The Wall Street Journal’s recently released ranking of the Management Top 250 offers a holistic appraisal of the corporate effectiveness of America’s largest public companies. The rankings are based on the Drucker model and measurement system developed by our team at the Drucker Institute. Behind the top 250 is a longer list of 693 large-cap, U.S. and Canadian firms that were ranked by the institute. These rankings and the underlying dimensional ratings shed light on the role of intangibles, such as customer satisfaction, in driving business success. The conceptual foundation for our work is drawn from the writings of the late Peter Drucker, generally regarded as the “father of modern management,” who also commented on marketing and customer satisfaction saying, “To satisfy the customer is the mission and purpose of every business.” Les mer her
