What is the EVM
Comprehensive Report?
Nahla AI's Earned Value Management (EVM) Comprehensive Report
is a one-click generated analysis that gives you complete visibility into your
project's cost and schedule performance. It combines PMI-standard calculations
with AI-powered insights to help you make data-driven decisions.
Key Benefit: Instead of manually calculating EVM
metrics in spreadsheets, Nahla generates a professional report in seconds with
actionable recommendations for each section.

Overview
The 4 EAC
Calculation Methods
One of the most powerful features of
Nahla's EVM Report is the ability to switch between 4 PMI-standard EAC calculation
methods. This allows you to compare different forecasting
scenarios based on your project's circumstances.
Method 1: EAC = BAC / CPI (Typical)
EAC = BAC / CPI
Use when: You expect future cost performance to
match current CPI. This is the most commonly used method when variances are
expected to continue.
Method 2: EAC = AC + (BAC - EV) (Atypical)
EAC = AC + (BAC - EV)
Use when: Current variances are atypical and won't
recur. Remaining work will be completed at the original budgeted rate.
Method 3: EAC = AC + (BAC - EV) / CPI
EAC = AC + (BAC - EV) / CPI
Use when: Current CPI represents future performance.
A variation of Method 1, explicitly showing actual costs spent plus remaining
work adjusted by CPI.
Method 4: EAC = AC + (BAC - EV) / (CPI x SPI) (Combined)
EAC = AC + (BAC - EV) / (CPI x SPI)
Use when: Both cost and schedule performance impact
future work. Most conservative estimate when schedule delays affect costs.
Pro Tip: The EAC forecast method can only be selected from the Earned Value tab on the Dashboard. Once selected, use the EAC method selector at the top of the report to instantly recalculate all metrics, charts, and forecasts. The AI summaries update automatically to reflect your selected method.
AI-Powered
Analysis
Each section of the EVM Report includes an AI Analysis box that
provides:
1.
Observation: What the current metrics indicate about
project health
2.
Selected
Method Context:
How your chosen EAC method affects the forecast
3.
Recommendation: Specific action items based on performance
trends
Example AI summary for the Project Health
section:
"Project health assessment using EAC = BAC / CPI
forecasting indicates marginal cost performance (CPI: 0.94) and favorable
schedule performance (SPI: 1.02). The current EAC forecast of $1.28M suggests a
Variance at Completion (VAC) of -$78K. Recommendation:
Focus on cost containment measures; review procurement and labor
efficiency."

How to Generate
the Report
1.
Upload
your project file
to Nahla (XER, XML, or Excel)
2.
Navigate
to the AI Analysis
page
3.
Type
"Show earned value
report" or "Generate
EVM analysis"
4.
View
the comprehensive report with all sections
5.
Use
the EAC method selector
to compare forecasting scenarios
6.
Add
any section to your Custom
Report for sharing
Note on Actual Costs: For accurate CPI and cost metrics, you
need to upload actual cost data. Without it, CPI will show as 1.0 (assumed
on-budget). See our guide on How to Add Actual
Costs.
Adding to
Shareable Reports
The entire EVM Comprehensive Report can be
added to your shareable report with one click:
1.
Click
the "+ Add to
Report" button on the report header
2.
The
full report is added to your unified report builder
3.
Navigate
to Report Preview
to see all added sections
4.
Click
"Generate
Shareable Link" to create a public URL
5.
Share
with stakeholders who can view without logging in
Best Practice: Export your EVM report weekly or at major
milestones to track performance trends over time. Compare EAC projections
between reports to validate forecasting accuracy.
