Note (1) the critical path is in red, (2) the slack is the black lines connected to non-critical activities, (3) since Saturday and Sunday are not work days and are thus excluded from the schedule, some bars on the Gantt chart are longer if they cut through a weekend. Once this step is complete, one can draw a Gantt chart or a network diagram.ДЄ Gantt chart created using Microsoft Project (MSP). The expected time ( T E) is estimated using the beta probability distribution for the time estimates, using the formula ( OВ +В 4 MВ + P)В Г·В 6. Additionally, each task has three time estimates: the optimistic time estimate ( O), the most likely or normal time estimate ( M), and the pessimistic time estimate ( P). Some tasks can be done concurrently ( a and b) while others cannot be done until their predecessor task is complete ( c and d cannot begin until a is complete). In the following tables there are seven tasks, labeled a through g. In 1999, Gantt charts were identified as 'one of the most widely used management tools for project scheduling and control'.

By 2012, almost all Gantt charts were made by software which can easily adjust to schedule changes. With the advent of the Internet and increased collaboration over networks at the end of the 1990s, Gantt charts became a common feature of web-based applications, including collaborative groupware. The first desktop applications were intended mainly for project managers and project schedulers. In the 1980s, personal computers allowed widespread creation of complex and elaborate Gantt charts. They were used in developing the First Five Year Plan, supplying Russian translations to explain their use. Gantt's collaborator Walter Polakov introduced Gantt charts to the Soviet Union in 1929 when he was working for the Supreme Soviet of the National Economy. For many years, project managers used pieces of paper or blocks for Gantt chart bars so they could be adjusted as needed. The earliest Gantt charts were drawn on paper and therefore had to be redrawn entirely in order to adjust to schedule changes. One of the first major applications of Gantt charts was by the United States during World War I, at the instigation of General William Crozier. Gantt also frequently included graphics and other visual indicators in his charts to track performance. He designed this visualization tool to more easily measure productivity levels of employees and gauge which employees were under- or over-performing. Gantt originally created his tool for systematic, routine operations. The chart is named after Henry Gantt (1861вЂ“1919), who designed his chart around the years 1910вЂ“1915. These were also static representations of a planned schedule. Unlike later Gantt charts, SchГјrch's charts did not display interdependencies, leaving them to be inferred by the reader. The prior development leading to SchГјrch's work is unknown. It appears that SchГјrch's charts were not notable but rather routine in Germany at the time they were published. In 1912, Hermann SchГјrch published what would be considered Gantt charts while discussing a construction project. Adamiecki did not publish his chart until 1931, however, and only in Polish, which limited both its adoption and recognition of his authorship. The first known tool of this type was developed in 1896 by Karol Adamiecki, who called it a harmonogram. Historical development ДЄlthough widely used in project planning in the present day, Gantt charts were considered revolutionary when introduced. This method maximizes the float time available for all tasks. Gantt charts are usually created initially using an early start time approach, where each task is scheduled to start immediately when its prerequisites are complete. Gantt charts are sometimes equated with bar charts. Gantt charts can be used to show current schedule status using percent-complete shadings and a vertical 'TODAY' line. Modern Gantt charts also show the dependency (i.e., precedence network) relationships between activities. Terminal elements and summary elements constitute the work breakdown structure of the project.

Gantt charts illustrate the start and finish dates of the terminal elements and summary elements of a project. The width of the horizontal bars in the graph shows the duration of each activity. This chart lists the tasks to be performed on the vertical axis, and time intervals on the horizontal axis. A Gantt chart is a type of bar chart that illustrates a project schedule.
