Limitations of Gantt Chart
1. If the project consists of too many activities, it becomes clumsy to draw the Gantt chart. Due to this bar chart is not useful for big projects consisting of large number of complex activities.
2. The chart does not give any data about what exactly is completed and what is not as the chart does not shown events between the bars.
3. As the chart combines plan and schedule, it is difficult to known whether the activities have optional starting dates.
4.The chart does not exhibit the dependencies or inter relationship between the activities and as such it id difficult to say, what will be the effect of delay of one activity over the other or the entire project.
5. Gantt charts are not a tall useful in those projects where there are uncertainties in determination or estimation of time required for the completion of various activities.
These charts are useful for only small size conventional projects specially construction and manufacturing in which time estimates can be made with fair degree of uncertainty.
