The Ultimate Guide to Gantt Charts: Everything about the Tool You Can’t Ignore for Project Planning

A Gantt chart is a great tool for task management, project planning, scheduling, and progress tracking.

In case you have questions about these diagrams, here is the complete guide to Gantt charts that covers most of them.

As you see, with a Gantt chart, you will know what work has to be done, current work as well as what has already been accomplished. It also helps keep track of the progress of your plan or project and be aware of all the deadlines in advance.

The history of a Gantt chart

The “Gantt” in this expression stands for the last name of its creator – Henry Gantt, an American mechanical engineer, and management consultant. He designed a diagram and further published articles about his invention in 1910 and 1915. At that time, those charts were completely novel.

Surprisingly, but a diagram itself was introduced even earlier, in 1896, by Karol Adamiecki, a Polish economist, engineer, and management researcher. However, he only managed to publish his first work in 1909. Later on, in 1931, he published a more widely known article where he described the harmonogram – he called the chart like this.

The reason why the Gantt chart is named after the American engineer and not the Polish one is quite obvious. Henry Gantt spoke and wrote in English, while Karol Adamiecki published his articles in Polish and Russian.

The history of a Gantt chart in a few dates:

  • 1896: Karol Adamiecki designs a means of displaying interdependent processes. He calls it a harmonogram.
  • 1903: Henry Gantt defines a chart to increase the visibility of production schedules.
  • 1903: Adamiecki’s invention causes a stir in technical circles in Russia.
  • 1909: Adamiecki publishes some articles in Polish describing the diagram.
  • 1910-1915: Henry Gantt further develops the diagram, publishes articles describing them, and popularizes them.
  • 1931: Adamiecki publishes his more known article about the harmonogram in Polish and Russian.
  • Today: a Gantt chart is one of the most popular tools in project management.

What is a Gantt chart used for?

A Gantt chart is used to cover several project management issues. However, one of them is fundamental.

The purpose of a Gantt chart is scheduling.

With its help, you can easily schedule every phase of a plan regardless of its duration with clearly defined start and end dates.

In addition, a Gantt chart helps identify milestones – significant events in your projects with no duration – and deadlines. Don’t want to miss a date? The Gantt diagram is your solution!

With the advance of online Gantt chart software, the chart becomes a handler in other situations. In particular, it helps manage resources, cost, and collaborate between team members.

Put it shortly, a Gantt chart is used for:

  • Task scheduling.
  • Identifying milestones.
  • Keeping track of deadlines.
  • Keeping track of progress.
  • Connecting tasks with dependencies.
  • Collaboration.
  • Resource management.
  • Cost management.

What information is included in a Gantt chart?

A typical Gantt chart should include the following information:

  • Tasks, their duration, status, and priority.
  • Start and end dates.
  • Progress.
  • Timeline with the time scale.
  • Milestones.
  • Dependencies between tasks.
  • Deadlines.
  • Critical path.

A robust Gantt chart tool that is able to cover most of the needs of project managers will also include:

  • Assignees.
  • Estimations.
  • Resource workload: who works on what tasks, who is overloaded, who can be given more tasks.
  • Costs.
  • Options that allow customizing plans.
  • Comments, attachments, notifications for teamwork.
  • Baselines.
  • Templates.
  • Auto scheduling.

So, if you need an answer to the question “What are the main features of a Gantt chart?”, just look above – these features help build solid projects and organize all the teamwork.

In general, you need to follow four simple steps in order to create a Gantt chart:

  • Add tasks.
  • Define dates for tasks and the whole calendar.
  • Connect tasks with dependencies.
  • Assign tasks.

Advantages and disadvantages of a Gantt chart

It is highly likely that now you think something like “Wow, what a great tool it is! Aren’t there any disadvantages?”

As anything in our world, a Gantt chart is reviewed from different perspectives.

What are the advantages of a Gantt chart?

  • It is transparent, clear, and structured

Imagine that you need to promote your brand to increase sales volume. You will probably be scared from the very beginning as it is difficult to define where to start and how to measure deliverables.

A Gantt chart allows breaking down projects into smaller pieces that can take from a few hours to a few days. The more you chunk, the higher the chances are to complete a project as each task is clearly defined. This is a critical advantage of a Gantt chart in project management.

  • It allows connecting tasks

You hardly find a project where tasks exist separately from each other. Usually, they are presented in certain orders. For example, a finish date of one task gives a start to the other.

In a Gantt chart tool, you can easily connect tasks with dependencies to show the relationship between them.

Let’s take an example.

You need to plant a tree. With the help of the diagram, you will be able to connect interdependent phases.

Dig a hole place a tree straighten it if needed fill the hole carefully handle it if needed.

This consequence of events shows that you can’t start with the last action as it is dependent on the previous ones.

  • It can be shared for presentation

Robust Gantt chart solutions provide with the Sharing and Export features as one of the benefits. They allow showcasing plans, current or any other states of a project to anyone outside your team: stakeholders, clients, customers, etc.

  • It keeps motivation and focus

Once a project plan is ready, this becomes a point of reference for you and your team in case you manage a team project. This is like the single source of truth that helps to avoid a project scope creep.

Also, some people work more efficiently when they have everything structured in one place and where the progress, goals, and results are shown with a clear focus and no ambiguity. And remember about resource allocation: it will keep project participants motivated as the tasks assigned to them are clearly defined.

  • It is good for collaboration

Team projects can’t exist without collaboration. Forget about success if there is no collaboration in your schedule.

A cutting-edge Gantt chart generator is no longer a place for tasks and dates. It is far more than that. Tasks always need to be commented and attached with necessary documents as well as project participants need to be constantly notified about assignments, deadlines, and other updates.

A Gantt diagram can become a hub for all project-related information and communication.

  • It allows allocating resources properly

Without resources, one can hardly imagine a project. Those resources can be real or virtual and they need to be properly managed.

The resource workload feature helps managers avoid situations when some resources are overloaded and some are free for performing tasks.

Proper allocation leads to proper budget management.

  • It shows the critical path

A critical path is a feature that shows the connection of the most important tasks needed for a project to be timely completed. If one task from the critical path is delayed, the whole project will be delayed too.

GanttPRO is online Gantt chart software that helps thousands of individuals and teams manage their tasks, deadlines, resources, and costs. Great for communication and collaboration on a project.

Disadvantages of using Gantt charts

  • No place for uncertainty

One of the core limitations of a Gantt chart is that it perfectly serves for projects where all the tasks, milestones, deliverables, and dates are known from the start – all in all, this is how the Work Breakdown structure works.

However, this is not the dead end. Efficient Gantt chart creators allow making adjustments at any moment of project development. The Auto scheduling function will change the dates of interdependent tasks automatically.

  • May not be suitable for too large projects

This is an arguable point. However, some managers find it challenging to work on long-term projects of two and more years with the help of a Gantt chart. They say that adding new tasks and resources to a plan will force you to constantly scroll up and down your chart to find the item you are looking for.

However, breaking down a large project into smaller ones can turn this disadvantage into a benefit. Also, search options are at your service.

  • It needs to be constantly updated (doubtful)

Yes, projects will require time on management and updates. But what does not require it to do work?

All the work you do will take your time. However, you can make these processes shorter turning yourself into a rockstar of a certain application where you are like a duck to water.
