The Gantt chart, which is widely used in project management, is one of the most popular and useful ways to showcase tasks (activities or events) that are displayed over time. To the left of the chart is a list of tasks and at the top is an appropriate time scale. Each function is represented by a bar; The position and length of the bar indicate the project schedule.
Below are the list of purpose and use of Gantt Chart
- What are the different functions?
- When each activity starts and ends
- Each task is scheduled for how long?
- When jobs combine with other jobs, and how much
- Schedule of the entire project
What is the Meaning and Definition of the Gantt Chart?
The Gantt chart is a commonly used performance indicator for a project plan. It is a type of bar chart that shows the start and end dates of project items such as resources, planning and dependencies.
How did the Gantt Chart get its name?
The Gantt chart was discovered by Henry Gantt (1861-1919) who was an American engineer who designed the Gantt chart. That is why he got his name Gantt Chart.
The Origin of the Gantt Chart
In the late 1800’s, Polish engineer Carol Adamiecki developed a visual flow chart called the “harmonogram.”
About the year 1910, Henry Gantt, chief consultant and engineer, took Adamiecki’s idea to the next level. His chart is designed to help managers see if their work is done, before or after, and builds the foundation of the tool we use today.
Understanding the Gantt Charts
The Gantt chart is the most widely used chart in project management. These charts help to plan the project and define the sequence of tasks that need to be completed. In most cases, the chart is displayed as a horizontal bar chart.
Horizontal bars of different lengths represent a project timeline, which can include sequence of tasks, length of time, and start and end dates for each project. The horizontal bar also shows how much work needs to be completed.
The Project chart helps to plan, manage, and monitor specific tasks and resources in a project. The chart shows the timeline of the project, which includes scheduled and completed work over a period of time. The Gantt chart assists project managers in communicating project status or plans and also helps ensure that the project stays on track.
Benefits of the Gantt Chart
The chart identifies tasks that can be performed similarly to those that cannot be started or completed until the other tasks are finished. It can be helpful to identify potential issues and identify activities that may be excluded from the project timeline.
Example Gantt Chart
If a project is about installing new software on a server. The project tasks that need to be completed do a research, select a software product, test the software, and then quit. The highlight of choosing software. These functions appear as vertical lines in a chart.
It says the duration of the project is 40 days. Each task takes 10 days to complete, and each task depends on the previous task. The critical task is to test the software in the areas of development and testing. Dates and end dates, duration, and historical symbols appear as horizontal bars. The percentage of work completed per project is also indicated in the horizontal bars.
Use of Gantt charts?
Gantt charts help visualize the various activities and projects that occur simultaneously with the organization, and how well they have progressed. Project Charts are used by management to plan and organize such projects so that resources are allocated appropriately. That priority projects are completed before they start to become less important.
Who was Henry Gantt?
Henry Gantt was a social scientist and administrative adviser who also held a degree in mechanical engineering. He has worked in the field of scientific management, devising ways to reduce and increase the productivity of companies and their employees. He developed the Gantt chart in the 1910s to help managers understand the progress of their employees and to ensure that jobs were up to date.
What are the components of the Gantt Chart?
A Gantt chart can vary in complexity and depth, but it will always have three important elements:
- What project or work to be performed by Gantt Chart;
- Operating near the y-axis;
- Phases or stages of progress shown on the x-axis (either top or bottom chart);
and progress barriers, identified as direct barriers, indicating how far each project is from any location.
