This study extended research on organization characteristics associated with successful technology-based competitive strategies in U.S. firms to Brussels-based firms in order to specifically investigate the multicultural aspects of competitive strategies in an international context. Organization characteristics associated with success in U.S. firms also were associated with success in Brussels firms. However, the pattern of performance criteria varied. Brussels firms with responsive and innovative organizational systems exhibited higher sales growth, higher creation and maintenance of employment, higher reduction of employee turnover and higher overall success. In contrast, firms characterized by traditional and hierarchical management philosophies exhibited lower profit growth, lower profit margins and lower returns to shareholders.
