This document discusses coaching anti-patterns and techniques for effective coaching. It identifies "colluding" and "scrum policing" as anti-patterns where the coach remains silent about problems or enforces rules without empowering the team. The document advocates for direct, challenge-based coaching where the coach addresses issues directly, challenges limiting beliefs and status quo thinking, and empowers teams to solve their own problems through experimentation and learning from failures. Coaches are encouraged to reflect on when they have fallen into anti-patterns and use "repair bids" like questions or gestures to de-escalate negativity and get coaching back on track.
