This Amazon Organizational Chart is hierarchical. The senior management team consists of three CEOs and three senior vice presidents in charge of various critical aspects of the business and reports directly to CEO Andy Jassy. Amazon's organizational structure incorporates numerous small teams that handle multiple aspects of the company. Amazon founder and former CEO Jeff Bezos is credited with popularizing the "two-pizza rule." According to this rule, meetings should be held in groups small enough that everyone can be fed with only two pizzas. The "two pizza rule" is still in effect today, thanks to new CEO Andy Jassy. Amazon's stability is one of its defining characteristics. Specifically, the largest internet company by revenue has "very little turnover among its most important power players, with many remaining in place."
