With the introduction of computers in the project management, project managers learned how software helps create and update their Gantt charts. 

It saves time and improves the efficiency of the projects through this digital Gantt chart software. 

These Gantt chart software are basically project management software that helps in planning, automating, and scheduling tasks. 

It automates the processes to boost the efficiency of the projects, where it supports advanced Gantt requirements such as adding milestones, task dependencies, and much more. 

However, many project managers use traditional desktop programs such as Microsoft Projects. 

😳What is the history of a Gantt Chart?

The “Gantt” name comes from the last name of the creator of Gantt Charts named, Henry Gantt. He was an American mechanical engineer and management consultant. 

He designed the diagram by publishing further about their inventions in 1910 and 1915. 

Karol Adamiecki, a Polish Economist, management researcher, and engineer, was surprisingly introduced to the diagram even earlier in 1986.

He published his first work in 1909, and later in 1931, he managed to publish more recognized work. 

His more popular articles where he described the diagram to be named her monogram, which was the chart like Gantt charts. 

The Gantt chart was named after Henry Gantt, and not Karol Adameicki was quite obvious. 

Henry was American and wrote in English, whereas Karol published his articles in Russian and Polish. 

Here is the chronological order of how the Gantt chart was discovered : 

  • 1986: Karol Adamiecki designed a harmonogram at its initial stage for it to be Gantt Chart.
  • 1903: Henry Gantt discovers the charts to increase the visibility of the production schedules.
  • 1903:  The inventions from Adameicki made a stir in the technical and social circles in Russia.
  • 1909:  Adameicki publishes his articles in Polish describing the diagram.
  • 1910-1915:  Henry Gantt further develops the diagram, publishes his article, and makes it more popular.
  • 1931: Adameicki publishes more of his articles about harmonogram in Russia and Polish.
  •  Now: Gantt Chart is one of the most successful and popular tools in project management. 

🤨Why Do You Need a Gantt Chart? 

According to the Gantt chart creator, it was created to help display the project schedule.  

In other words, it helps you demonstrate the best way to deliver the project over different metrics, primarily time. 

It allows you to see how you can complete the project in the fastest way possible and most effectively. 

Gantt chart is an effective mechanism to record the progress of your project through monitoring and time-capsuling different milestones or tasks. 

Simply put, it helps you break down your project, irrespective of its size or scale, into small achievable tasks set with a deadline. 

When more people are involved in project completion, you can record how every team member works on the project. 

It allows you to customize, organize, control, and manage the quantity of the work done on the project over different or particular team workers at a given time. 

You won’t have any issues with tracking multiple activities undergoing your project. 

Also, tracking the progress of your project on the basis of different deadlines, tasks, and team members is easier with Gantt charts. 

🎁Benefits Of Online Gantt Chart Software

It Allows Remote Enhanced Communications 

Today, when most projects are done remotely in all domains of the work, project management also needs to be managed remotely. 

Gantt charts software is what works tremendously effectively in terms of team communication for a particular project. 

Project managers can see any particular part of their project and check the status of it and all the recent development. 

They can also monitor the project in real-time and see who is working on what. Moreover, they assign a dedicated person to work on a certain part of the project or allotted task to fulfill. 

It is so easy to communicate, coordinate and get feedback from the team members through Gantt charts. 

It works perfectly for high-level projects which involve different hierarchies of team members ranging from stakeholders to remote workers. 

The system is also capable of accommodating different teams, and their team leaders sync to work on projects on different aspects in real time. 

It Has a Higher Ability To Track Progress 

Gantt charts make sure that you stick to your deadlines, not just for your overall project but the tasks within as well. 

You will be able to track your progress and see how you proceed through different milestones of your project. 

The Gantt chart also allows you to complete different tasks and subtasks of your project on given deadlines. 

There are micro-management options and tons of tools to help you to monitor your progress on every step. 

It Also Helps You Avoid Resource Overload 

One of the major advantages of the Gantt chart is that it helps you prevent resource overload.  

It allows you to tackle numerous team problems whenever your resources are stretched too thin across various tasks. 

This tool helps you manage your resources effectively, ensuring no single team member is overburdened. 

Conversely, it also shows that no team member will lack the resources to do the project. 

