Two Pizza Teams – Amazon’s organizational model, designed to dramatically reduce the need for communication, enabling growth.
Typically teams have 6‐12 people, including a leader who may act somewhat like a CEO.
Teams are ‘separable’ [organizationally] and ‘single‐threaded’ [work on a single thing].
Teams are responsible for a measurable set of external outcomes, focused on end customers [and immediate consumers].
Team decide internally both what they will work on and how they do the work.
Dependencies between teams are kept to an absolute minimum.
