The Difference Between Gantt Chart And Work Breakdown Structure?

What is the difference between the Gantt Chart and WBS?

In Project management understanding the difference between the Gantt chart and work breakdown structure is very important.

Difference Between WBS And Gantt Chart

Instead of reading the article, You can check out the video which has explained everything about WBS and Gantt chart with details as well as we shared some examples.


  1. The WBS is a hierarchical listing of all the project activities involve small and major. Each work activates should include an appraised budget and effort (that is timespan to complete the task if one person on it is working on it continuously).
  2. The work breakdown structure (WBS) is a hierarchical list that demonstrates the major activities and elements of a project. Typically the WBS consists of an organized task list with an estimate of the time and resources required and the responsible person.
  3. WBS shows you the breakdown and sub-activities of the large and small project scope and deliverables.
  4. WBS focuses on “What”. Mean what are the major and sub-activities.
  5. WBS is defined as the process in which the entire Project ( project, portfolio, Large project) is divided into different packages & each of these packages is further divided into sub-packages or activities depending upon the level of the schedule being prepared.
  6. Show the activities and sub-activities of the task of the project and to whom these tasks are assigned. Or how much cost of each task cost or have with a specific budget assigned by the project manager.
  7. Every major project be made up of many tasks, events and to every person tasks assigned are different, and also the budget of each task and events are different here the WBS is the best tool to show this scenario.
  8. WBS nor demonstrate the schedule and time span of the project but are tools to make a hierarchy of the large and small projects.
  9. WBS refers to the process of breaking big tasks (in the case of the big project the one task can also be breakdown through WBS) into smaller ones and breaking the resulting tasks into even smaller tasks.
  10. WBS is a critical project deliverable that classifies the team’s work into manageable sections. The Project Management Body of Knowledge (PMBOK) defines the work breakdown structure as “A hierarchical decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create the required deliverables.
  11. A WBS shows how the work activities in the project is organized. As the name proposes it’s an analysis of a project to further suitable smaller tasks. WBS is hierarchical in nature and typically can be broken down according to functionality
  12. To design the WBS for your project make sure to first classify the main activities and deliverables. After executing this step starts the breakdown of the deliverables into sub-activities and creates the branches. And continuous the second step until you go to the activities where they are manageable.

Gantt chart

  1. The Gantt chart, in its modern form which includes task dependencies, is used to create the project schedule. Each project work packages and activity is now effect by the working calendar (hours and days per week for work is actually done), the allocated resources, how much of the working time each resource dedicates to that work package.
  2. The Gantt Charts is defined as the planning of the project tool that is used to represent the timing of tasks required to complete a project because Gantt Charts are easy to comprehend and easy to design, Gantt charts are used by many project managers all but mostly for complex projects.
  3. The Gantt chart is a timeline focused on and shows you when things should be or will be done.
  4. The Gantt chart focuses is on “When”. Mean then the specific activities should be complete.
  5. Also, the Gantt chart is defined as the Graphical representation of a sequence of activities. Which is a Bar Chart with logical linkages.
  6. Gantt chart visually shows the duration of the task.
  7. Every project comprises many tasks, milestones, and events. This Gantt chart is a crucial tool to demonstrate all these elements through the timespan and also show how they are related to each other.
  8. Gantt chart is also known as the timeline is the graphical view tasks in the project shown as bars in a time graph.
  9. The Gantt chart shows us graphically the start and end date of the project with sub-activities timespan in a horizontal bar which is displayed over a span of time like days, weeks, or months.
  10. A Gantt chart is a tool to design a project schedule. And the schedule is defined as the arrangement of each activity of the project on the basis of the calendar. To show when specific activities should be performed.
  11. A Gantt chart is a visual timeline of the project. It shows the sequence of work, dependencies between tasks when they are delivered, etc.
  12. A Gantt chart is designed from the WBS and known as the bar chart that tracks tasks across time. It tells us about the start and finished date of each task and their relationship with each other. It also shows us the percentages of the project is completed. A timeline or Gantt chart demonstrates the critical path, which is the longest duration path of the project network diagram.

If one task of the critical path is delayed the whole project would be delayed because the slack is zero on the critical path. Microsoft Project is the best-known tool for designing Gantt charts.
