The essential difference is how the simulation time is advanced. Continuous systems modeling methods such as system dynamics always advance time with a constant delta. Since variables may change within any time interval in a continuous system, the delta increment is very small and time-dependent variables are recomputed at the end of each time increment. The variables change continuously with respect to time. Discrete modeling normally is event based. State changes occur in discrete systems at aperiodic times depending on the event nature, at the beginning and end of event activities.

Weinberg was working on his book at the same time that Abdel-Hamid and Madnick were working on theirs, unknown to each other. The day after Weinberg submitted his work to the publisher, he met Abdel-Hamid and realized they were working on parallel and complementary paths for years. Weinberg describes the relationship between the two perspectives as follows. He starts from the low end, so projects get stable enough so that the more precise, high-end modeling exemplified by system dynamics can be even more useful.

It also helps facilitate human understanding and communication of the process, but does not explicitly consider automated process guidance or automated execution support. Some system dynamicists stress that understanding of system behavior and structure is the primary value of system dynamics as opposed to strict prediction. As will be detailed in subsequent sections, software process modeling with system dynamics has been used in a large number of companies, governmental agencies 5 Abdel-Hamid’s model and book describe project dynamics for a single fixed process.
