The totality of activities required to provide cost-effective support to software.

The identification of the configuration of a system at distinct points in time for the purpose of systematically controlling changes to the configuration, and maintaining the integrity and traceability of the configuration throughout the system life cycle.

The computer-based tools that are intended to assist the software life cycle processes and the methods which impose structure on the software engineering activity with the goal of making the activity systematic and ultimately more likely to be successful.

The dynamic verification of the behavior of a program on a finite set of test cases, suitably selected from the usually infinite executions domain, against the expected behavior.

The degree to which a set of inherent characteristics fulfills requirements.
