Boss/supervisor means the leader of group of people and boss/supervisor's important rule is to lead members of the group to do job efficiently.  The following qualities I mentioned in this essay are very crucial for boss to lead subordinates. 

 

  The ability to judge things reasonably is essential quality of boss.  Boss have to make important decision about the whole projects of the groups such as a department of a company.  When subordinates make drafts of new job or the company is involved in the problem, they are forced to decide the whole direction of the company or give subordinates adequate advice for the job, based on their experience, foresight, and analysis of each factors connecting the job or trouble.  Bosses' right of decision making is so potential that without their adequate individual ability as decision maker the group cannot go the right way.  Therefore, I think the ability of judge things right is very important. 

 

  Competent boss/supervisor knows his/her subordinates enough to allot jobs properly depending on their abilities, characteristics, and preference.  In my country, Japan, workers often colaborate with other colleagues and each worker has each familiar parts of jobs and each idea about the preferable way of doing job. The difference of workers' idea about the way of doing job might cause conflicts. Boss, who have right to order each workers to do jobs, have to prepare jobs considering each workers' traits in order to enhance the quality of each jobs.  Without each workers' personal information, boss cannot give adequate job for each workers.  Although subordenates have to make great effort to improve their flows in business and private things, doing their favorite and familiar things will yield the best result. 

 

 Boss/supervisor has decisive right to make the whole way of the group.  To make the good result as the whole, he/she is asked for their ability to judge everything adequately and to be familiar with their coworkers' characteristics of their ability, personality, and preference and idea for making good coordination of collaboration.
