4. Telecommunications Services Issues
Long concept-to-market time.
Large and complex systems constituted of
services distributed over technological spaces and
vendor domains.
Numerous interactions between services.
Lack of computer-supported tools for service
designers.

26. Conclusion
Benefits of a Model-driven approach
• Rapid tool prototyping
• Independence from the implementation platform
• Iterating definition of the Domain Definition Meta-
model
• Tool connection through interchangeable models
But … limitations
• Model-driven tools still in infancy phase
page 25 EUNICE 2009 A Model-driven Approach

27. Conclusion
Reduced concept-to-market time
• Improved productivity of service designers through
use of a specific modeling language.
Bridged gaps between technological spaces and
vendor domains
• Use of platform independent models.
