  • ISMAEL UTITIAJ thinks this is interesting:

When do patterns come up in the design process, and what role do they play in design? The answer to this question varies with the methodology you’re using—I hope that you do use a methodology—but design patterns are of interest primarily at the implementation level, so they start coming up when you start thinking about implementation. The deeper question then is, when does analysis (which concerns itself with the problem domain) stop and design (which concerns itself with implementation) begin?

Note

Para identificar el rol de los patrones de diseño es importante tener una metodología y reconocer en donde terminar el análisis del problema y en donde inicia el diseño.
