Abstract
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.
Highlights
Increasing growth changes in organizations, makes organizations get more complex continuously
It is based on technology and its impact on both business and technology domain is obvious[3].Service oriented architecture (SOA) is a framework for integrating service-oriented business processes and supports them by standard and secure components which are called service are reusable and loose coupling to cover all business process changes[4]
Assign the weights of indices and determine fuzzy rules, our expert community includes persons who are expert on information technology (IT) and service-oriented architecture field.Based on assumptions and by considering fuzzy approach, a questionnaire has been designed in one section and distributed among experts
Summary
Increasing growth changes in organizations, makes organizations get more complex continuously. Without using of information technology, many problems occur in order to achieve the organization's goals Planning to achieve these organizational objectives needs a real understanding of the current situation which is obtained by readiness assessment measures; on the other hand in transferring processes and data changes to its applications and related issues, we should act flexible. Organization can implement SOA rightly, so all processes and services are quite flexible and quickly. It can be created and configured based on the business requirements but no needing the professional or technical personnel. There is no specific definition for service-oriented architecture (SOA), but most agree that this architecture is related to the lower layers of organization. Anjariny et al proposed a model for business intelligent systems readiness assessment model [19]
