  12. 12. CONCLUSIONS The approach assures that validation tasks are performed continuously along the modeling process. It allows for validating:  the final software solution according to the initial expressed requirements;  the B-Type sequence diagrams according to A-Type sequence diagrams;  the logical diagram by traversing it with B-Type sequence diagrams. The presented approach compels the designers and developers to provide a set of models that allow the requirements to be sustainably specified; 12 © 2010-2013 ISOFIN
  13. 13. CONCLUSIONS Each created model in the V+V process takes knowledge from the previously created model as input. Since they are created in succession, the time required to derive a given model is smaller than the previous one. The V+V process is able to conduct reviews regarding architectural decisions; Traceability between the models is integrated in our V+V process thus, any change made to those domain-specific needs is reflected in the logical architectural model . 13 © 2010-2013 ISOFIN
