A. Planned Value (PV)
1. Definition and calculation of PV
Planned Value (PV) represents the authorized budget allocated for the work scheduled to be completed at a specific point in time. It is calculated by multiplying the budgeted cost of work scheduled (BCWS) by the percentage of work scheduled to be completed.
2. Importance of setting a baseline for PV
Setting a baseline for PV is crucial as it provides a reference point against which actual performance can be measured. It allows project managers to compare planned work against actual progress, identify deviations, and take corrective actions if necessary.
B. Earned Value (EV)
1. Definition and calculation of EV
Earned Value (EV) represents the value of the work actually completed at a specific point in time. It is calculated by multiplying the budgeted cost of work performed (BCWP) by the percentage of work completed.
2. Methods for determining the percentage of work completed
There are various methods for determining the percentage of work completed, including milestone-based measurement, percentage of physical completion, and subjective estimation based on expert judgment. The chosen method should be consistent, objective, and aligned with the project’s specific requirements.
C. Actual Cost (AC)
1. Definition and calculation of AC
Actual Cost (AC) represents the total cost incurred for the work performed at a specific point in time. It includes all direct and indirect costs associated with the project. AC is calculated by summing up the actual costs of all completed work packages.
2. Importance of tracking actual costs accurately
Tracking actual costs accurately is essential for maintaining project budget control and identifying any cost overruns or savings. It helps project managers make informed decisions regarding resource allocation, cost management, and project profitability.
D. Cost Variance (CV)
1. Definition and calculation of CV
Cost Variance (CV) measures the difference between the earned value (EV) and the actual cost (AC) of the work performed. It is calculated by subtracting AC from EV (CV = EV – AC).
2. Interpretation of positive and negative CV values
A positive CV value indicates that the project is under budget, meaning that the actual cost of the work performed is less than the value of the work completed. Conversely, a negative CV value indicates that the project is over budget, indicating that the actual cost of the work performed exceeds the value of the work completed.
E. Schedule Variance (SV)
1. Definition and calculation of SV
Schedule Variance (SV) measures the difference between the earned value (EV) and the planned value (PV) of the work performed. It is calculated by subtracting PV from EV (SV = EV – PV).
2. Interpretation of positive and negative SV values
A positive SV value indicates that the project is ahead of schedule, meaning that the value of the work completed exceeds the planned value at a specific point in time. On the other hand, a negative SV value indicates that the project is behind schedule, indicating that the value of the work completed is less than the planned value.
F. Cost Performance Index (CPI)
1. Definition and calculation of CPI
Cost Performance Index (CPI) measures the cost efficiency of the project by comparing the earned value (EV) with the actual cost (AC) of the work performed. It is calculated by dividing EV by AC (CPI = EV / AC).
2. Interpretation of CPI values
A CPI value greater than 1 indicates that the project is under budget, meaning that the value of the work completed is higher than the actual cost. Conversely, a CPI value less than 1 indicates that the project is over budget, indicating that the value of the work completed is lower than the actual cost.
G. Schedule Performance Index (SPI)
1. Definition and calculation of SPI
Schedule Performance Index (SPI) measures the schedule efficiency of the project by comparing the earned value (EV) with the planned value (PV) of the work performed. It is calculated by dividing EV by PV (SPI = EV / PV).
2. Interpretation of SPI values
An SPI value greater than 1 indicates that the project is ahead of schedule, meaning that the value of the work completed is higher than the planned value. Conversely, an SPI value less than 1 indicates that the project is behind schedule, indicating that the value of the work completed is lower than the planned value.
III. Implementing Earned Value Management in Project Planning
