This book is about the way people actually behave in business organizations. It is addressed to those who intend to assume positions of leadership in business organizations in or staff, at top, bottom, or middle levels of management - all practitioners of the art and science of business management. The book is concerned with helping these people improve their own personal competence in understanding and dealing with the many human problems that arise in complex organizations. All the material in this book was selected to help develop faith that there is order in the human universe; that man's behavior is not a chaotic chance affair; that, within limits, it is predictable; that intelligence can usefully supplement intuition in the conduct of important human affairs; and that knowledge and skillful diagnosis of human behavior can help liberate us from slavish conformity and from narrow moralistic judgements, and can help us to become more realistic, more understanding, and in the deepest sense of the word, more productive.
