedule Performance Index: BCWP/BCWS: This ratio provides a direct relationship between work performed and work scheduled based on budgeted costs. A value greater than indicates that more work has been performed than was scheduled, and thus the project is ahead of schedule.SPI=BCWP/BCWS (SPI1: ahead of schedule, SPI1: behind schedule)CPI: Cost Performance Index: BCWP/ACWP: This ratio directly pares budgeted costs to actual costs based on work performed. A value greater than indicates that the budgeted amount of the work is higher than what it actually cost, and therefore the project is under budget. Since dollars are not represented in the CPI, the results are sometimes
