The Project Management Network Diagram – An Example

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. Read the Complete Article

Network Diagrams

Network Diagrams (#11 in the series How to Plan and Organize a Project)
By Michael D. Taylor

A project network diagram is a flow chart depicting the sequence in which a project’s non-summary activities (“terminal elements”) are to be completed, showing all their dependencies.

The network diagram is excellent for planning and replanning project activities sequencing, and it also identifies the project’s critical path. Upon completing the construction of the network diagram, the activities which represent the longest path from project start to project end, are identified. That means if any of these critical path activities slip, so does the project completion date.

He is principal of Systems Management Services, and has conducted project management training at the University of California, Santa Cruz Extension in their PPM Certificate program for over 13 years, and at companies such as Sun Microsystems, GTE, Siemens, TRW, Loral, Santa Clara Valley Water District, and Inprise.

Project Planning Process – Network Diagrams

Project Planning Process – Network Diagrams (#6 in the Hut A Quick Guide to Project Management)
By Manjeet Singh

The WBS allowed you to identify groups of activities that you need to accomplish in your project. However, the WBS does not show the dependencies or sequence between these activities. A network diagram will allow you to illustrate this. Once your network diagram is ready, only then can you realistically start determining your project’s schedule.

Here is a simplified network diagram for the “Build Shed” project:

Example Network Diagram

The above network diagram shows the relationships (arrows) between the main activities (rectangles) that are required to build a shed. You can flesh out the following information from the above diagram:

  • The Cut wood activity can be carried out in parallel to the Build shed base & Supervise cement hardening ones – this of course assumes that you have different teams working on each set of activities.

Managing the Project Time – The Official Approach (How It Looks on Paper)

Managing the Project Time – The Official Approach (How It Looks on Paper) (#2 in the series Managing the Project Time)
By Joseph Phillips

In the perfect project-management world, which doesn’t exist, there is a logical, practical approach to calculating how long a project should take to complete. Let’s pretend that we’re living in this perfect project management world and see how things should go.

First we work with the customer to define the product scope—describing the thing that they want us to create. Then we create the project scope—all of the required work and only the required work to create the product scope. And then, boy oh boy, we create the work breakdown structure (WBS).

The WBS is not a list of the activities to complete the project. That’s right. The WBS is a deliverables-oriented decomposition of the project deliverables—not the project work. Once we’ve created the WBS, we can generate a list of the activities that the project team will need to perform to create the identified deliverables. Read the Complete Article

Critical Path Mapping with Activity Network Diagrams

Critical Path Mapping with Activity Network Diagrams
By Steven Bonacorsi

The activity network diagram is a method of displaying the timelines of all the various subtasks that are involved in any project. By doing this, the total task duration and the earliest and latest start and finish times for each task are also calculated and displayed. In addition to showing which subtasks are critical to on-time task completion, the activity network diagram can help determine where extra effort to speed a subtask will have the greatest payoff to overall speed.

The activity network diagram has had a relatively long history, dating back to the 1930s. In the 1950s, the technique emerged as the Program Evaluation Research Technique (PERT) and as the Critical Path Method (CPM). There are several ways to represent the output of the PERT/CPM process.

The method called the activity-on-arrow or, more simply, the arrow diagram will be reviewed in this article. Read the Complete Article
