"Nem lesz szükséged rá", "You aren't gonna need it"^[1]^[2] (YAGNI)^[3] egy elv az extrém programozáson (XP) belül ami kimondja, hogy egy programozónak nem kell funkciókat készíteni amíg azok nincsenek szükségesnek ítélve.^[4] XP társ-feltalálója Ron Jeffries írta: "Mindig implementáld a dolgokat amikre szükséged van, de soha hogyha csak sejted hogy szükséged lesz rá."^[5] Más megfogalmazásban ez a kifejezés tartalmazza, hogy "Nem lesz rá szükséged" ^[6]^[7] és "Nem fog kelleni neked".^[8]

Összefüggés

YAGNI az egy elv ami az XP mögött áll, hogy "Csináld a legegyszerűbb dolgot amit csak tudsz" (DTSTTCPW).^[2]^[3] Ez számos más gyakorlattal kombinálva terveztetett használni, mint például a refaktorálás, folyamatos automatizált unit tesztelés, és folytonos integráció. Folytonos refaktorálás nélkül használva, rendezetlen kódhoz és masszív újra dolgozáshoz vezethet. YAGNI függősége a gyakorlatok támogatásán, része az XP eredeti definíciójának.
