How can one verify competency of internal auditors? I am a quality manager who has conducted audits for 28 years. What training do I need to take to be competent in auditing my company to IATF 16949 or conducting 2nd party audits? Do I have to take lead auditor class? I signed up for internal auditing class to IATF but do not know if that will be good enough to be considered competent. I am not confident in the IATF standard requirements.
In order to demonstrate competency, the internal auditors must demonstrate understanding of five points listed in the standard under the clause 7.2.3. The standard doesn't say how to verify the competence, so it can be done in any way that the organization finds the most appropriate, whether it is by attending internal auditor courses and providing certificates, or by conducting internal training and testing the auditors against the above mentioned criteria.
As far as the second-party audits are concerned, the standard also defines requirements for competency in clause 7.2.4, and again it does n't require certificate and neither it defines the method for verification of their competence, so the same rules apply.
Internal auditor course is a good way of demonstrating competence, simply because it provides documented evidence provided by the third party.
