A revised and updated version of the bestselling practical introductory book on coaching, which has been highly praised both inside and outside the industry! Due to recent changes in the business environment, the field of coaching is also experiencing the following waves of change. (1) An increase in executives who hire executive coaches (2) An increase in organizations that introduce coaching throughout their companies as a means of organizational development (3) A shift to evidence-based coaching (4) A shift in the basis of management to one-on-one interviews (5) An expansion from business to sports, medicine, administration, and education In response to these trends, while maintaining its position as an introductory book to learn about "effective coaching," the chapter on coaching cases has been revamped to introduce examples of companies that have introduced coaching in a multi-layered manner as a means of organizational development. You can learn about the intentions of professional coaches in advancing dialogue and the communication techniques they use based on actual dialogue examples. There are many books on coaching, but not many that combine comprehensiveness and practicality to this extent. This is a book that can be widely recommended as an introductory book for first-time learners and as a practical book that will be useful to professional coaches as well.
