Although, the resource based theory mentions both resources and capabilities to be sources of competitive advantage, not much distinction between the two has been made in research on competitive advantage. Therefore, this proposal presents a literature review of the research on information technology (IT) and organizational capability, and then puts forth a model of IT capability as a moderator in the relationship between IT resources (as indicated by the IT investment announcements) and competitive advantage (as indicated by the firm’s stock performance).
