In this work, Antonio Montes Orozco, author of "Scrum for Non-Techies" and "The Work Stress Cycle", once again shows his amazing synthesis capacity to explain, in 100 pages, what a Scrum Master needs to know about Agile Coaching. This work contains multiple examples that make it an essential guide for any Scrum Master who wants to delve into the world of Coaching. It is also highly recommended for all those leaders who want to learn how to hold productive conversations.
