ISO 9001 is based on seven quality management principles that shape a company's approach to quality. These include: customer focus, leadership, engagement of people, process approach, improvement, evidence-based decision making, and relationship management. Each principle is essential for developing a robust and effective QMS. For instance, customer focus ensures that customer satisfaction drives improvements, while leadership provides direction and purpose. By applying these principles, businesses can better align their processes with strategic goals, strengthen stakeholder relationships, and consistently deliver high-quality outcomes. Understanding and integrating these principles is critical to successful ISO 9001 implementation.
