Gantt’s idea with the chart was that other supervisors quickly could know if the production was on time, ahead or behind schedule [4]. During the First Word War an early version of the Gantt chart was used, and later in the 1930s the chart was used to major constructions projects, were it was used on the Hoover Dam and on the interstat higway network in the 1950s <ref name=WikiGantt />. | Gantt’s idea with the chart was that other supervisors quickly could know if the production was on time, ahead or behind schedule [4].

A Gant chart is a graphical representation of a project, which have been developed and named after Henry Laurence Gantt (1861-1919), American engineer. In a complex project, it may be an advantage to illustrate the schedule of the project elements as a function of time. This will help the managers to understand task relationships and they will be able to look farther ahead to ensure that everything is going as planned. In the beginning of a project the project plan has to be made, when the managers uses a Gantt chart it help them to break down the structure of the project, which later, when the chart is made, will help the managers to see the critical path. Then the critical path or paths are located the managers can put in important deadlines or milestones.
This article will shortly describe what a Gantt chart is and how to create one; furthermore, the focus will be on how to use the Gantt chart in the project, and the challenges there could be. In the end, the article will describe some of the benefits and limitations there are when using a Gantt chart in project management.
Big idea
What is a Gantt chart
A Gant chart is a graphical way of showing tasks displayed against time, on the left of the chart, the tasks are listed and along the top of the chart, the time scale is shown. A bar placed under the timeline, is indicating the start date, duration and end date of every task, by it position. A simple example of a Gantt chart is given in figure 1. This will easily give the user an overview of what tasks there are, and when they starts and ends. Furthermore, overlaps between tasks is easy to locate, and then give the manager an idea of what comes next and if tasks can be relocated [1].
Short history
In 1896 the polish economist, engineer and management researcher Karol Adamiecki (1866 – 1933) developed a tool very similar to the Gantt chart, Adamiecki published his work in 1931 but only in polish. chart in the beginning of the 20th century, 15 years later then Adamiecki’s first version, the American engineer Henry Laurence Gantt developed his own version of the Gantt chart. Gantt’s work was produced in a language more accessible to the western industry, and he became the known for it and laid name for the chart [2] Cite error: Closing </ref> missing for <ref> tag
