Pareto's Principle~~ 20/80 Rule

Daily reminder that 20% of your work is really important in any given moment; therefore, focus 80 % of your time, energy and talents that 20 percent.

Don't just "work smart", work smart on the “right things”.

How it can help you

How It Can Help You

  • The value of the Pareto Principle is that it reminds us to focus on the 20% that matters.

  • Of the things we do, only 20% really matters, in any given moment.

  • Those 20% produce 80% of the results.

  • Identify and focus on those things.

  • When the crisis drills of the day begin to sap our time, energy and patience remind yourself of the 20 % you need to focus on.

  • If something in the schedule has to slip, make sure it's not part of that 20%

The superstars

The Superstars!

  • 20 % of people produce 80 % of the results.

  • Therefore, helping the good become better is a better use of time than helping the great become terrific!

The vital few what it means

The Vital Few: What It Means

  • The 80/20 Rule means that in anything a few (20 %) are vital and many (80 %) are trivial.

  • In Pareto's case it meant 20 % of the people owned 80 % of the wealth.

  • In Juran's work he identified 20 % of the defects (error types) causing 80 % of the problems.

Where it came from

The original observation was in connection with income and wealth.

Pareto noticed that 20% of the population owned 80% of Italy's wealth.

After Pareto made his observation, he created a formula.

Many others observed similar phenomena in their own areas of expertise.

Quality Management pioneer, Dr. Juran, in the 1930s recognized a Universal Principle he called the “Vital Few & Trivial Many".

As a result, the principle that 20 percent of something always are responsible for 80 percent of the results.

You can apply the 80/20 Rule to almost anything, from the science of management to the physical world.

Where It Came From

Let s take a look

Let’s Take a Look!

  • 20% of stock takes up 80% of space.

  • 20% of your suppliers provide 80% your stock.

  • 20% of staff account for 80% sales.

  • 20% staff will cause 80% of problems AND

  • Another 20% staff will provide 80% of production.

  • It works both ways.

The principle is reflected in the Human Gestation period. The embryonic period constitutes 20% of the whole, with fetal growth taking up the rest of the time.

20% of carpet accounts for 80% of wear.

20% of the time spent on a project accounts for 80%

of the results.
