Earned Value

Summary:

Earned Value (EV) is a method for assessing and monitoring projects that measures the progress, costs, and value of a project over time. By understanding Earned Value, project managers can identify issues early on and take appropriate actions to ensure project success. This glossary entry explains the basics of Earned Value, how it is calculated, and its significance for project management.

Introduction

Earned Value is an important concept in project management that measures the true value and progress of a project over time. It is a performance-based method that evaluates project status in terms of time, costs, and scope and helps identify problems early on and take appropriate corrective actions. Earned Value is a valuable method for reviewing the health of a project and for predicting a project's future performance.

Basics of Earned Value

Earned Value links three fundamental elements of a project: the Planned Value (PV), the Actual Cost (AC), and the Earned Value (EV) itself.

Planned Value (PV)

The Planned Value is the estimated value of the planned work at a specific point in time. It is the financial value of the expected performance and is used to track the progress of the project over time.

Actual Cost (AC)

The Actual Cost is the real value of the work performed at a specific point in time. It is the financial value of the actual performance and is used to track the resources that have been used to complete the project.

Earned Value (EV)

The Earned Value is the financial value of the actual performance at a specific point in time. It measures the progress of the project in terms of Planned Value and Actual Cost and shows whether the project is on schedule and within budget.

Calculation of Earned Value

Calculating Earned Value involves using various metrics and indicators to analyze the performance, progress, and value of a project. Some of the key metrics are:

Cost Variance (CV)

Cost Variance is the difference between Earned Value and Actual Cost. It shows whether the project is under or over budget.CV = EV - AC

Schedule Variance (SV)

Schedule Variance is the difference between Earned Value and Planned Value. It shows whether the project is ahead or behind schedule.SV = EV - PV

Cost Performance Index (CPI)

The Cost Performance Index is the ratio of Earned Value to Actual Cost. It shows how efficiently the project uses resources.CPI = EV / AC

Schedule Performance Index (SPI)

The SchedulePerformance Index is the ratio of Earned Value to Planned Value. It shows how efficiently the project is staying on schedule.SPI = EV / PV

Significance of Earned Value in Project Management

The use of Earned Value in project management offers various benefits:

  • Performance Monitoring: Earned Value allows for continuous monitoring of a project's progress and detection of performance trends.
  • Early Detection of Problems: By analyzing Earned Value metrics, project managers can identify issues related to time, costs, or scope early on and take appropriate corrective actions.
  • Prediction of Future Performance: Earned Value can be used to predict future performance trends and create more realistic project completion forecasts.
  • Effective Resource Utilization: By understanding Earned Value, project managers can optimize resource usage and ensure that the project is conducted efficiently and economically.

Conclusion

Earned Value is an important approach in project management that measures the value and progress of projects over time. By using Earned Value metrics, project managers can monitor performance trends, identify issues early on, and take appropriate actions to ensure project success. Earned Value is a valuable method for assessing the health of a project and predicting its future performance.
