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
