Step-by-step explanation:
The basic model of interpersonal communication that managers need to know is the sender-receiver model. This model consists of a sender who encodes a message and sends it through a channel to a receiver, who then decodes the message. The sender and receiver can also exchange feedback to ensure understanding.
For example, if a manager wants to communicate a new project to their team, they would encode the message by preparing a presentation or email. They would then send the message through a channel, such as a team meeting or email distribution list. The team members would receive the message and decode it by listening or reading, and they can provide feedback or ask questions if needed.
