The chemicals producer Buckman Laboratories has announced its certification to ISO 9001:2000 at its Memphis, TN and Cadet, MO Plants; from Quality Systems Registrars (QSR). About every five years, ISO standards are reassessed and any necessary revisions are made. Companies wishing to continue their ISO 9000 status must implement the revisions by December 2003. Some of the essential changes to the standards include a greater emphasis on top management’s involvement with the quality management system in several areas including planning, communication and management review. The new standard also requires more evidence of customer focus and on setting measurable quality objectives for product and processes.
