3.1 Network analysis

Network analysis is used to analyse the inter-relationships between the tasks
identified by the work breakdown structure and to define the dependencies of each
task.

relationships and dependencies.

3.2 The network diagram

 The diagram is made up of two parts: activity lines and nodes.

NAME OF ACTIVITY

DURATION
