In 1987, the ISO 9000 QMS standards were first published in order to provide organizations with quality assurance and quality management (Calisir, 2007). However, its more advanced versions have been designed by revising in subsequent years. The first one of these revisions was published as the series of ISO 9000:1994 in 1994. The second revision was formed in the year 2000 and named as ISO 9001:2000. The changes in both two revisions are major. There have not been so major changes in the other revisions formed in different years.
