The Halo Effect

November 13, 2006
This tart takedown of fashionable management theories is a refreshing antidote to the glut of simplistic books about achieving high performance. Rosenzweig, a veteran business manager turned professor, argues that most popular business ideas are no more than soothing platitudes that promise easy success to harried managers. Consultants, journalists and other pundits tap scientifically suspect methods to produce what he calls "business delusions": deeply flawed and widely held assumptions tainted by the "halo effect," or the need to attribute sweeping positive qualities to any company that has achieved success. Following these delusions might provide managers with a comforting story that helps them frame their actions, but it also leads them to gross simplification and to ignore the constant demands of changing technologies, markets, customers and situations. Mega-selling books like Good to Great
, Rosenzweig argues, are nothing more than comforting, highbrow business fables. Unfortunately, Rosenzweig hedges his own principles for success so much that managers will find little practical use for them. His argument about the complexity of sustained achievement, and his observation that success comes down to "shrewd strategy, superb execution and good luck," may end up limiting the market for this smart and spicy critique.
