(这是商务英语里面的一个问题,关于成功会谈)

1) For the interdepartmental communication to be effective,one department must send a clear and comprehensive message to another department,and the message must be clearly and completely understood.If it's not,there will be problems and it can lead to confusion,lack of morale and frustration among employees and departments.
2) It is important to ensure that all departments are on the same page as work situations change.One department may make a change that affects another department.If the first department doesn't communicate those changes to the other department,there can be confusion,frustration and anger.Therefore,it can end up in chaos,with a lack of motivation among employees and an absence of trust and respect between departments.
3) Oral communication can be carried out between departmental leaders via the phone,video conferencing and one-on-one meetings.This gives opportunities to have discussions and help to make decisions quickly.Any decisions or required actions made through the meetings should be followed by written documents,such as meeting minutes,memos or emails to ensure everyone who requires an action is going to follow up correctly.
