What is Earned Value Analysis?

Earned Value Analysis (EVA) uses Earned Value Management techniques to track the progress and performance of a project. It allows project managers to measure the value of work performed against the planned value, providing valuable insights into project performance.

By analysing the variance between what was planned, what has been performed and the actual costs, Earned Value Analysis enables project managers to forecast future project outcomes, identify potential issues and take proactive measures to ensure project success. This method not only helps in monitoring project progress but also offers a comprehensive view of project health by considering the time and cost dimensions.

With its ability to provide objective and quantitative measures of project performance, Earned Value Analysis has become an indispensable tool for project managers in monitoring and controlling project activities.

Earned Value Analysis is a vital tool in project management that provides performance measurement and accountability, especially for complex projects. It plays a critical role in monitoring and assessing project progress. EVA enables project managers to identify variances from the schedule and cost baselines, allowing them to take appropriate corrective actions.

Acting as an early warning system, EVA alerts project managers to potential issues and deviations before they become critical. By comparing the work completed (earned value) with the planned work (planned value), EVA enables accurate forecasting and estimation of project completion dates and costs. It helps project managers track compliance with the project plan, helping to ensure that the project is completed within the defined scope, schedule and budget.

EVA is an early warning indicator on how the project is performing. It facilitates cost and schedule control by identifying cost and schedule variances and determining their impact on project performance.

Additionally, EVA provides objective performance metrics, allowing project managers to evaluate and compare performance across different projects or phases. It aids in better decision-making by providing timely and accurate data on project progress, enabling project managers to make informed choices regarding resource allocation and risk management.

Furthermore, EVA provides historical data that can be used for future project planning and estimation. By analysing the performance trends from previous projects, project managers can tailor their plans and forecasts more effectively.

Lastly, EVA promotes continuous improvement by highlighting areas for improvement and evaluating the effectiveness of implemented changes. It enables project managers to identify lessons learned and best practices, leading to enhancements in project management strategies and processes.

By incorporating EVA into project management practices, organisations can enhance project success rates and achieve their objectives efficiently.

Earned Value Analysis examines the relationship between planned work, actual work and costs incurred to perform that work overtime. It provides crucial insights into project progress, efficiency and overall value.

Let’s review the components of earned value analysis:

Planned Value (PV):

• PV represents the authorised budget assigned to specific activities or work packages within a defined timeframe.
• It serves as a baseline for comparing actual performance and costs.
• Project managers use PV to evaluate whether the project is on track, ahead or behind schedule or over/under budget.

Earned Value (EV):

• EV reflects the value of work completed at any given point in the project.
• It provides a tangible measure of progress.
• Calculated based on the budgeted cost of completed work.
• EV helps assess whether the project is meeting its objectives.

Actual Cost (AC):

• AC represents the actual costs incurred during project execution.
• It includes labour, material, subcontractors and other direct costs. It includes both direct and indirect costs.
• By comparing AC with EV and PV, project managers can identify cost discrepancies.

Budget at Completion (BAC):

• BAC is the total budget allocated for the entire project.
• It serves as a reference point for evaluating overall project performance.

Variance Analysis and Performance Indexes:

• Cost Variance (CV): Measures the difference between EV and AC. Positive CV indicates cost savings, while negative CV suggests cost overruns.
• Schedule Variance (SV): Compares EV with PV. Positive SV indicates work ahead of schedule, while negative SV indicates delays.
• Cost Performance Index (CPI): CPI assesses cost efficiency by dividing EV by AC. A CPI greater than 1 indicates favorable cost performance.
• Schedule Performance Index (SPI): SPI evaluates schedule efficiency by dividing EV by PV. An SPI greater than 1 indicates favorable schedule performance.

Forecasting:

• Estimate at Completion (EAC): Predicts the total project cost based on current performance.
• Estimate to Complete (ETC): Estimates remaining costs to complete the project.
• To-Complete Performance Index (TCPI): Indicates the required performance to meet budget goals.

Earned Value (EV) is a way to assign a dollar amount to progress. Once you determine the percent complete of a task, you multiply the budget of the task by the percent complete. Earned Value (EV) calculation methods include the 0/100, 50/50 and Weighted Milestone methods. These earned value methods are used to reduce the subjective nature of percent complete:

1. The 0/100 method is an objective technique used to measure progress on an activity or task. This method assumes that no work is considered earned until the entire task is completed. This means that the full value of the task is only earned once it is fully finished. This can be seen as a binary approach, where either the full value is earned or none at all.
2. The 50/50 method is another objective technique used for calculating the Earned Value. This approach assumes that 50% of the task value is earned at the start of the effort and the remaining 50% is earned upon completion. This method acknowledges that some progress is made at the start of a task but recognises that the full value is only earned once the task is finished.
3. The Weighted Milestone method involves assigning weightings to different milestones or deliverables in a project. Each milestone is assigned a percentage based on its relative importance or difficulty. This method allows for a more nuanced evaluation of progress as different milestones contribute different values to the overall project. This approach is useful when there are multiple milestones or deliverables that carry varying levels of significance.

