Depending on the tasks, they will build many small entrepreneurial teams. The size of a team is generally 4-14 people, including several engineers, a product manager and a designer. The team leader has full say in the business he is responsible for, and the team members report directly to him.

This is Amazon's "two pizza rule", which means that two pizzas can solve the working lunch of a team. In other words, the team is small enough.

Therefore, each small team at Amazon is very active, with high staff participation, better organizational synergy and cultural identity than the general large team organization, so naturally the efficiency and quality of work are guaranteed. In addition, if a small team fails, it will not affect other teams.
