However, for a project management network diagram, this is a good first step into network diagramming. - Hygger. A box (also called a node) represents each task, and a line connecting two boxes represents the dependency between two tasks. It is used to determine the critical path, as well as the float of each task. Network diagram problems 1. You will start with a WBS (see Guided Project: Creating a WBS, for how to create one), and decompose the work packages (lowest elements in the WBS) into the necessary activities. Step 1: Draw a Network Diagram Task 1, 4 days Task 2, 5 days Task 3, 3 days Task 4, 7 days Task 5, 4 days 0 4 4 9 14 18 4 7 147 Task 5 is dependent on Task 2 and Task 4 being complete. It is very imperative to develop the Network Diagram before proceeding on the project work. What is Critical Path Method For in Project Management?
