With due respect to your experience in the field, I slightly disagree with your comment. Why is the MR (Management Representative) solely responsible for auditing? For any organization to obtain IMS (Integrated Management System), a lot of work is required. It is a collective effort of all the departments within the organization, leading to a successful audit and helping in obtaining certification. The MR alone cannot maintain all the documents needed for certification.
When it comes to our organization, competency development through training is the responsibility of HRD (Human Resource Development). They must keep all the relevant documents required under clause 4.4.2 Competence, Training, and Awareness of ISO 14001-2004.
