Overview

The 80/20 Principle--that 80 percent of results flow from just 20 percent of our efforts--is one of the great secrets of highly effective people and organizations.

One of the decade's most original, provocative, and powerful books, The 80/20 Principle shows how you can achieve much more with much less effort, time, and resources, simply by concentrating on the all-important 20 percent.  Astonishingly, although the 80/20 Principle has long influenced today's world, Richard Koch is the first person to show how to use it in a systematic and practical way.

The pattern of predictable imbalance underlying the 80/20 Principle was first discovered a hundred years ago by Italian economist Vilfredo Pareto while studying income and wealth patterns.  But the pattern of "predictable imbalance," as he termed it, crops up throughout life.  In The 80/20 Principle, Koch opens our eyes to the way the principle works through a wide range of examples in business, commerce, and virtually every aspect of our lives.  For example, 20 percent of products account for 80 percent of sales and profits; similarly, 20 percent of customers account for 80 percent of revenues.

By identifying and focusing on the 20 percent of our efforts that result in the huge bulk of our success, we can leverage our efforts to vastly increase our effectiveness.  For we discover that little of what we do really counts.  By concentrating on those things that do, we can transform our effectiveness in our jobs, our careers, our businesses, and our lives.  By showing how to unlock the enormous potential of the magic 20percent, The 80/20 Principle will revolutionize your life.

What People Are Saying

Mike Goldwater
The 80/20 Principle can and should be used by every intelligent person in their daily life... It can multiply the profitability of corporations and the effectiveness of any organization. It even holds the key to raising the quality and quantity of public services while cutting their cost....

The 80/20 Principle asserts that a minotiry of causes, inputs, or effort usually lead to a majority of the results, outputs, or rewards. Taken literally, for example, 80 percent of what you achieve in your job comes from 20 percent of the time spent. Thus for all practical purposes, four fifths of the effort -- a dominant part of it -- is largely irrelevant.

Introduction: Welcome to the 80/20 Principle

For a very long time, the Pareto law [the 80/20 Principle] has lumbered the economic scene like an erratic block on the landscape; an empirical law which nobody can explain.
--Josef Steindl

The 80/20 Principle can and should be used by every intelligent person in their daily life, by every organization, and by every social grouping and form of society.  It can help individuals and groups achieve much more, with much less effort.  The 80/20 Principle can raise personal effectiveness and happiness.  It can multiply the profitability of corporations and the effectiveness of any organization.  It even holds the key to raising the quality and quantity of public services while cutting their cost.  This book, the first ever on the 80/20 Principle, is written from a burning conviction, validated in personal and business experience, that this principle is one of the best ways of dealing with and transcending the pressures of modern life.

What is the 80/20 Principle?

The 80/20 Principle asserts that a minority of causes, inputs, or effort usually lead to a majority of the results, outputs, or rewards.  Taken literally, this means that, for example, 80 percent of what you achieve in your job comes from 20 percent of the time spent.  Thus for all practical purposes, four-fifths of the effort--a dominant part of it--is largely irrelevant.  This is contrary to what people normally expect.

So the 80/20 Principle states that there is an inbuilt imbalance between causes and results, inputs and outputs, and effort andreward.  A good benchmark for this imbalance is provided by the 80/20 relationship: a typical pattern will show that 80 percent of outputs result from 20 percent of inputs; that 80 percent of consequences flow from 20 percent of causes; or that 80 percent of results come from 20 percent of effort.

In business, many examples of the 80/20 Principle have been validated.  Twenty percent of products usually account for about 80 percent of dollar sales value; so do 20 percent of customers.  Twenty percent of products or customers usually also account for about 80 percent of an organization's profits.

In society, 20 percent of criminals account for 80 percent of the value of all crime.  Twenty percent of motorists cause 80 percent of accidents.  Twenty percent of those who marry comprise 80 percent of the divorce statistics (those who consistently remarry and redivorce distort the statistics and give a lopsidedly pessimistic impression of the extent of marital fidelity).  Twenty percent of children attain 80 percent of educational qualifications available.

In the home, 20 percent of your carpets are likely to get 80 percent of the wear.  Twenty percent of your clothes will be worn 80 percent of the time.  And if you have an intruder alarm, 80 percent of the false alarms will be set off by 20 percent of the possible causes.

The internal combustion engine is a great tribute to the 80/20 Principle.  Eighty percent of the energy is wasted in combustion and only 20 percent gets to the wheels; this 20 percent of the input generates 100 percent of the output!

Pareto's discovery: systematic and predictable lack of balance

The pattern underlying the 80/20 Principle was discovered in 1897, about 100 years ago, by Italian economist Vilfredo Pareto (1848-1923).  His discovery has since been called many names, including the Pareto Principle, the Pareto Law, the 80/20 Rule, the Principle of Least Effort, and the Principle of Imbalance; throughout this book we will call it the 80/20 Principle.  By a subterranean process of influence on many important achievers, especially business people, computer enthusiasts and quality engineers, the 80/20 Principle has helped to shape the modern world.  Yet it has remained one of the great secrets of our time--and even the select band of cognoscenti who know and use the 80/20 Principle only exploit a tiny proportion of its power.

