The basics of management remain the same. Managing is very different in different jobs, organizations and countries. Management is changing radically. All three statements are true. Most books on management focus on the first or the third statement. This book is unusual in that it takes account of all three. It does so because effective managers increasingly have to understand not only the basics of management, but also how it is changing and how that affects their work and careers. Managers are much more mobile than they used to be, so they also have a greater need than in the past to understand where, how and why management differs.
