I understand the company vying for IATF 16949 certification need to show competence on the 5 core quality tools. Does it mean that the trainer of these tools should be certified to any IATF body offering the training?
Or can a well experienced quality professional do the training making sure the company staff are competent to these 5 core tools. I see no clause in requiring the trainer's qualification in the 16948 standard hence I believe it is OK not to be trained from a trainer from any IATF body.
If there is no special customer request or expectation in this regard, you can use your own employees who have been trained in 5 core tools before and has experience can provide internal training. It does not necessarily have to be issued by the person appointed by the IATF or by the certification body.
The important thing is that the trainer can demonstrate these competencies by having received training from a person or organization before and having sufficient experience on the subject in his CV.