So what did Vilfredo Pareto discover?  He happened to be looking at patterns of wealth and income in nineteenth-century England.  He found that most income and wealth went to a minority of the people in his samples.  Perhaps there was nothing very surprising in this.  But he also discovered two other facts that he thought highly significant.  One was that there was a consistent mathematical relationship between the proportion of people (as a percentage of the total relevant population) and the amount of income or wealth that this group enjoyed.  To simplify, if 20 percent of the population enjoyed 80 percent of the wealth, then you could reliably predict that 10 percent would have, say, 65 percent of the wealth, and 5 percent would have 50 percent.  The key point is not the percentages, but the fact that the distribution of wealth across the population was predictably unbalanced.

Pareto's other finding, one that really excited him, was that this pattern of imbalance was repeated consistently whenever he looked at data referring to different time periods or different countries.  Whether he looked at England in earlier times, or whatever data were available from other countries in his own time or earlier, he found the same pattern repeating itself, over and over again, with mathematical precision.

Was this a freak coincidence, or something that had great importance for economics and society?  Would it work if applied to sets of data relating to things other than wealth or income?  Pareto was a terrific innovator, because before him no one had looked at two related sets of data--in this case, the distribution of incomes or wealth, compared to the number of income earners or property owners--and compared percentages between the two sets of data.  (Nowadays this method is commonplace and has led to major breakthroughs in business and economics.)

Sadly, although Pareto realized the importance and wide range of his discovery, he was very bad at explaining it.  He moved on to a series of fascinating but rambling sociological theories, centering on the role of elites, which were hijacked at the end of his life by Mussolini's fascists.  The significance of the 80/20 Principle lay dormant for a generation.  While a few economists, especially in the US, realized its importance, it was not until after the Second World War that two parallel yet completely different pioneers began to make waves with the 80/20 Principle.

1949: Zipf's Principle of Least Effort

One of these pioneers was the Harvard professor of philology, George K Zipf.  In 1949 Zipf discovered the "Principle of Least Effort," which was actually a rediscovery and elaboration of Pareto's principle.  Zipf's principle said that resources (people, goods, time, skills, or anything else that is productive) tended to arrange themselves so as to minimize work, so that approximately 20-30 per cent of any resource accounted for 70-80 per cent of the activity related to that resource.

Professor Zipf used population statistics, books, philology, and industrial behavior to show the consistent recurrence of this unbalanced pattern.  For example, he analyzed all the Philadelphia marriage licenses granted in 1931 in a 20-block area, demonstrating that 70 percent of the marriages occurred between people who lived within 30 percent of the distance.

Incidentally, Zipf also provided a scientific justification for the messy desk by justifying clutter with another law: frequency of use draws near to us things that are frequently used.  Intelligent secretaries have long known that files in frequent use should not be filed!

1951: Juran's Rule of the Vital Few and the rise of Japan

The other pioneer of the 80/20 Principle was the great quality guru, Romanian-born U.S. engineer Joseph Moses Juran (born 1904), the man behind the Quality Revolution of 1950-90.  He made what he alternately called the "Pareto Principle" and the "Rule of the Vital Few" virtually synonymous with the search for high product quality.

In 1924, Juran joined Western Electric, the manufacturing division of Bell Telephone System, starting as a corporate industrial engineer and later setting up as one of the world's first quality consultants.

His great idea was to use the 80/20 Principle, together with other statistical methods, to root out quality faults and improve the reliability and value of industrial and consumer goods.  Juran's path-breaking Quality Control Handbook was first published in 1951 and extolled the 80/20 Principle in very broad terms: The economist Pareto found that wealth was nonuniformly distributed in the same way [as Juran's observations about quality losses].  Many other instances can be found--the distribution of crime amongst criminals, the distribution of accidents among hazardous processes, etc.  Pareto's principle of unequal distribution applied to distribution of wealth and to distribution of quality losses.

No major U.S. industrialist was interested in Juran's theories.  In 1953 he was invited to Japan to lecture, and met a receptive audience.  He stayed on to work with several Japanese corporations, transforming the value and quality of their consumer goods.  It was only once the Japanese threat to U.S. industry had become apparent, after 1970, that Juran was taken seriously in the West.  He moved back to do for U.S. industry what he had done for the Japanese.  The 80/20 Principle was at the heart of this global quality revolution.  

From the 1960s to the 1990s: progress from using the 80/20 Principle

IBM was one of the earliest and most successful corporations to spot and use the 80/20 Principle, which helps to explain why most computer systems specialists trained in the 1960s and 1970s are familiar with the idea.

In 1963, IBM discovered that about 80 percent of a computer's time is spent executing about 20 percent of the operating code.  The company immediately rewrote its operating software to make the most-used 20 percent very accessible and user friendly, thus making IBM computers more efficient and faster than competitors' machines for the majority of applications.

Those who developed the personal computer and its software in the next generation, such as Apple, Lotus, and Microsoft, applied the 80/20 Principle with even more gusto to make their machines cheaper and easier to use for a new generation of customers, including the now celebrated "dummies" who would previously have given computers a very wide berth.

