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

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 .
