A time-scaled schedule network diagram is essentially a diagram that is used in project management whenever you are scheduling an activity. As such, it can be reduced to even simpler terms in saying that a Time-Scaled Schedule Network Diagram is a “fancy” term that is used whenever someone is talking about a project schedule. However, this diagram does need to be drawn in a rather specific manner in order to be understood by those who are in project management. This manner will show just how the project management team should position the project and how long the activity should take, from the very beginning to the very end of the procedure. Now that you understand what a Time-Scaled Schedule Network Diagram and what information it should include, you should also know that this diagram does need to be drawn in a specific manner. It needs to be drawn in the form of a bar chart. However, there is a very specific type of bar chart you will want to use. It must include a schedule for network logic. As such, all diagrams will be uniform, which is what is desirable so that everyone can understand what is taking place.
This term is defined in the 3rd and the 4th edition of the PMBOK.
