Prerequisites for successful Implementation of Service-Oriented Architecture

Service-oriented architecture (SOA) is a set of principles for designing extensible, federated and interoperable services, and it represents a new evolutional spiral in the program-applications development and in the evolution of the information systems concept. SOA represents an extraordinary challenge at scientific, practical and economical level. That is a reason why SOA represents the topic of many different researches. Some researches have shown that implementation of SOA is often not successful (e.g. one of four SOA implementation have failed). One of the reasons for this is the fact that organizations have not adopted and fulfilled some basic SOA prerequisites. The SOA prerequisites are not clearly defined. They are some researches on this topic but they are mostly focused on technical aspects of SOA implementation. This article analyses necessary set of prerequisites which should be fulfil by organization attempting to implement SOA. Since SOA implementation requests significant organizational changes such set of prerequisites should comprise not only from technical prerequisites but should take into account data architecture, system integration and compatibility, security and legislative requirements, business requirements and organizational prerequisites. This set of prerequisites can be defined as a Service-Oriented Architecture Maturity Model and used to evaluate the possibility for successful utilization of SOA in specific organization.
