February 11, 2015 Why You Should Be Careful About How You Present Performance Metrics If research participants were informed that their error rate on a task was 5%, compared with an unseen other person's score of 2%, they rated their own performance more poorly than if they were told their success rate was 95% and the other person's was 98% – even though the two statements convey exactly the same information. That's because the difference between 5 and 2 looms much larger in people's minds than the difference between 95 and 98, say Jessica Y.Y. Kwong of the Chinese University of Hong Kong and Kin Fai Ellick Wong of Hong Kong University of Science and Technology. People don't interpret numbers objectively; instead they base their opinions on how numbers make them "feel," the research shows. SOURCE: Fair or Not Fair?

FEATURED PRODUCT Blue Ocean Strategy, Expanded Edition HBR Press Book This global bestseller, embraced by organizations and industries worldwide, challenges everything you thought you knew about the requirements for strategic success. Now updated with fresh content from the authors, Blue Ocean Strategy argues that cutthroat competition results in nothing but a bloody red ocean of rivals fighting over a shrinking profit pool. Based on a study of 150 strategic moves (spanning more than 100 years across 30 industries), the authors argue that lasting success comes not from battling competitors but from creating "blue oceans"—untapped new market spaces ripe for growth. Blue Ocean Strategy presents a systematic approach to making the competition irrelevant and outlines principles and tools any organization can use to create and capture their own blue oceans.
