Gantt Chart Importance

A Gantt chart is also known as bar chart represents a project plan by making each task into a bar and putting those bars into a time schedule.

We can define a Gantt Chart as a bar chart that helps to understand through, a monitor, and track project progress in terms of activities on the Y-axis & durations at the X-axis.

Some people also refer a Gantt chart as Activity Chart & some even call it a Milestone chart!

Brief History of Gantt Charts

As the name suggests that it might be the sole work of Mr. Henry Gantt, but we have some fascinating history and a lesson learned.

 Gantt Chart was introduced by Henry Gantt? – No! 

This Chart tool was first developed Karol Adamiecki in 1896, he called it as harmonogram. But he did not publish but later on, he did in 1931 but in Polish language & hence could not get adoption and due recognition.

Then again in 1912, Hermann Schürch while discussing a construction project published in Germany but these charts were without interdependencies, and although this type of work was common in Germany back then.

Henry Gantt (1861–1919), who designed his chart around the years 1910–1915. These are now considered the most powerful planning and tracking tool of a project. That is why this chart is called henry Gantt after his name. (

The Gantt chart we see and use today was improved along with task dependencies by Wallace ClarkHe used to work in Henry’s firm and was considered as Henry Gantt’s disciple.

The lesson learned is that if you got a great idea then make sure to publish it immediately and in English! (Respect for all other languages but English is a global language)

How to create a Gantt Chart

Gantt charts can be created on a number of software nowadays. Some are simple others are fancy. But the main purpose of a Gantt chart to display the information of a Project in a visual manner.

Here, you can see activities are plotted and Y-axis and following the time as per dependencies pattern.

We also call it a Milestone Chart as sometimes we only display Milestones to report to top management for any big project. A milestone report is a top-level report that will display the Milestones to be achieved with time. Although a milestone is an event with a zero duration still it will show on a different period of time.
