Understanding Earned Value in Project Management
Earned Value is a valuable tool in project management that helps you track the progress and performance of your projects. It combines information about the planned cost, actual cost, and progress of the project to provide a clear and meaningful measure of its performance. By calculating the earned value, you can gain insights into the efficiency and effectiveness of your project, allowing you to make informed decisions and take corrective actions when necessary.
Definition of Earned Value
Earned Value is a metric used in project management to measure the value of work that has been completed to date. It is calculated by multiplying the actual percentage of work completed by the planned value of the project. In other words, it represents the budgeted cost of work that has been completed according to the project schedule.
Purpose of Calculating Earned Value
The primary purpose of calculating the earned value is to assess the progress and performance of a project in an objective and quantifiable manner. By comparing the earned value to the planned value and the actual cost, you can determine whether the project is ahead of schedule, behind schedule, over budget, or under budget. This information helps you identify any variances and trends early on, enabling you to take corrective actions and ensure project success.
Benefits of Using Earned Value in Project Management
There are several benefits to using earned value in project management. Firstly, it provides an objective and accurate measure of a project’s progress and performance, allowing you to assess its health and make informed decisions. Secondly, it enables you to identify and analyze variances between planned and actual performance, helping you understand the reasons behind these discrepancies and take necessary actions. Lastly, it allows for effective project forecasting, as you can use the earned value data to predict future performance and make adjustments to meet project goals.
Components of Earned Value Calculation
To calculate the earned value, you need to consider three main components: planned value (PV), actual cost (AC), and earned value (EV).
Planned Value (PV)
Planned value (PV), also known as the budgeted cost of work scheduled (BCWS), refers to the estimated value of the work that was planned to be completed up to a specific point in time. It is often represented as a budgeted cost or a percentage of the total budget allocated to the project.
Actual Cost (AC)
Actual cost (AC), also known as the actual cost of work performed (ACWP), represents the actual cost incurred in completing the work up to a specific point in time. It includes all the costs associated with the project, such as labor, materials, and overhead expenses.
Earned Value (EV)
Earned value (EV), also known as the budgeted cost of work performed (BCWP), reflects the value of the work that has actually been completed up to a specific point in time. It is typically calculated by multiplying the actual percentage of work completed by the planned value of the project.
Calculating Planned Value (PV)
Determining the planned value requires a clear understanding of the project scope, schedule, and budget. It involves estimating the value of the work that is planned to be completed within a specific time frame.
Determining Planned Value Formula
The formula for calculating the planned value (PV) is as follows:
Planned Value (PV) = Planned Percentage of Work Completed * Total Project Budget
Example of Calculating Planned Value
Let’s assume you are working on a project with a total budget of $10,000 and the planned percentage of work completed after a certain period is 50%. To calculate the planned value, you would multiply the planned percentage of work completed (50%) by the total project budget ($10,000):
Planned Value (PV) = 0.50 * $10,000 = $5,000
Therefore, the planned value of the project after that specific period would be $5,000.
Calculating Actual Cost (AC)
Calculating the actual cost requires tracking and recording all the expenses incurred throughout the project. This includes labor costs, material costs, subcontractor costs, and any other expenses directly related to the project.
Determining Actual Cost Formula
The formula for calculating the actual cost (AC) is as follows:
Actual Cost (AC) = Sum of all costs incurred for the project up to a specific point in time
Example of Calculating Actual Cost
Let’s say you have gathered all the expenses for your project up to a certain date, and the total cost amounts to $7,500. To determine the actual cost, you would use this value:
Actual Cost (AC) = $7,500
Therefore, the actual cost of the project up to that specific date would be $7,500.
Calculating Earned Value (EV)
To calculate the earned value, you need to determine the percentage of work completed and multiply it by the planned value of the project.
Determining Earned Value Formula
The formula for calculating the earned value (EV) is as follows:
Earned Value (EV) = Percentage of Work Completed * Planned Value (PV)
Example of Calculating Earned Value
Let’s assume that after a certain period, the percentage of work completed is 70% and the planned value is $5,000. To calculate the earned value, you would multiply the percentage of work completed (70%) by the planned value ($5,000):
Earned Value (EV) = 0.70 * $5,000 = $3,500
Therefore, the earned value of the project after that specific period would be $3,500.
Using Earned Value to Assess Project Performance
Once you have calculated the earned value, you can use it to assess the performance of your project by calculating various performance indices.
Schedule Variance (SV)
Schedule Variance (SV) measures the schedule performance by comparing the earned value (EV) to the planned value (PV). It indicates whether the project is ahead or behind schedule.
Cost Variance (CV)
Cost Variance (CV) measures the cost performance by comparing the earned value (EV) to the actual cost (AC). It indicates whether the project is over or under budget.
Schedule Performance Index (SPI)
Schedule Performance Index (SPI) measures the efficiency of the project’s schedule by comparing the earned value (EV) to the planned value (PV). It indicates whether the project is ahead or behind schedule, taking into account the budgeted cost.
Cost Performance Index (CPI)
Cost Performance Index (CPI) measures the efficiency of the project’s cost by comparing the earned value (EV) to the actual cost (AC). It indicates whether the project is over or under budget, taking into account the work completed.
Interpreting Schedule Variance (SV) and Cost Variance (CV)
To interpret the schedule variance (SV) and cost variance (CV), you need to understand their definitions and the implications of positive and negative values.
Definition of Schedule Variance
Schedule Variance (SV) is calculated by subtracting the planned value (PV) from the earned value (EV). A positive SV indicates that the project is ahead of schedule, while a negative SV indicates that the project is behind schedule.
Definition of Cost Variance
Cost Variance (CV) is calculated by subtracting the actual cost (AC) from the earned value (EV). A positive CV indicates that the project is under budget, while a negative CV indicates that the project is over budget.
Interpreting Positive and Negative Values
Positive values for both schedule variance (SV) and cost variance (CV) are generally favorable, as they indicate that the project is performing better than planned. Negative values, on the other hand, are unfavorable and suggest that the project is not meeting its objectives as expected.
Evaluating Schedule Performance Index (SPI) and Cost Performance Index (CPI)
The schedule performance index (SPI) and cost performance index (CPI) provide insights into the efficiency and effectiveness of the project’s schedule and cost performance.
Definition of Schedule Performance Index
Schedule Performance Index (SPI) is calculated by dividing the earned value (EV) by the planned value (PV). An SPI greater than 1 indicates that the project is ahead of schedule, while an SPI less than 1 indicates that the project is behind schedule.
Definition of Cost Performance Index
Cost Performance Index (CPI) is calculated by dividing the earned value (EV) by the actual cost (AC). A CPI greater than 1 indicates that the project is under budget, while a CPI less than 1 indicates that the project is over budget.
Interpreting SPI and CPI Values
SPI values above 1 indicate good schedule performance, while values below 1 suggest poor schedule performance. CPI values above 1 indicate good cost performance, while values below 1 suggest poor cost performance. It is important to consider these indices together with the schedule variance (SV) and cost variance (CV) for a comprehensive understanding of the project’s performance.
