The Project's Network Diagram

The document discusses network diagrams, which are schematics that show the logical relationships between activities in a project. It notes that network diagrams were developed in 1957 by the US Navy and Lockheed to reduce the development time of the Polaris project by 45%. There are two main types: activity-on-arrow (AOA) diagrams and activity-on-node (AON) diagrams. AOA shows activities as arrows between initial and final states, while AON shows activities on nodes connected by arrows. The network diagram must have a starting point, end point, and show all predecessors and successors of activities without loops.