Each method offers a different perspective on progress evaluation and can be used depending on the specific project requirements.

Cost Variance (CV) is a commonly used measure in project management to assess the performance of a project in terms of cost. It helps project managers determine whether the project is running over or under budget.

To calculate the Cost Variance, you subtract the actual cost of a task or project from the earned value.

The formula for calculating Cost Variance is: CV = Earned Value (EV) - Actual Cost (AC)

EV represents the value of the work completed at a given point in time, while AC represents the actual cost of completing that work.

The significance of Cost Variance lies in its ability to provide insight into the project's cost performance. A positive CV indicates that the project is under budget, which is generally favorable as it implies cost savings. Conversely, a negative CV suggests that the project is over budget, signaling cost overruns.

Interpreting positive and negative values is straightforward. A positive CV means that the project is performing better than expected in terms of cost, indicating efficiency and potential cost savings. On the other hand, a negative CV suggests that the project is not performing well in terms of cost and is exceeding the planned budget.

By monitoring Cost Variance closely, project managers can make informed decisions regarding necessary adjustments to control costs and keep project costs on track.

Schedule Variance (SV)

Schedule Variance (SV) is a key metric in project management that indicates the project's progress in terms of schedule. It measures the difference between the planned value of the work completed (Earned Value or EV) and the planned value of the work that was supposed to have been completed by a certain point in time (Planned Value or PV).

The formula to calculate Schedule Variance is: SV = EV - PV.

EV represents the value of work completed at a given point in time, while PV represents the planned value of work that was to be completed by that same point in time.

When the Schedule Variance (SV) is 0, it indicates that the project is on schedule. This means that the value of work completed matches the planned value of work at that point.

A positive Schedule Variance indicates that the project is ahead of schedule. This means that the value of work completed exceeds the planned value of work, indicating that the project is progressing faster than anticipated.

On the other hand, a negative Schedule Variance indicates that the project is behind schedule. This means that the value of work completed is less than the planned value, suggesting that the project is progressing slower than expected.

Analysing Schedule Variance analysis helps project managers to identify if a project is running on schedule, ahead of schedule or behind schedule. This information enables proactive decision-making and adjustments to keep the project on track and avoid potential delays.

Cost Performance Index (CPI)

The Cost Performance Index (CPI) is a project management metric used to assess the cost efficiency of a project. It is calculated by dividing the earned value (EV) by the actual cost (AC) of the project: CPI = EV/AC

The earned value represents the value of the work completed or the budgeted cost of the work performed, while the actual cost refers to the actual money spent on the project. By comparing these two figures, the CPI provides insights into whether the project is performing above, below or on budget.

A CPI greater than 1 indicates that the project is under budget, meaning that the earned value is higher than the actual cost. This suggests that the project is cost-efficient and is achieving more value for the money spent.

On the other hand, a CPI less than 1 suggests that the project is over budget. In this case, the earned value is lower than the actual cost, indicating that the project is inefficient and costing more than originally planned.

A CPI equal to 1 means that the project is on budget. The earned value and the actual cost are aligned, indicating that the project is progressing as planned in terms of cost.

The Cost Performance Index (CPI) helps project managers monitor and evaluate the cost efficiency of their projects.

Schedule Performance Index (SPI)

The Schedule Performance Index (SPI) is a measure used to assess the efficiency and progress of the project schedule. It compares the earned value (EV) to the planned value (PV) and provides valuable insights into the project's timeline.

To calculate the SPI, divide the EV by the PV: SPI = EV/PV

The EV represents the value of completed project activities at a specific point in time, while the PV represents the planned value of the work scheduled to be completed. By dividing these figures, the SPI provides a ratio indicating if the project is running ahead of schedule, on schedule or behind schedule.

The interpretation of SPI values is critical in understanding the project's status. An SPI above 1 suggests that the project is ahead of schedule, as the earned value is greater than planned value. This indicates that work is being completed more quickly than anticipated, potentially leading to early project completion.

Conversely, an SPI below 1 signifies a delay, with the earned value falling short of the planned value. This implies that the project is progressing slower than expected and may require adjustments to maintain the desired timeline.

An SPI equal to 1 represents an on-schedule project, where the earned value matches the planned value.
