Dans le domaine de l'Assurance Qualité et du Contrôle Qualité (AQ/CQ), l'accent est souvent mis sur la garantie de la qualité initiale des produits et services. Cependant, il existe un autre aspect crucial qui mérite une attention égale : la **maintenance**. L'**Assurance Qualité de la Maintenance (AQM)** joue un rôle essentiel pour garantir que les produits, les équipements et les systèmes conservent leur fonctionnalité et leur sécurité tout au long de leur durée de vie.
**Qu'est-ce que l'Assurance Qualité de la Maintenance ?**
L'AQM est une approche systématique pour garantir que les **activités de maintenance** - comprenant des tâches telles que les réparations, les révisions, les reconstructions, les modifications et la récupération - **conforment aux exigences techniques prescrites**. Il s'agit de garantir que l'actif entretenu fonctionne comme prévu, répond aux normes de performance et reste conforme aux réglementations de sécurité.
**Pourquoi l'AQM est-elle importante ?**

Conclusion :
L'AQM est un élément essentiel de l'assurance qualité globale, jouant un rôle vital pour garantir la fiabilité, la sécurité et la performance à long terme des actifs. En intégrant l'AQM dans leurs opérations, les organisations peuvent minimiser les coûts, améliorer l'efficacité et maintenir une solide réputation pour la fourniture de produits et services de haute qualité.
