Answer:
Managing subordinates can be tricky. You will be dealing with personality and beliefs that differ from yours. The way I handle it is be becomes friends with them and carefully study how they are motivated. But you have to be careful not to over do it. Otherwise friendship becomes burdens rather than advantage. There are times or situation that you have to assert your authority. Make them feel that they are important in the group so you can get participation and cooperation. Do not use the word "You are wrong" in any discussion even they are. Find words that are appropriate which will not described their weaknesses. Most subordinates does not like being told bluntly especially in front of their colleague's. If you must, do it privately and show compassion and trust in them. Always appreciate what they do, give credit to them if they do something good. Avoid confrontation or argument; it doesn't help. You might win the argument, but the truth is you lost, because you created an enemy.
Also, one very good rule of thumb that works well is to treat subordinates as you want want them treating you. Put themselves in your shoes, and vice versa and image how you would want to be treated. This usually works very well.
