Choosing an appropriate communication channel is vital for effective communication as each communication channel has different strengths and weaknesses. For example, broadcasting news of an upcoming event via a written letter might convey the message clearly to one or two individuals but will not be a time or cost effective way to broadcast the message to a large number of people. On the other hand, conveying complex, technical information is better done via a printed document than via a spoken message since the receiver is able to assimilate the information at their own pace and revisit items that they do not fully understand. Written communication is also useful as a way of recording what has been said, for example taking minutes in a meeting.
