Quality is becoming increasingly important as a competitive factor, as the market success of products depends on how well a market participant can adapt to the needs of a specific customer group and satisfy them. The concept of quality does not merely refer to compliance with product specifications, but encompasses all requirements set by both internal and external customers. The central success factor is the customer. Companies that are strictly customer-oriented are demonstrably more successful than the industry average. However, despite the importance of the quality factor, many companies face the challenge of holistic implementation within the organization. There are various tools available to improve quality, but a unified strategy to connect all individual aspects is lacking.
