Query: Early Warning

Thanks to the authors of this book. Organizations can be thought as social systems and We can not propose the mechanical solutions to the problems of organizations as social systems. The problems of organizations can not be solved quckly because of that all variables are not under control of managers and especially "management consultants". Hammer and Champy think of organizations like machines. I think this conviction completely wrong. The authors of this book focus the attention on the difficulties of the re-engineering process as a radical change method and stress the human side of the organizations. Re-engineering is a good method if it is used properly. Thanks...
