text: Enterprise Architecture (EA) has undergone many changes since the IT has found
its way into the world of enterprises. The introduction of Service-Oriented Architecture
(SOA) is such a change with major consequences. The introduction of an SOA increases
the flexibility and thus the productivity of an enterprise architecture, but unfortunately
also its complexity. This makes the transformation of an enterprise architecture
to an SOA-like enterprise architecture to a challenging and risky task. To overcome
the change- and complexity-related problems when introducing SOA, Enterprise Architecture
Management (EAM) systems are required. The approach of this thesis suggests a
method on how to establish Enterprise Architecture Management that is especially
suited for an SOA introduction. This thesis suggests a variant of an EAM system
that is especially suited for the introduction of an SOA. The presented method
on creating such an EAM system includes guidance on how to define a meta model
for Service-Oriented Enterprise Architecture (SOEA), which is harmonized with
the respective enterprise architecture. The SOA introduction is especially supported
by defining SOA quality criteria and corresponding metrics. Some metrics have
to be ascertained by experts. Other metrics have their measuring points within
the SOEA models (instances of the SOEA meta model) and their calculation is automatable.
Creating and maintaining SOEA models as well as applying the automatable metrics
are supported by an eclipse-based tool. As metrics only produce measures that
are hard to interpret, indicators are introduced. They allow interpreting the
measures concerning the quality criteria. With the help of this EAM system, the
transformation of an enterprise to a service-oriented enterprise can be planned
and the level of goal-achievement (SOA-conformance of the EA) can be monitored
steadily. By this, the contribution of this work aims at the reduction of the
risk when introducing an SOA.
