Introduction:- 

In the field of project management or any other major industry segment, a popular term we often come across is task management, data management, or project scheduling. We all know how every project spans across months and comprises multiple tasks and subtasks. This is where a Gantt chart comes into play. A Gantt chart is a data chart that most professionals and industry experts refer to when they discuss project visualization before planning its lifecycle.

What Is a Gantt Chart?

• Definition

An effective  project management tool that provides a visual representation of the tasks to be done within a specified timeline. This resembles a bar chart, outlining the timeline of a project, particularly an iterative one. These task management tools represent a list of tasks and their timelines, along with task dependencies, through horizontal bars.

• Who invented it?

The Gantt chart was invented in 1910 by Henry Gantt, an American mechanical engineer. Although a Polish engineer, Karol Adamiecki, had previously developed the concept of listing tasks against a timeline, it was Gantt who popularized the idea and even published articles on this subject, which made it popular in Western countries.

Core components (tasks, dependencies, milestones, timeline)

The core components of a Gantt chart —tasks, dependencies, milestones, and timeline —cooperate to create visual project models. In the Gantt sheet, the vertically listed activities define “tasks”. Dependencies are shown by the lines connecting two tasks, milestones represent significant achievements in a project, and the horizontal axis, highlighting the dates, represents the timeline.

Why Use a Gantt Chart in Project Management?

• Purpose

The purpose of the Gantt Chart, as a popular project management tool, is to facilitate planning, scheduling, and tracking of projects of every size over a timeline. Being extremely visual, a Gantt chart is an ideal option to monitor the progress of any project at all times.

• Benefits

There are multiple benefits of Gantt charts that users can utilize for both work and personal use. For instance, it is a great tool for mapping and coordinating tasks, identifying overlapping activities, efficiently allocating resources, representing task dependencies, milestones, and tracking project deadlines.

How to Create a Gantt Chart? (Step by Step)

• Define tasks - The foremost thing is to understand the required deliverables (tasks) for the project. Break down the complex tasks into a list of priority tasks.
   
• Set dependencies - For all dependent tasks or those closely related, establish task dependencies so that the team is clear about the first set of tasks to be accomplished before the next set of functions.
   
• Add timelines - Create a timeline that includes the entire set of tasks to be completed within that specified period. Determine the estimated time that each listed task might take and add a start and end date to it.
   
• Assign resources - Take time to curate the chart, format it, and assign resources. Create a list of team members who will lead the task and ensure it is closed. This will be a significant detail to include in the Gantt chart.
   
• Track progress - The main purpose of the Gantt chart is to measure progress. Therefore, ensure to integrate bars with percentages to identify the status of each task listed and regularly update them. 

Who Uses Gantt Charts?

• Project managers- Project managers can use Gantt charts to get a clear overview of the  project schedule and timelines, which we precisely refer to as the project lifecycle. With this chart, one can be informed of the start and end dates of a project, as well as the estimated duration it will take. Furthermore, this chart can assist managers with other specifications, including the project members involved in the work, the progress made to date, defining the project scope, the task schedules, and the resources utilized, among others.

  Other industries where Gantt charts are highly used include:

• Construction - Helps with scheduling, managing, and tracking resources for a project over time.
   
• Information and Technology - Ideate, plan, schedule, and manage complex projects by simplifying them into small tasks. See task dependencies and record progress.
   
• Event Planning - Create a smart event timeline to oversee and manage tasks, fostering effective communication within the team and with the stakeholders.
   
• Marketing - In the field of marketing, Gantt charts can help you plan, schedule, and track campaign performance and product launches, as well as facilitate collaboration.

When Should You Use a Gantt Chart?

• Best scenarios

There is more than one ideal scenario where you can use Gantt charts. For example, when managing complex projects with numerous task heads, tasks that have clear dependencies or those that need to be completed within a specified timeline are often encountered. Additionally, Gantt charts can be used for collaboration, task planning, milestone tracking, resource allocation, project scheduling, and many other purposes.

• When not to use?

When working on highly iterative Agile projects (which are open to new changes and discoveries), highly detailed assignments, or dynamic projects, Gantt charts are not a reliable option. Also, if you have simple and quick tasks to accomplish, maintaining a Kanban board may be sufficient.

