Difference between verification and validation. In other words we can say that Verification is the process to ensure whether the product that is developed is right or not. Validation is the process of checking whether the specification captures the customer’s needs, while verification is the process of checking that the software meets the specification. It is also sometimes called acceptance or business testing. The difference is in the implementation, desired outcome and the phase of the process. Verification is the process where execution of code is not take place and hence it comes under static testing. They are used in software project management, software testing, and software engineering. Verification is the process of checking that the software meets the specification. Difference between verification and validation testing. The difference is in the implementation, desired outcome and the phase of the process. Difference Between Verification is to identify errors in requirement specifications & Validation is used to find the defects in the implemented in Tabular Form These include workmanship and quality control requirements for the organization. It is human based checking of documents and files. It involves testing of black box, white box, grey box etc. In very simpler terms (to avoid any kind of confusion), we just remember that Verification means the review activities or the static testing techniques and validation means the actual test execution activities or the dynamic testing techniques. These two steps are distinctly different, and important in a good design process. The words "verification" and "validation" are sometimes preceded with "independent", indicating that the verification and validation is to be performed by a disinterested third party.
