He originally ranked each of the three dimensions (level of differentiation, relative product cost, and scope of target market) as either low, medium, or high, and juxtaposed them in a three dimensional matrix. That is, the category scheme was displayed as a 3 by 3 by 3 cube. But most of the 27 combinations were not viable.
Porter 's Generic Strategies
In his 1980 classic Competitive Strategy: Techniques for Analyzing Industries and Competitors, Porter simplifies the scheme by reducing it down to the three best strategies. They are cost leadership, differentiation, and market segmentation (or focus). Market segmentation is narrow in scope while both cost leadership and differentiation are relatively broad in market scope.
Empirical research on the profit impact of marketing strategy indicated that firms with a high market share were often quite profitable, but so were many firms with low market share. The least profitable firms were those with moderate market share. This was sometimes referred to as the hole in the middle problem. Porter’s explanation of this is that firms with high market share were successful because they pursued a cost leadership strategy and firms with low market share were successful because they used market
