Program Evolution Models


Reference /Scacchi, 2001/ Process Models in Software Engineering
In contrast to the preceding four prescriptive product development models, Lehman and Belady sought to develop a descriptive model of software product evolution. They conducted a series of empirical studies of the evolution of large software systems at IBM during the 1970's /Lehman, 1985a/. Based on their investigations, they identify five properties that characterize the evolution of large Software system (see Laws of the software evolution).

However it is important to observe that these are global properties of large software systems, not causal mechanisms of software development.

Rationales The author classifies Program Evolution Models as one of the Software Product Development Model
