properly, MBT will become even more effective technology within the telecommunication
domain.
Initial expectations on MBT were that modeling is difficult and requires a lot of expertise
and competence. Our experiences indicate the opposite. Modeling as a competence seems
to be fairly easy to learn. At the same time, modeling helps gain and retain an overview of
the system behavior much easier than using programming and scripting languages.
Automated test generation is clearly significantly different in comparison to manual test
scripting. In test generation, the emphasis is on the design phase instead of the
