Project Network Diagram: How to Draw One

Quick answer

A network diagram shows tasks and dependencies as boxes and arrows — the map that reveals the critical path; the schedule’s skeleton drawn.

The structure

Nodes = tasks (with durations), arrows = dependencies — the project’s logic drawn out.

Building it

List tasks, sequence them (what must precede what), add durations — the diagram is the calculation.

Finding the critical path

The longest path through — the chain that sets the project length.

Vs Gantt

Network shows logic; Gantt shows timing — same schedule, different views.

Bottom line

A network diagram shows tasks and dependencies as boxes and arrows — the map that reveals the critical path; the schedule’s skeleton drawn.
