To effectively communicate in formal business meetings, one should prepare properly by deciding meeting details like time, place and date in advance, booking meeting space, developing an agenda and sending it out for approval. During the meeting, arrive early and come prepared, do not interrupt and refrain from electronics, speak in turn and keep questions brief while paying attention. Make the meeting interactive, keep matters confidential and ask for feedback before attending the entire meeting. Proper etiquette should also be followed after the meeting.
