What are different between formal meeting and informal meeting?

Answer 1

A formal meeting is a preplanned meeting. It has a predetermined set of topics that one wishes to discuss along with a set of objectives that one wishes to achieve at the end of the meeting. At a formal meeting, generally it is a senior executive who presides over the affair. The members of the meeting are often given a considerable period of notice before the meeting, preferably through formal means such as memos. As the title suggest, the atmosphere in such meetings is generally somber, formal.

Informal meetings are generally not planned well in advance. The members are not notified through formal means. They generally take place in neutral surroundings, for example in a restaurant rather than a boardroom.
