Project Management Gantt Chart Guide


Most project managers, especially in software development, are aware of Gantt charts. It is one of the most popular projects management tools. Project Gantt Chart help improve productivity and efficiency in workflows and ensure that tasks are completed on time. Such scheduling charts can be applied to small projects and the most complex ones. The basics of Gantt's chart are fairly easy to understand. So, what are the secrets of the schedules developed by Henry Gantt? From this article, you will immediately understand what is Gantt charts and what they are for.

What is a Gantt chart?

The Gantt chart is a planning and task management tool invented by American engineer Henry Gantt. It looks like horizontal bars located between two axes: a list of tasks vertically and dates horizontally. Gantt planning charts are widely used for planning projects of all sizes in different industries and areas. The Gantt diagram shows not only the tasks themselves but also their sequence. This is a convenient way to show what work is scheduled to be done on a specific day and time. Project plan Gantt chart is often used in an Agile environment to track the status of projects and simplify the interaction of teams in working on a project.

Each bar in the Gantt chart schedule represents a step in a process (or task in a project), and its length depicts the amount of time it takes to complete that step or task - Gantt chart timeline. This allows you not to forget anything and do everything promptly. When you zoom in to see the whole picture, Gantt charts give you an idea of what needs to be done now, as well as showing who is responsible and when. Thus, it is also a great way for project managers to control the progress of the project. All in one space.

What is the Gantt chart used for?

As was already mentioned, most modern Gantt charts are cloud-based project management software tools that help heads and teams plan projects of all sizes. These project management charts allow teams to have complete control over the project planning process and easily make the necessary adjustments. With the help of such a task chart, resources can be allocated in such a way that priority projects can be completed before less important ones begin. If a date is moved or a milestone is moved, the Gantt’s chart should automatically reflect these changes so that you always stay up to date with the latest developments in the project. In this way, it will be easier for different departments to work together most efficiently.

Thus, the Gantt chart is used for:

  1. Scheduling projects and tasks in one or several projects at once
  2. Project progress control
  3. Task prioritization
  4. Team scheduling
  5. Comparison of planned and actual project timelines
  6. Resource management
  7. Organization of complex projects
  8. Evaluation of timelines
  9. Coordination with many stakeholders

What is a Gantt chart example?

Here you can see an example of a Gantt chart on the GudHub platform. Using GudHub platform as Gantt chart software, project managers can take full control of your project, create a schedule, see how work is progressing, and save all the necessary data about it in one place.

In this Gantt chart sample, scheduled tasks are displayed vertically, and using the horizontal time axis, you can find out the duration of each of them. The time from the start of the first task to the completion of the last is the duration of the entire project. Each of the tasks is assigned to one or more performers. Also, those who have access to the document can at any time see who is working on what task, and at what stage the project is.

Switching between tabs on top, you can view different areas of the project. For example, on the page “All activities”, you have a task board with an expanded task view. Each task is arranged sequentially by date and day of the week, which you can change. You also can change the title activity by status: Assigned, In the process, Complete, Review, etc. Each status has its color. Pretty easy and understandable.

Is there a Gantt chart in Excel?

Unfortunately, Microsoft Excel does not have a built-in Gantt chart template as an option. However, you can quickly make a Gantt chart in Excel using the bar chart functionality and customizing it. The tool offers a wide range of charts of all kinds: from classic to petal histograms.

Keep in mind that although the Excel chart mimics the Gantt chart very well, it still retains the basic features of the standard Excel chart:

  • The project schedule Gantt chart in Excel will resize when tasks are added or removed.
  • You can change the Start date or Duration, the chart will reflect the changes and adjust automatically.
  • You can customize your Gantt style chart in Excel in a variety of ways by changing the fill color, border color, shadow. All of these options are available in the Data Format tab.
  • Once you've created your design, it's a good idea to save the Gantt chart planning in Excel as a template for future use. To do this, right-click in the chart area, and select "Save as Template" from the context menu.

Further, we will tell you how to create a Gantt chart in Excel. 

How do I create a Gantt chart in Excel?

To make the project planning Gantt chart you need in Excel, you need to sequentially do the following:

  1. Create a table with a list of tasks. Before you build a Gantt schedule in Excel, you need to prepare an information array for its formation. All current tasks are sorted here by start time - the earlier the execution of a particular task starts, the higher the line occupied by it is located. Also, for each stage in the Gantt timeline, you need to specify the end date and duration in days. The most important thing here is to enter the maximum number of all tasks because in the future it can be difficult to do this - often you have to change the entire schedule format.
  2. Building a diagram. To create a Gantt chart in Excel, select the following menu items in sequence: "Insert" - "Bar chart" - "Stacked Bar chart". After that, you need to bind its columns to the data entered earlier. To do this, use the "Select Data ..." command. You need to specify the correct data ​​for the "Series Name" cells and the correct range for the data field. When all the data is specified, you need to configure the display of tasks instead of their start dates on the left side of the graph. To do this, click on any of its lines, right-click on the "Select data ..." item, find the "Horizontal line labels" block - and click on the "Change" button. Now we can set the required range of cells from which the chart will take names for tasks - we registered them at the first stage.
  3. Chart formatting. Here we need to configure the display of information in the graph. Foremost, we set the correct sequence of tasks - we click on their list, right-click to call the "Format Axis" menu - and check the box "Reverse Order". You can remove the description for columns with start and finish dates and duration. Also, for clarity, you can hide the beginning of lines illustrating tasks. By default, they go from the vertical axis regardless of the start date. You can do this by removing the fill and border lines. It also makes sense to remove extra spaces and remove the void left at the beginning of the diagram.
