This article summarizes the results of 25 expert interviews, regarding the value potential and
challenges of the Service-oriented Architecture (SoA) paradigm for users and software vendors.
On the user side, the SoA value potential most often mentioned by experts was agility, followed by
process optimization. Cost reduction, through a more efficient development, or consolidation of
redundant IS landscapes are also seen as a value potential. In contrast to the literature, reuse of
services seems not that significant and is highly debated among the experts. In order to realize the
value potentials, users have to overcome certain challenges. Here, the experts mention the financing
of the investments, the setting up of a proper governance and the creation of a common understanding
of the SoA paradigm as biggest hurdles.
For the software vendors, experts mention that SoA-based solutions create new market opportunities
as lock-in-effects are lowered and offerings can be easier enhanced by third-party services. Regarding
cost, there is potential to harmonize existing product portfolios or integrate acquisitions more easily.
Development cost reduction is less evident at the current stage of adoption. It is assumed that lower
lock-in effects also lead to increased competition, which could become a major challenge especially
for established vendors.
