American philosopher and systems scientist (1913-2004)
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.
For the scientist a model is also a way in which the human though processes can be amplified. This method often takes the form of models that can be programmed into computers. At no point, however, the scientist intend to loose control of the situation because off the computer does some of his thinking for him. The scientist controls the basic assumptions and the computer only derives some of the more complicated implications.
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, the overall goals, the environment, the utilization of resources and the components. The management sets the component goals, allocates the resources, and controls the system performance.
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.
The idea of a ‘system approach’ is both quite popular and quite unpopular. It’s popular because it sounds good to say that the whole system is being considered, but it’s quite unpopular because it sounds either like a lot of nonsense or else downright dangerous – so much evil can be created under the guise of serving the whole.
It is only natural to expect that improvement can occur in certain sectors of the system without our having delved deeply into the characteristics of the whole system. Thus, for example, there is a tradition in Western thought that parts of the whole system can be studied and improved more or less in isolation from the rest of the system. So deeply ingrained is this concept of social improvement in Western thought that we naturally think it proper to subdivide our society into functional elements. We think it proper that each element develop its own criteria of improvement and that the elements be as free as possible from the interference of the other parts of the social structure... Men have neglected a very serious problem in defining improvement. The problem is very simple: How can we design improvement in large systems without understanding the whole system, and if we the answer is that we cannot, how is it possible to understand the whole system?
It is sheer nonsense to expect that any human being has yet been able to attain such insight into the problems of society that he can really identify the central problems and determine how they should be solved. The systems in which we live are far too complicated as yet for our intellectual powers and technology to understand.
