Nowadays a lack of integration among software services and databases has become a major IT problem in many organizations including banking industries. Service oriented architecture (SOA) is the most recent and comprehensive method among the different methods and technologies proposed for integrity implementation. One of the main reasons for banks' failure in achieving the benefits of SOA is lack of a framework that includes all critical factors in SOA adoption. The aim of this article is to identify and analyze the influential factors (organizational, technical, environmental and human) on SOA adoption in e-banking and providing a comprehensive framework that explains these factors. Such a framework enhances the decision-making and enables banks to achieve the benefits of SOA. In order to gather operational data, questionnaire and interview had been used. The conceptual framework was investigated using Smart PLS and SPSS software. The empirical data investigation and interpretation shows that: organizational, technical, human and environmental factors are crucial for SOA adoption.

One of the common problems of most banks in information technology  in banking area is the lack of software integrity and data banks. For integrating goals, various methods and technologies have been developed. Service oriented architecture (SOA) is among the state of art technologies. The most important goal of employing SOA in e-banking includes enhancing the re-usage level and flexibility of information services, flexibility of information technology in response to continuous business changes, standardization and integration of systems and IT infrastructures. In spite of this, unluckily, most banks experience failure in employing this technology. According to the recent surveys, one of the bank’s failure reasons, is the lack of a comprehensive framework which comprises all effective factors of this architecture. Thus, the goal of this paper is to detect and analyze the effective factors on service oriented architecture in e-banking and providing a comprehensive framework which encompass all factors. This conceptual framework is essential for banks in implementing SOA properly in e-banking area. In this research,  first, in this research  effective factors of using SOA was  detected by a case study,  then most repeated factors were classified. By using statistical software, e.g. SPSS, Excel, statistical tests, e.g. validity and reliability tests  and descriptive  statistical  tests were conducted and the most important factors were detected and a prioritized. As a result of this prioritization, the integration factor of systems had the most and organization features had the least significant effect on using SOA in e-banking.
