There are always barriers of communication between parts of the business which mean that messages do not get through or that the receiver of the information may not understand it. There can be a number of barriers to communication:
If a business has offices in different areas it can be difficult for meetings to take place. This could result in poor co-operation between parts of the business, which may lead to a loss of efficiency and profit.
A multinational business might find that its offices in different parts of the world use different languages. This will inevitably increase the difficulty of communication between them.
As a business grows, it tends to introduce more layers of management. This can make communication harder as messages from the top of the organisation to the bottom have to go through more people. Decision making is slowed down and there may also be a greater chance that any message will get distorted, which could ultimately cost the business money.
The ability of the sender to explain a message and the receiver to understand it are important. If an order must be sent out by a certain date, but the sender simply asks for as soon as possible, the communication would not have been effective.
Jargon is a word or phrase with a specialised or technical meaning. Certain terms understood by a particular group of people may be meaningless to another group which may lead to messages not getting through or being misunderstood.
