ISO 9000 – Quality management
The ISO 9000 family addresses various aspects of quality management and contains some of ISO’s best known standards. The standards provide guidance and tools for companies and organizations who want to ensure that their products and services consistently meet customer’s requirements, and that quality is consistently improved.
ISO 9001:2015 sets out the criteria for a quality management system and is the only standard in the family that can be certified (although this is not a requirement). It can be used by any organization, large or small, regardless of its field of activity. In fact ISO 9001:2015 is implemented by over one million companies and organizations in over 170 countries. This standard is based on a number of quality management principles including a strong customer focus, the motivation and implication of top management, the process approach and continual improvement. These principles are explained in more detail in the pdf Quality Management Principles. Using ISO 9001:2015 helps ensure that customers get consistent, good quality products and services, which in turn brings many business benefits.
AUDITS (third party)
Certification involves auditing by a third party to check that the system functions effectively and meets ISO 9001 standards. An organization must perform internal audits to check how its quality management system (QMS) is working. An organization may decide to invite an independent certification body to verify that it conforms to the standard, but there is no requirement for this.
