Main quote from Wikipedia concerning iso9000 council:

ISO 9000 is a family of standards related to quality management systems and designed to help organizations ensure that they meet the needs of customers and other stakeholders.^[1] The standards are published by ISO, the International Organization for Standardization, and available through National standards bodies. ISO 9000 deals with the fundamentals of quality management systems,^[2] including the eight management principles^[3][2]) on which the family of standards is based. ISO 9001 deals with the requirements that organizations wishing to meet the standard have to fulfill.^[4]

Third party certification bodies provide independent confirmation that organizations meet the requirements of ISO 9001. Over a million organizations worldwide^[5] are independently certified, making ISO 9001 one of the most widely used management tools in the world today. Despite widespread use, however, the ISO certification process has been criticized^[6][7] as being wasteful and not being useful for all organizations.^[8][9][10]
