One of the great blunders of modern mgmt was to break up chains of command. This was done with the idea that each section/department would do it's very best and so you would improve customer service and reduce monolitical hierarcies. Of course, quiet the opposite has happened! I won't bore you with why and how I think that has occurred - in my view it has.
except that I would say, "one of the
MANY great blunders of modern management".
