Who are you communicating with and what message to they need to hear?
A communication strategy is a plan for communicating with your target audiences. It includes who you are talking to, why you are talking to them, how and when you will talk to them, what form of communication the content should take and what channels you should use to share it.
Communication professionals should be the ones responsible for communicating with external audiences. However, human ressources departments may also need to communicate internally about any changes that may effect employees.
