I am in a start-up company and we've established a management system. All the documents are there. In my experience with ISO 9001, exact job title of personnel is required when putting the 'responsible person for the task' (except for AdHoc-type activities). However, since this is a start-up, the personnel doing the same function change job title from time-to-time. Another problem is when there are new hires with new job title entering the organization. We're only less than two years in business and my documents are already in revision 2 or 3. Do I really have to change every time a person changes job title or there is new hire?
