回答： In program, we often discuss a issue or a topic by a meeting. We barely use text messaging or e-mail in our program when we want to listen to everyone's ideas or to make a brainstorm. For that we are a small team with about 50 people, we don't use telephone or voice-messaging either.

回答： Upsetting and controversial topics seems annoying for everyone and may cause a boring, competitive atmosphere which will hurt the team by making everyone distrust others, loosing passion or even bringing a long-term negative atmosphere. In our team, the leader is very autocratic and refused to listen to others which makes the upsetting discussion very awkward that no one expect him would say anything and almost everyone except him would be in a negative condition of working for a quite long time.

回答： Everyone would be in a bad mood, be easy to loose temper, be irrational thinking when they are talking about a upsetting problems. So I prefer using a way that every body don't have to be face to face which may decrease the probability of arguing. For instance, we usually indicate the problem in a talking software like MSN firstly and talking the problem officially after every one has a preparation of the upsetting situation.

回答： E-mail, texting or other ways of communication that can give users a time to think and perform their opinions without any emotional elements such as a high voice or speedy speaking. They give us a way to calm down and to think the problem in different aspects.

回答： When the problem is emergency or it is complex that can not be showed clearly through a text, we use phones. But I really doubt the suitability of discussing a upsetting or controversial problem.
