Product Description

Review

"In "The Halo Effect," Phil Rosenzweig has done us all a great service by speaking the unspeakable. His iconoclastic analysis is a very welcome antidote to the kind of superficial, formulaic, and dumbed-down matter that seems to be the current stock in trade of many popular business books. It's the right book at the right time."-- John R. Kimberly, Henry Bower Professor of Entrepreneurial Studies, The Wharton School, University of Pennsylvania

Product Description

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.

More About the Author

Phil Rosenzweig is professor at IMD in Lausanne, Switzerland, one of the world's leading institutes of executive education. He is author of THE HALO EFFECT (2007) described by The Wall Street Journal as "a trenchant view of business and business advice," and lauded by Nassim Nicholas Taleb as "one of the most important management books of all time."

Phil's new book, LEFT BRAIN, RIGHT STUFF, extends our understanding of decision making. It examines decision making in complex real-world settings, where we can influence outcomes and often have to outperform rivals. Entertaining, practical, and often surprising, LEFT BRAIN, RIGHT STUFF takes a fresh look at topics like confidence and overconfidence, the winner's curse, the illusion of control, and the power of positive thinking.

5.0 out of 5 stars Debunking business pseudo-science 6 July 2007
Format:Hardcover
I just finished reading Phil Rosenzweig's book "The Halo Effect...and the Eight Other Business Delusions That Deceive Managers". This book takes aim at the general run of business books and, in particular, their tendency to dress up vivid stories as scientific study. Phil does not seem to have anything against stories per se, nor does he disagree with some of the advice given in the books. What he takes issue with is the focus on a single, definitive "scientific" set of recommendations when there is no real scientific rigor behind them.

He lays out 9 specific delusions and shows how they distort the advice in management books:
- The Halo Effect - tending of analysis of a company to reflect only the overall results
- The Delusion of Correlation and Causality - the lack of proof of causality in many situations
- The Delusion of Single Explanations - one factor is unlikely to be the reason for success or failure
- The Delusion of Connecting the Winning Dots - problems with only considering "winners"
- The Delusion of Rigorous Research - mistaking large volumes of data for good data
- The Delusion of Lasting Success - most companies trend to the mean eventually
- The Delusion of Absolute Performance - companies can do well and still fail if a competitor does better
- The Delusion of the Wrong End of the Stick - successful companies may do various things but that does not mean that doing those things will make you successful
- The Delusion of Organizational Physics - business organizations are just not that predictable

Phil uses various stories to show how the perception of companies and leaders changes when the company's performance does.

5.0 out of 5 stars Straight talk about corporate results 2 Mar 2007
By Rolf Dobelli TOP 500 REVIEWER
Format:Hardcover
This serious book will change the way many people think about the pursuit of managerial excellence and, indirectly, about the criteria they use for managing (and coincidentally) investing. Phil Rosenzweig provocatively challenges prevailing concepts about the traits that drive corporate performance. He asks revealing questions about previous research assumptions that labeled companies "excellent." It seems that earlier accolades about "the best" companies - including the claims in some blockbuster books - were based on faulty research techniques that led authors to mistakenly attribute achievements to companies that did not accomplish them or could not sustain them. Rosenzweig distills his compelling ideas clearly, and buttresses his case with specific examples and original research, adding to the book's power. As a result, we would compare this very readable, focused book to fine brandy: palatable, enjoyable, memorable, a little heavy - and imbued with the potential to change your mind. Highly recommended.

5.0 out of 5 stars Buy it for your own manager! 15 April 2009
Format:Paperback
This is a definitive book about critical thinking in the context of business success. A lot of people claim to understand why businesses succeed or fail, whether in journalism such as Fortune magazine, in bestselling books such as In Search of Excellence or in academia. With admirable clarity, Rosenzweig sets out the scientific failings of these, boiling down the errors to a list of nine "delusions" which infect even some of the most prestigious business research.

For instance, business writers neglect the role of external factors in performance (similar to what Taleb's Fooled by Randomness: The Hidden Role of Chance in Life and in the Markets says about the financial sector). They mistake correlation for causality. They amass huge corpuses of data without addressing the known biases in that data. The Halo Effect of the title is an example of what is known in psychology as attribute substitution. Researchers want to measure a company's customer focus (or strategic leadership, commitment to its people, etc.) to correlate against performance (such as profitability). However, customer focus is incredibly hard to measure, so in practice the estimates are based on the company's profitability. It shouldn't be surprising that this gives a strong positive correlation, as they are in effect correlating a variable against itself.

The book considers a succession of cases where companies were described as well-led, customer focused and innovative when their share price increased, but as soon as their fortunes changed suddenly "became" complacent, reckless or outdated in the eyes of commentators, or vice versa. It looks in detail at some of the books that claim to offer the secrets of success.

Format:Paperback
Most management literature is based on using cases or surveys to deduce the underlying behaviour that makes a company perform great or bad. The basic premise is, that we can isolate the generic factors that make a company great. This book is a much needed anti-thesis to this prevailing "wisdom".

The author first takes us through the two cases (yes, thats a bit ironic) of Cisco and ABB. Two companies who in their prime could do nothing wrong, only later to become ridiculed as badly managed companies. Convincingly, the author argues that we attribute positive and negative behaviour to a company depending on how it performs, rather than determine it's performance based on it's behaviour.

The book then takes us through a series of delusions, each hammering a nail through common 'halos'. The author reminds us, that cases are fine to learn from, as long as we take them as anecdotes and stories, and not as scientific truth. Some of the halos seems a bit overlapping, and toward the end, the book becomes a bit repetitive.

But still, this is a book that give you a clear perspective on what is wrong with most management literature (I mean 90% or more). This title ought to be required reading before reading as much as one piece of traditional business literature.

But better late, than never. A true eye-opener!
