Project network-related diagrams are the magical flowcharts that eincredibly project manager need to know and also love. As opposed to interacting a task setup via lengthy blocks of message, task netoccupational diagrams enable PMs to summarize their plans in one visual that have the right to be conveniently digested and also interpreted. When combined with the Critical Path Method (CPM), task network-related diagrams likewise assist recognize just how long a project will certainly take and also which tasks will certainly be the most necessary to finish on time.

Must-recognize details about job netoccupational diagrams

First, project network diagrams and work breakdown structures (WBS) are sisters that constantly gain mistaken as twins. They are not the same thing. While a WBS divides project deliverables into manageable pieces, a job netjob-related diagram takes those pieces and/or the jobs forced to finish them and also organizes them chronologically. In short, a work-related breakdown structure shows a entirety and its parts while a project network diagram reflects a sequence of events.

Since project netjob-related diagrams show chronology, PMs always attract them left to right, prefer analysis a book.

The powers that be recognize two styles for drawing job netjob-related diagrams. The initially format, activity on node, mirrors an occasion as a box, also known as a node. Arrows affix occasions together to display sequence. The second format, activity on arrow, mirrors occasions on the arrows that affix nodes. Of the two layouts, diagrammers typically usage task on node over task on arrowhead.


Other names for a project netoccupational diagram encompass task administration netoccupational diagram, job circulation diagram, job flow chart, task monitoring flow chart, and task administration procedure flow chart. “A climbed by any type of other name would certainly smell as sweet,” and task netoccupational diagrams by any kind of various other name are still fantastic productivity tools.

How to construct a task network diagram

Project network-related diagrams are indeed magical, yet they don’t construct themselves. These procedures should obtain you began.

1. Start with a predecessor table.

You could be reasoning, “Woah! I assumed this was around network diagrams, not tables!” Don’t worry—it is. Predecessor tables list all of the work in your job together with their prompt predecessors, tasks one should finish before founding an additional job. With this information, your netjob-related diagram will certainly fall appropriate into location.

Suppose you want to make lasagna. This might be your predecessor table (constructed in, of course):


2. Build the flowchart.

Drag a procedure box onto your canvas and also label it “Start.” Then, lay dvery own boxes for each of the work that does not have actually an prompt predecessor, tasks 1, 3, and also 5. These will connect to the begin box. Task 2 comes immediately after job 1, so put them cshed together and connect them. Continue to do this until every one of your tasks have actually been charted and associated. As you develop, remember that project netjob-related diagrams are read from left to right. Your flowchart will certainly look something favor this as soon as you finish:


If you desire, you might soptimal best here. But for additional magic, you can apply the Critical Path Method to determine exactly how long your job will certainly take and also which tasks are the a lot of important to complete on time.

3. Apply the Critical Path Method.

The finest means to understand the Critical Path Method is to usage it, so let’s not waste time pontificating.

First, go back to your task netoccupational diagram and also figure out how long each step will take.


Next off, recognize the start and end time for each task. All of the tasks instantly after “Start” will begin at minute 0. The jobs that follow will begin when their latest predecessor ends. For instance, alert that “layer lasagna” starts at minute 27 bereason boiling and draining noodles takes much longer than making red sauce and also mixing cheese.

You currently have actually a projected end time for making lasagna. Assuming that you deserve to perform three things at when, or that you invited some friends, it will take you 84 minutes. The critical course is the noodles. If preparing the noodles starts late or takes also lengthy, you will run behind schedule. On the other hand also, you have 18 minutes of flex time on the red sauce and 22 minutes of flex time on the cheese mixture.
