I just finished The Coaching Habit, which outlines seven coaching questions to keep you developing the coached vs giving advice:

  1. What’s on your mind?
  2. And what else (it takes 3 times to get to the cause)?
  3. What’s the real challenge for you here? Instead of ask why questions, ask what questions.
  4. What do you want? Identify the root need from their answer.
  5. How can I help?
  6. If you’re saying yes to this, what are you saying no to?
  7. What was most useful to you? Helps you coach better.
