According to conventional wisdom, companies resemble organisms destined to pass through the stages of start-up, scaling, maturity and decline. In reality, business opportunities & #8212; and not firms & #8212; pass through these stages, and most organizations consist of multiple opportunities arrayed across the different stages of the life cycle. Executives who understand this crucial distinction can view their organization as a portfolio of opportunities that requires constant re-jiggering to balance the demands of the present with the promise of the future. The authors suggest that, when assessing any opportunity portfolio, executives should remain on the lookout for the following common pathologies: waiting too long to exit a declining business, failing to salvage usable pieces of a business that is shutdown, shunning promising new markets because of an overly conservative fiscal approach, trying to scale too many business opportunities so that none of them receives the necessary resources), applying the same management style to business opportunities at different life cycle stages, and erring on the side of loss aversion.

Early research in e-commerce projected that online retailing would spiral into a never-ending price war, but recent research has shown that customers are more likely to pay higher prices to online retailers of high quality that they trust. But how do customers evaluate quality in online retailing? What are the specific aspects of an online transaction that customers value and use to distinguish one site from another? The authors explored these issues by surveying customers who had recently engaged in an online retail transaction to determine how they evaluate the quality of their experiences with online retailers. The results demonstrated that customers' perceptions of quality and satisfaction with online purchases depend upon three things: interaction with the Web site, delivery of the product and how prepared retailers are to address problems when they occur. Of the three, product delivery has the strongest influence on customers' satisfaction and future purchase intentions. The authors further break down each of the three aspects of quality to create a complete picture of what it takes to build a trusting relationship with customers in an e-commerce environment.

Multicultural experience tends to facilitate creative thinking and problem solving.

Innovation is typically a group effort, but how exactly do researchers collaborate with one another to innovate? To answer this question, the authors compiled a dataset identifying all co-authorship relationships of U.S. patent inventors from 1975 through 1999. That dataset revealed that the social network of innovators is a "small world," with various clusters of people interconnected by different "gatekeepers," individuals who bridge one group with another. Historically, engineers and scientists tended to work within local clusters of collaboration that were isolated within a company. Recently, though, people have become increasingly mobile, changing jobs with greater frequency, and these formerly isolated clusters have begun to interconnect into larger networks through which information flows more freely between companies. Such environments provide both strategic opportunity and potential threat: They can increase creativity within a company, but they also aid in the diffusion of creative knowledge to other firms through personnel and knowledge transfer. The trick, then, is to manage innovation in ways that exploit the opportunities while minimizing the risks.

It is common for senior managers to look for meaningful correlations within their businesses -- for example, to search for the most direct drivers of profitability. However, managers often overreach, overstating relationships that are tenuous at best or may not even exist. In support of this view, the authors, who are consultants in the area of customer loyalty, cite their own recent investigation into common beliefs about customer loyalty (that is, "It costs more to acquire a customer than to retain a customer"), many of which proved to be unfounded. In general, the authors argue, professional managers are too willing to suspend disbelief about cause-and-effect relationships. They allow biases toward a specific business outcome to shape their interpretation of causes and effects. The authors refer to this phenomenon as management teleology. The tendency to hold onto the most rewarding view of events, the authors offer, is not unique to managers. However, when managers substitute beliefs for knowledge and don't acknowledge the leap, they put their businesses at risk. New management ideas will always challenge current practices. But before managers embrace new ways of approaching problems, they should require a higher level of analytic rigor. They need to cultivate the habit of questioning the underlying assumptions of their own views, and be open to ideas that come from the outside.

Which jobs are good candidates for global disaggregation?

The colonization of American manufacturing by distributors has pushed U.S. companies overseas.

The author re-examines the role of IT as a commodity and considers whether IT can still be used to provide strategic advantage. In discussing regulation, outsourcing relationships and corporate dependence on IT, this article further clarifies the argument that IT will soon be handled by larger corporate utilities. While agreeing that most IT functions can be outsourced to utility-style providers, the article suggests that in-house corporate computing can still provide a strategic advantage. By examining failed IT outsourcing relationships, the author identifies key aspects of IT, including auditing and reporting procedures and customer-facing resources that are too important to a firm's success to outsource. The author argues that to better exploit these advantages, managers should embrace the fact that IT is no different than any other corporate function, instead of placing it in its own silo separate from other business practices. Only then will the real commoditization of IT be complete and the long-promised benefits be seen.
