edit: According to the Resource-Based View (RBV), IT capabilities are a valuable source of competitive advantage as they are rare, non-substitutable and cannot be easily replicated by competitors in comparison to IT resources (Zhang et al., 2009). However, some dimensions of IT capabilities may lose their distinctiveness over time and become standardized and available to most rivals and are not unique and reclassified as IT resources. In other words, they become necessary but not sufficient to create competitive advantages.
