This book explains many of the principles of General Management. I have a deep standing commitment to excellence in teaching general management skills and this dedication is quite evident in this book. Today, as in the past, successful businesses depend on visionary leaders and real general managers. Every successful CEO realizes intuitively that business and management is part science and part art. However, rarely do Management books make this case. The general manager has a predicament unlike any other. This person is subject to immense pressure from others, must have a bias for action, and yet must analyze carefully and comprehensively, often under conditions of incomplete information. General managers do not solve problems; they manage messes. Russell Ackoff, professor at the Wharton School, wrote, ¿Managers are not confronted with problems that are independent of each other, but with dynamic situations that consist of complex systems of changing problems that interact with each other. I call such situations messes... Managers do not solve problems: they manage messes." The book is talking about General Management, Organization Design and Structure, Human Resource Management.
