Reprinted with permission from Research Briefings Introduction The work of managers, of scientists, of engineers, of lawyers--the work that steers the course of society and its economic and governmental organizations--is largely work of making decisions and solving problems.

It is work of choosing issues that require attention, setting goals, finding or designing suitable courses of action, and evaluating and choosing among alternative actions.

The first three of these activities--fixing agendas, setting goals, and designing actions--are usually called problem solving; the last, evaluating and choosing, is usually called decision making. Nothing is more important for the well-being of society than that this work be performed effectively, that we address successfully the many problems requiring attention at the national level the budget and trade deficits, AIDS, national security, the mitigation of earthquake damageat the level of business organizations product improvement, efficiency of production, choice of investmentsand at the level of our individual lives choosing a career or a school, buying a house.

The abilities and skills that determine the quality of our decisions and problem solutions are stored not only in more than million human heads, but also in tools and machines, and especially today in those machines we call computers.

This fund of brains and its attendant machines form the basis of our American ingenuity, an ingenuity that has permitted U. There are no more promising or important targets for basic scientific research than understanding how human minds, with and without the help of computers, solve problems Cost information decision making make decisions effectively, and improving our problem-solving and decision-making capabilities.

In psychology, economics, mathematical statistics, operations research, political science, artificial intelligence, and cognitive science, major research gains have been made during the past half century in understanding problem solving and decision making.

The progress already achieved holds forth the promise of exciting new advances that will contribute substantially to our nation's capacity for dealing intelligently with the range of issues, large and small, that confront us. Much of our existing knowledge about decision making and problem solving, derived from this research, has already been put to use in a wide variety of applications, including procedures used to assess drug safety, inventory control methods for industry, the new expert systems that embody artificial intelligence techniques, procedures for modeling energy and environmental systems, and analyses of the stabilizing or destabilizing effects of alternative defense strategies.

Application of the new inventory control techniques, for example, has enabled American corporations to reduce their inventories by hundreds of millions of dollars since World War II without increasing Cost information decision making incidence of stockouts.

Some of the knowledge gained through the research describes the ways in which people actually go about making decisions and solving problems; some of it prescribes better methods, offering advice for the improvement of the process. Central to the body of prescriptive knowledge about decision making has been the theory of subjective expected utility SEUa sophisticated mathematical model of choice that lies at the foundation of most contemporary economics, theoretical statistics, and operations research.

SEU theory defines the conditions of perfect utility-maximizing rationality in a world of certainty or in a world in which the probability distributions of all relevant variables can be provided by the decision makers. In spirit, it might be compared with a theory of ideal gases or of frictionless bodies sliding down inclined planes in a vacuum.

SEU theory deals only with decision making; it has nothing to say about how to frame problems, set goals, or develop new alternatives. Prescriptive theories of choice such as SEU are complemented by empirical research that shows how people actually make decisions purchasing insurance, voting for political candidates, or investing in securitiesand research on the processes people use to solve problems designing switchgear or finding chemical reaction pathways.

This research demonstrates that people solve problems by selective, heuristic search through large problem spaces and large data bases, using means-ends analysis as a principal technique for guiding the search. The expert systems that are now being produced by research on artificial intelligence and applied to such tasks as interpreting oil-well drilling logs or making medical diagnoses are outgrowths of these research findings on human problem solving.

What chiefly distinguishes the empirical research on decision making and problem solving from the prescriptive approaches derived from SEU theory is the attention that the former gives to the limits on human rationality.

These limits are imposed by the complexity of the world in which we live, the incompleteness and inadequacy of human knowledge, the inconsistencies of individual preference and belief, the conflicts of value among people and groups of people, and the inadequacy of the computations we can carry out, even with the aid of the most powerful computers.

The real world of human decisions is not a world of ideal gases, frictionless planes, or vacuums. To bring it within the scope of human thinking powers, we must simplify our problem formulations drastically, even leaving out much or most of what is potentially relevant.

The descriptive theory of problem solving and decision making is centrally concerned with how people cut problems down to size: Out of this descriptive theory is emerging an augmented and amended prescriptive theory, one that takes account of the gaps and elements of unrealism in SEU theory by encompassing problem solving as well as choice and demanding only the kinds of knowledge, consistency, and computational power that are attainable in the real world.

The growing realization that coping with complexity is central to human decision making strongly influences the directions of research in this domain. Operations research and artificial intelligence are forging powerful new computational tools; at the same time, a new body of mathematical theory is evolving around the topic of computational complexity.

Economics, which has traditionally derived both its descriptive and prescriptive approaches from SEU theory, is now paying a great deal of attention to uncertainty and incomplete information; to so-called "agency theory," which takes account of the institutional framework within which decisions are made; and to game theory, which seeks to deal with interindividual and intergroup processes in which there is partial conflict of interest.

Economists and political scientists are also increasingly buttressing the empirical foundations of their field by studying individual choice behavior directly and by studying behavior in experimentally constructed markets and simulated political structures.

The following pages contain a fuller outline of current knowledge about decision making and problem solving and a brief review of current research directions in these fields as well as some of the principal research opportunities.

It gave for the first time a formally axiomatized statement of what it would mean for an agent to behave in a consistent, rational matter. It assumed that a decision maker possessed a utility function an ordering by preference among all the possible outcomes of choicethat all the alternatives among which choice could be made were known, and that the consequences of choosing each alternative could be ascertained or, in the version of the theory that treats of choice under uncertainty, it assumed that a subjective or objective probability distribution of consequences was associated with each alternative.

By admitting subjectively assigned probabilities, SEU theory opened the way to fusing subjective opinions with objective data, an approach that can also be used in man-machine decision-making systems.

In the probabilistic version of the theory, Bayes's rule prescribes how people should take account of new information and how they should respond to incomplete information.

The assumptions of SEU theory are very strong, permitting correspondingly strong inferences to be made from them. Although the assumptions cannot be satisfied even remotely for most complex situations in the real world, they may be satisfied approximately in some microcosms--problem situations that can be isolated from the world's complexity and dealt with independently.

For example, the manager of a commercial cattle-feeding operation might isolate the problem of finding the least expensive mix of feeds available in the market that would meet all the nutritional requirements of his cattle.

The computational tool of linear programming, which is a powerful method for maximizing goal achievement or minimizing costs while satisfying all kinds of side conditions in this case, the nutritional requirementscan provide the manager with an optimal feed mix--optimal within the limits of approximation of his model to real world conditions.

Linear programming and related operations research techniques are now used widely to make decisions whenever a situation that reasonably fits their assumptions can be carved out of its complex surround.

These techniques have been especially valuable aids to middle management in dealing with relatively well-structured decision problems.In economics and business decision-making, a sunk cost is a cost that has already been incurred and cannot be recovered (also known as retrospective cost)..
