Preface
Service-oriented architecture (SOA) is one of the technologies in the area of infor-
mation systems’ design and architecture in the recent technology world. SOA adop-
tion is known as an evolutionary process, instead of revolutionary one. In this
process, an application is developed in a long period of time which will be improved
gradually. Since there is a limited number of researches that focus on the effects of
SOA adoption in an organization, this study investigated the significant factors
which affected SOA and have been more discussible in the last 5 years based on
previous studies such as governance, strategy, complexity, return on investment
(ROI), business and IT alignment, culture and communication, costs, and security.
Since most of the researches focus on qualitative analysis for SOA adoption, a need
for empirical research was felt. So, this study conducted a quantitative analysis to
investigate the influential factors for adopting SOA. In addition, an SOA adoption
framework was proposed to measure the effect of factors on SOA adoption and the
performance of organizations. Based on the proposed framework, an online ques-
tionnaire was created and distributed among SOA experts through LinkedIn (the
largest social networking website for people in professional occupations) to collect
data about the influence of SOA adoption on organizations. Subsequently, this study
has made recommendations for improving the organizations planning to adopt SOA
or in the way of adopting SOA to promote the performance of their organizations.
On the other hand, the outcomes of this study may pave the way to form the basic
knowledge in the domain of organizational and technological SOA adoption and
trigger further research in the field.
