I venture to disagree that 'minimize' has the same meaning as 'reduce' in this context.
As for the Management Rep - ISO 10018 WD3 (Second Draft)
has the following recommendations:
"-Top Management are ultimately responsible for the effectiveness of the quality management system.
-There should be guidance on competence criteria for a management representative and their responsibilities should be added to the job description with a % figure for time commitment.
-The responsibility as management representative should not be delegated to a junior level in the organization. (check new standard)
-In larger organisations, there should be a quality representative in each dept forming a cross functional team"
If you wish to contribute to developing the standard, you can contact the representative on TC176 from your country and they will advise you from there.
