Verifitseerimine ja valideerimine

Verifitseerimine ja valideerimine (lühendatult V&V) on sõltumatud protseduurid, mida kasutatakse koos kontrollimaks toote, teenuse või süsteemi vastavust nõuetele ja spetsifikatsioonidele ning ettenähtud otstarbele.^[1] Nad mõlemad on kvaliteedijuhtimissüsteemi, näiteks ISO 9000, kriitilised komponendid. Sõnadele "verifitseerimine" ja "valideerimine" eelneb mõnikord sõna "sõltumatu", mis juhib tähelepanu sellele, et verifitseerimise ja valideerimise peab läbi viima sõltumatu kolmas osapool. "Sõltumatu verifitseerimine ja valideerimine" võib lühendatud kujul olla tähistatud ka kui "SV&V" (inglise keeles IV&V).

Tegelikult ei pruugi verifitseerimise ja valideerimise määratlused kvaliteedijuhtimise terminitena olla alati järjekindlad. Mõnikord kasutatakse neid isegi vaheldumisi.^[2]^[3]^[4]

Elektri- ja Elektroonikainseneride Instituudi (IEEE) vastu võetud standard – PMBOK Guide (projektijuhtimise teadmuskogu juhend) – määratleb need oma 4. väljaandes järgmiselt:^[5]

"Valideerimine. Kinnitus, et toode, teenus või süsteem vastab kliendi ja teiste määratletud sidusrühmade vajadustele. Sageli eeldab see ka väliste klientide heakskiitu. Vastupidi verifitseerimisele."
"Verifitseerimine. Hinnang selle kohta, kas toode, teenus või süsteem vastab määrusele, nõudele, spetsifikatsioonile või kehtestatud tingimusele või mitte. Sageli on see sisemine protsess. Vastupidi valideerimisele."

There are some authors who apparently regard these two terms as synonymous, others who seem to be only vaguely aware of the differences. Some even appear to believe that V&V is one word! ... There is such a fundamental difference between these models that the term validation has many years ago been selected to be different from the term verification. Nevertheless, it is debatable whether the distinction between validation and verification should be continued.