Do not use it when you are the one in charge of your project, or when you want help regarding resource management. Additionally, if you are aware of other efficient software and tools to manage tasks and timelines, you can skip using Gantt charts.

How Are Gantt Charts Used in Project Management?

• Product launch

Gantt charts are a powerful tool for efficiently managing product launches. More than just providing a visual overview of progress, it helps with the planning, tracking, and organization of all tasks listed on a particular project delivery or product launch. There is an option of a timeline structure, followed by other features, including task dependencies, task delegation, and progress monitoring in a Gantt chart, which enables one to manage even the most complex assignments.

• Event planning

Most of us know how having a clearly designed Gantt chart can help represent even the most complex data to the users. Not only that, a well-structured Gantt chart is known to provide a bird’s-eye view of a subject matter, project, or problem, allowing one to easily visit and revisit the events and actions within that specific project. Additionally, a Gantt chart provides a visual representation of every detail and piece of information in one place, with starting and end dates properly mentioned.

• Software development

Gantt charts play a pivotal role in software development and design. It can be used to analyse data and break down complex tasks into small, manageable tasks. Every task is presented alongside a realistic timeline so you know the final date of closure and can track the work progress every day until its completion. Gantt charts particularly help with planning, development, testing, and deployment, as well as managing other project or software creation requirements

FAQs:

1. How to color-code Gantt charts?

   Color coding in Gantt charts is a great way to simplify a complex depiction. Gantt charts are mostly used to showcase data (project status) through various stages. For instance, boxes marked in red would define pending tasks, yellow defines tasks that need some work (attention), and green refers to the completed tasks. There could be more colors as well, which can be used to represent various other statuses of a project.

2. Are Gantt charts used in predictive projects?

   Yes, they are popularly used in predictive projects because of the countless interesting features and specifications they offer for clarity. When you use Gantt charts for predictive projects, you can quite effortlessly create a visual timeline of tasks, show project timelines, schedules, and task dependencies, and help manage resources efficiently. These are a form of Gantt chart that precisely highlight a lot of details, including the dates and times taken to complete a project, identify the sequence of tasks, and facilitate collaboration on ideas for the ongoing project with stakeholders.

3. What does a Gantt chart show?

   Gantt charts are a type of bar chart that highlight a graphical depiction of a project schedule. Present-day Gantt charts incorporate multiple other new features, showing the dependency relationships between activities and the status of the project.

   The idea behind using Gantt charts is to prioritize the timely commencement of tasks with proper and planned scheduling once all the remaining factors are in place. Following this process often utilizes the float time (which is the duration till when the tasks within a project can be pushed without delaying the delivery date of the project, or the list of succeeding tasks.

4. How does a burndown chart differ from a Gantt chart?

   A burndown chart is beneficial for large projects that have multiple dependencies. Here, the time and ratio of tasks completed within that timeframe are constantly taken into account, in addition to the user who accomplished them.

   Whereas a Gantt chart is a popularly used chart in the  project management segment. This chart simply depicts project schedules, activities, and starting and closing dates of a project’s elements, like resources, milestones, planning, and dependencies, in bar formats. One can consider this chart as a visual timeline and then eventually structure a plan that works for them in accomplishing those tasks.

5. What are the two types of Gantt charts?

   The two types of Gantt Charts include Local Gantt Charts and Global Gantt Charts. The local Gantt chart highlights a detailed overview of a particular project’s tasks and subtasks, whereas a global Gantt chart offers a distinguished idea of multiple ongoing projects, which further helps in comparing the scheduled versus actual dates for project completion.

   There are four types of Gantt chart task dependencies, namely - Finish to Start (FS), Start to Start (SS), Finish to Finish (FF), and Start to Finish (SF).

6. What is the Gantt chart format?

   There is no fixed format for Gantt chart creation. One can design it as per their project requirements and convenience. Essentially, every Gantt chart includes certain crucial details such as timelines (task durations), task lists, resource allocation information, milestones, and dependencies. To start with, one can use an online Gantt chart template (there are several available online!) that best suits their needs. With these easy-to-tailor Gantt charts you can find countless features like task categories, priority levels, progress status, and even establish open communication channels.
