Gantt Chart vs. WBS: Choosing From Two Reliable Ways to Plan Your Project

Gantt chart versus WBS: what to choose

Audio version:

The world of project management contains many powerful tools, including various graphical diagrams and visual hierarchical structures. 

“Gantt chart vs. WBS” is an important topic that should not be ignored, as it is critical to distinguish these tools, understand their purposes and scope of use.

Although these terms are sometimes used interchangeably, they are not synonyms and usually relate to different management tools.

It may seem that all the structures similar to a Gantt diagram have already been identified and investigated, as we’ve recently analyzed such important pairs as:

However, WBS (Work Breakdown Structure) is also worth adding to this list.

Let’s delve into details to figure it out. 


What is a Gantt chart?

A Gantt chart is a bar chart that showcases a project’s progress, timeline, and dependencies – all in a highly visual and easily understandable view. This is one of the most widely used management tools for project scheduling and control.

The diagram was developed more than a hundred years ago by the American Henry Gantt. 

It allows scheduling projects and their corresponding tasks while getting an overview of the entire project process.

Here are the core elements of a typical Gantt chart:

  • A timeline – the backbone of the chart. It is more than a regular timeline where you can see how your project activities are progressing. A Gantt diagram allows users to zoom in and out of their timelines and add more valuable elements.
  • A bar – a visual representation of a project or a task. It demonstrates the length of time and allows seeing who is engaged in that task.
  • Resources – what makes your projects tick (people, equipment, and machines that bring projects to fruition). 
  • Dependencies – showcase how your tasks are linked together. 
  • Milestones – measure the project progress and show how it approaches the goals that have been set.

Besides, the diagram allows you to see time estimation for each activity, team members’ comments, activity overlaps, deadlines, and more.

Some people admit that a Gantt chart looks like a row of dominos. What do you think about it? 🙂

Gantt chart examples

A bar diagram is commonly used to display a work plan, track the progress, and monitor task implementation. Looking for the real-life Gantt chart examples, you can find vivid cases from project management, construction, software development, marketing, event planning, business planning, and other spheres and sectors.

Here’s an example of how you can apply the diagram for creating a SEO marketing plan.

After the detailed analysis of the famous histogram, it’s time to find out more details about its opponent in the “Gantt сhart vs WBS” pair.

What is a Work Breakdown Structure?

A WBS is a detailed tree structure of different tasks and deliverables that need to be done to complete a project. 

Businesses that don’t value project management experience 70% more project failures. Therefore, good work organization looks like a “lifesaver” to many, and the WBS can really help.

What is a Work Breakdown Structure in project management?

This structure is the foundation of project planning alongside a Gantt diagram. These two approaches are probably the most common project management tools. 

Project managers apply WBS to divide large projects to get things done faster and more efficiently. 

Breaking them down into smaller chunks means work can be performed simultaneously by different team members. It leads to better team productivity and successful project management.

WBS Work Breakdown Structure in project management

Why is WBS importnat in project management?

The preparation of WBS has the following practical advantages:

  • Provides clarity about the tasks to be performed. It reduces complexity by dividing the entire project into smaller phases.
  • Increases efficiency. WBS ensures that all necessary measures are taken and that a realistic time schedule can be carried out.
  • Provides each project participant with an overview of the current status, from which they can deduce at what point their tasks are inserted.
  • Enhances communication. The complete representation of the WBS can support communication as it boosts transparency and promotes effective discussions.
  • Creates the basis for further planning. WBS is also the prerequisite for determining whether more detailed plans are needed. It reduces the risk of unplanned and unexpected costs.

Work Breakdown Structure examples

Your WBS can be different for each project. Sometimes it requires time to experiment and see which Work Breakdown Structure works best for your team. 

The main idea is to show the hierarchy of your projects and make progress clear to everyone involved.

A Gantt chart can be considered one of the famous WBS examples. You can organize your Work Breakdown Structure as a Gantt diagram that links task dependencies and reflects project milestones.

Here are some more WBS examples:

  • WBS spreadsheet (where you can also note different phases, tasks, or deliverables in columns and rows).
  • WBS flowchart.
  • WBS list.

Using any Work Breakdown Structure example, you can organize and manage your events. For example, seasonal team-building activities or your holiday trip. Here’s how it may look like:

WBS Work Breakdown structure for event planning

What is the difference between a WBS and a project plan?

A project plan and WBS are different management tools, and they usually don’t refer to the same concept. (Hopefully, you remember how to create a project plan with all the necessary details and nuances).

  • WBS is at the core of project planning. Managers use it to divide the project into controllable elements. It gives them a hierarchical representation of all work required to complete their projects. 
  • A project plan establishes a general framework that guides all further planning. This document defines how the project will be managed and controlled.

Work Breakdown Structure tools

Creating WBS is a reliable way to get a project off the ground and ensure its efficient execution.

There are many Work Breakdown Structure software solutions out there. When you choose one, you get a simple way of outlining the project scope and project deliverables.

We have analyzed both tools and now it’d be helpful to briefly highlight the main points of their differences.

Gantt chart vs. WBS

Project management professionals typically apply a WBS to show what they are doing and use a Gantt chart to visualize when they are doing it.

Let’s take a look at some more critical differences between the two structures.

Gantt chart vs. WBS: how do they differ?

When to use a Gantt chart

Handling project management with a Gantt chart ensures numerous benefits, including detailed scheduling, accurate task planning, improved efficiency, and increased accountability. 

Here are some essential points to help you choose the diagram:

  • It displays a detailed schedule of tasks related to a project across two axes.
  • It visualizes the project tasks with their dependencies, critical project milestones, and other essential details. It shows the start and finish date of each task and their relationship to each other.
  • It can be helpful throughout the whole project.
  • It is commonly used for schedule control.
  • You can build it using a bar-chart system with the help of different tools (from simple Excel to complex project management software solutions).

When to use a Work Breakdown Structure

A Work Breakdown Structure will assist you in any case when you need to break your project down into a hierarchy of deliverables and tasks.

Keep in mind the following characteristics of this method:

  • It is an organization chart or a tree diagram, with all parts connected and no redundancy.
  • It does not show the tasks organized in sequence over time. Managers use it to define the scope, estimate costs, allocate resources, manage risk, and create schedules.
  • It looks super helpful at the start of a project (in comparison with the invention of Henry Gantt that can assist throughout the whole project).
  • It is used for scope control, including change management.
  • You can visualize it with a Gantt chart,  flowchart, spreadsheet, or a list, using various tools and approaches.

Final words

A Work Breakdown Structure and a Gantt diagram are the essential tools in project management. That’s why the battle “Gantt chart vs. WBS” looks actual and raises many questions.

The WBS can be considered the skeleton of your future project plan. It drives decisions concerning establishment of the project scope, task identification, and resource allocation. Therefore, modern PM tools contain the option to build a Gantt chart within the Work Breakdown Structure functionality. 

Both concepts allow teams to be informed of the progress made. They boost team efficiency and lead individuals to successful decisions.

The only thing that remains is just to remind you that the topic “WBS vs. Gantt chart” will not be fully perceived without the practical use of robust PM software.
