Being fair, calm, logical, sensitive, intelligent, analytical, tenacious, respectful, trustworthy, courageous, open-minded and sigle-minded

Those are the characteristics needed for a good Quality Auditor 

All of these characteristics are some of the LEADER's

The preference is for the discretion of the boss and let he allot me any task.

i beleive our aim as a leaders is to make our team in line with listed characteristics-

for me it is a face of ideal employee but people do not born ideal employees

so first the leader must value and try  have all above as much as possible to be a role model, but also it is leaders job to make all above collective characteristic of his team-no person can be ideal in all above-but team can

so my opinion is that leader together with team represent this hypotetical ideal employee real life model for the company and having more good team properly leaded is guarantee of successful business

Best qualities for any job

Leader 

In my personal opinion, one could be open to training and man management.

With good communication make a good leadership character.

All above are best leadership qualities. Would play a role of manager or leader of the team.
