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.

Successful problem solving requires finding the right solution to the right problem. We fail more often because we solve the wrong problem than because we get the wrong solution to the right problem.

Systems science and technology constitute one aspect of systems thinking, but the humanities and arts make up the other. The fact that design plays such a large part in the systemic treatment of problems makes it apparent that art has a major role in it as well. Ethics and aesthetics are integral aspects of evaluating systems... the systems approach involves the pursuit of truth (science) and its effective use (technology), plenty (economics), the good (ethics and morality), and beauty and fun (aesthetics). To compare systems methodology with that of any of the so-called ‘hard’ disciplines—for example, physics—is to misunderstand the nature of systems. The worry is not that the systems approach is not scientific in the sense which physics or chemistry or biology is, but that some try to make it scientific in that sense. To the extent they succeed, they destroy it.
