A network diagram graphically represents the relationships between activities in a project through connected arrows and boxes. There are two main types: precedence diagramming method (PDM) which focuses on logical dependencies between activities, and arrow diagramming method (ADM) which focuses on the flow and direction of activities. To create an effective network diagram, one must understand the project's purpose, propose the proper resources, connect activities based on dependencies and time elements, and ultimately produce the final network diagram model.

3. What is Network Diagram
• A network diagram is a graphical representation of a project
and is composed of a series of connected arrows and boxes to
describe the inter-relationship between the activities involved
in the project.
• A sequence of graphically proposed activities to accomplish
project.

4. Types
• Precedence diagramming method (PDM)
Precedence diagram focuses on logical dependencies and
constraints between activities
• Arrow diagramming method (ADM)
The arrow diagram focuses on the flow and direction of
activities
