Verified

Verified

Verification and Validation are independent procedures that are used together for checking that a product, service, or system meets requirements and specifications and that it fulfills its intended purpose. These are critical components of a quality management system such as ISO 9000. The words "verification" and "validation" are sometimes preceded with "Independent" (or IV&V), indicating that the verification and validation is to be performed by a disinterested third party.

It is sometimes said that validation can be expressed by the query "Are you building the right thing?" and verification by "Are you building it right?"

In practice, the usage of these terms varies. Sometimes they are even used interchangeably.

The PMBOK guide, an IEEE standard, defines them as follows in its 4th edition:

  • "Validation. The assurance that a product, service, or system meets the needs of the customer and other identified stakeholders. It often involves acceptance and suitability with external customers. Contrast with verification."
  • "Verification. The evaluation of whether or not a product, service, or system complies with a regulation, requirement, specification, or imposed condition. It is often an internal process. Contrast with validation."

Famous quotes containing the word verified:

    In the course of a life devoted less to living than to reading, I have verified many times that literary intentions and theories are nothing more than stimuli and that the final work usually ignores or even contradicts them.
    Jorge Luis Borges (1899–1986)

    To regard the successful experiences which ensue from a belief as a criterion of its truth is one thing—and a thing that is sometimes bad and sometimes good—but to assume that truth itself consists in the process by which it is verified is a different thing and always bad.
    William Pepperell Montague (1842–1910)

    Don Pedro. Officers, what offence have these men done?
    Dogberry. Marry, sir, they have committed false report; moreover they have spoken untruths; secondarily, they are slanders; sixth and lastly, they have belied a lady; thirdly, they have verified unjust things; and, to conclude, they are lying knaves.
    William Shakespeare (1564–1616)
