After major empirical studies, Lehman and Belady proposed that there were a number of ‘laws’ which applied to all systems as they evolved. There are sensible observations rather than laws.
NettetBased on a systematic and comprehensive literature review, in this article, we describe how and when the laws, and the software evolution field, evolved. We also address the current state of affairs about the validity of the laws, how they are perceived by the research community, and the developments and challenges that are likely to occur in … Nettetcontinue doing so.
