A subject may be said to be in such a state if he (it) wants something and has unequally efficient alternative ways of trying to get it. - Russell L. Ackoff

Most managers have some conception of at least some of the types of decisions they must make. Their conceptions, however, are likely to be deficient in a very critical way, a way that follows from an important principle of scientific economy: The less we understand a phenomenon, the more variables we require to explain it.

Managers are not confronted with problems that are independent of each other, but with dynamic situations that consist of complex systems of changing problems that interact with each other. I call such situations messes. Problems are extracted from messes by analysis. Managers do not solve problems, they manage messes.

Doing philosophy was an opportunity to learn something new. I expected this to be an adjunct to my practice of architecture. But it turned out the other way. It turned out that the philosophy of science gave me the opportunity to design social systems, and I was more interested in people-oriented systems than in buildings. They were both design, but different kinds of design. I like creating things.
