In adoption process of Service Oriented Architecture (SOA), the legacy systems of a company can not be neglected. The reason is the legacy systems have been deployed in the past and have been running critical business processes within an enterprise in its current IT architecture. However not all migration process of legacy systems to SOA has been successfull. Highlighting the right factors to reach legacy systems migration success in a specific company is the key value. The main adopted research method in this study has been interviewed for different companies with different enterprises including bank, furniture, engineering and airline companies in Europe. Through separate interviews, critical success factors of migrating legacy systems into SOA have been collected and identified in each case company. Finally collected results are analyzed and presented as the recognized factors affecting successful migration oflegacy assets into SOA from business and technical perspectives.

Cloud computing has emerged as a powerful new technology. The processing and computation power embedded in the cloud technology is not only flexible but also infinitely scalable and cost effective. Service oriented architecture (SOA) is a perfect stage for cloud computing. SOA has allowed customers and organizations to achieve cloud computing and reap its benefits that would not have been possible through any other architecture. This paper discusses the concept and importance of service oriented cloud computing by highlighting possible architectures, their benefits and critical success factors.

Systematic Synthesis

Information Technology (IT) projects are more and more aligned with business goals. Service Oriented Architecture (SOA) was introduced to achieve this, align business with IT, and increase IT flexibility, reuse of services in more manageable way. Unfortunately, healthcare organisations that have adopted SOA have yet to benefit from their investment. Industry analysts and academics agree that SOA Governance is a critical success factors for SOA projects. Addressing the substantial research gap, this chapter investigates longstanding challenges and proposes a SOA Governance framework as a way to improve IT/SOA success and guide the alignment of IT and business. The authors present a systematic synthesis of the latest research findings and professional experience on SOA Governance considerations for successful IT projects.

Reverse engineering techniques have become very important within the maintenance process providing several benefits. They retrieve abstract representations that not only facilitate the comprehension of legacy systems but also refactor these representations. Business process archaeology has emerged as a set of techniques and tools to recover business processes from source code and to preserve the existing business functions and rules buried in legacy source code. This chapter presents a reverse engineering process and a tool to retrieve services from running databases. These services are further reused in composing business processes with respect to Service-Oriented Architecture, a new architectural style that promotes agility.

Architecture Modeling

This chapter focuses on the identification and specification of services based on prior modeled business processes and legacy systems. The resulting service interfaces and service components formalized by using the Service oriented architecture Modeling Language (SoaML) describe the integration of legacy systems into a service-oriented application landscape. The legacy systems provide services for integration purposes and represent the implementations of service components. Additionally, the resulting architecture allows functionality of legacy systems to be replaced with functionality provided by external cloud services. According to model-driven development concepts, the formalized service interfaces and service components as part of the service designs can be used to automatically derive service interface descriptions using the Web Services Description Language (WSDL). These descriptions enable the technical integration of legacy systems. If necessary, service implementations based on the Service Component Architecture (SCA) and the Business Process Execution Language (BPEL) can be generated.

Service Oriented Architecture (SOA) Governance is a critical factor for the success of SOA implementations, yet a detailed SOA Governance framework is lacking. The paper reintroduces a conceptual SOA Governance framework in a healthcare setting. The proposed framework is based on a rigorous literature review and consist of nine governance elements that should be considered during the SOA practice. The identification and conceptualisation of the elements are grounded in the normative literature. Moreover, the authors propose a unique formulation combining nine elements of SOA Governance with SOA Critical Success Factors (CSFs) and Healthcare Information Systems (HIS) challenges. This proposal aims to pinpoint attributes and guidelines for each element, required to successfully govern SOA and tackle longstanding HIS challenges. The framework is intended to be used as a decision supporting tool for SOA governance in a healthcare setting.

Commercial Organizations

Currently, government and commercial organizations are increasingly dependent on the use of various information systems. Investments in information systems fi their place in enterprises of various sizes, from small to large. The main goal, which forces enterprises to imple ment information systems, is the need to obtain centralized access to information and facilitate the procedure for its receipt, storage and processing in order to increase productivity and increase the efficiency of production activities. Currently, information systems are a tool for standardizing business processes and offer a variety of functionalities based on best prac­tices. At the same time, the implementation of the system is a difficult task (there is a very high percentage of unsuccessful projects), requiring great efforts, careful reflection and good planning, as well as a detailed analysis of the factors that are critical for the successful im­plementation of the system. Right now, the urgent need for finding new tools and opportunities to increase the number of successful projects. The article is devoted to critical factors affecting projects for the implementation of information systems in enterprises. The scientific works of domestic and foreign scientists and practitioners are analyzed and reviewed in order to identify factors that are called critical success factors that directly affect such projects in order to determine which critical factors were empirically recognized as “critical”. To evaluate each factor and the relationship between them, the author uses statistical analysis. The study also uses both quantitative and qualitative analysis of data obtained from scientific papers. The data collected were analyzed and 10 key success factors identified. Critical success factors are an effective and important tool for achieving the goals of projects for the implementation of information systems in enterprises, which will contribute to the correct decision-making and improve the effectiveness of projects and, as a result, the achievement of strategic goals that bring long-term benefits to the enterprise.

Development Paradigm

Many vendors have acclaimed Service Oriented Architecture (SOA) as a better way to design and build enterprise-wide information systems (EWIS). While these claims may be true in the private sector, there is scant evidence in the literature for the same success in the public sector. The adoption of Enterprise-wide SOA (ESOA) as the dominant development paradigm within an organization often requires significant organizational changes, which are difficult to achieve in the public sector, with its strict hierarchies and departmental independence. Although many government departments are beginning to adopt this new paradigm, the literature does not provide a suitable ESOA implementation readiness framework for use in the public sector. This research proposes a framework based on Critical Success Factors (CSFs) and a CSF scorecard to evaluate an organisation’s ESOA implementation readiness. The framework and scorecard were tested in a test case in the Malaysian government, and the results validate the accuracy and usefulness of both the CSF Framework and the CSF Scorecard.

PurposeWicked problems require collaborative innovation approaches. Understanding the problem from the users' perspective is essential. Based on a complex and ill-defined case, the purpose of the current paper is to identify some critical success factors in defining the “right problem” to be addressed.Design/methodology/approachAn empirical research study was carried out in a low-density municipality (case study). Extensive data were collected from official databases, individual semi-structured interviews and a focus group involving citizens, local authorities, civil servants and other relevant stakeholders.FindingsAs defined by the central government, the problem to be addressed by the research team was to identify which justice services should be made available locally to a small- and low-density community. The problem was initially formulated using top-down reasoning. In-depth contact with citizens and key local players revealed that the lack of justice services was not “the issue” for that community. Mobility constraints and the shortage of economic opportunities had a considerable impact on the lack of demand for justice services. By using a bottom-up perspective, it was possible to reframe the problem to be addressed and suggest a new concept to be tested at later stages.Social implicationsThe approach followed called attention to the importance of listening to citizens and local organisations with a profound knowledge of the territory to effectively identify and circumscribe a local problem in the justice field.Originality/valueThe paper highlights the limitations of traditional rational problem-solving approaches and contributes to expanding the voice-of-the-customer principle showing how it can lead to a substantially new definition of the problem to be addressed.
