This document discusses the relationship between bureaucracy, civilizations, and agile practices using metaphors of barbarians and Roman empires. It argues that bureaucracy serves an exploitation purpose of extracting value through rules and control, while agile practices and small groups resemble barbarian villages that focus on exploration, creativity, and bottom-up problem solving. Over time, barbarian villages are able to turn Roman empires agile by speeding up explore-exploit cycles through technology and mobility. The key is for organizations to benefit from and encapsulate the exploration of agile "barbarian villages" without becoming overly bureaucratic.
