The document summarizes key concepts and practices related to scaling agile development from the individual level to large organizations. It covers agile principles, techniques for individuals and teams like test-driven development and continuous integration, architectural approaches like microservices and service-oriented architecture, and organizational considerations like DevOps. The goal is to help organizations apply agile principles at different levels of scale.

5. We are uncovering better ways of developing software by doing it and
helping others do it. Through this work we have come to value:
Individuals and Interactions over processes and tools
Working Software over comprehensive documentation
Customer Collaboration over contract negotiation
Responding to Change over following a plan
That is, while there is value in the items on
the right, we value the items on the left more.

29. Conway’s Law
“Any organization that designs a system… will produce
a design whose structure is a copy of the organization’s
communication structure.”
시스템을 만드는 회사의 조직은 마치 그 조직의
커뮤니케이션 구조를 그대로 가져다 둔 듯한 구조로
제품을 만들게 된다.
— Melvin Conway, 1967