🖥️Desktop vs. Online Gantt Chart Software

Project management software or programs are extremely developed today, which the teams work on. 

What makes Gantt Chart software best suit the manager who prefers to plan the project individually without sharing the plan with others?

Then, the manager further shares the project with different and dedicated individuals from the team. 

Desktop Gantt chart software allows one local version per user license, just like any other project run on Word or Excel. 

Sharing the large Gantt chart without any enterprise integration of sharing hubs such as Sharepoint can be really difficult. 

Even with using Sharepoint, the people to whom you are sharing the file will need a desktop license of the planning software to access it. This can further increase the cost for sure.

Gantt chart software is easy to share and is highly collaborative in project planning for all kinds of projects. 

Since the project is online, anyone you particularly invite can only be able to see the project plan. They are also able to update the tasks and attach files as well. 

The cost related to the project management is dramatically less than what it would take up on the desktop version. 

It is because you don’t have to pay anything for server installations, license costing or any integration costs for every user. 

🌌Elements Of Gantt Chart 

components of gantt charts

Every Gantt chart project has specific elements or components required to make it happen. 

These elements of the Gantt chart can be seen in any Gantt chart software. You will surely find more elements constituting the efficiency of the Gantt chart, but five of them are extremely crucial. 

The most important five elements of the Gantt Chart are :

  1. Tasklist
  2. Task Duration Bars
  3. Task Owner Indicator 
  4. Task Dependency Arrows
  5. Date Indicator 

Task List

You will spot the Tasklist, usually on the left side of the Gantt chart. It corresponds with their particular task duration bar located at the center of the screen. 

So these are your targets, tasks, or deliverables you are working towards to accomplish them.  

You can further break down this list dedicated to different teams or team members or task-type groups as well. 

Task Duration Bars

It is certainly amongst the most crucial parts of the Gantt chart. It represents how long a particular task is scheduled for completion. 

Or in other words, it is given time to complete the particular task. Gantt chart software allows you to change the duration by clicking and dragging the bars. 

Task Owner Indicator 

Image Source: FusionCharts

Every task in the Gantt chart will represent who is the responsible person for completing it. 

By clicking on the task, it needs to show the task owner indicator reflecting the responsible person from the team. 

Task Dependency Arrows 

Image Source: SmartSheet

You won’t find the Task dependency arrows or lines for all the project management software; it is also not always required. 

However, when required, they are represented with an arrow or a connecting line showing that a task needs to be completed before another begins. 

Date Indicator

You will be still see the calendar dates running along the top of the chart; there will be what you should call a date indicator. 

It will be represented with vertically highlighted segments of the chart or a vertical line. 

✨Dependencies And Task Relationships

Finish-to-Start (FS) relationships

A Finish-to-Start relationship is the most common type of task dependency in Gantt Charts. It signifies that one task must be completed before the next task can begin.

The start of the successor task depends on the predecessor task’s completion. For example, the coding phase (successor task) cannot start in a software development project until the requirements gathering phase (predecessor task) is finished.

Start-to-Start (SS) relationships

A Start-to-Start relationship indicates that two tasks must start simultaneously or have a specific time lag between their start dates. In this type of relationship, the start of the successor task is dependent on the start of the predecessor task.

For instance, in a construction project, the excavation and foundation pouring tasks may have a Start-to-Start relationship, where they must begin simultaneously.

Finish-to-Finish (FF) relationships

A Finish-to-Finish relationship implies that two tasks must finish simultaneously or have a specific time lag between their finish dates. The completion of the successor task is dependent on the completion of the predecessor task.

An example of this relationship could be two parallel testing activities in a quality assurance project, where both must finish simultaneously or have a predefined gap between their completion dates.

Start-to-Finish (SF) relationships

A Start-to-Finish relationship indicates that the start of the successor task is dependent on the completion of the predecessor task. In other words, the successor task cannot start until the predecessor task is finished.

This type of relationship is relatively less common in Gantt Charts but can be useful in specific scenarios. For instance, in a training program, the issuance of completion certificates (successor task) may start only when all participants have finished the training (predecessor task).

☄️How To Create A Gantt Chart?

Gantt chart is an essential feature in any project management software or tool. It is very easy to create Gantt charts online. 

You can create new task lists or import one, and you can see how it impacts your Gantt bars for easy visual understanding. 

