Gantt chart

The Gantt chart is one of the most popular tools in project management. It is a graphical tool that allows for displaying the project schedule in a calendar format. It is used for planning, supervising, and monitoring the progress of work.

What does a Gantt chart look like?

A Gantt chart consists of two axes – a vertical axis and a horizontal axis. The vertical axis contains tasks or project stages, while the horizontal axis represents dates. Each task is represented by a bar, the length of which indicates the duration of that particular stage. The bars are placed in the appropriate positions on the horizontal axis, depending on the start and end dates of the task execution.

Characteristics of a chart

In a Gantt chart, dependencies between individual stages can also be taken into account. For example, if the completion of one task depends on the completion of another task, this can be indicated on the chart.

Gantt chart elements

• Task labels – each task has its name, which is placed on the vertical axis. Task labels often include task numbers or other additional information.
• Task bars – the length of the bar indicates the duration of a specific stage, and its position on the horizontal axis shows the dates when the task is performed. The bars can be of different colors or marked with special symbols to enhance the readability of the chart.
• Additionally, the chart can also include information about task dependencies. For example, arrows can indicate that the start of one task depends on the completion of another task.

What is this used for?

The Gantt chart is not only useful for planning and monitoring projects, but also for team communication. With this tool, all team members have a clear picture of the project schedule and can easily see how their work fits into the overall plan.

The history of the Gantt chart

The Gantt chart was proposed and developed by Henry Laurence Gantt in the first decade of the 20th century. Gantt was an American mechanical engineer and project management consultant. Initially, he used his visual tools for planning and monitoring work in the shipbuilding industry.

How did it start?

His first works in the field of project charts began in 1910 when he received a commission from Bethlehem Steel Company to design ships. Gantt needed a tool that would allow him to easily present a work schedule and identify dependencies between individual tasks. As a result, the so-called “Gantt chart” was created.

Development of the tool

• The first Gantt charts were manually drawn on large pieces of paper. They were simple diagrams depicting a timeline along the horizontal axis and a list of tasks and their durations along the vertical axis. Tasks were marked on the chart using rectangles, with their length representing the duration of the task.
• In the following years, the Gantt chart evolved and gained popularity. In 1917, Gantt published his work titled “Principles of Scientific Management,” in which he extensively described the creation and utilization of Gantt charts in project management. This publication contributed to the development of project management methodologies and the widespread use of Gantt charts in various industries.
• With the advancement of technology, Gantt charts started being created using computerized project management software. They took on an electronic form, allowing for the automation of the planning, monitoring, and reporting processes. As a result, Gantt charts have become even more efficient tools for project management.

Gantt chart – Applications

Gantt chart is a popular project management tool that is used in various industries and fields. It allows for visualizing the project schedule in a simple and clear way. Below are a few examples of Gantt chart applications.

IT

In the IT industry, it helps in planning and executing software development projects. It is also a valuable tool in managing construction projects, where it enables tracking the progress of work and coordinating activities between different teams.

LOGISTICS

It is also used in logistics projects, which aid in planning deliveries and transportation of goods.

MARKETING

In this field, Gantt chart is often used for planning and monitoring marketing activities such as advertising campaigns, product launches, and organizing events. It allows for better coordination of marketing activities and estimation of the duration of each project phase.

Examples of applications

• An example of using a Gantt chart could be the construction of a new company headquarters. The chart will be able to present the various stages of the project, such as building design, obtaining construction permits, foundation construction, installation assembly, and interior finishing. By utilizing a Gantt chart, it will be possible to see which tasks will be carried out simultaneously, how long each stage will take, and what dependencies exist between them.
• Another example is conference organization. A Gantt chart can be used to outline individual tasks, such as selecting a location, planning the agenda, inviting speakers, and preparing promotional materials, among others. This will allow organizers to have a comprehensive view of the entire organizational process, track progress, and easily identify any potential delays.

Applications of Gantt Chart in Production

Production planning

It allows for a graphical representation of the successive stages of the production process and determination of the schedule and deadlines for completing individual tasks. This enables managers and production staff to easily monitor progress and adjust the schedule if necessary.

Progress monitoring

By placing the start and end dates of each task on a chart, it is easy to check if the work is in line with the schedule. The Gantt chart also allows for monitoring resource availability and making necessary changes in case of delays or issues.

Task management

Thanks to a graphical representation of the schedule, managers can assign appropriate tasks to employees and determine deadlines for their completion. This way, it is easy to monitor work progress and identify any obstacles or delays.

Coordination of activities

In case of more complex production projects, a Gantt chart can be used to coordinate the activities of various groups of workers. Based on the chart, one can determine which tasks are related to each other and what dependencies exist between them. This can help in scheduling individual tasks and planning collaboration between different departments or subcontractors.
