What is EVM (Earned Value Management)?

This is an EVM graph

In today’s fast-paced project environments, ensuring that projects are completed on time and within budget is crucial for success. Earned Value Management (EVM) has long been a staple in project management for tracking progress and performance. However, automating EVM can expedite your analysis, allowing you to make faster, data-driven decisions. Let’s explore how automated EVM provides real-time insights and precise control over costs, schedules, and performance.

What is Earned Value Management (EVM)?

Earned Value Management is a method that allows project managers to measure project performance and progress in terms of money. It combines measurements of scope, schedule, and cost in a unified framework, providing a comprehensive view of the project’s health.

Key Components of EVM

Planned Value (PV)
The value of the work planned to be completed by a certain date.
Earned Value (EV)
The value of the actual work completed by a certain date.
Actual Cost (AC)
The actual cost incurred for the work completed by a certain date.
Schedule Performance Index (SPI)
A measure of schedule efficiency, calculated as SPI = EV / PV. An SPI greater than 1 indicates ahead of schedule, while less than 1 indicates behind schedule.
Cost Performance Index (CPI):
A measure of cost efficiency, calculated as CPI = EV / AC. A CPI greater than 1 indicates under budget, while less than 1 indicates over budget.
Budget at Completion (BAC):
The total budget allocated for the project.

1. Real-Time Insights

Automated EVM tools continuously gather and analyse data from various project components, offering immediate insights into project performance. This real-time visibility allows project managers to identify potential issues early and take corrective actions before they escalate.

2. Precise Control Over Costs and Schedules

By integrating automated EVM, project managers can precisely track cost variances and schedule performance indices. This precise control helps in maintaining the project’s budget and timeline, ensuring that any deviations are quickly addressed.

3. Enhanced Performance Management

With automated EVM, performance metrics are easily updated, providing an accurate picture of project health. Metrics such as Schedule Variance (SV) and Cost Variance (CV) become more reliable and actionable, enabling better resource allocation and project planning.

Practical Example

Consider a project to construct an office building with a total budget of $1,000,000, planned to be completed in 12 months. Here’s how EVM metrics come into play by the end of month 3:

Standard Earned Value Management Metrics:

Planned Value (PV)
By month 3, 25% of the work should be completed.
PV = $1,000,000 * 25% = $250,000
Earned Value (EV)
However, only 20% of the work is completed.
EV = $1,000,000 * 20% = $200,000
Actual Cost (AC)
The actual cost incurred is $280,000.
AC = $280,000

Calculating performance metrics:

Schedule Variance (SV)
SV = EV - PV = $200,000 - $250,000 = -$50,000 (behind schedule)
Cost Variance (CV)
CV = EV - AC = $200,000 - $280,000 = -$80,000 (over budget)
Schedule Performance Index (SPI)
SPI = EV / PV = $200,000 / $250,000 = 0.8 (progressing at 80% of the planned rate)
Cost Performance Index (CPI)
CPI = EV / AC = $200,000 / $280,000 = 0.714 (getting $0.714 worth of work for every dollar spent)

Forecasting Metrics

To predict future performance and costs:

Estimate at Completion (EAC)
If the project continues with the same cost performance (CPI),
EAC = BAC / CPI = $1,000,000 / 0.714 ≈ $1,400,560
Estimate to Complete (ETC)
The cost to complete the remaining work, given the current spending trend,
ETC = EAC - AC = $1,400,560 - $280,000 = $1,120,560
Variance at Completion (VAC)
The expected budget variance at project completion,
VAC = BAC - EAC = $1,000,000 - $1,400,560 ≈ -$400,560

Our EVM Analysis

By the end of month 3, our EVM analysis reveals significant insights into the project’s performance:

  • Schedule Performance: The negative Schedule Variance (SV) of -$50,000 and Schedule Performance Index (SPI) of 0.8 indicate that the project is behind schedule, completing only 80% of the planned work.
  • Cost Performance: The negative Cost Variance (CV) of -$80,000 and Cost Performance Index (CPI) of 0.714 highlight that the project is over budget, achieving only $0.714 worth of work for every dollar spent.
  • Forecasting: The Estimate at Completion (EAC) of approximately $1,400,560 suggests that if current trends continue, the project will significantly exceed its budget by around $400,560.

EVM provides a comprehensive view of a project’s health, combining both schedule and cost performance into actionable metrics. In our example, the project is facing both budget and schedule challenges, indicating the need for immediate corrective actions. 

Addressing Common Confusions

EVM can initially seem complex because it translates both time and money into monetary values. However, once you grasp that both schedule and cost performance are expressed in terms of money, it becomes a powerful tool for managing project performance effectively.


Earned Value Management (EVM) provides a robust framework for measuring and tracking project performance. By automating EVM, project managers can gain real-time insights, precise control over costs and schedules, and enhanced performance management capabilities. Automated EVM ensures that project objectives are met efficiently and effectively, leading to more successful project outcomes.
