The Halo Effect: How Managers let Themselves be Deceived

Front Cover
Simon and Schuster, Dec 9, 2008 - Business & Economics - 256 pages
Why do some companies prosper while others fail? Despite great amounts of research, many of the studies that claim to pin down the secret of success are based in pseudoscience. THE HALO EFFECT is the outcome of that pseudoscience, a myth that Philip Rosenzweig masterfully debunks in THE HALO EFFECT.

THE HALO EFFECT highlights the tendency of experts to point to the high financial performance of a successful company and then spread its golden glow to all of the company's attributes - clear strategy, strong values, and brilliant leadership. But in fact, as Rosenzweig clearly illustrates, the experts are not just wrong, but deluded.

Rosenzweig suggests a more accurate way to think about leading a company, a robust and clearheaded approach that can save any business from ultimate failure.
