Summary


When moving from analysis to design, several decisions has to be made. These decisions should be documented and it should be possible to view the impact of such decisions. A way to achieve this is the Paste As functionality that produces links that could be traversed in order to do "what if" analysis or to do consistency checks between requirements and design.

When we start to design from our analysis models, several possible SDL mappings exist for entities in the object model and the use cases. The important decisions that have to be made concern issues like reuse and determining if objects should have autonomous behavior or not (active/passive objects).
