How and why firms outperform each other goes to the heart of strategic management. In this chapter, we identified three generic strategies and discussed how firms are able not only to attain advantages over competitors, but also to sustain such advantages over time. Why do some advantages become long-lasting while others are quickly imitated by competitors?
The three generic strategies—overall cost leadership, differentiation, and focus—form the core of this chapter. We began by providing a brief description of each generic strategy (or competitive advantage) and furnished examples of firms that have successfully implemented these strategies. Successful generic strategies invariably enhance a firm's position vis-à-vis the five forces of that industry—a point that we stressed and illustrated with examples. However, as we pointed out, there are pitfalls to each of the generic strategies. Thus, the sustainability of a firm's advantage is always challenged because of imitation or substitution by new or existing rivals. Such competitor moves erode a firm's advantage over time.
We also discussed the viability of combining (or integrating) overall cost leadership and generic differentiation strategies. If successful, such integration can enable a firm to enjoy superior performance and improve its competitive position. However, this is challenging, and managers must be aware of the potential downside risks associated with such an initiative.
