Top 7 Benefits of Gantt Charts in Project Management

Just imagine how difficult it is to juggle numerous balls at once. You miss a ball and the entire act is gone for a toss. Project management is quite similar to juggling where you are constantly ‘juggling’ between multiple tasks, people, projects and what not. The moment you miss a deadline, the entire planning can go haywire and have serious repercussions.

This is why it’s helpful to have a visual overview of a project schedule and know when is each activity completing and who is working on it. And, this is where Gantt charts come into the picture.

Not just project managers, in fact, people from all walks of life are now using them to plan, organize, and deliver. If you always wanted to learn what Gantt charts are and how you can be benefited from them, you’ve come to the right place. Before jumping straightaway to its benefits, let’s first understand what they really are:

What is a Gantt chart?

According to Wikipedia, “A Gantt chart is a type of bar chart that illustrates a project schedule and shows the dependency relationships between activities and current schedule status.”

In simpler words, Gantt charts are a visual view of tasks displayed against time. They represent critical information such as who is assigned to what, duration of tasks, and overlapping activities in a project. All in all, Gantt charts are the perfect allies for planning, scheduling, and managing a project.

History and evolution of Gantt charts

Gantt charts have an interesting history that needs to be shared. The origin of the tool dates back to the late 1800s when a Polish engineer Karol Adamiecki invented a diagram called harmonograph. The major reason behind inventing this diagram was to improve the way production schedules were displayed during that point of time. The only problem was that all findings and other critical information were published in Polish and Russian only.

Meanwhile, Henry Laurence Gantt, a management consultant and an engineer, was also working on the similar concept around 1910. He designed a chart to help manufacturing managers to easily visualize their work schedule. With time, it underwent some changes and evolved into Gantt charts. Therefore Henry Gantt is considered the inventor of Gantt Chart (hence the name).

Since we have revisited what Gantt charts are and how they got popularized, it’s time that we discuss how online Gantt charts make project management better.

Top 7 benefits that Gantt charts offer:

1. Know what’s going on in your projects

The biggest advantage of using free online Gantt charts in project management is that you get to see everything related to project at a single place. It acts as a great visualization and prioritization tool as it provides the total overview of the project and tells you about the critical information such as members involved in each step, the order of tasks, duration, start-to-end dates, task dependencies and progress made in them. Hence, online Gantt charts are helpful in equipping project managers with the information they need to oversee while managing projects.

2. Improved communication and team cohesion

Communication is an integral part of a project that can make or break it. In fact, 86% of employees feel lack of communication as the biggest reason for workplace failures. On the other hand, Gantt charts are known to provide crystal clear communication. Project managers can use these charts to know who is working on what and give inputs on certain tasks and pass relevant information to them. This helps him to communicate better with team members and also improves their relationship as a team. Most importantly, it eliminates the need for having a separate tool for tracking and communication purposes.

3. Avoid resource overload

Too many problems arise when resources are stretched over too many tasks and processes. Gantt charts allow you to use your resources effectively as you get to see a project’s timeline where you can easily see how and where resources are being utilized. Within Gantt charts, you can also delegate tasks and align resources without burdening them with too much work. This way you can effectively manage resources and when resources are properly managed, projects are more likely to be completed within budget and deadlines.

4. Measure the progress of projects

Once you schedule your project in a Gantt chart software you can check the progress of the projects in it. The feature to measure a project’s progress enables you to make changes in your strategy if it is lagging behind its schedule. As project members can update the completed percent of each task, everyone stays on the same page. This information is quite useful to determine if the project is headed in the right direction or not.

5. See overlapping activities and task dependencies

At times, you cannot start a certain task unless another task which is dependent on the former is completed. Such task dependencies can make things difficult to be managed especially in case of complex projects that have too many tasks. As you get to see an overview of projects in a Gantt chart software, you can easily see which tasks are dependent on each other and schedule them in a way that they don’t impact the overall progress in any way and team members share equal responsibility.

6. More clarity

It’s not a good feeling when you get stuck in a project and you don’t know where things are going. Although it’s quite common to get stuck while working on a project, however, Gantt charts let you see things with a lot more clarity with just a click. As you can instantly see the progress of tasks, it helps you and others working on a project to develop a better understanding of how things are unfolding. More clarity means better understanding which further leads to successful completion of a project.

7. Better time management

Many project managers pitch scheduling as one of the biggest benefits of Gantt charts in project management. As time plays an important role in the life of a project, therefore a Gantt chart software helps project members to understand the severity of time delays while managing projects. It’s easy to get carried away and work mindlessly on tasks but when you have a unified view of the overall progress, you can easily allocate time to each and every task and do what really needs to be done.

Application of Gantt charts

The sheer simplicity and ease-of-access of all relevant information make Gantt charts an ideal choice for teams to use them for organizing their schedules. Due to this, Gantt charts are widely used in project management, IT and development teams. Apart from them, marketing, engineering, product launch, manufacturing teams can also use Gantt charts to get an overview of how things are rolling on the work front.

How to make the right choice?

With so many tools claiming to be the ‘right Gantt chart software’, it can be hard to make the final choice. Before you select a tool in haste, make sure it allows you to do the following things:

  • Share project information with others
  • Collaborate in real-time
  • Easy drag-and-drop for efficient scheduling
  • Import, export, and integrable with third-party applications
