This standard applies to all software-based systems. It applies to systems and software being developed, acquired, operated, maintained, and/or reused [e.g., legacy, modified, Commercial-Off-the-Shelf (COTS), Government-Off-the-Shelf (GOTS), or Non-Developmental Items (NDIs)]. When conducting the test process, it is important to examine the software in its interactions with the other parts of the system. This standard identifies the system considerations that test processes and tasks address in determining system and software correctness and other attributes (e.g., completeness, accuracy, consistency, and testability), and the applicable resultant test documentation.
