What is a Bar/Gantt Chart
- Gantt Chart is a simple bar chart
- was introduced by Henry Gantt around 1910 – 1915
- Simply method to illustrates a project schedule
- a common technique to represent the phases and activities of WBS
- Illustrates the relationship between project activities & time
- Can show the multiple project activities on one chart
- Provides a simple & easy way to understand activities and timing

Bar/Gantt Chart
- The bars in rows represent the corresponding task
- Horizontal positions indicate start and end points of a task
- Bar length denotes the duration of an activity
- Easy to compare task durations
- can be resources allocated
- Precedence relationships can be represented using arrows
- Critical activities are usually highlighted
- Graphical representation variation in activities

Two methods
1. Forward Schedule: Starting the chart with a given start date and moving forward until the given deadline
2. Backward Schedule: Starting with the final deadline and logically working backwards to find the start date.

Methods

Step by Step
Identify start date and end date.
Create WBS and activities
Determine time required for each activity
Determine dependencies
Using either Forward or Backward Scheduling create graph indicating the timeline and list of activities.
Represent the graph
