Since, the available informational and technological resources constitute a source of prosperity and differentiation for the organisations, the role of the Chief Information Officer (CIO) is becoming more crucial and vital. The thirty years of the CIO's existence have shown a path of changes and difficulties on defining and establishing the particular role within the organisational context. The present study examines the CIO role evolution over the last thirty years, analyses the CIO role at the present time and discusses the CIO role in the future. The examination of the evolution of the CIO role identifies four main areas of interest that are used as the conceptual framework of the study. These areas relate to business strategy, innovation and competitive advantage, relationships building and external environment. Based on a qualitative research approach, nine case studies of existing CIOs are conducted and analysed from the private and the public sector. The analysis provides insights about the responsibilities of the CIOs, currently, regarding each one of the role aspects and the furthermore, particular responsibilities for these aspects. The results of the analysis demonstrate that within the CIO role responsibilities there are activities such as active participation in the strategic planning, exploitation of information management as an enabler of innovation, active facilitation of consultation processes with the stakeholders and finally, networking with outside organisations such as suppliers and customers but also networking with peers to share best practices.Regarding the future of the CIO role, it is argued that the CIO role includes responsibilities relating to technology management and it is counterproductive to separate these responsibilities to another C-level executive such as a CTO. Finally, it is argued that the CIO role enhances the dynamic capabilities of the organisation by helping it to improve its learning processes and the way it transforms its information resources. The results of the study have implications to both industry and academia. The proposed CIO role model could be used by industry as a guideline for the job description of the role in question, as well as an evaluation scheme for the post holders. With respect to academia, the proposed role model could be used to identify the skills necessary for a CIO and thus, to help inform areas in which university educational programmes should focus on.
