Mushin Lee and Dohyeong Na present their analysis of data obtained from Korean project leaders in order to investigate the relationships between various factors and technical project success. When the radicalness of technical innovativeness is employed as a contingency variable, the result shows that existence of a champion is critical if the innovativeness is radical. Top management's support, R&D, production, and financial capabilities, and information acquisition during the development stage are related to the success, but there is no indication that the radicalness heavily affects the relationships. Information acquisition during the idea generation stage is not important for both radical and incremental improvement projects.
