Define network analysis as a project management technique.

Network analysis is a project management technique that identifies the sequence of activities, their dependencies, and the minimum time required to complete a project.

How are activities represented in network diagrams?

Activities are represented with their duration, and arrows or nodes show the logical sequence in which activities must be completed.

When interpreting a network diagram, how do you identify predecessor activities?

By examining the arrows or connections leading into each activity node, which show which tasks must be completed before that activity can begin.

What does calculating time for different paths through a network diagram involve?

It involves adding up the durations of all activities along each possible route from start to finish to determine how long each path takes.

How would you amend a network diagram when an activity's duration changes?

Update the duration shown for that activity and recalculate the times for all subsequent activities and paths affected by the change.
