Here there is the summary of the book that helps to get the coaching questions for managers.
What I Like of this video on coaching:
Lesson 1: Your advice is not as good as you think it is
Lesson 2: Spend Less Time telling what to do and more time asking good questions
4 Coaching Questions:
Q1 – What is on your mind?
Q2 – What else?
Q3 – What is the real challenge here for you?
Q4 – If you are saying YES to this, what are saying NO to?
Conclusions
Less to time to say what to do.
More time to ask good questions.
