PERT Chart vs Gantt Chart Differences. PERT charts: Utilized before a project begins to plan and determine the duration of each task. Gantt charts: Used while a project is happening to break projects into smaller tasks and highlight scheduling constraints. When you and your team need to complete a project, you’ll realize that there are dozens of diagrams you could use for project management. Gantt chart is defined as the bar chart. PERT chart is similar to a network diagram: Gantt chart was developed by Henry L. Gantt. PERT chart was developed by the United States navy. Gantt chart is often used for Small Projects: PERT chart can be used for large and complex Projects: Gantt chart focuses on the time required to complete a task PERT vs Gantt Chart：How to Choose Both Pert charts and Gantt charts are useful tools for project managers to visualize the whole projects. 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. How to choose appropriate charts for different projects? Another difference between a PERT and Gantt chart is that PERT charts can operate at multiple nesting levels: A top-level diagram shows the major tasks and lower-level diagrams show the sub-tasks associated with a task. This provides an easy method to add or remove sub-tasks without disturbing the top-level diagram. Further in this video, we have also discussed the definition of PERT along with its chart. Likewise CPM is explained here. the video ends with a comparison chart which explains the difference
PERT charts are similar to the critical path method (CPM) which identifies the longest path through the project, and therefore the minimum time for the project to be.
PERT chart vs GANTT chart-Difference between PERT chart and GANTT chart. In Critical Path Method(CPM) the activity durations are based on historic data which has been performed many times. Think of a situation wherein activity is not performed earlier and it has been performed first time in the organization. This is the time PERT is useful. Critical Path Method (CPM) charts are similar to PERT charts and are sometimes known as PERT/CPM. In a CPM chart, the critical path is indicated. A critical path consists that set of dependent tasks (each dependent on the preceding one), which together take the longest time to complete. Free project management guide that talks about Gantt Chart vs PERT Chart, with Gantt Chart example, Gantt Chart tool and PERT examples and tools. not show clear dependencies or relationships between tasks and also fails to provide enough information for showing the critical path and as well as the detail information for each of the activities. Critical & Non-Critical Path : Gantt charts do not display the critical and non-critical tasks. PERT charts clearly display critical and non-critical tasks. Percentage Of Completed Task: In Gantt charts, the focus is on the percentage completion of each task, without demonstrating the link that two tasks may have to each other. The Gantt chart was first developed and introduced by Charles Gantt in 1917. Program Evaluation and Review Technique charts were developed and introduced in 1950 by the U.S. Navy. 06. Gantt charts are straightforward and are not made for projects which need changes: PERT charts are complex and are made for small portions of the project. 07. Gantt chart is a tool which is useful in scheduling the various activities of a project in the form of horizontal bar graph where as CPM provides a graphical view and network of events and
2.Gantt charts focus on the time required to complete a task; whereas a PERT chart focuses on intertask relationships. Gantt has linear representations or it is a bar chart; whereas a PERT chart is a flow chart and has parallel networks of individual tasks.
Gantt charts and PERT charts are visualization tools that project and States Navy in the 1950s and are commonly used with the critical path method (CPM). Critical Path Method (CPM), Critical Path Scheduling (CPS) and Gantt chart scheduling project using graphical tools such as PERT/CPM and Gantt chart.

There are a number of scheduling techniques. We'll focus on two of the most common: Gantt and PERT charts. PERT network chart for a seven-month project with five milestones (10 through 50) and six activities (A through F). The program (or project) evaluation and review technique (PERT) is a statistical tool used in PERT and CPM are complementary tools, because "CPM employs one time estimation and one cost estimation for
