Validation VS Verification

Validation and verification are two fundamental processes in quality assurance and quality control, often used in the context of software development, but applicable to various domains. Here's the difference between them:

  1. Verification:

    • Verification answers the question, "Are we building the product right?"
    • It involves checking whether the software meets the specified requirements and whether it adheres to the standards and guidelines defined for its development.
    • Verification activities include reviews, inspections, walkthroughs, and testing at various stages of the development process.
    • The focus of verification is on ensuring that the software is being developed correctly according to the predetermined specifications and requirements.
  2. Validation:

    • Validation, on the other hand, addresses the question, "Are we building the right product?"
    • It involves evaluating whether the software fulfills the customer's needs and expectations and whether it solves the intended problem or provides the desired functionality.
    • Validation activities include user acceptance testing (UAT), beta testing, prototyping, and demonstrations to stakeholders.
    • The focus of validation is on ensuring that the software meets the user's actual needs and that it delivers value in the real-world context.

In summary, verification is about confirming that the software is being developed correctly according to the defined specifications and standards, while validation is about confirming that the software meets the user's actual needs and expectations and delivers the intended value. Both verification and validation are essential for ensuring the quality and success of a software product.
