An Assessment Model for the State of Organizational Readiness Inservice Oriented architecture Implementation Based on Fuzzy Logic

Growth changes in organizations and on the other hand strong need to utilization of information and communication technology possibly implied applying changes in organization in accordance with changes in functionality. What's more, information technology structure, hardware, software and information infrastructure have to be synchronized. One of the most important approaches leading to this goal are service oriented architecture.Service oriented architecture (SOA) is a style of information systems architecture supporting loose coupling of services for flexibility and interoperability of systems and is independent of the technology. The most important achievement of creating service oriented architecture is the need for increasing flexibility, speed and agility. Consequently, it changes in the structure of its organization. According to broad scope of enterprise architecture projects, it is necessary before implementation and the related major cost, organization would be notified of its readiness to get right decisions, develop appropriate strategies and adopt new approach.In this paper, we propose a model for evaluating organizational readiness in order to implement SOA with the use of Mamdani fuzzy logic. According to the results of this assessment method, we can decide more precisely whether an organization is ready to adopt SOA or not.By using this assessment model, organizations can realize their strengths and weaknesses identify their improvement areas and thus increase their readiness. Consequently this model is tested by means of a case study in Tehran municipality ICT organization.
