Knowledge Management vs. IT. What is the Only Sustainable Source of Competitive Advantage Nowadays?

Few years ago, so many companies were convinced that they could reach positions of competitive advantage through investments in information technologies (IT's). This was certainly true for a while; however, IT's by themselves are not able to provide organizations with such a position anymore. One of the reasons for that is the tendency for the information technologies to become commodities; hence any competitor who has the enough acquisitive power could replicate the technological deployment of the leader, destroying this way the position of advantage. This work wants to explore a new source of competitive advantage called knowledge management, and its relationship with IT's. This paper also shows that companies should not regard IT's and KM as competitors but as coordinated efforts when trying to reach a position of competitive advantage.
