Abstract :
THE five technical articles in this issue all relate to one general theme in the management of R, D, & E — problems of measurement for use in decisionmaking, evaluation, and control. Three of these five papers were written by people currently working in industrial or government organizations, and a fourth was written as the result of a summer visiting program in a government organization (NASA). These papers, and the work they represent, reflect management´s intense interest in obtaining valid measurements on which to base their decisions.
