Model real-world taxonomies (Vehicle → LandVehicle → Car) and document contracts with UML or lightweight diagrams.
Favor shallow hierarchies that emphasize common abstractions at the top and specialize behavior toward the leaves.
Protect base classes with protected hooks, template methods, and clear documentation about what subclasses may override.
