In this study, we report the summary characteristics of CEOs of SI firms in Korea. In the first part of our paper, age, educational background, and career of CEOs in SI firms are analyzed according to CEO types (owners versus professional managers). In the second part, CEO tenures of Si firms in Korea are compared with those in the U.S. and Japan. We found that CEO tenures of SI firms in Korea are remarkably shorter than those in the U.S. and Japan. In conclusion, we contend that CEO systems in Korean firms should be improved to guarantee the longer tenures especially for professional managers.
