The work of software maintenance is divided into 4 basic tasks
Still talking about maintenance of source code, a study that has greatly influenced the software engineering community classified by analyzing the results of questionnaires the main practices of software maintenance. Four practices were identified:
a) Improvement: Involve changes in functionality
b) Adaptative: Changes in the environment are adapted to the requirements
c) Corrective: Activities for error correction
d) Preventive: Improvements to avoid future problems
