Yes, I agree with this statement, this illustrate the powerful of using GANTT to organize the project schedule activities by illustrate the start and finish dates of the terminal elements and summary elements of these activities.

I agree, I believe HL Gantt was his time way, way ahead

A Gantt chart is a type of bar chart, first developed by Karol Adamiecki in1896, and independently by Henry Gantt in the1910s, that illustrates a project schedule. Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project. Terminal elements and summary elements comprise the work breakdown structure of the project. Modern Gantt charts also show the dependency (i.e., precedence network) relationships between activities.

Thanks for invitation Mr. Yaqoob. I agree with this statement and support to Answers of the Experts.

A Gantt chart is a timeline view that makes it easy to see how a project is tracking. You can visualize project tasks and see how they relate to each other as projects progress over time.

I agree with experts, that Gantt chart is easy and suitable tool for a sampel proect ,but

for scheduling and tracking a project with handeds of activities we need more then Gantt or bar chart we have to use another tool likes network or CPM thanks
