Rethinking marketing: Peter Drucker's challenge

Just as Peter Drucker pointed out the importance of assessing whether a company's "theory of business" is relevant, marketers need to consider whether the current "theory of marketing" still fits in a world of rapid change. The author examines how Drucker challenged the theory of business at financial services firm Edward Jones, helping to identify new market opportunities. For example, he urged the company to move into metropolitan areas, which now account for 60 percent of the firm's business. The article then considers how the field of marketing needs to reexamine its own mental models. Finally, the article considers how Drucker's seminal insights on marketing, particularly his emphasis on an interdisciplinary approach, might point the way to new approaches.