Winner take all

A century after Pareto, the implications of the 80/20 Principle have surfaced in a recent controversy over the astronomic and ever-rising incomes going to superstars and those very few people at the top of a growing number of professions.  Film director Steven Spielberg earned $165 million in 1994.  Joseph Jamial, the most highly paid trial lawyer, was paid $90 million.  Merely competent film directors or lawyers, of course, earn a tiny fraction of these sums.

The twentieth century has seen massive efforts to level incomes, but inequality, removed in one sphere, keeps popping up in another.  In the United States from 1973 to 1995, average real incomes rose by 36 percent, yet the comparable figure for nonsupervisory workers fell by 14 percent.  During the 1980s, all of the gains went to the top 20 percent of earners, and a mind-boggling 64 percent of the total increase went to the top 1 percent!  The ownership of shares in the United States is also heavily concentrated within a small minority of households: 5 percent of U.S. households own about 75 percent of the household sector's equity.  A similar effect may be seen in the role of the dollar: almost 50 percent of world trade is invoiced in dollars, far above America's 13 percent share of world exports.  And, while the dollar's share of foreign exchange reserves is 64 percent, the ratio of American GDP to global output is just over 20 percent.  The 80/20 Principle will always reassert itself, unless conscious, consistent, and massive efforts are made and sustained to overcome it.

Why the 80/20 Principle is so Important

The reason that the 80/20 Principle is so valuable is that it is counter-intuitive.  We tend to expect that all causes will have roughly the same significance.  That all customers are equally valuable.  That every bit of business, every product, and every dollar of sales revenue is as good as any other.  That all employees in a particular category have roughly equivalent value.  That each day or week or year we spend has the same significance.  That all our friends have roughly equal value to us.  That all inquiries or phone calls should be treated in the same way.  That one university is as good as another.  That all problems have a large number of causes, so that it is not worth isolating a few key causes.  That all opportunities are of roughly equal value, so that we treat them all equally.

We tend to assume that 50 percent of causes or inputs will account for 50 percent of results or outputs.  There seems to be a natural, almost democratic, expectation that causes and results are generally equally balanced.  And, of course, sometimes they are.  But this "50/50 fallacy" is one of the most inaccurate and harmful, as well as the most deeply rooted, of our mental maps.  The 80/20 Principle asserts that when two sets of data, relating to causes and results, can be examined and analyzed, the most likely result is that there will be a pattern of imbalance.  The imbalance may be 65/35, 70/30, 75/25, 80/20, 95/5, or 99.9/0.1, or any set of numbers in between.  However, the two numbers in the comparison don't have to add up to 100.

The 80/20 Principle also asserts that when we know the true relationship, we are likely to be surprised at how unbalanced it is.  Whatever the actual level of imbalance, it is likely to exceed our prior estimate.  Executives may suspect that some customers and some products are more profitable than others, but when the extent of the difference is proved, they are likely to be surprised and sometimes dumbfounded.  Teachers may know that the majority of their disciplinary troubles or most truancy arises from a minority of pupils, but if records are analyzed the extent of the imbalance will probably be larger than expected.  We may feel that some of our time is more valuable than the rest, but if we measure inputs and outputs the disparity can still stun us.

Why should you care about the 80/20 Principle?  Whether you realize it or not, the principle applies to your life, to your social world, and to the place where you work.  Understanding the 80/20 Principle gives you great insight into what is really happening in the world around you.

The overriding message of this book is that our daily lives can be greatly improved by using the 80/20 Principle.  Each individual can be more effective and happier.  Each profit-seeking corporation can become very much more profitable.  Each nonprofit organization can also deliver much more useful outputs.  Every government can ensure that its citizens benefit much more from its existence.  For everyone and every institution, it is possible to obtain much more that is of value and avoid what has negative value, with much less input of

    Time is not the enemy!

    This is one of the few books I have borrowed from the library and then gone to a bookstore to purchase a copy for my bookshelf. I love this book for its mind-expanding qualities - it is inspirational and provides food for the imagination. Written in an easy style, Richard Koch is both edifying and entertaining. I especially like what he has to say about time. In particular: * Time is not the enemy. If we make good use of only 20% of our time, there is no shortage of it. * Time gone is not time lost. * We should aim to collaborate with time: `Insight and value are likely to come from placing ourselves in a comfortable, relaxed and collaborative position towards time'. [p163] * Action drives out thought. It is because we have so much time we squander it. * Be eccentric and unconventional with time - you can not conform to everyone's wishes. * Under no circumstances give everyone a fair share of your time ... ... You may need to read the book to see how he came to some of these conclusions! Whenever I find myself busy beyond belief it is good to be reminded that most of what I am doing is of little importance. However - when faced with one of those moments (or decisions) that are much more valuable than all the rest - it is helpful to be reminded, and encouraged, to `do something radical and stop tinkering around the edges'. I bought this book so I could refer to it whenever I feel I have lost focus and need some sage advice. This book does not contain all the answers, and the theory only works to a point, but nonetheless it is a terrific 'thought jump starter' and I highly recommend it.
