Here are the seven Quality Management Principles according to ISO 9001:2015:

1. Customer Focus: Organizations depend on their customers, and therefore should understand current and future customer needs, meet customer requirements, and strive to exceed customer expectations.
2. Leadership: Leaders at all levels establish unity of purpose and direction of the organization. They create and maintain an internal environment in which people can become fully involved in achieving the organization’s objectives.
3. Engagement of People: People at all levels are the essence of an organization, and their full involvement enables their abilities to be used for the organization’s benefit.
4. Process Approach: A desired result is achieved more efficiently when activities and related resources are managed as a process.
5. Improvement: Improvement of the organization’s overall performance should be a permanent objective.
6. Evidence-Based Decision Making: Effective decisions are based on the analysis of data and information.
7. Relationship Management: An organization and its external providers are interdependent, and a mutually beneficial relationship enhances the ability of both to create value.

Implementing these principles can help organizations enhance their performance, increase customer satisfaction, and foster continuous improvement. They provide a framework for developing a quality management system that aligns with an organization’s strategic objectives and promotes a culture of quality throughout the entire organization.
