The 80/20 Principle Guide Beginners

Chapter 2 explains how you can put the 80/20 Principle into practice and explores the distinction between 80/20 Analysis and 80/20 Thinking, both of which are useful methods derived from the 80/20 Principle. 80/20 Analysis is a systematic, quantitative method of comparing causes and effects. 80/20 Thinking is a broader, less precise, and more intuitive procedure, comprising the mental models and habits that enable us to hypothesize what are the important causes of anything important in our lives, to identify these causes, and to make sharp improvements in our position by redeploying our resources accordingly.
Part Two: Corporate Success Needn’t Be a Mystery summarizes the most powerful business uses of the 80/20 Principle. These uses have been tried and tested and found to be of immense value yet remain curiously unexploited by most of the business community. There is little in my summary that is original, but anyone seeking major profit improvement, whether for a small or large business, should find this a very useful primer and the first ever to appear in a book.
Part Three: Work Less, Earn and Enjoy More shows how the 80/20 Principle can be used to raise the level at which you are operating in both your work and personal life. This is a pioneering attempt to apply the 80/20 Principle on a novel canvas; and the attempt, although I am sure it is imperfect and incomplete in many ways, does lead to some surprising insights. For example, 80 percent of the typical person’s happiness or achievement in life occurs in a small proportion of that life. The peaks of great personal value can usually be greatly expanded. The common view is that we are short of time. My application of the 80/20 Principle suggests the reverse: that we are actually awash with time and profligate in its abuse.
Part Four: The 80/20 Future draws the themes together and positions the 80/20 Principle as the greatest secret engine of progress available to us all. It hints at the uses that could be made of the 80/20 Principle for the public good as well as for corporate wealth creation and personal advancement.
WHY THE 80/20 PRINCIPLE BRINGS GOOD NEWS
I want to end this introduction on a personal rather than a procedural note. I believe that the 80/20 Principle is enormously hopeful. Certainly, the principle brings home what may be evident anyway: that there is a tragic amount of waste everywhere, in the way that nature operates, in business, in society, and in our own lives. If the typical pattern is for 80 percent of results to come from 20 percent of inputs, it is necessarily typical too that 80 percent, the great majority, of inputs are having only a marginal - 20 percent - impact.
The paradox is that such waste can be wonderful news, if we can use the 80/20 Principle creatively, not just to identify and castigate low productivity but to do something positive about it. There is enormous scope for improvement, by rearranging and redirecting both nature and our own lives. Improving on nature, refusing to accept the status quo, is the route of all progress: evolutionary, scientific, social, and personal. George Bernard Shaw put it well: “The reasonable man adapts himself to the world. The unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.”15
The implication of the 80/20 Principle is that output can be not just increased but multiplied, if we can make the low-productivity inputs nearly as productive as the high-productivity inputs. Successful experiments with the 80/20 Principle in the business arena suggest that, with creativity and determination, this leap in value can usually be made.
