La certification ISO 9001 - 2015

L'ISO 9001:2015 spécifie les exigences relatives au système de management de la qualité lorsqu'un organisme:

a) doit démontrer son aptitude à fournir constamment des produits et des services conformes aux exigences des clients et aux exigences légales et réglementaires applicables, et

b) vise à accroître la satisfaction de ses clients par l'application efficace du système, y compris les processus pour l'amélioration du système et l'assurance de la conformité aux exigences des clients et aux exigences légales et réglementaires applicables.

Toutes les exigences de l'ISO 9001:2015 sont génériques et prévues pour s'appliquer à tout organisme, quels que soient son type ou sa taille, ou les produits et services qu'il fournit.

Obtenir la certification ISO 9001:2015, c’est s’appuyer sur 8 principes de management :
• l’orientation client ;
• l’implication du personnel ;
• l’approche processus ;
• l’amélioration continue ;
• la gestion par approche système ;
• le leadership ;
• la prise de décision fondée sur des preuves ;
• le management des relations avec les parties intéressées.
