Fifteen years ago Richard Koch introduced the world to the 80/20 Principle. Now he shows managers how to use the Principle to achieve exceptional results at work - without stress or long hours. A large number of managers - especially in these difficult times - feel completely overwhelmed. Their inboxes are overflowing, they constantly struggle to finish their to-do lists and they stay at work longer than they would like to, leaving little time for the things that really matter. Luckily there is a way for managers to enjoy work and build a successful and fulfilling career without stress or long hours. In his bestselling book The 80/20 Principle, Richard Koch showed readers how to put the 80/20 Principle - the idea that 80 per cent of results come from just 20 per cent of effort - into practice in their personal lives. Now he demonstrates the few things you need to do in the workplace to multiply the results you achieve.
