In general, feedback is the process whereby part of the output of a dynamic system is examined in order to modify and optimize features of the system itself. In the case of communication within an organization, feedback has the purpose of confirming, reinforcing or modifying the recipient’s attitude or behaviour in order to improve the overall quality of the communication and performance (at individual or organizational level). The types of communication feedback we will deal with in this e-learning course are: the panegyric; praise; destructive and constructive reprimands.
