The 80/20 rule revisited

I have written about the 80/20 rule both in this blog and in my books.  It is a useful tool for may situations.

I learned something new about it today. It is also called Pareto Principle, after 19th Century thinker Vilfedo Pareto. He described the distribution of probable results and options as a mathematical function that is then graphed.

The resulting graph gets divided into the vital few and the trivial many.

Thanks to ongoing ITIL training for this insight!
