Computer System Validation (CSV) refers to the process of ensuring that a computer system operates in a manner that meets all specified requirements for intended use. This involves a series of activities, including testing, documentation, and verification, to demonstrate that the system performs accurately, securely, and consistently. It applies to various systems, such as those used in manufacturing, clinical trials, laboratory testing, and regulatory reporting. The ultimate goal is to ensure the system's functionality is aligned with its intended purpose and meets regulatory guidelines.
