ISO 9001 is an international standard that sets out the criteria for a quality management system (QMS). It is based on several quality management principles including a strong customer focus, the involvement of top management, a process approach, and continual improvement. ISO 9001:2015 is the latest version of this standard, focusing on risk-based thinking and greater alignment with organizational strategies. Essentially, it helps organizations ensure they meet the needs of customers and other stakeholders while meeting statutory and regulatory requirements related to the product or service they provide.
