Minimize import requirements.

• Make it easy to instantiate and support the component.
• Use standardized interfaces on helpers.
• Use stateless servers as helpers
• Use service-based not object-based specifications.
• Impose weaker constraints on helpers.
• Have component give up control over certain functions.
• Allow helpers to dynamically change (don't hard-wire)
• Use the most abstract component interface specification (e.g., base class) as a helper (pointers to helper in C++).
• Use relays and name servers (polymorphism via dynamic means). Relays accept generic service requests and forward them to appopriate components, while name servers tell clients about components that can perform services.
• Strategies differ according to actual mechanisms used for dynamic connections (procedure calls, RPC (Remote procedure calls), message sends, events, pipes, etc.). But rely on the weakest sufficient protocol.
