Abstract: By classifying programs according to their relationship to the environment in which they are executed, the paper identifies the sources of evolutionary pressure on computer applications and programs and shows why this results in a process of never ending maintenance activity. hawick united twitterNettet•The process of software evolution is driven by requests for changes and includes change impact analysis, release planning and change implementation. •Lehman’s laws, such as the notion that change is continuous, describe a number of insights derived from long-term studies of system evolution.
