抄録

<p>In 1981, Sony announced the “Compact Disc” with co-development partner Philips. In the former studies, the strategic process of the CD was described as the great achievement of Norio Ohga (Sony's vice-president at the time), who seemed to have been the leader taking the initiative with the development of this product. However, in some publications written by certain engineers who actually developed Sony's digital recording technology, it is claimed that they had actually led the strategic process.</p><p>According to the analysis of various engineers' interviews, articles of audio industry magazines, and such engineer's publications, this paper found that the main strategic leader of this process was Heitaro Nakajima, who provided the motivation for this project as middle manager.</p><p>In fact, the very first digital recording equipment for consumer use (PCM-1) was gradually developed, promoted and approved by Heitaro Nakajima and his Sony Audio Technology Center (Sony Giken). Besides, from 1978, Sony Giken started technical sales and negotiations for approval of their digital recording format as a world standard by AES (Audio Engineering Society), which is the largest audio society in the USA. Through these activities, Sony Giken's engineers also identified new needs for a total digital editing support system. As a result, these activities prepared Sony's technological competence, which was especially welcomed by Philips.</p><p>Notably, these activities were not led by top management, but by the middle management. When engineers in enterprises plan to develop new technology using the company's resources, it is required that they provide proof of its legitimacy. The actors in this case study were also required to do this over and over, and they made great efforts to find the best answer each time. They do not only handle solutions of their engineering problems, but also actually seek proper proof of the legitimacy of their technology in various ways, among others they also have to persuade top managers, promote their technology overseas, and so forth. Taking these factors into consideration, it can be concluded that this strategic process is a process led by engineers.</p>
