OSITG01This study provides some empirical insight into managerial roles of chief information officer (CIO) based on Mintzberg's classic managerial role model and CSC's information systems (IS) leadership roles. A survey was conducted in Norway to investigate potential predictors of leadership roles. Statistical results indicate that CIOs find the role of entrepreneur most important, and this role has growing importance with increasing end-user computing maturity, IS management maturity, administrative effectiveness, number of persons reporting to the CIO, number of persons working in IS/IT and level of education. While end-user computing maturity has significant influence on the importance of the entrepreneur, spokesman, leader and liaison roles, IS management maturity has significant influence on the entrepreneur, change architect and technology strategist roles. Results obtained in this study in Norway differ from earlier results obtained in the US. Both constructs and survey instrument should be revised in future research.