It gives you a detailed and precise visual representation of your projects, including the tasks, roles, and so much more. 

Here are the usual steps you need to follow in order to create a Gantt chart that you can find in project management software. 

Step 1:  Create A New Project 

Login to your project management software and create a new project to begin with your Gantt chart representation of your project. 

You will find the option “Create” in the project management software or tools. You also have to name your project as well. 

Step 2:  Add Tasks 

After login into the project management software, you can start adding tasks. 

The default date will be today because you haven’t added any longer due date further than today. 

When you add the task, it will visually show up in the Gantt chart. It shows the visual representation of where it starts and where it ends.  

You can see the current date in the dotted lines. 

Step 3:  Add Due Dates 

You can always change your deadlines with an effect seen on the Gantt bars. It represents how long every task will take. 

📈Interpreting and Analyzing Gantt Charts

Tracking progress and project timeline

Gantt Charts provide a visual representation of tasks and their scheduled durations. By regularly updating the Gantt Chart with the actual progress of tasks, you can track the project’s progress and compare it against the planned timeline.

For example, if a task was supposed to be completed by a certain date but is falling behind schedule according to the Gantt Chart, it indicates a delay in the project timeline.

Identifying critical path and project bottlenecks

The critical path in a Gantt Chart represents the sequence of tasks that determines the overall project duration. By analyzing the dependencies and durations of tasks, you can identify the critical path and the tasks that have the most impact on the project’s timeline.

Bottlenecks are areas where tasks or resources are causing delays or hindering the smooth flow of the project. Identifying critical paths and bottlenecks helps you focus on addressing the most crucial tasks and resolving any issues that may be impacting the project’s progress.

Resource allocation and workload management

Gantt Charts not only show task durations but also allow you to assign resources to each task. By visually representing resource allocation, you can see if resources are evenly distributed or if there are any resource conflicts.

This helps in effective workload management and ensures that resources are not overburdened or underutilized.

For example, suppose multiple tasks are assigned to a single resource simultaneously. In that case, it may indicate an overload, which can be adjusted in the Gantt Chart by redistributing tasks or adjusting timelines.

Visualizing project dependencies and relationships

Gantt Charts excel at visualizing task dependencies and relationships. By examining the interconnections between tasks, you can understand how changes in one task can impact others.

This visualization helps in identifying the order in which tasks should be executed and highlights any dependencies that may be affecting the project’s progress.

For instance, if a predecessor task is delayed, it will be clearly visible on the Gantt Chart and enable you to address the necessary adjustments accordingly.

Communicating project status and updates

Gantt Charts serve as a powerful communication tool for sharing project status and updates with stakeholders. By presenting a visual representation of tasks, timelines, progress, and dependencies, you can easily convey the project’s current status, milestones achieved, and any changes that have occurred.

Gantt Charts facilitate effective communication by providing a clear and concise overview of the project’s progress, ensuring that all stakeholders are informed and aligned on the project’s status.

✍️Advanced Gantt Chart Techniques

Adding Dependencies And Constraints

Advanced Gantt Chart techniques involve adding more intricate task dependencies and constraints. This helps in accurately representing the relationships between tasks and ensuring that they align with specific requirements or limitations.

Using Baselines For Performance Measurement

Baselines in Gantt Charts are snapshots of the initial project plan. Creating baselines allows you to compare the planned schedule with the actual progress. This technique allows for effective performance measurement and helps identify any deviations from the original plan.

Implementing Resource Leveling

Resource leveling is a technique used to balance resource allocation and workload within a project. You can avoid resource overloading or underutilization by leveling resources in a Gantt Chart, leading to more efficient resource management.

Incorporating Buffers And Slack Time

Buffers and slack time are additional blocks of time added to tasks to account for uncertainties, delays, or unexpected events. By incorporating buffers and slack time in the Gantt Chart, you create flexibility in the schedule and allow for better management of project uncertainties.

Handling Project Changes And Delays

Advanced Gantt Chart techniques include strategies for handling project changes and delays effectively. This involves updating the Gantt Chart promptly, assessing the impact of changes on the schedule, and adjusting task dependencies and timelines accordingly.

