This paper aims to present a prospective trend to establish a proper CALS conception and an efficient CALS environment in Korea.. It is crucial at this point for Korea to develop a comprehensive CALS conception which considers our present economic and social situation, national security, and our national emotion. Korean CALS has been developed and led mainly by the government and private industry. It is now necessary to improve CALS conception in Korea by making CALS standard more interchangeable among international as well as domestic business fields through EDI and the automation of the industries along with the government. In this regard, this paper proposes three potential methods to accomplish this goal and discuss each of them in detail. First, we suggest to establish a proper CALS introduction policy on the government level. We propose an introduction policy with three phases such as introduction, spreading and target which will cover through the year 1996 to 2007. Second. we suggest to establish a proper CALS standardization policy by improving the acquisition of digital data and process, and modernizing infrastructure. Third, we suggest that the government should amend and enforce the necessary laws and acts for more efficient CALS implementation in Korea. Government should arrange for these acts to be applied not optionally but obligatorily to Korean enterprises so that they survive the harsh and competitive world market in the upcoming 21th century.
