Coaching works great for change. Coaching is asking the right questions. It is not about providing answers. Every time you provide an answer to a person or team you take away an opportunity for them to self-organize, grow and learn. You take away an opportunity for them to take ownership of the change and get engaged. In the role of the coach your task is to create awareness and responsibility. Your goal is to help them discover what needs to change, how to change it and to help them actually implement the change.
