PPAP Nedir?<\/h2>\n

PPAP, AIAG (Automotive Industry Action Group) taraf\u0131ndan yay\u0131mlanan ve otomotiv sekt\u00f6r\u00fcnde seri \u00fcretim par\u00e7alar\u0131n\u0131n onay\u0131 i\u00e7in kullan\u0131lan s\u00fcre\u00e7tir. Amac\u0131; tedarik\u00e7inin m\u00fc\u015fteri tasar\u0131m ve spesifikasyon gereksinimlerini anlad\u0131\u011f\u0131n\u0131 ve \u00fcretim s\u00fcrecinin bu gereksinimleri belirlenen \u00fcretim h\u0131z\u0131nda s\u00fcrekli kar\u015f\u0131layabildi\u011fini g\u00f6stermektir. Yeni par\u00e7a, tasar\u0131m de\u011fi\u015fikli\u011fi, s\u00fcre\u00e7 de\u011fi\u015fikli\u011fi, alt tedarik\u00e7i de\u011fi\u015fikli\u011fi veya \u00fcretim yerinin ta\u015f\u0131nmas\u0131 gibi durumlarda PPAP yeniden istenir.<\/p>\n
