It is difficult to develop objective evaluation techniques for the productivity in an R&D organization because there exists such as time lag between inputs and outputs, difficulties of measuring the influencing factors and results of a research and of comparing R&Ds with other objects towards innovation, and problems in identifying analysis elements. Particularly, governmental research institutes, pursuing publicity, have more difficulties in evaluating research achievement than the private ones. In evaluating the productivity of R&D organizations, this study aims at practically using the quantitative evaluation techniques by applying them to the public as well as private institutes. This will be finally contributing to decision making for effective management of R&D organization.
