Just because you communicate a new policy, don't assume that it will be understood the way you intended. There are many barriers to effective communications, some of which include:

• Language used - is it common to the recipient (not only is it English, Chinese, French, etc.) but is it technically on the same wave-length as the recipient? Do they understand the jargon? 
• Attention - is the communication going to capture the attention of the receiver? If you are sending a message about a new policy in the middle of the busy season, or when the production line collapsed, or you are in the middle of a major industrial dispute; then how much attention can you reasonably expect receivers to give?
• Relevance - why should they pay attention? If it's not relevant to the receiver, then why should they bother? 
• Right and left brain - some people prefer detail while others are very comfortable in the abstract. If the communication isn't pitched correctly, it will either 'bore them' or 'lose them'.

History

 

Learn from your communications history. What has worked well in the organisation during past changes and what hasn't?

Although past methods may need to be modified for the new context, don't commit the same errors that occurred before.

Change agents, Champions and policy advocates

 

Sometimes people don't like to be told. Those types of people and some types of communications can often be more effectively delivered through change agents, champions and policy advocates.

Quality

 

When you communicate, regardless of the format (verbal, visual, etc.) ensure that it is technically correct. Poorly delivered communications undermine a policy's legitimacy and draws attention to managers' capability. "If they can't get the spelling right, then what chance have they got of implementing this difficult policy that requires an acute eye for detail?"

Consistency

 

There is nothing worse than getting two communications with different details.

To avoid this occurring, ensure that all formal communications are channelled through one person or one group of people to ensure consistency and accuracy.

A robust review and approval process is almost always warranted.
