Software Quality Engineering (SQE) is a process that evaluates, assesses, and improves the quality of software.
Software quality is often defined as the degree to which software meets requirements for reliability, maintainability, transportability, etc., as contrasted with functional, performance, and interface requirements that are satisfied as a result of software engineering.
Quality must be built into a software product during its development to satisfy quality requirements established for it. SQE ensures that the process of incorporating quality in the software is done properly, and that the resulting software product meets the quality requirements. The degree of conformance to quality requirements usually must be determined by analysis, while functional requirements are demonstrated by testing. SQE performs a function complementary to software development engineering. Their common goal is to ensure that a safe, reliable, and quality engineered software product is developed.
