The fundamental basis of a firm's long-run success is the
achievement and maintenance of a sustainable competitive advantage.
Indeed, understanding which resources and behaviors lead to
SCA is the fundamental issue in marketing strategy (Varadarajan &
Jayachandran, 1999). A competitive advantage can result either from
implementing a value-creating strategy not simultaneously being
employed by current or prospective competitors, or from superior
execution of the same strategy as that of the competitors (Bharadwaj
et al., 1993). Other firms’ inability to duplicate the benefits of this
strategy sustains the competitive advantage (Barney, 1991).
