There is another marketing issue with Porter’s matrix, the dichotomy between “industry wide” and “narrow target” strategies. An industry wide strategy, better known in the marketing literature as a mass market strategy (i.e. a single marketing mix for all customers in the market) is most relevant for large firms with strong financial resource offering a standardized commodity. Porter’s “narrow target segment,” commonly known in marketing as a “niche strategy” (targeting a narrowly defined customer segment with a tailored marketing mix), is often a necessity for a smaller firm with strong marketing skills but limited financial capability. However, Porter’s matrix does not recognize several alternative marketing strategies sandwiched between these two. In between a mass market and a niche strategy, there are a variety of segment expansion strategies (e.g. multi-segment or across-the-board, as previously discussed). Thus, all variations of Porter’s generic strategies, except cost leadership, may also be derived from Smith’s (1956) core marketing strategies: differentiation and segmentation.
