Do you think managers solve problems or manage messes?

According to systems theorist Russell Ackoff (1979):

Managers are not confronted with problems that are independent of each other, but with dynamic situations that consists of complex systems of changing problems that interact with each other. I call such situations messes…Managers do not solve problems, they manage messes. (p. 93)

Do you think managers solve problems or manage messes? Consider how thinking in systems alters or supports Ackoff’s hypothesis
