The key differences between the two First, there is a graphical difference: PERT charts are diagram charts while Gantt charts are bar charts. Then, there is a difference in purpose: a PERT chart focuses on the dependency of relationships between tasks while a Gantt chart focuses on the time required to complete a task.
Full Answer
The difference between them is that a PERT chart is a kind of network diagram, while a Gantt chart is a bar chart. What is the PERT Chart? PERT Chart is an acronym for (Program Evaluation and Review Technique). A PERT chart is a project management tool used to schedule, organize, and coordinate tasks within a project.
Feb 18, 2022 · The components in the PERT chart are critical path, responsibilities, project duration, while the Gantt chart does not show the critical path. The PERT chart is used to track the whole project, while the Gantt chart is used to track the progress of the subdivided tasks from the main project. Gantt Chart PERT Chart Represented with Bar Chart
Aug 06, 2018 · Another difference is that the Gantt chart is a top-down approach, while the PERT/CPM chart is bottom-up. The Gantt chart organizes tasks in an easy to read format with status bars easily decipherable, while the PER/CPM chart is often massive and hard to sort out when there are many dependencies in a project.
Then, there is a difference in purpose: a PERT chart focuses on the dependency of relationships between tasks while a Gantt chart focuses on the time required to complete a task. The time to use each chart also varies: a PERT chart is preferable at the beginning of the project as it allows to plan for its duration while a Gantt chart is better used during the project since it is easier to …
A Gantt chart is a bar chart with the x-axis and y-axis representing tasks in a timeline. A PERT chart is a flow chart or network diagram that displays project tasks in boxes and links them with arrows that outline dependencies.Feb 25, 2021
Both of these charts are used for task scheduling, controlling, and administering the tasks necessary for the completion of a project. The difference between them is that a PERT chart is a kind of network diagram, while a Gantt chart is a bar chart.
The main difference between a Gantt chart and a critical path analysis is that a Gantt chart offers a timeline view of a project, whereas a critical path maps the sequence of scheduled tasks that determine a project's duration.Dec 11, 2020
PERT charts are challenging to change mid-project, making them a less flexible option. Gantt charts offer more options if a project or plan changes at any point along the way. Using a PERT chart allows team members to quickly see which tasks are dependent on each other and who is responsible for what.Dec 23, 2021
A work breakdown structure (WBS) is a diagram that shows what a project will achieve or build, including project scope. A Gantt chart is a visual that uses bars to illustrate the timeline of the project activities.Dec 8, 2021
A Gantt chart is a project management tool that illustrates a project plan. It typically includes two sections: the left side outlines a list of tasks, while the right side has a timeline with schedule bars that visualize work.
PERT is a project management technique, whereby planning, scheduling, organising, coordinating and controlling uncertain activities are done. CPM is a statistical technique of project management in which planning, scheduling, organising, coordination and control of well-defined activities take place.
Gantt charts use horizontal bars across a linear representation of time to show the duration of tasks graphically, whereas network diagrams use basic flow-charting tools to represent graphically the tasks through a workflow.Sep 26, 2017
A Gantt chart is a graphical representation of activity against time. A Gantt chart is a project management tool assisting in the planning and scheduling of projects of all sizes, although they are particularly useful for simplifying complex projects.
Project network diagram As an alternative to Gantt charts, project network diagrams are used to scope a project and determine your project's critical path. The critical path is the longest path in your diagram use to help you determine how long the project will take.
When compared to PERT charts, Gantt charts are more useful for depicting the activities associated with large projects. Gantt charts visually show the time overlap of tasks whereas PERT does not show time overlap but does show which tasks could be done in parallel.
A Gantt chart is a graphical depiction for planning and scheduling projects. It breaks a project into smaller pieces of tasks with each of these spread out over time. With it, you can see task dependencies, scheduling constraints, duration of each task and percent complete.
However, they differ from each other in many aspects. One of the differences is that the Gantt chart is more straightforward than the Pert chart.

The Gantt chart is a graphical representation of the timing of your project’s work packages and tasks as well as deliverables and milestones. Its main purpose is to show how the different project’s items are planned in time, but it also shows the links between them. To design a Gantt chart, list all the items (work packages, tasks, ...
Let’s review together the differences between the two and how to draw them. The Gantt chart was created by Henry Gantt in 1917 and is still today a widely used tool in project management. The Gantt chart is a graphical representation of the timing of your project’s work packages and tasks as well as deliverables and milestones.
PERT is an acronym that stands for Program Evaluation and Review Technique and was developed by the US Navy in the 1950s. It is a graphical representation of the links between tasks represented as a network. It does not show directly the timing of each task.
A Gantt chart is a horizontal bar chart developed as a production control tool in 1917 by Henry Charles Gantt, an American Engineer and Social Scientist. The Gantt chart is commonly used in project management to provide a graphical illustration of a schedule that help to plan, coordinate, and track specific tasks in a project.
Program Evaluation Review Technique (PERT) Chart also referred to as PERT Diagram is a project management tool used to schedule, organize and coordinate tasks within a project.
Both of these charts are used by project managers and help in displaying the tasks which are required for project completion.
The difference between them is that a Gantt chart is basically a bar chart and a PERT chart is a flow chart. The Gantt chart was first developed and introduced by Charles Gantt in 1917. It deals with the sequence of tasks needed to complete the project. In this chart, each horizontal bar represents a task.
A PERT chart stands for “Program Evaluation and Review Technique” chart. Both of these charts are used by project managers and help in displaying the tasks which are required for project completion. The charts are used for task scheduling, controlling, and administering the tasks necessary for completion of a project.
Program Evaluation and Review Technique charts were developed and introduced in 1950 by the U.S. Navy. They were developed to manage large projects which had complex tasks and a very high intertask dependency. The charts have an initiation node, and the initiation node later branches into many networks of tasks.
