This study is a preliminary research aimed at developing a contingency model to examine the influence of organizational factors of culture, structure, and strategy on organizational performance. It is based on the responses of 91 managers from 63 companies in Sri Lanka. Research findings indicate that the relationships among members, speed of decision making, product strategies, creativity and innovativeness, quality of employees and technology, and strategic dynamism are significantly different among successful and unsuccessful organizations. Regression results showed that the return on investment was influenced by cultural, structural and strategic variables.
