Nadella's principles, which urges leaders to "create clarity" and "generate energy," are required reading for every new manager at Microsoft, and the subject of an online course at the company.

Bezos' principles - starting with the "customer obsession" that the company often talks about - are posted on Amazon's career website for prospective job candidates and anyone else to view.
