This paper develops a typology of information cultures by synthesizing empirical and theoretical research in organization science and information science. Four information culture types are proposed. In a Result-oriented culture, the goal of information management is to enable the organization to compete and succeed in its market or sector. In a Rule-following culture, information is managed to control internal operations, and to reinforce rules and policies. In a Relationship-based culture, information is managed to encourage communication, participation, and a sense of identity. In a Risk-taking culture, information is managed to encourage innovation, creativity, and the exploration of new ideas. We expect most organizations to display to varying degrees norms and behaviors from all four types, and that the information culture profile of an organization would be related to its effectiveness. The paper ends by looking at the practical and theoretical value of a systematic examination of information culture and its link to organizational effectiveness.