💳Best Practices For Gantt Chart Usage

Keeping The Gantt Chart Updated

One of the best practices for Gantt Chart usage is to regularly update the chart with the most current information regarding task progress, changes, and milestones achieved. This ensures that the Gantt Chart accurately reflects the project’s status.

Regular communication and collaboration

Effective communication and collaboration among team members are crucial for Gantt Chart usage. Regularly discussing and sharing updates, milestones, and dependencies helps in maintaining alignment and enables timely decision-making.

Using color-coding and formatting effectively

Utilizing color-coding and formatting in the Gantt Chart enhances readability and comprehension. Assigning colors to different task categories, milestones, or priorities helps quickly identify important information and improve visual clarity.

Using Gantt Charts for different project types

Gantt Charts can be used across various project types, from small personal projects to large-scale enterprise initiatives. Understanding how to adapt the Gantt Chart for different project requirements ensures its effective utilization.

Training and educating team members

Training and education to team members on using and interpreting Gantt Charts increase their effectiveness. This empowers team members to engage with the Gantt Chart actively, contribute to its maintenance, and make informed decisions based on its insights.

↗️Gantt Charts And Project Management Methodologies

Gantt Charts in Waterfall project management

In Waterfall project management, Gantt Charts are often used to plan and visualize the sequential execution of tasks.

The linear nature of Waterfall projects aligns well with the timeline representation in Gantt Charts.

Gantt Charts in Agile project management

Agile project management focuses on iterative and flexible approaches.

While Gantt Charts may not be the primary tool in Agile, they can still be used to provide high-level overviews, track major milestones, or showcase dependencies in Agile projects.

Gantt Charts in Hybrid project management

Hybrid project management combines elements of both Waterfall and Agile methodologies.

Gantt Charts in hybrid project management can bridge the two approaches, offering a comprehensive view of project timelines and dependencies while accommodating iterative and adaptive practices.

💎Gantt Chart Applications

Identifying the Sequence of the Events 

One of the primary uses of Gantt chart applications or use cases is finding a critical path. 

It helps in identifying the longest sequences of the events that go under a project. Gantt chart allows you to streamline the process on the metrics of time and tasks. 

It visualizes the connection between the components, such as time, tasks, and order in your project. 

So it is an ideal way to visualize a critical path through your project and see how time links the tasks in order to make it happen. 

Visualizing Various Project Scenarios 

If you have a project to complete and feel stuck on how to proceed with it, Gantt charts can help you visualize the different project scenarios to go for. 

It tells you hundreds of ways to plan your project with different sets of tasks, time, and management to fulfill. 

Using the Gantt chart, you can go over various permutations and combinations of scenarios for your project to see what is the best option for you. 

You can see particular tasks or activities lining up in the sequence in order to complete the project. 

Eventually, with brainstorming, you will be able to find out the best route to complete your project in the best, fastest, and cheapest way possible. 

Predicting The Estimated Time

Gantt charts are extremely helpful in predicting the delivery dates or estimated time for the fulfillment of the project. 

It allows you to specify the duration of every particular task set on a timeline, making you right on time for your delivery point. 

It helps you predict the estimated delivery date and time while fulfilling all the deadlines for the specific tasks in the project as well. 

Not just that, it further helps in the management of the planning of the cost and finding out the profitability. 

So overall, you can predict the estimated duration of the project or streamline the whole project in terms of time stamps and deadlines for each task. 

Delegating Tasks 

Gantt chart formation always means to be breaking down your project into bite-sized activities or tasks to fulfill.  

This helps you to delegate tasks to different dedicated team members who are good at particular tasks or skills.  

Also, it allows people to see how they can all contribute to this huge project in their own way. 

It boosts the culture of responsibility and accountability, making your team stronger to work together. 

By delegating the task, also improves the quality of the project as you will optimize every particular task by assigning them to a dedicated team member with the relevant skill set to complete it. 

Demonstrating The Progress 

Gantt chart is a highly dynamic and well-documented report that is connected to your workflow, deadline, and streamlined procedures. 

It is easy to demonstrate the progress of your project whenever you want to show it in a status update meeting. 

Demonstrating the timeline of the project with detailed addressed updates is what you can easily highlight in your Gantt chart. 

This is most certainly the best way to represent your project to your stakeholders or update them on the project over time. 

❗Common Mistakes to Avoid with Gantt Charts
