Project Duration

The project duration is the longest path value through the activity DAG. For this pinned project, the terminal earliest finish is the exact duration. This is the first major CPM interpretation: a schedule length is not guessed; it is forced by the dependency chain that takes longest.

highlighted = computed this step

Terminal finish

Activity F finishes at 11. Why: F is the terminal activity in this pinned project DAG. Interpretation: the terminal earliest finish is the first time all required modeled work can be complete.

Project duration

The project duration is 11. Why: CPM duration is the latest earliest finish among terminal activities. In this project there is one terminal activity, so F's earliest finish pins the duration.

No rounding

The duration stays 11. Why: all durations are exact integers, so no decimal approximation is needed. The schedule is a longest-path calculation over exact durations.

Diagram note

The table is recomputed from the DAG; it is not authored as a schedule guess. It proves what follows from the pinned model, not whether the pinned durations are good estimates. Pixel positions are rounded for layout; every number shown is exact.
