Dans le monde de l'Assurance Qualité (AQ) et du Contrôle Qualité (CQ), un terme crucial mais souvent négligé est LQ, qui signifie Qualité Limite. Bien qu'il ne soit pas aussi largement discuté que des concepts comme AQL (Limite de Qualité Acceptable) ou RQL (Limite de Qualité Rejetée), LQ joue un rôle essentiel pour garantir la qualité des produits et maintenir la satisfaction des clients.
Qu'est-ce que la Qualité Limite ?
La Qualité Limite fait référence au niveau de qualité acceptable le plus bas pour un produit ou un service spécifique. Elle agit comme un seuil, en dessous duquel le produit est considéré comme inacceptable et doit être rejeté. En substance, LQ définit les normes minimales qui doivent être respectées pour garantir que le produit répond aux exigences de qualité de base.
