Managers can see the amount of time each process takes and designate resources accordingly.īoth the Waterfall and Agile project management methodologies make use of Gantt charts. Project planners can coordinate resource allocation with the project schedule. Managers can set deadlines, milestones and schedules for various project components. The charts also show which goals were met on schedule, helping managers gauge employee productivity. Project managers can see if individual tasks are completed on time and adjust the project schedule. This is valuable information to have when managing projects for the following reasons: They show the order in which they tasks should be done and the time needed to complete them. They present in one chart all the tasks in a project. Gantt charts are one of the many project management tools. Today, Gantt charts are widely used as part of project management software. They also made the charts easier to change and suitable for more applications. Computers enabled more complex Gantt charts. Until the 1980s, Gantt charts were limited in complexity and were hand-drawn. Some of the earliest ones were used in World War I at munitions manufacturing plants to help manage the unprecedented production requirements to support war efforts. It was also useful for gauging employee productivity.Įarly Gantt charts were made of physical materials like paper and blocks. The Gantt chart became popular as a way to describe resource loading and production planning in factories. Gantt used Adamiecki's harmonogram as inspiration for his own chart. It was not published until 1931 and was only published in Polish.
It emphasizes the importance of good teams, scheduling and using compatible production tools.Īdamiecki created the harmonogram, a precursor of the Gantt chart.
He developed the law of harmony in management. Karol Adamiecki, a Polish mechanical engineer and professor, is credited with devising what would become the first Gantt chart in 1896.
