Based on the Cervero and Wilson's perspective of program planning as social negotiation, the purpose of this study was to examine (1) how program planners negotiate planning participants' interests in the context of political power relationship in order to construct an adult educational program and (2) how the negotiations of interests affect the final products of the program development. Particularly, this study was a meaningful research attempt in that the case study was conducted in the corporate context of Korea with high level of power distance in organizational structure. As Cervero and Wilson indicate in their previous case studies, the research findings shows that (1) planners and planning participants always engaged in two types of negotiations in planning an adult education program: substantive negotiations about educational needs such as purpose, content, format, and administration plan and meta-negotiations about the power relationship related to their political and economical needs and (2) the meta-negotiations affected the outcomes of the substantive negotiations to decide the features of developed programs such as purpose, content, format, and administration plan.
