A GANTT CHART is an effective visual PLANNING tool for DISPLAYING ACTIVITIES/TASKS/EVENTS OVER TIME. ON THE LEFT OF THE CHART is a LIST of the ACTIVITIES and ALONG THE TOP IS THE TIMESCALE. Each activity is represented by a bar; the position and length of the bar shows the start date, the duration of each activity and the end date of the activity.
This allows managers to see quickly:
WHAT the main activities are.
WHEN each activity begins and ends.
HOW LONG each activity is scheduled to last.
WHERE activities OVERLAP with other activities – these are simultaneous activities which can be ‘done together’ to save the business time in completing the project.
THE START and END DATE of the whole project. This allows the business to inform customers when the project, such as a new building, is likely to be completed.
A Gantt chart therefore shows managers what has to be done (the activities) and when (the schedule).
