This paper presents a research on the relationship between CIO performance and the CIO skills and CIO job demands. The CIO´s literature has many researches about the desirable or expected CIO skills, and few papers about the influence of organizational characteristics on CIO profile. The main contribution of this paper is to analyse the moderator effect of CIO job demands on the relationship between CIO skills and CIO performance. In order to describe this moderator effect, three hypothesis about the dimensions of three concepts are presented. A survey will collect the CIO perceptions about these three concepts. The collected data should be analysed by structural equation modelling.
