As new information technology (NIT) has become a critical instrument for an organization to gain its competitive edge, the issue of how best to exploit and adopt NIT is now a pressing challenge for organizations and researchers alike. Based on upper echelon theory and individual differences literatures, this research paper endeavors to address the issue concerning the knowledge gap present in previous literature: the correlation between a top manager¡¦s personal traits and his NIT championing behavior. To bridge this gap, this paper attempts to explore to what extent a top manager¡¦s personality, ability, and belief characteristics can affect NIT championing behavior. We venture to propose in this paper a comprehensive model in which top managers¡¦ individual characteristics are integrated to facilitate the analysis of NIT adoption in organization. To test research model, Partial Least Squares (PLS) is used to verify the feasibility of the model proposed. Survey results from 130 top managers in Taiwan strongly support our proposition that a top manager¡¦s personality, ability, and belief have significant influence on NIT championing behavior. At the conclusion section of this paper academic and practical implication is discussed.
