About this issue

THE THREE technical papers in this issue all deal with the perennial problem of evaluation in RD&E. Regular readers of this TRANSACTIONS will have found this to be a major theme in the published papers. One discouraging aspect of research and experimentation in this field of evaluation, such as that reported by Glass, Goodwin, and Moskowitz, is that it is not very cumulative. That is, “R&D” on the management of R&D or “Research on Research” is still in a state where individual studies are, in a sense, dropped in the pot to cook for a few years and do not necessarily form a monotonically increasing body of knowledge that managers can readily draw on for policy making, and practice.
