Project, objectives, tasks and activities are
now defined but:
- Need to define PRECEDENCE RELATIONSHIPS of the
Questions to ask:
- Which activities are you going to start with?
- Which need to
wait for the completion of another?
- Which tasks need to be completed
The sequencing of activities are influenced by:
- Technical requirements
- Availability of resources
Each activity is assigned a number, and time is plotted along
the horizontal axis. This kind of chart was developed by Henry
Gantt during WWI.
Gantt Charts are useful because:
- Indicate the status of each activity
- Allow tracking of progress.
- Allow for what–if analysis
- Can be drawn to show budgets,
needed resources, and equipment usage instead of activities.
However Gantt Charts:
- do not show precedence relationships
- are at times tedious to update
Example of a Gantt Chart:
Task Name Week Number
6 7 8 9 10 11
