Rigorous Software Quality Assurance
摘要
Verification and Validation, often abbreviated as V&V, represent two of the most essential activities associated with well-engineered systems within the practice of systems engineering. In the context of software-intensive critical systems, these activities form the foundation of confidence that a system will perform safely, securely, and reliably in the environment for which it is intended. According to INCOSE, verification is the process of determining that the system has been built correctly in accordance with its specified requirements, while validation ensures that the right system has been built to satisfy the intended mission and stakeholder needs [1]. When either discipline is neglected, the result can be catastrophic. In critical systems such as command-and-control networks, autonomous defense platforms, nuclear monitoring systems, and medical device software, even a single undetected defect can lead to operational paralysis or the loss of human life. For this reason, verification and validation must not be treated as final project activities but as continuous and integral elements of the entire system lifecycle.
