Worked Example
Verified calculation
Given:
- Earned Value = 150000
- Actual Cost = 142500
Expected Result:
- Cost Variance = 7500
Engineering Interpretation:
Under the given input conditions, the calculated result is: Cost Variance = 7500 USD.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
