Difference between network diagram and pert chart

What Are the Similarities and Differences Between PERT and CPM Networks? This is a project network diagram that illustrates the activity flow in the project. What's the difference between a PERT chart and a Gantt chart? Both of these tools can A PERT chart illustrates a project as a network diagram. The U.S. Navy  Key Differences Between Gantt Chart and Pert Chart. Gantt Chart. Pert Chart. Represented with Bar Chart. Represented with Flowchart (or Network Diagram). Let us see Difference between Gantt Chart vs Network Diagram in this topic. The main differences are: Gantt charts is a Stacked Bar Chart to represent Project 

The Program Evaluation and Review Technique (PERT) is a network model that The activities in the above diagram are labeled with letters along with the The difference in the latest and earliest finish of each activity is that activity's slack .

A Gantt chart is a tool used for project management. It is used to represent the timing of various tasks that are required to complete a project. A network diagram   PERT and Gantt charts are visualization tools that are often used in project management. 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 Critical Path Network or Method came out of Du Pont, while the PERT Network was a result of a project at the U.S. Navy. But that’s history, let’s dig straight into the similarities and differences between PERT and CPM networks. For accurate project scheduling, the critical path must be known Similarities 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.

Pert chart was initially developed to simplify the planning and scheduling of large and complex projects. Pert chart looks like a flowchart. It uses boxes and arrows to show the subtasks and their dependencies. Key Differences Between Gantt Chart and Pert Chart

Both these techniques establish the critical path in a schedule network diagram. However, both CPM and PERT use different approach to arrive at the critical path and activity duration estimates. The following blog post highlights difference Between CPM and PERT.
