There were few communication issues with alice, bob, betty, and frank for each communication issue where was the breakdown in communications: encoding, decoding, feedback, and so on

During communication between Herb and each of his teammates, there was some type of "blank space". Herb was not communicating properly as a project manager should. His staff either did not understood what he was trying to say, missing information in his message, or did not communicated at all.

Alice - Encoding

Bob - Improper format for the message

Betty - Feedback

Frank - Decoding / Encoding
