Polite Conversation to Skillful Discussion is part of the dialogue model created by Senge and Isaacs (1994). A team's communication process has levels. The process is adapted from the shared meaning model of communication, which includes a sender and a receiver. The model is a stage model on a continuum: Raw Debate -------- Polite Conversation --------- Skilful Conversation ----------- Dialogue You can pass through one stage or go back to an earlier stage.
