"We've had a hundred years of management science and management consultancy based on Newtonian physics and Taylorist principles. A lot of good things like process reengineering and quality management happened by applying machine metaphors to the firm. The trouble is that when you move on to trying to manage areas such as knowledge, learning and strategy you are moving into a completely different frame - a system which is inherently complex. At that point you have to completely rethink management methods." -- Dave Snowden
