Large-Scale Complex IT Systems (Ian Sommerville, Dave Cliff, Radu Calinescu,Justin Keen, Tim Kelly , Marta Kwiatkowska,John McDermid, and Richard Paige):
Complexity stems from the number and type of relationships between the system’s components and between the system and its environment. If a relatively small number of relationships exist between system components and they change relatively slowly over time, then engineers can develop deterministic models of the system and make predictions concerning its properties.
However, when the elements in a system involve many dynamic relationships, complexity is inevitable. Complex systems are nondeterministic,
