excluded from the domain of "nonquantifiable aspects" of management." Proper to management science is the creation of methods general enough to apply to the ill-structured problems of management-taking them on their own terms and dealing with them in all their vagueness—and not demanding more in the way of data than the situations provide. To be sure, these methods will also be weak but not necessarily weaker than is inherent in the ill-structuring of the task.
That management science should deal with the full range of management problems is by no means a new conclusion. In this respect these two hypotheses only reinforce some existing strands of research and application. They do, however, put special emphasis on the extent to which the hard mathematical core of management science should be involved in ill-structured problems. They say such involvement is possible.

One need only note the extensive calls to arms issued to the industrial operations researcher to consider the total decision context, and not merely that which he can quantify and put into his model, to realize the firm grip of this image.
