Another type of imposed requirement is accepted and agreed upon standards. Most industries have
some established standards for the products they produced. There are also standards for how processes are
performed. Possibly the most widely recognized authorities for establishing and maintaining standards are
the International Organization for Standardization (ISO) and the American National Standards Institute
(ANSI).71 In regard to TCM, the standards of most relevance are ISO 9000 (quality management systemsfundamentals
and vocabulary) and ISO 10006 (quality management guidelines to quality in project
management)..
