Once you’ve made the final design, think about type. Different fonts can emphasize parts of the diagram and make it easier to read. A legend or key in the corner will also help the reader understand.
How to take advantage of positives and avoid negatives of project network diagrams?
To take advantage of the positives and avoid the negatives of project network diagrams, it helps to know what works. For example, a network diagram is a visual language, and like any communicative method, it requires using symbols that are shared and universally understood.
Can you use a network diagram to represent a project schedule?
Using a network diagram software doesn’t guarantee that the network diagram will accurately represent your project schedule if the sequences of activities are not mapped out correctly. Some don’t believe in the necessity of a network diagram, that there are other tools that cover the same ground.
Can a network diagram be misleading?
Of course, there can be errors when making it or other unknown factors that can influence it outside of the data collected; all of this can make the network diagram misleading and potentially damaging to your project. Using a network diagram software doesn’t guarantee that the network diagram will accurately represent your project schedule if the sequences of activities are not mapped out correctly.
What is a network diagram?
