A Design Mechanism is a concrete representation of an Architecture Mechanism. It is refined from an Analysis Mechanism and is itself refined into an Implementation Mechanism as the design becomes more detailed.
Design Mechanisms are represented as concrete design patterns and frameworks (see Using Patterns). Design Mechanisms should still be relatively independent of
implementation but provide enough detailed information for implementation choices to be made and software to be
developed with confidence.
See Example Design Mechanisms for some examples.
