30 years ago when ISO 9001 was just a few years old and the concept of accreditation of management system certification bodies was still in the very early stages, third party certification of quality systems against recognized standards was envisioned as a path to significantly reduce customer audits and improve confidence in the supply chains.
As I have been voicing (now for 20+ years) the commoditization of audits and certificates has meant many stakeholders don’t equate certification with increased confidence and decide to maintain or revert to extensive system audits of their direct suppliers. We should also remember that supplier audits vary tremendously in scope. Many second party auditors focus on process audits, not system audits. Against that there is very little recourse from the suppliers side.
We have a 2nd party audit process, but has triggers to initiate. If a supplier is 3rd party certified and are meeting quality and delivery performance targets, what value is there for me to go audit them? With great performance, their processes are most likely pretty effective. It would be taking time away from myself or audit team to go verify processes that are already supposedly varied by a 3rd party auditor. That just costs time and money.
I do agree with you, a certificate doesn't mean a great product is produced. That being the cause, I go back to my original question. What then is the value add by getting this certificate? If it doesn't build supplier confidence or prove a system capable of making and delivering a good product, what's the point? Just a box to check off as part of the supplier selection process?
With costs of certification continuing to rise, the ROI should as well. Would you keep any other service provider if their costs continued to rise, and the added value did not?
