I am working as Quality Assurance manager. We are a ISO 9001: 2008 certified organization. We are hoping to upgrade to ISO 9001: 2015 version by the end of this year. Related to this I have some queries:
1) List of trainings which QA staff must undergo for successful transition
The QA staff doesn't have to undergo any training, they only need to get familiar with the standard. It can be done by attending some external training or conducting in-house training. Here you can find free ISO 9001:2015 Foundation online course https://training.advisera.com/course/iso-9001-foundations-course/ that can help your staff achieve the competence.
2) Can these trainings be self-study or must be certified training sessions?
There is no requirement defining the type of training, so you can choose any option that works best for you.
3) Once certified as internal auditor for ISO 9001: 2008, do the internal auditors still be trained for Internal auditor training ISO 9001: 2015.
