Book excerpt: Modern business is a blur of jargon with thousands of books all purporting to hold the key to relentless success. The working reality is often very different. This book distils and summarises all the best current thinking in business so that you can become an authority yourself - and quickly. As well as saving hundreds of hours of reading time, the reader is able to grasp ideas accurately, explain them authoritatively to colleagues and avoid being hoodwinked by those who claim to understand a concept when in fact they have got the wrong end of the stick. Books profiled include Nudge, Freakonomics, and Built to Last.
