Hi..
More than the author of all documentation, the requirement to know about any QMS is the PDCA approach and the interactions of the processes. Add to this the 8 principles of quality management ...
- 1 Customer focus. ...
- 2 Leadership. ...
- 3 Involvement of people. ...
- 4 Process approach. ...
- 5 System approach to management. ...
- 6 Continuous improvement. ...
- 7 Factual approach to decision making. ...
- 8 Mutually beneficial supplier relationships.
Now add to this the specific requirements of the medical device you are getting involved into, as compared to the definitions given in the ISO 13485 as well as specifics mentioned within the standard ISO 13485. This will help in understanding the exclusions and non-applicability.
There are several open training materials on the web (A good web search will get you plenty) as well as Training programs about ISO 13485 introduction are available (again a web search for such training resources)
After being exposed to these, documenting the training is a no big deal, when competency can be demonstrated. You really don't need any certificate to showcase it, but if he gets one it will add.
