Information technology matters to business success because it directly affects the mechanisms through which they create and capture value to earn a profit: IT is thus integral to a firm's business-level strategy. Much of the extant research on the IT/strategy relationship, however, inaccurately frames IT as only a functional-level strategy. This widespread under-appreciation of the business-level role of IT indicates a need for substantial retheorizing of its role in strategy and its complex and interdependent relationship with the mechanisms through which firms generate profit. Using a comprehensive framework of potential profit mechanisms, we argue that while IT activities remain integral to the functional-level strategies of the firm, they also play several significant roles in business strategy, with substantial performance implications. IT affects industry structure and the set of business-level strategic alternatives and value-creation opportunities that a firm may pursue. Along with complementary organizational changes, IT both enhances the firm's current (ordinary) capabilities and enables new (dynamic) capabilities, including the flexibility to focus on rapidly changing opportunities or to abandon losing initiatives while salvaging substantial asset value. Such digitally attributable capabilities also determine how much of this value, once created, can be captured by the firm-and how much will be dissipated through competition or through the power of value chain partners, the governance of which itself depends on IT. We explore these business-level strategic roles of IT and discuss several provocative implications and future research directions in the converging information systems and strategy domains.
New entrants in many industries are able to challenge the business of historically dominant firms. In many markets, dominant players have pursued pricing and service policies that, although once highly effective, now make their markets attractive targets for aggressive new entrants. The entrants' strategies rely on lower overhead costs, new technologies, alternative distribution channels, and the active targeting of profitable customers. Several factors will make it possible for entrants to attack dominant players; simplistic historical pricing mistakes or policies of promising or providing universal service will make it attractive for new entrants to attack. Restrictions on the flexibility of incumbents--both externally and internally imposed--may make it difficult for dominant players to defend themselves effectively against attack by more flexible entrants with cream-skimming strategies and newer technology. We develop a set of alternatives for incumbent firms facing increasing "contestability" in their markets and the threat of agile entrants.
