Two-Pizza Teams
“No team should be larger than what two pizzas can feed.” This principle, introduced by Jeff Bezos at Amazon, limits teams to roughly 5 to 10 people with single-threaded ownership over one product or service, end-to-end from development through operations.
The rationale echoes Brooks’s Law: smaller teams have fewer communication channels, faster decisions, and stronger accountability. Bezos explicitly opposed increased inter-team communication, favoring decentralized, independent teams. Two-pizza teams own their services, deploy independently, and are measured on customer outcomes rather than component-level metrics.
