Key Concepts and Terminology
Planned Value (PV)
Planned Value (PV) is the authorized budget assigned to the work scheduled to be completed within a specific time frame. It represents the estimated cost of the planned work at a given point in time. PV is calculated by multiplying the planned percentage of work completed by the total budget allocated for the project.
Earned Value (EV)
Earned Value (EV) is the value of the work actually performed and completed at a specific point in time. It represents the budgeted cost of the work that has been accomplished. EV is calculated by multiplying the actual percentage of work completed by the total budget allocated for the project.
Actual Cost (AC)
Actual Cost (AC) is the total cost incurred in completing the work at a specific point in time. It represents the actual expenditure made on the project. AC includes all direct and indirect costs associated with the project, such as labor, materials, and overhead expenses.
Cost Variance (CV)
Cost Variance (CV) measures the cost performance of the project. It indicates the difference between the earned value and the actual cost. A positive CV indicates that the project is under budget, while a negative CV indicates that the project is over budget. CV is calculated by subtracting the actual cost from the earned value.
Schedule Variance (SV)
Schedule Variance (SV) measures the schedule performance of the project. It indicates the difference between the earned value and the planned value. A positive SV indicates that the project is ahead of schedule, while a negative SV indicates that the project is behind schedule. SV is calculated by subtracting the planned value from the earned value.
Cost Performance Index (CPI)
Cost Performance Index (CPI) is a ratio that measures the cost efficiency of the project. It indicates how efficiently the project is utilizing its budget. A CPI value greater than 1 indicates that the project is under budget, while a CPI value less than 1 indicates that the project is over budget. CPI is calculated by dividing the earned value by the actual cost.
Schedule Performance Index (SPI)
Schedule Performance Index (SPI) is a ratio that measures the schedule efficiency of the project. It indicates how efficiently the project is progressing compared to the planned schedule. An SPI value greater than 1 indicates that the project is ahead of schedule, while an SPI value less than 1 indicates that the project is behind schedule. SPI is calculated by dividing the earned value by the planned value.
Earned Value Calculation Techniques
Planned Value Technique
The Planned Value Technique is used to determine the planned value (PV) of the project. The following steps can be followed to calculate the PV:
- Break down the project into smaller tasks and assign a budget to each task.
- Estimate the percentage of work that should be completed for each task at a specific point in time.
- Multiply the budget allocated for each task by the planned percentage of work completed to calculate the planned value.
The Planned Value Technique helps project managers establish a baseline for the project’s planned budget and schedule. It provides a reference point for measuring the project’s performance and progress.
Earned Value Technique
The Earned Value Technique is used to calculate the earned value (EV) of the project. There are several methods to calculate the EV:
- Percentage of completion: This method involves estimating the percentage of work completed for each task and multiplying it by the budget allocated for that task.
- Unit of measure: This method involves measuring the work completed in units and multiplying it by the budget allocated per unit.
- Milestone: This method involves defining specific milestones in the project and assigning a budget to each milestone. The earned value is calculated based on the completion of these milestones.
The Earned Value Technique provides project managers with a quantitative measure of the work completed. It helps assess the project’s progress and performance accurately.
Actual Cost Technique
The Actual Cost Technique is used to determine the actual cost (AC) of the project. The following process can be followed to calculate the AC:
- Track and record all expenses incurred during the project, including labor costs, material costs, and overhead expenses.
- Sum up all the recorded expenses to calculate the total actual cost.
The Actual Cost Technique provides project managers with an accurate measure of the actual expenditure made on the project. It helps assess the project’s cost performance and control costs effectively.
Interpreting Earned Value Calculation Results
Understanding Cost Variance (CV) and Schedule Variance (SV)
Cost Variance (CV) and Schedule Variance (SV) provide insights into the project’s performance and indicate any deviations from the planned budget and schedule:
- Positive CV: A positive CV indicates that the project is under budget, meaning the actual cost is less than the earned value. This is a favorable outcome as it indicates cost savings.
- Negative CV: A negative CV indicates that the project is over budget, meaning the actual cost is greater than the earned value. This is an unfavorable outcome as it indicates cost overruns.
- Positive SV: A positive SV indicates that the project is ahead of schedule, meaning the earned value is greater than the planned value. This is a favorable outcome as it indicates progress ahead of the planned schedule.
- Negative SV: A negative SV indicates that the project is behind schedule, meaning the earned value is less than the planned value. This is an unfavorable outcome as it indicates delays in project progress.
By analyzing the cost variance and schedule variance, project managers can assess the project’s performance and take appropriate actions to address any deviations.
Analyzing Cost Performance Index (CPI) and Schedule Performance Index (SPI)
Cost Performance Index (CPI) and Schedule Performance Index (SPI) provide a more comprehensive assessment of the project’s cost and schedule performance:
- CPI value greater than 1: A CPI value greater than 1 indicates that the project is under budget, meaning the earned value is greater than the actual cost. This is a favorable outcome as it indicates cost efficiency.
- CPI value less than 1: A CPI value less than 1 indicates that the project is over budget, meaning the earned value is less than the actual cost. This is an unfavorable outcome as it indicates cost inefficiency.
