The standard was developed by the International Organization for Standardization, a multi-national association of countries working toward worldwide quality assurance, based in Geneva, Switzerland. A company’s compliance with ISO 9001 identifies that the company adheres to recognizable standards of quality. ISO 9001 is recognized by over 100 countries around the world. The ISO 9001 standard was initially approved in 1987. The international organization is composed of representatives from each nation’s standards organizations. Standards are developed by an ISO Technical Committee and submitted to the governing council. Approval of this group is required before publication. Certification may be performed by any number of agencies including American National Standards Institute (ANSI), American Society for Quality (ASQ), Lloyd’s Register Quality Assurance (LRQA), Registrar Accreditation Board of the US (RAB) among others.
