Prof. Juran later extended it to many practical situations like 80% of sales in an organization come from 20% of its customers and so on.
The Global wealth report 2016 published by Credit Suisse yesterday reveals a couple of startling points.
1. Top 10% of the world population hold 89% of global wealth which in 2016 is estimated to be $256 trillion, ie top 10% of global population (7400 million), 740 million hold $228 trillion wealth and the rest 6660 million people of the world own the balance $28 trillion of global wealth.
Pareto has been proved wrong yet again by global economic leaders and Pareto's 80-20 rule looks to be changing to Pareto's 90-10 rule !!
2. 96% of the global adult population ( > 18-21 years age) remains at the base of the wealth pyramid with wealth below $10,000 ..
