Gantt Charts
One particularly effective way of showing the key information from a project net-
work is the Gannt chart. A Gantt chart is a visual presentation of some of the
information from Table 9.2. The Gantt chart for the Souk al Bustan Shopping
Centre project is shown in Figure 9.8. The chart shows the project activities on the
vertical axis and the project duration on the horizontal timescale. A bar is used for
each individual activity with the bar starting at that activity’s ES time and ending at
the activity’s EF time. If there is slack time associated with that activity, this is shown
