Michael Porter
American economist (b. 1947), Harvard Business School professor whose
five forces,
value chain, and generic strategies frameworks dominated corporate strategy for three decades — the paradigm Kim and Mauborgne's value innovation empirically challenges.
Michael Porter is the most influential figure in the history of corporate strategy and the intellectual foil against which Kim and Mauborgne position their blue ocean framework. Porter's 1980 book Competitive Strategy established the analytical architecture that organized strategic thinking for a generation: the five forces model (rivalry, new entrants, substitutes, supplier power, buyer power) that determines industry profitability, and the three generic strategies (cost leadership, differentiation, focus) through which firms achieve competitive advantage. Porter's central thesis was that firms must choose: they can be special (differentiation) or cheap (cost leadership), but they cannot be both, because the activities required for each strategy are incompatible. Attempting to pursue both produces a 'stuck in the middle' position that earns below-average returns. The trade-off was presented as structural, grounded in the economics of production. Kim and Mauborgne's empirical research challenged this thesis directly, demonstrating that the most successful companies in their dataset pursued differentiation and low cost simultaneously through value innovation. Porter's framework remains
