The management of a system has to deal with the generation of the plans for the system, i.e., consideration of all of the things we have discussed, t… - C. West Churchman

In general, we can say that the larger the system becomes, the more the parts interact, the more difficult it is to understand environmental constraints, the more obscure becomes the problem of what resources should be made available, and deepest of all, the more difficult becomes the problem of the legitimate values of the system.

The scientist has to have a way of thinking about the environment of a system that is richer and more subtle than a mere looking at for boundaries. He does this by noting that, when we say that something lies ‘outside’ the system, we mean that system can do relatively little about its characteristics or its behavior. Environment, in effect, makes up the things and people that are ‘fixed’ or ‘given’, from the system’s point of view.

We have overwhelming evidence that available information plus analysis does not lead to knowledge. The management science team can properly analyse a situation and present recommendations to the manager, but no change occurs. The situation is so familiar to those of us who try to practice management science that I hardly need to describe the cases.
