validation vs verification

Validation and verification are two related steps in ensuring a product or system works as intended. Verification asks, "Did we build the product correctly?" and checks if it meets specified requirements and design. Validation asks, "Did we build the right product?" and confirms whether the final product fulfills the actual needs and expectations of users. In simple terms, verification ensures correctness during development, while validation confirms the product is suitable for its intended purpose once complete. Both are essential for delivering reliable and effective solutions.
