Two dimensions, three strategies
Porter combined the source of advantage (low cost or uniqueness) with competitive scope (broad or narrow) to define generic strategies.
- Cost leadership: the lowest cost in the industry through scale, learning, efficient processes and input access, as at Dell with direct build-to-order sales, or Walmart.
- Differentiation: unique value through quality, design, brand, service or technology that earns a price premium, as at Apple.
- Focus: serving a particular segment, region or product line with either cost focus or differentiation focus.
Risks
Cost advantages can be eroded by technology change or imitation; differentiation fails if the premium grows too large; focus strategies suffer when segments shrink or broad competitors move in.
Stuck in the middle
Porter warned that firms pursuing both without achieving either earn low returns, because cost cutting and differentiation require different investments and cultures.
Critiques
Firms such as Toyota and IKEA combine low cost with differentiation, supporting hybrid strategies, and Kim and Mauborgne's Blue Ocean Strategy (2005) argues value innovation can pursue both. Porter's framework nonetheless remains a core tool alongside the Five Forces and the value chain.
