Activity Sequencing and Network Diagrams
• Review activities and determine dependencies of project activities or tasks
• Determine dependencies in order to use critical path analysis
• Network diagrams are used for showing activity sequencing
• A network diagram is a schematic display of the logical relationships among, or sequencing of, project activities
![Page 11: Project Management. What is a Project? One Time Effort Identifiable Start/End Points Specific Objectives Multiple Tasks Resources from Across the Organization](https://reader035.vdocument.in/reader035/viewer/2022062714/56649d095503460f949dadad/html5/thumbnails/11.jpg)

Network Diagrams
Two popular network diagrams:
• Activity on Arrow (AOA) network diagrams or Arrow diagramming method (ADM)
• Project network diagrams or Precedence Diagram Method (PDM)

Activity on Arrow (AOA) Network Diagrams
• Also called Arrow Diagramming Method (ADM)
• A network diagram in which activities are represented by arrows
• ADM is used for scheduling activities in a project plan
• Precedence relationships between activities are represented by circles
connected by one or more arrows
• The length of the arrow represents the duration of the activity
• ADM only shows finish-to-start relationships, meaning that each activity is
completed before the successor activity starts
• Sometimes a "dummy task" is added, to represent a dependency between
tasks, which does not represent any actual activity. Such a dummy task often
has a completion time of 0

Project Network Diagrams
• Also called Precedence Diagram Method (PDM)
• A visual representation technique that depicts the activities involved in a project
• Communicate the flow of project execution
• Identify missing activities: When an activity is not identified, it’ll never be done.
• Identify dependencies: Each activity is dependent on some other activity. When a dependency is not identified, the project will be delayed until such a time that identification occurs
• Identify critical activities: Certain activities have a greater impact on project schedule than others. This is known as the Critical Path Method (CPM)
• Create a project schedule: The final goal is to create a practical and robust project schedule.

Project Network Diagrams• Task Dependency types

Gantt Charts• Gantt charts provide a standard format for displaying project
schedule information by listing project activities and their corresponding start and finish dates in a calendar format
• Symbols include:
– Black diamonds: Milestones
– Thick black bars: Summary tasks
– Lighter horizontal bars: Durations of tasks
– Arrows: Dependencies between tasks

Milestones of Gantt Charts• Milestones emphasize accomplishments for large projects• Create milestone by entering tasks that have a zero duration
![Page 21: Project Management. What is a Project? One Time Effort Identifiable Start/End Points Specific Objectives Multiple Tasks Resources from Across the Organization](https://reader035.vdocument.in/reader035/viewer/2022062714/56649d095503460f949dadad/html5/thumbnails/21.jpg)

Critical Path Method (CPM)• CPM is to predict total project duration
• A critical path for a project is the series of activities that determines the earliest time by which the project can be completed.
• The critical path is the longest path through the network diagram and has the least amount of slack or float
• Slack or float is the amount of time an activity can be delayed without delaying a succeeding activity or the project finish date

Critical Path Method (CPM)• Three main techniques for shortening schedules:
– Shortening the duration of critical activities or tasks by adding more resources or changing their scope
– Crashing activities by obtaining the greatest amount of schedule compression for the least incremental cost
– Fast tracking activities by doing them in parallel or overlapping them
