Review: 'The 80/20 Principle' by Robert Koch

Would you like to learn how to get more done with less effort, eliminate wasteful activities, and sell more to your best customers? This book can show you how.

In The 80/20 Principle, Richard Koch thoroughly examines Pareto's Law – the observation that, in any given context, "a minority of causes, inputs, or effort usually leads to a majority of the results, outputs, or rewards." This inherent nonlinearity is present in all aspects of life, and by paying attention to your efforts and results, you can identify major opportunities for improvement in every aspect of your life and business.

By identifying the critical 20% of causes and focusing time and resources on optimizing them, it is possible to realize enormous gains in productivity in relatively short order. While Pareto's Law is typically used for sales, customer, or inventory analysis, The 80/20 Principle examines personal and management applications as well, including priority setting and work/life balance.

Focusing on the 20% of efforts that create 80% of results isn't always easy, but it can revolutionize your business and the quality of your life.
