The purpose of this study is to develop a Korean D&I program for corporate managers to improve awareness of Diversity and Inclusion (D&I) and to properly establish the organization s D&I. To achieve this research purpose, program development has been conducted by adopting an Interactive model that allows contextual factors based on flexibility. Through literature review, definition and dimensions of D&I in workplace and survey questionnaires was drawn. In addition, a total of 20 corporate managers (9 people) and HRD staff (11 people) working in Korea were selected and analyzed. Therefore, individual-level and organizational-level D&I demand priorities were measured through survey. Moreover, through 1:1 in-depth interview, the requirements of the Korean D&I program were identified as the main needs of open mind, self-awareness, uniqueness, belongingness, diversity awareness, strategic communication, coaching, leadership and trend. Based on these results, the Korean D&I program TRUST (Time to Open, Restructuring, Understanding D&I, Strategy D&I, Trace my leadership) was developed for corporate managers. Each module emphasizes the understanding of D&I concept and addresses the needs to break unconscious biases, thereby establishing strategies to enhance D&I and becoming an inclusive leader. Finally, limitations of the study and suggestions for subsequent research were suggested.
