Description of the characteristics and mechanics of the Delphi technique of identifying the likelihood of occurrence of specified future events precedes suggested uses for the technique in research, planning, and teaching. The procedure involves obtaining individual predictions, aggregating results, presenting results to the individuals, and having individuals evaluate predictions. A RAND Corporation study to predict major developments in population growth, probability and prevention of war, future weapon systems, automation, space progress and scientific breakthrough illustrates the mechanics of the technique. The potential of the procedure for resource forecasting, application of the technique to establish city planning goals, and a discussion of a modified version of the procedure as used in teaching a graduate course in research methodology indicate the possible value of the Delphi technique in incorporating variables in research and in attempting to identify priorities at various spatial scales of planning.
