A balance needs to be struck in communication between management and staff. Insufficient communication leaves staff 'in the dark' and is demotivating. Excessive communication leads to information overload, eg when staff find hundreds of messages arriving in their intray each day.
Communications fail when a message is unclear or the receiver does not understand technical jargon. Selecting the right medium is important. Messages may never be received if they are sent at the wrong time or to a junk email folder.
The result is inefficiency and higher costs, as more resources are needed to achieve the same result.
Training staff to select an appropriate medium and send clear, accurate, thorough messages will improve the quality of communications, especially if there is an opportunity for feedback.
