What is a network diagram?
What is a network diagram?
Visual tool showing tasks needed to complete a project
How are activities shown in network diagrams?
How are activities shown in network diagrams?
As labelled arrows (edges), not as points/vertices
What is an immediate predecessor?
What is an immediate predecessor?
Activity that must finish before another can start
What does '—' mean in an activity chart?
What does '—' mean in an activity chart?
No immediate predecessors; can start right away
Rule 1: Which activities start from start vertex?
Rule 1: Which activities start from start vertex?
Activities with no immediate predecessors
Rule 2: Which activities lead to finish vertex?
Rule 2: Which activities lead to finish vertex?
Activities not immediate predecessors for any other
Method 1 for constructing network diagrams
Method 1 for constructing network diagrams
Build from start to finish (forward construction)
Method 2 for constructing network diagrams
Method 2 for constructing network diagrams
Build from finish to start (backward construction)
What is branching in network diagrams?
What is branching in network diagrams?
Multiple activities share same immediate predecessor
What is converging in network diagrams?
What is converging in network diagrams?
Multiple activities are predecessors for same activity
