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

In the last two decades we have witnessed the emergence of the "system" as a key concept in scientific research. Systems, of course, have been studied for centuries, but something new has been added... The tendency to study systems as an entity rather than as a conglomeration of parts is consistent with the tendency in contemporary science no longer to isolate phenomena in narrowly confined contexts, but rather to open interactions for examination and to examine larger and larger slices of nature. Under the banner of systems research (and its many synonyms) we have also witnessed a convergence of many more specialized contemporary scientific developments... These research pursuits and many others are being interwoven into a cooperative research effort involving an ever-widening spectrum of scientific and engineering disciplines. We are participating in what is probably the most comprehensive effort to attain a synthesis of scientific knowledge yet made.

In proactive problem solving we specify where we want to go, and we try to get there. Although such an approach does not eliminate the possibility of overlooking relevant consequences of our solutions, it reduces the probability of doing so. The more ultimate the desired outcome we specify, the more likely we are to consider the intermediate and long-run consequences of our immediate actions. The more immediate the source of dissatisfaction we try to get rid of, the less likely we are to take account of relevant consequences. Therefore, the chances of overlooking relevant consequences are minimized when we formulate a problem in terms of approaching one or more ideals.

[Mistake 2:] Managers need all the information they want. Most MIS designers "determine" what information is needed by asking managers what information they would like to have. This is based on the assumption that managers know what information they need and want.
