abstract = {Our daily life is characterized by an increasing number of
process supporting IT services. With wireless and mobile
networks, all kinds of devices are connected to the Internet
and constantly access, collect and exchange data with
various IT services to instantly provide information. The
increasing volume and heterogeneity of computer devices
requires changes in the architecture of IT services. At
universities, students, researchers and decentralized
service providers operate and work with such a heterogeneous
and distributed IT service landscape. Existing monolithic
process supporting systems are often highly specialized in
locally defined processes and cover isolated business cases.
If interfaces are available, they often use specific
vocabularies and focus on technical details of the system,
not the supported processes. Users, however, work in
environments spanning across processes and often combine
central and decentral IT services to achieve their goals. As
digital competence is increasing, users seek to
individualize and extend services according to their current
needs. This extended degree of individualization requires a
comprehensive digital service infrastructure. To close the
gap between the user's perception of processes and the
provided interfaces, this thesis proposes and evaluates a
process-aware and service oriented reference architecture.
By gradually hiding the technical complexity of back end
systems, it introduces technical and semantic consistency
across process and system boundaries. Taking into account
the varying organizational, development and governance
processes across back end systems, a web service landscape
is implemented that uses technologies like HTTP, REST and
the OAuth2 workflow to ensure consistency and compatibility
with users' environments. Adaptations of the OAuth2 workflow
allow to cross boundaries of monolithic systems and
integration into the landscape. Tiers of abstraction allow
reuse of services by their technical specification or
semantic modeling. Within various case studies from
different areas of the university, the implementation is
validated in real world scenarios. Semantic consistency
allow users to adapt processes crossing system boundaries to
their own needs. Technical consistency and focus on
standardized technologies does not require technical
knowledge of back end systems and enables individualized
implementations in decentralized computing environments.},
