"Knowledge for Action is must reading for academics and executives alike. Chris Argyris once again demonstrates that he is the leading scholar in helping us understand why individuals and organizations are unable to learn from their actions and what steps must be taken to develop this essential capability. No executive who desires his organization to improve and learn continuously, or academic who wants to develop usable as opposed to merely useful theory, can do so without understanding the message of this book." (Michael Beer, professor of business administration, Harvard Business School)
