Which principle involves making decisions based on data and evidence according to ISO 9000 standards?

The principle that emphasizes making decisions based on data and evidence according to ISO 9000 standards is the principle of evidence-based decision making. This principle underscores the importance of leveraging accurate and relevant data to guide decision-making processes. By relying on evidence, organizations can ensure that their decisions are grounded in reality rather than assumptions or opinions, which can enhance the effectiveness of their strategies and processes.

This approach fosters a systematic analysis of information and encourages organizations to understand the cause-and-effect relationships in their operations. It also allows for more predictable outcomes and helps in continual improvement, as decisions can be measured and validated against concrete data.

In contrast, while the principle of process approach focuses on managing interrelated processes to achieve desired outcomes, and the engagement of people centers around involving staff in operations for better outcomes, these principles do not specifically address the reliance on data and evidence in decision-making. The principle of leadership pertains to the role of leaders in providing direction and engaging employees, but again, it does not directly relate to making data-driven decisions.
