GANTT Chart in Operating System | OS Tutorials

In an operating system, a Gantt chart is a horizontal bar chart developed as a production control tool in 1917 by Henry L. Gantt, an American engineer and Social Scientist. Frequently used in project management, a Gantt chart provides a graphical illustration that helps to plan, coordinate, and track specific tasks in a project.

• A Gantt chart is constructed with a horizontal axis representing the total time span of the project, broken down into increments (for example, days, weeks, or months), and a vertical axis.
• Horizontal bars of varying lengths represent the sequences, timing, and time span for each task.
• Gantt charts give a clear illustration of project status, but one problem with them is that they don’t indicate task dependencies.
• The PERT chart, another popular project management charting method, is designed to do this. Automated Gantt charts store more information about tasks, such as the individuals assigned to specific tasks, and notes about the procedures.
• They also offer the benefit of being easy to change, which is helpful. Charts may be adjusted frequently to reflect the actual status of project tasks as, almost inevitably, they diverge from the original plan.
