Ans :
A Gantt chart is a horizontal bar or line chart which will commonly include the following
features:
• Activities identified on the left hand side.
Time scale is drawn on the top (or bottom) of the chart .
• A horizontal open oblong or a line is drawn against each activity indicating
estimated duration.
• Dependencies between activities are shown.
• At a review point the oblongs are shaded to represent the actual time spent
(an alternative is to represent actual and estimated by 2 separate lines).
• A Verticals cursor (such as a transparent ruler) placed at the review point
makes it possible to establish activities which are behind or ahead of
schedule.
