The document provides two models for constructively providing feedback: 1. The CARE formula for structuring feedback messages, which includes the Context, Action, Result, and Esteem of the situation, as well as exploring how to improve for the future when giving development feedback. 2. The REM model for handling others' anger, which includes reflectively listening without judgment, expressing empathy to acknowledge feelings, and then moving the discussion on to constructive issues and positive planning for the future. The models provide guidance on structuring feedback messages, addressing emotional reactions, and focusing discussions on solutions rather than past problems.
