Process-driven service-oriented architectures
(SOA) need to cope with constant changing requirements
of various compliance requirements, such as quality of service
(QoS) constraints within service level agreements (SLA). To
the best of our knowledge, only little evidence is available if
and in how far process-driven SOAs deal with the evolution
of the requirements. In this work, we evaluate an incremental
and model-driven development approach on the evolution of
the requirements and the domain model in the context of
an industrial case study. The case study focuses on advanced
telecom services that need to be compliant to QoS constraints.
This paper answers questions about the applicability of the
incremental development approach, the impact of requirement
changes, possible drawbacks of using a non-incremental
development approach, and general recommendations based
on the findings. Our results provide guidelines for dealing with
the evolution of model-driven service-oriented systems.
