Validation vs. Verification in Software Testing

During software testing, it is essential to understand the distinction between validation and verification:

Verification:

Verification is the process of evaluating whether the software product meets the specified requirements and is implemented correctly. It focuses on ensuring that the software is built according to the design specifications and standards.

Validation:

Validation, on the other hand, is the process of evaluating whether the software meets the customer's needs and expectations. It involves checking whether the software fulfills its intended purpose in the real world environment.

Difference Summary:

• Verification checks if the software is built correctly, while validation checks if the right product is built.
• Verification is a process-oriented activity, focusing on the development phase, while validation is product-oriented, focusing on the end product.
• Verification answers "Are we building the product right?" and validation answers "Are we building the right product?"

By understanding and implementing both verification and validation processes, software testing professionals can ensure the quality and reliability of the software product.
