change-management-comprehensive-coverage

Status: OUT

Composition-based OO design provides comprehensive change management: coupling management handles both boundary adaptation (Adapter/Facade via DIP) and behavioral decoupling (Command/Observer/Mediator/Chain), while OCP with Visitor's axis inversion handles extensibility along both the type and operation dimensions — together covering isolation from change AND accommodation of change.

Justifications

Coupling management isolates existing code from change; OCP+Visitor accommodate new requirements; together they span the full change management space unless DIP is over-applied

Depends on (SL): coupling-management-covers-boundary-and-behavioral, ocp-composition-with-principled-escape

Unless: dip-overgeneralization-pitfall
