Worked Example
Verified calculation
Given:
- Maximum Earliest Finish Time of Immediate Predecessors = 0
- Activity Duration = 3600
Expected Result:
- Activity Earliest Start Time = 0
Engineering Interpretation:
Under the given input conditions, the calculated result is: Activity Earliest Start Time = 0 s.
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.
