Multinational firms are concerned mainly with the entry modes at the early stage of internationalization; on the other hand, they emphasize localization to operate successfully with the host government at the after-entry or operational stage. Especially, it is important for multinational firms to understand the host government's culture at this stage. In this article, we attempt to measure IC(individualism-collectivism) tendencies on the individual level. We measured an individual's IC tendencies in relation to eleven groups (family, close friends, immediate supervisor, colleagues, immediate subordinate, school senior, school junior, school friend, elder hometown friend, hometown friend, and younger hometown friend). As a results, target group collectivism shows as follows: family, close friend, colleague, immediate subordinate, school friend, immediate supervisor, school senior, school junior, elder hometown friend, hometown friend, and younger hometown friend. Among the various factors determining the level of organizational commitment and job satisfaction, job tenure, autonomy, feedback, distributive justice, department collectivism, and horizontal collectivism were found be significantly related to organizational commitment. On the other hand, age, variety, autonomy, distributive justice, department collectivism were found be significantly related to job satisfaction.
