Map what a shared schema currently supports before proposing
Map what a shared schema currently supports before proposing changes, because schemas embedded in coordination patterns create dependencies that must be managed during transitions.
Why This Is a Principle
Grounded in Schemas as Knowledge Organization Structures (schemas organize knowledge), The behavior of a system arises from its structure… (behavior arises from structure), and An organization's communication structure determines… (communication structure determines system structure). The principle prescribes dependency mapping before schema changes to avoid unintended coordination breakage.
