Most of us organizing and productivity consultants have heard of the Pareto Principle or 80/20 Rule by now and maybe even use it with our clients to make them understand how so much of what we have, we don’t use. What was once created by an economist, Vilfredo Pareto, as a mathematical formula in 1906 to describe unequal distribution of wealth in Italy, has actually become a universal principle and an effective tool for management. The 80/20 Rule means that in anything, a few (20 percent) are vital, and many (80 percent) are trivial.
