Porter (Five Competitive Forces) argues for "positioning" and "fit" to compete effectively; Collis and Montgomery (Competing on Resources) argue for "resource development and deployment" to effectively compete; and Kim and Maubourgne (Value Innovation: The Strategic Logic to High Growth) argue for an alternative "Value Innovation Logic" across five dimensions of strategy (industry assumptions; strategic focus; customers; assets and capabilities; and product and service offerings). It would seem that some of the elements of each article are at odds with the propositions made by others. Are they? How can we know which framework applies and when? Does one make more sense than the others? Discuss.
