In any management system audit, including an audit against ISO 17025, the external auditor will try to ascertain if the person is competent for the function at hand. As in any organization, sometimes, one needs to rely on assistance from colleagues and co-workers in order to accomplish something. So, it should NOT be a concern to the external auditor if the technician seeks assistance from someone on how to get something done. However, it would concern me if EVERYTHING the technician does has to have assistance from other folks, as that would demonstrate s/he is not competent for the functions at hand.
An audit is not a closed book test; it is an assessment of the system in place.
