Very recently, Fortune magazine had Jeff Bezos of Amazon at the top of its list of the greatest leaders in the world. The article praised him for being the father of e-retailing, cloud services, and e-books. When considering what has enabled Bezos and Amazon to achieve at such a level, I am reminded of a past Fortune article that described how he requires his people to write thorough documents when they want to propose an idea/product/direction for Amazon to pursue. His view is that there in no way to write a persuasive, thorough proposal and not have clear thinking.
