- Create the WBS using Microsoft Project.
- Draw the Gantt chart diagram.
- Note that the above lists, though extremely useful, are difficult to comprehend instantly. This is because the brain does not handle large quantities of information well. On the other hand, the brain does deal very well with images. This is the main reason that network diagrams are worth developing and are so commonly used. They present a graphical view of the project that we can easily comprehend. If we graphically show all this information, we could construct an Activity-On-Node Diagram.
- Draw the network (Activity-On-Node) diagram.
- Calculate the ES, EF, LS, LF, and S for each activity.
- Find the project's critical path.
- Find the project's critical time.
