Verification and validation are two important processes in the quality assurance of products, systems, and processes.
Verification refers to the process of checking that a product, system, or component meets specified requirements. This can involve activities such as reviewing design documentation, inspecting physical products, or testing prototypes. The goal of verification is to ensure that the product, system, or component has been designed and implemented correctly.
Validation, on the other hand, refers to the process of evaluating a system or component during or at the end of the development process to determine whether it satisfies the specified requirements. This can involve activities such as testing the system or component in a real-world environment, or conducting user acceptance testing. The goal of validation is to ensure that the system or component will perform as intended when it is deployed.
Both verification and validation are important steps in the quality assurance process, and they are often used together to ensure that a product, system, or process is of high quality and fit for its intended purpose.
