WHAT IS GANTT CHART?

Gantt chart is a type of bar chart. In which a series of horizontal lines shows the amount of work done or production completed in certain period of time in relation to the amount planned for those period.

PURPOSE OF GANTT CHART

•To illustrate the relationship between project activities and time.•To show the multiple project activities on one chart.•To provide a simple & easy to understand representation of project scheduling.

STEPS TO CREATE A GANTT CHART:

Determine project start date and deadline.

Gather all information surrounding the list of activities within a project.

Determine how long each activities will take.

Evaluate what activities are dependant on others.

Create a graph shell including the timeline and list of activities.

ACTIVITY PREDECESSOR

EXPECTED TIME

A - 4B - 5.33C A 5.17D A 6.33E B,C 5.17F D 4.50G E 5.17

ADVANTAGES:A useful tool for displaying time-based

information within a project.Very simple to create.They provide a useful overview of project

activities, a good starting point for project planning.

The charts are widely used and understood.There exists several PC software packages

that allow you to build Gantt charts.

LIMITATIONS:It does not explain the reasoning behind the chosen duration of each activity.

It is very difficult to update when changes to the project plan take place.

As gantt charts are difficult to update manually, they can often become obsolete.

The charts do not consider project costs or resources.

•Gantt charts were employed on major infrastructure projects including the Hoover Dam and Interstate highway system and continue to be an important tool in project management and program management.
