The Project Management Network Diagram – An Example
By Brian Denis Egan, B.Sc, M.Sc., M.B.A., PMP – Global Knowledge Course Director

The PM Network Diagram includes the same information in the PMBOK Process Groups and goes several steps further. The 44 processes are listed. In addition, relationships between processes are illustrated.

The figure below is a comprehensive example of the Project Management Network Diagram:

Information in black is the same as it appears on the PMBOK chart. Red, Green, and Blue printing have been used to indicate supplemental information.

In red are Inputs to a process. Inputs are the information that must be available in order for a process to be completed.

In blue (under the process name) are Tools and Techniques. These are the steps and practices that are necessary to complete a process.

In green are the Outputs. Outputs are the reason that a process is performed. They are the purpose of a process.

Arrows are used to show relationships between processes. The outputs of one become the inputs of another. What a process needs (inputs), how it is performed (tools and techniques), and what the point is (outputs) are what you need to know to pass the PMP Exam.

The PM Network Diagram summarizes and illustrates what the PMBOK and training manuals take 500 pages to say.
