OCE.7:2 - Problem
One-sided decisions externalize burden. A modular product can be assigned to nominally independent teams that still share one test rig, safety decision, data source, or specialist. A reorganized stream can inherit a tightly coupled product that requires constant cross-stream integration. A service boundary can be redrawn without the provider authority, observability, or recovery conditions needed to operate it.
Mirroring language hides these facts when it treats similarity as adequacy or inevitability. Practitioners can also mistake an influence on the design, expressed in a chart, architecture description, or decision record, for the Work that realizes it. They then cannot tell what relation created the pressure, which System performed the Work, or which side should change.
