Bezos and other Amazon executives wanted the whole effort to move even faster. They set “S-team goals” such as requiring the team to grow product selection by a certain amount. Around five hundred such goals were established inside Amazon and approved by the leadership committee at the end of every calendar year, establishing the most important metrics for each business unit at the company. Teams that owned those goals were required to supply frequent updates on their progress and explanations if they fell behind schedule. It was a crucial way that the S-team managed a sprawling amalgamation of loosely affiliated business units.
I occasionally add a personal note to them.
