Project management is a complicated process that requires a significant amount of time.

Keeping track of timelines, dependencies, and resources is crucial to ensuring the timely completion of a project within budget. This is where Gantt charts come into play.

If you’re a project manager in Nigeria, you have probably heard of a Gantt chart. But what exactly is it, and why is it so important?

In this article, we’ll discuss what Gantt charts are, how to use them, and the benefits of using them.

What are Gantt Charts?

A widely-used instrument in project management, the Gantt chart enables project managers to have a clear picture of the project schedule, oversee advancements, and ensure that team members are well-coordinated and oriented. 

The idea behind a Gantt chart is to visualise the project timeline and development.

 It allows you to see each task’s start and end dates and their dependencies on each other.

The chart helps you understand the project’s progress and identify potential roadblocks or delays.

Interestingly enough, the initial application of Gantt charts was in managing construction projects. But they’ve since been adapted for other industries and projects.

Anatomy of a Gantt Chart

A Gantt chart has a horizontal bar chart and a timeline. The horizontal bars represent project tasks or activities, and their length shows the expected duration of each task.

The timeline typically shows dates, weeks, or months, depending on the project’s timeline.

Tasks are divided into sub-tasks, and represented by shorter horizontal bars under their parent task.

These allow the breakdown of long tasks into smaller, more manageable parts.

Gantt charts can be customised with colours, labels, and other visual aids to improve understanding.

For example, you may use different colours to indicate tasks that are in progress versus tasks that are complete.

Getting Started With Gantt Charts

Working with Gantt charts can be overwhelming, especially if you’re not familiar with the software and tools available.

Here’s an overview of a few Gantt chart tools to help you get started.

  1. Microsoft Excel

Microsoft Excel is a well-known spreadsheet program that can be used to create Gantt charts. Excel offers a variety of built-in templates for Gantt charts that you can customize to fit your project needs.

How to Create a Gantt Chart  For Your Project

Creating a Gantt chart for your project can seem daunting, but it is not necessarily so. Follow these simple steps to create a sample Gantt chart that fits your project needs.

  1. Identify your tasks

To begin creating a Gantt chart, it is crucial to first determine the tasks that require completion.

Let’s consider an instance where we are organizing a marketing campaign for the launch of a product. Our tasks could include:

  • Develop campaign
  • Design materials
  • Create content
  • Execute campaign
  1. Determine the duration of each task

After identifying the tasks, the next step is to determine their duration. This involves figuring out the length of time required to complete each task.

In our example, we’ll assume that the tasks have the following durations:

  • Develop campaign: 3 weeks
  • Design materials: 4 weeks
  • Create content: 4 weeks
  • Execute campaign: 1 week
  1. Create your gantt chart

With the identification of tasks and their respective durations, it is now possible to create the Gantt chart.

While there are various tools available, we will use Microsoft Excel for this particular example.

  • Open a new spreadsheet in Excel.
  • Create a table with four columns: Task, Start Date, Duration, and End Date.
  • Enter your tasks in the first column.
  • In the “Start Date” column, input the specific date that marks the beginning of each task. For our example, we’ll assume that the campaign launch date is April 1, 2023.
  • In the “Duration” column, input the number of days that will be required to finish each task. 
  • In the “End Date” column, a formula should be applied to compute the final date for each task. For example, if the start date for a task is March 26th, 2023, and the duration is 5 days, the end date would be March 30th, 2023.
  1. Format your gantt chart

Now that you have created your Gantt chart, you can format it to make it easier to read and understand. Here are some suggestions to enhance the Gantt chart:

  • Incorporate colors into the bars to make them more visually appealing.
  • Use grid-lines to separate the tasks.
  • Adjust the font size to make the chart easier to read.

Here’s what your Gantt chart could look like:

  1. Frequently adjust Gantt chart to depict alterations or progress made 

As the project progresses, ensure the regular update of the Gantt chart with any changes such as subtasks, individuals assigned to each task, or progress made. 

It will help you stay on track and ensure everyone on the team knows the project’s current status.

Here’s what a Gantt chart with subtasks, individuals assigned, as well as progress report looks like:

Keep in mind that the dates provided are merely samples and can differ depending on the specific project’s requirements and timeline. 

When creating a Gantt chart, it is important to take into account the time required for each task and the ones that are reliant on the completion of others before they can commence. 

Ensure to allocate adequate time between tasks to account for any unpredicted setbacks or alterations.

Additionally, ensure to remove days when your team does not work, such as weekends, to have a more accurate representation of the project schedule.
