Introducing Motivations in Design Pattern Representation

Design pattern formalization is aimed at encouraging the use of design patterns during the design phase. In literature many approaches focuses on providing solutions with a graphical notation and complementary text, typically composed by a static and a dynamic definitions. The weak point it the flexibility to customize the generic solution to the specific context of use. This paper proposes a criterion to motivate design pattern selection and reuse. Designer is supported with a fine-grained technique for balancing pattern and problem forces in order to choose among alternative implementations
