Enactable models for quantitative evolutionary software processes

Software engineering is distinct from programming methodology but additional assumptions may lead to a useful interpretation of an "execution mechanism" and corresponding process programs. This paper reports experiences with quantitative evolutionary software processes in which procedural process programs were used to control the development of routine process-control software. The paper presents a pragmatic viewpoint. We took the evolutionary approach to attain change locality and avoid diseconomies of scale. Our functional requirements domain was stabilised and parametrised so that a non-functional quantitative approach could have been taken.
