Technology can provide competitive advantages through both cost-based and differentiation-based strategies. Cost-based strategies pursue cost advantages through economies of scale, supply chain efficiencies like Walmart, or technology that reduces costs. Differentiation strategies use technology to uniquely understand customers, deliver value in new ways, or integrate technology into products and services. Effective strategies pursue both cost leadership and differentiation, while challenges include organizational change, overreliance on costs, and maintaining unique value over time.
