In software engineering, the laws of software evolution refer to a series of laws that Lehman and Belady formulated starting in 1974 with respect to software evolution. [1] [2] The laws describe a balance between forces driving new developments on one hand, and forces that slow down progress on the other hand. Over the past decades the laws ...
From 1964 to 1972 he worked at IBM's research division in Yorktown Heights, NY where he studied program evolution with Les Belady. The study of IBM's programming process gave the foundations for Lehman's laws of software evolution. [8] In 1972 he returned to Imperial College where he was Head of Section and later Head of Department (1979–1984).
IFOSS L. Rev. was intended to provide a neutral forum for debate and analysis of legal issues connected with Free and Open Source Software. Articles were subject to peer review where appropriate [ 2 ] and the editors exercise a policy of independence from sponsors and facilitators.
Manny Lehman used the term entropy in 1974 to describe the complexity of a software system, and to draw an analogy to the second law of thermodynamics. Lehman's laws of software evolution state that a complex software system will require continuous modifications to maintain its relevance to the environment around it, and that such modifications ...
Software evolution is the continual development of a piece of software after its initial release to address changing stakeholder and/or market requirements. Software evolution is important because organizations invest large amounts of money in their software and are completely dependent on this software.
The idea of linking software complexity to software maintainability has been explored extensively by Professor Manny Lehman, who developed his Laws of Software Evolution. He and his co-author Les Belady explored numerous software metrics that could be used to measure the state of software, eventually concluding that the only practical solution ...

Software law refers to the legal remedies available to protect software-based assets. Software may, under various circumstances and in various countries, be restricted by patent or copyright or both. Most commercial software is sold under some kind of software license agreement. [1]
