  1. J-oy J-oy & Software Development

  2. Developmentapproaches • Traditional development problems: • Design many use cases following the same pattern, • Code many use cases following the same pattern, • Keep model up-to-date (design models are usually outdated) • Traditional Model Driven Software Development problems: • Generated code needs to be tailored. Once it happens changes in earlier work products must be manually applied to generated code or a new set of automatically generated pieces of code is created and changes must be manually reapplied to it.
