Does ISO 9001 certification bring value to organizations? You may think so, but the academic research shows mixed results. For example, researchers have found that ISO 9001 certification may not improve customer satisfaction and may simply cost organizations more money through paperwork (Heras-Saizarbitoria, Arana, & Boiral, 2015; Riillo, 2013). Other researchers found improvements across the board in companies that used an ISO 9001 QMS (Jain & Ahuja, 2012; Psomas & Pantouvakis, 2014). There is a gap in our knowledge and I would like your help in closing it.
I am not familiar with how a registrar who ignores part of the standard can be identified and corrected. Perhaps others may be able to answer this.
Once development which can be brought to Quality Management System is to rate the implementation effectiveness on a maturity scale. I would urge the community to upgrade the standard to include the maturity levels also to increase its implementation effectiveness.
