Following three years of revision work the latest edition of ISO 9001 quality management systems standard has been published. The 2015 edition is evolution rather than revolution and is less prescriptive, focussing on managing processes and less on documentation. This has been achieved by combining the process approach with risk-based thinking, and employing the Plan-Do-Check-Act cycle at all levels in the organization. It is designed to be a solid base and easily integrated with other standards. ISO 9001:2015 replaces previous editions and certification bodies will have up to three years to migrate certificates to the new version.
