What term refers to the deviation of a component or system from its expected delivery or result?

The term that refers to the deviation of a component or system from its expected delivery or result is "Failure." In the context of software testing and quality assurance, a failure occurs when the system behaves in a way that is different from the specified requirements or expectations. This could mean that the system produces incorrect results, does not perform tasks as specified, or fails to meet user needs.

Understanding failures is crucial in testing processes, especially in Agile environments, as it helps teams quickly identify and address issues, ensuring the product meets the desired quality standards. By focusing on the analysis of failures, teams can improve their processes and ultimately enhance the reliability and performance of the system being developed.

The other terms listed do not capture this concept as accurately. Finding refers to any defect or issue identified during testing, but it does not specifically indicate a deviation from expected results. Interoperability involves the ability of different systems to work together effectively, which is not directly related to the outcome of a single component or system. Functionality describes the specific features or capabilities of a software product but does not inherently express the notion of deviation from expected results.
