Final answer:
Good feedback is specific, constructive, and part of an interactive communication process, provided promptly and regularly. Authoritarian group leadership features top-down communication. In system feedback, positive feedback amplifies changes, whereas negative feedback aims to maintain balance.
Step-by-step explanation:
In an organizational context, characteristics of good feedback would include being specific and constructive rather than vague and ambiguous. Good feedback should be a two-way communication where both parties can discuss and understand the feedback provided. It is also important that feedback is given in a timely and frequent manner, rather than delayed and infrequent, so that the recipient can act on it and improve performance promptly.
Regarding the patterns of communication in different types of group leadership, an authoritarian leadership style would typically have a communication pattern that flows from the top down.
Feedback mechanism in systems can be identified as either positive or negative. Positive feedback mechanisms amplify changes, while negative feedback mechanisms counteract changes to maintain equilibrium. An example of negative feedback in biology is end product inhibition where the product of a reaction inhibits the enzyme that produced it to prevent overproduction.
