Confirmation, or validation, is the process of ensuring that a product, service, or system meets specified requirements and functions as intended. This step is crucial in various fields, including software development, engineering, and manufacturing, as it helps identify any discrepancies or issues before full-scale production or deployment. During confirmation, tests and evaluations are conducted to verify that the design specifications align with the final output. This process not only enhances quality but also builds trust among stakeholders, ensuring that the end result satisfies user needs and complies with relevant standards and regulations.
