Abstract
In this paper, based on interviews for the foreign subsidiaries of Bosch in three Asian countries (Japan, South Korea and India), some actual situations of overseas business of Bosch are clarified. In Bosch, the establishment of global in-house standardization and the development of foreign subsidiaries' capability have been done under the strong leadership of the home country headquarters. As a result, paradoxically, some foreign subsidiaries of Bosch began to play a global R&D function or a Mother-Plant function, which were entirely conducted by the home country headquarters only in the past.
