To achieve this feat, the organisation must first identify its competitive advantage within the industry. Once this is achieved, the firm can focus on trying to sustain their competitive advantage. A fundamental question that must be asked here however, is whether competitive advantage is sustainable.
“Sustainable competitive advantage” as a concept is rather vague. Much of the research surrounding the concept is debatable and open to various interpretations. (Coyne, 1986) maintains that “perhaps it is because the meaning of ‘sustainable competitive advantage’ is superficially self-evident that virtually no effort has been made to define it explicitly”. For an organisation, acquiring a competitive advantage is achievable but can competitive advantage be sustainable?

This view signifies his belief that to sustain a
