On Measuring the Contribution of OR

Cost-benefit analysis offers a common-sense approach to measuring the contribution of OR but encounters difficulties which have been recognized by Ackoff. Ackoff's concept of adaptivity appears to offer a neat solution to those difficulties but can be seen to provide only a methodology and to lack a background theory. The authors argue that: in general the development of background theory should precede the development of a methodology; for OR the background theory required is one of decision-making; and that the social sciences provide the resource from which an adequate theory of decision-making can be developed.
