Answer:
Lack of feedback
Explanation:
Lack of feedback: The term lack of feedback is defined as a process in which a speaker fails to modify or alter a particular message which is intended to help the listener in a better way to understand the speaker's position and attitude. If any business fails to develop an open feedback process then they are being operated in a communication vacuum.
Feedback is considered as necessary as it provides a positive criticism and allows to change things wherever required.
