From Implementation of Service-Oriented Architecture to Organizational Agility by System Dynamics Modeling Approach



: Service-oriented architecture is a kind of organizational architecture which uses services with the aim of simplification, and implementation of integration activities. Companies to survive in the dynamic environment need to strengthen their organizations through information systems. Service-oriented architecture is a way for the integration and effectiveness of the use of information systems and achieve organizational agility. In this paper after reviewing the literature and previous researches, variables that affect the implementation of service-oriented architecture and organizational agility are extracted. Afterwards, system dynamics approach was used for designing a model which indicates dynamics of service-oriented architecture and their contribution to organizational agility. The validity of the model was confirmed by evaluation methods in dynamics model by using VENSIM software. Finally, based on different scenarios of proposed variables, various scenarios designed and their implementations were simulated. The results showed increased investing to enhance system security, increased rate of return on investment influence on the implementation of service-oriented architecture and increasing the level of implementation of service-oriented architecture by dynamic mechanism increased accountability and organizational agility.
