International Organization for Standardization evolved ISO 9000 series of standards in 1987. These are quality assurance system standards. First revision came in July 1994 and second revision on 15 December 2000. Henceforth, there will be only one standard i.e. ISO-9001:2000. These standards are customer oriented and focus on customer satisfaction by fulfilling the customers’ requirements. These are applicable to any manufacturing or servicing organization. Hence, these are the product neutral standards. These can be adopted by any organization be it large, medium, small, limited company, private limited company, partnership firms and proprietorship firms.
