The purpose of this quantitative comparative methods research was to compare the perceptions relative to 12 Master of Business Administration (MBA) skill sets of respondents situated in non-member countries of the Organisation for Economic Cooperation and Development (OECD) with the findings of a prior study of United States situated respondents. The findings suggest that general agreement of United States situated MBA program directors and non-OECD situated MBA program directors on the ratings of importance of the MBA skill sets. Non-OECD MBA program directors, however, tended to rate the effectiveness of MBA programs in developing the skill sets somewhat lower than United States based MBA program directors. The perception of corporate recruiters of MBAs for both importance of MBA skill sets and effectiveness showed consistency in nearly all of the 12 skill sets. An examination of the significance of differences among three subgroups of non-OECD respondents--MBA program administrators, recruiters, and MBA graduates--demonstrated a high level of consistency of ratings of importance of MBA skills sets and effectiveness of MBA programs. A further analysis using an importance-effectiveness methodology identified patterns of differences in perceived needs for improvement among the non-OECD MBA program administrators, recruiters, and graduates. Recommendations are made for further study including an examination of models for MBA skill sets definition to include additional dimensions or domains explicitly focused on contextual elements, such geographic differences in business practices and cultural elements.
