ISO 9001 is an international standard for quality management systems (QMS). It provides a set of requirements for organizations to follow to ensure that they are consistently providing products and services that meet customer and regulatory requirements. Organizations can be certified to ISO 9001, demonstrating to customers and other stakeholders that they have a robust and effective QMS.

ISO 9004 is a set of guidelines for performance improvement that organizations of any type or size can use. It provides a framework for organizations to improve their performance to meet their goals and objectives continuously, and it is not a certification standard. It provides guidance on various aspects of performance improvement, such as leadership, customer focus, and process management.
Can an organization be certified to both ISO 9001 and ISO 9004?
An organization can be certified to ISO 9001, but it cannot be certified to ISO 9004 as it is not a certification standard. ISO 9004 is a set of guidelines for performance improvement, and it does not have a certification process. However, an organization can use the guidelines provided in ISO 9004 to improve its performance and to complement its QMS based on ISO 9001. ISO 9004 can be used as a framework for continuous improvement and as a guide for the organization to understand how to improve its business performance and competitiveness.
