Now that I have my body armor on….I was surprised when someone emailed me the video below saying I would be “shocked” to see how unequally wealth is distributed in the USA. We generalize about this 80/20 metric, but even with the sloppy math, the ratio is uncannily accurate in our world. When the literature refers to the Pareto or the power law distribution, this generally means that the distribution has Pareto tails, meaning that it takes this form for y large. Using the 80/20 Rule to Help Productivity, Understand Team Culture and the Role of Clear Expectations in Success, Work Life a Mess? Earlier we mentioned that company revenues come from a small portion of the total customer base. Focus on any documentation issues, and take corrective action as needed. Pareto’s principle is a useful construct when analyzing efforts and outcomes. Most of the time, we are referencing Pareto's Rule without applying rigorous mathematical analysis to the situation. Use it liberally, but don’t forget that 20% of anything is not an insignificant amount. I’m really more interested in the facts. In many societies, the richest ten percent control more than half of the total … He could not know it, but in time that rule would be found to apply with uncanny accuracy to many situations and be useful in many disciplines, including the study of business productivity.

It certainly doesn’t represent an optimal environment and it definitely isn’t fair. Other examples you may have encountered include: There are a nearly unlimited number of examples that we tend to apply the 80/20 rule to in our personal and working lives. While it may be satisfying to cross off a large number of the smaller issues, the 80/20 rule suggests you focus on the few more important items that will generate the most significant results. rather that a large proportion of process variation is associated with a small proportion of the process variables. Pareto distribution or the power law has the following counter-cumulative distribution function: G(y) 1 Pr[y˜ y] = Gy l, where l 1 is the shape parameter. History of Pareto Distribution. You can see the video below, but in essence, it shows us how roughly 85% of the wealth in the USA is owned by the top 15% of the population. The Pareto Principle (also known as the 80/20 rule) was discovered by Italian economist Vilfredo Pareto who found it alarming that 80% of Italy’s property was owned by just 20% of the population. The 80/20 rule has many applications in our work and personal lives, but there are minefields here, too.
