Earned Value vs. Value of Work Done

Attribute	Earned Value	Value of Work Done
Definition	Measure of the budgeted cost of work actually performed	Measure of the budgeted cost of work that has been completed
Calculation	Planned Value x % Complete	Actual Cost x % Complete
Focus	Focuses on the budgeted cost of work performed	Focuses on the budgeted cost of work completed
Use	Used to measure project performance and progress	Used to assess the value of work completed at a specific point in time

Introduction

When it comes to project management, two important metrics that are often used to measure progress are Earned Value (EV) and Value of Work Done (VOWD). While both metrics provide valuable insights into the performance of a project, they have distinct attributes that make them suitable for different purposes.

Definition

Earned Value is a method used to track the progress of a project by comparing the budgeted cost of work performed to the actual cost of work performed. It provides a snapshot of how much value has been earned by the project at a specific point in time. On the other hand, Value of Work Done is a measure of the value of the work that has been completed on a project, regardless of the cost incurred.

Calculation

The calculation of Earned Value involves multiplying the planned percentage of work completed by the total budgeted cost of the project. This gives a dollar value representing the work that should have been completed at that point in time. In contrast, the calculation of Value of Work Done is simply the sum of the budgeted costs of the work that has been completed so far.

Usefulness

Earned Value is particularly useful for assessing the performance of a project in terms of cost and schedule. By comparing the planned value of work completed to the actual value of work completed, project managers can identify any discrepancies and take corrective actions. On the other hand, Value of Work Done is more focused on measuring the progress of a project in terms of the work that has been completed, regardless of the cost.

Integration

Both Earned Value and Value of Work Done can be integrated into a project management system to provide a comprehensive view of project performance. By using both metrics together, project managers can gain a more holistic understanding of how a project is progressing and make informed decisions about resource allocation and scheduling.

Benefits

One of the key benefits of Earned Value is its ability to provide early warning signs of potential cost overruns or schedule delays. By comparing the planned value of work completed to the actual value of work completed, project managers can identify variances and take corrective actions before they escalate. On the other hand, Value of Work Done provides a clear picture of the progress of a project in terms of the work that has been completed, which can be useful for tracking milestones and setting realistic expectations.

Conclusion

In conclusion, both Earned Value and Value of Work Done are valuable metrics for measuring project performance. While Earned Value is more focused on cost and schedule performance, Value of Work Done provides a clear picture of the progress of a project in terms of the work that has been completed. By using both metrics together, project managers can gain a comprehensive view of how a project is progressing and make informed decisions about resource allocation and scheduling.
