Several large computer-based R&D planning models, developed over the past few years, are examined to determine why such models have not been adopted for full and regular use by R&D managers. The models consider, in various degrees, three major tasks of the R&D planning process: (1) identifying and ranking organizational objectives (such as desired operational capabilities), (2) evaluating candidate R&D projects based on their contribution toward achieving the objectives, and (3) selecting preferred projects and allocating resources among them. Four models were selected for detailed analysis: TORQUE, RDE, PATTERN, and QUEST. None of these R&D planning models is currently in use, although several were tested and used for a short time, because of limitations in their methodologies, organizational constraints, and the attitudes and needs of R&D decisionmakers. It is concluded from a detailed examination of their methodologies that the models will not yield valid, reliable, and meaningful results.
