The term network logic would appear to be defined by the simplest of concepts. The logic that goes into the actual building of the schedule network path. And in some ways it really is that simple. It all boils down to a fundamental component. The fundamental path that the whole thing must follow. However, there is a little bit more to it than just that. Specifically, the project’s specific network logic as dictated and pre-determined by the project management team and or the project management team leader refers to and represents the particular collection of schedule activity dependencies that exists for the purpose of making up the entirety of the project schedule network diagram. Determining the direction and foundations of the network logic early and often is imperative to the smooth work flow throughout the life cycle of the project.
This term is defined in the 3rd and the 4th edition of the PMBOK.
