Abstract
Research and technology development are different from each other in the evaluation. It should be thought that technology development begins with the theme selection concerned and its completion is evaluated by the commercialization of the performance got through the development or by the possibility of the performance to the key technology.
Economic analysis is required when the development project moves from one phase to the next one. The analysis gives us useful informations such as R & D efficiency, return on investiment (ROI) and product cost performance in comparison with conventional processes.
