All in all, with the recognition of the value chain's claimed benefits and potential weakness stated above as well as some implementation issues, if the organizations can properly adopted the value chain theory, it may assist organizations to explore the role and contribution of its resources which would maintain sustainable competitive advantage in the long run.
