Service Oriented Architecture Adoption Research Articles

Analisis Tingkat Kematangan Adopsi Service Oriented Architecture Menggunakan ISO/IEC 16680 (OSIMM)

Enterprise application integration makes data sharing easier, efficient and provides flexibility for organizations to seize opportunities and respond to stakeholder needs. Faculty of Mathematics and Natural Sciences (FMIPA) Tanjungpura University is an organization that wants to apply information technology effectively to support its business processes. Currently the application at FMIPA is built with different platforms and databases so that it cannot be integrated to share data between parts of the organization. FMIPA intends to build a service-oriented technology architecture to support the realization of organizational goals. SOA (Service Oriented Architecture) can be used as a framework for enterprise application integration. SOA adoption is often not as expected because organizations do not plan their processes comprehensively. It is necessary to measure the maturity level of the organization's SOA adoption so that the current state of the organization's SOA and future expectations can be found. ISO/IEC 16680 (OSIMM) is a method for measuring the SOA maturity level with 7 levels of maturity and 7 dimensions. To expedite the SOA adoption process in FMIPA, SOA maturity level was measured using ISO/IEC 16680. Based on measurements of the seven dimensions of SOA at ISO/IEC 16680, it was found that the current level of SOA adoption maturity (As-Is) at FMIPA Untan was at the level one (Silo), while the expected maturity level (To-Be) is level four (Service). Gap analysis then carried out related to the gap in maturity levels, and is followed by making recommendations dan roadmap for SOA adoption.

Service-Oriented Architecture: A Review of State-of-the-Art Literature From an Organizational Perspective

Over the past two decades, the topic of service-oriented architecture (SOA) has attracted considerable attention among researchers and practitioners. Despite a lot of efforts to study it from different points of view (mostly from a technological perspective), little is done to develop our understanding of SOA from an organizational perspective. Therefore, this study aims at reviewing the literature on SOA from an organizational point of view. To this end, 65 journal papers (published between 2005 and 2020) were selected from different electronic databases for study. After a careful review of selected papers, four distinct categories of research themes were identified: SOA adoption, implementation, governance, and organizational impacts and applications. Moreover, major factors influencing SOA adoption as well as potential areas of impact of SOA in firms were determined.

A methodical framework for service oriented architecture adoption: Guidelines, building blocks, and method fragments

Rapidly-changing business requirements expect high business process flexibility that can be achieved using service oriented architecture (SOA). This requires enterprises to adopt SOA and assess their SOA adoption maturity to achieve continuous improvement. SOA realization demands service development with varying levels of granularity. The research aims to develop a methodical framework for SOA realization based on Welke's SOA maturity model, a model that assumes a methodology dimension. The framework is concerned with formalizing knowledge on how to identify and shape the main building blocks of a method at each maturity level. The research applies the principles of design science research and method engineering to develop a methodical framework for SOA realization. The research identifies the gaps in SOA realization methods and illustrates how a methodical framework based on a maturity model facilitates the SOA adoption process. The evaluation results revealed that the framework would help enterprises to select method fragments required at each maturity level to accomplish business excellence. The implications of this research are twofold: from a theoretical perspective, the researchers or practitioners can use the results for further study. From a practical standpoint, enterprises can use the methodical guidelines to assess their current maturity level and select and implement the required method fragments from the method base provided in the proposed framework.

AN EXPLORATORY STUDY FOR INVESTIGATING THE ISSUES AND CURRENT PRACTICES OF SERVICE-ORIENTED ARCHITECTURE ADOPTION

Service-Oriented Architecture (SOA) is an approach that can be used to integrate different services across the operating system, platform, language, and network which offers some benefits. However, many organizations failed to fully utilize the SOA because the adoption processes are still immature. Therefore, an exploratory study was conducted which aims to investigate the current issues and practices of SOA adoption, the use of maturity levels for assessing the SOA adoption, and the importance of IT and business benefits in the SOA adoption. Thus, the Grounded Theory approach was adapted in the study which involved seven (7) software development companies in Malaysia. In this study, fourteen (14) SOA practitioners with at least three years of experience in the SOA development were interviewed. The collected data was analyzed through three main coding stages which are open, axial and selective coding. The theory emerged from this study reveals the SOA adoption issues, current practices, maturity levels, IT and Business benefits. The study managed to identify five main issues in SOA adoption which are knowledge, infrastructures, costing, readiness, and documentation issues. The study also portrays five practices related to technology, framework, platform, standard, and tools. On the other hand, the results show five IT and business benefits consecutively. The findings from the study have lead to the theories formulation on the SOA adoption which may assist researchers and SOA assessors to continuously improve the quality and maturity of SOA adoption in the future.

SOA Adoption Factors in E-Banking: An Empirical Analysis from the Practical Perspective

Nowadays a lack of integration among software services and databases has become a major IT problem in many organizations including banking industries. Service oriented architecture (SOA) is the most recent and comprehensive method among the different methods and technologies proposed for integrity implementation. One of the main reasons for banks' failure in achieving the benefits of SOA is lack of a framework that includes all critical factors in SOA adoption. The aim of this article is to identify and analyze the influential factors (organizational, technical, environmental and human) on SOA adoption in e-banking and providing a comprehensive framework that explains these factors. Such a framework enhances the decision-making and enables banks to achieve the benefits of SOA. In order to gather operational data, questionnaire and interview had been used. The conceptual framework was investigated using Smart PLS and SPSS software. The empirical data investigation and interpretation shows that: organizational, technical, human and environmental factors are crucial for SOA adoption.

Service Oriented Architecture Adoption: A Systematic Review

Service Oriented Architecture (SOA) has appeared as an absorbing architectural approach that empowers the available systems to reveal their performance in the act of services without creating important changes to the systems. This approach, due to its flexibility of adoption, has been widely appreciated by the businesses. Though there are many studies that depict successful factors of SOA, a few minor cases of failure have also been reported in the literature. In spite of the availability of rich material on SOA, there is no systematic literature review on the influential aspect of SOA adoption factors. Thus, this paper presents a systematic literature review of existing studies (from 2009 to 2015) related to the SOA adoption and its success and failure. The central purpose of the study is to focus on the existing issues and share the findings with researchers. Moreover, the findings of this paper would help the IT experts in organizations focus on the most important factors highlighted in this study, so they could decide whether it is advisable to adopt SOA in their context or not.

A method engineering perspective for service-oriented system engineering

Purpose – The purpose of this paper is to consider the method engineering perspective for service-oriented system engineering (SOSE). A number of SOSE methods have been proposed in both academia and industry. Given this, many intuitive, common questions arise. To answer these questions, many comparison frameworks have been developed. Each of which has considered certain methodological perspectives. However, less attention has been given to the method engineering (ME) perspective. The authors argue that this perspective would answer the question “what ME to apply in order to produce SOSE methods that themselves produce quality services at different levels of abstraction and SBAs”. This research question is further decomposed into other questions; the main one is “whether the existing ME do apply to service orientation”. Answering such a question would lead to either developing SOSE methods by using the existing ME or developing a new ME or framework for the specifics of SOSE. Design/methodology/approach – This work first provides a literature review on ME approaches and techniques; then, it compares a sample of existing SOSE methods with respect to their ME within a comparison framework that comprises a set of relevant properties of a solution that would be provided by an SOSE method, namely, service-oriented architecture (SOA) adoption, quality of services and ME; and finally, it discusses the applicability of the existing ME to SOSE. Findings – Strengths and weaknesses of the existing methods with respect to the aforementioned criteria, in addition to SOSE methodology open issues, were identified. The comparison has shown that while the existing SOSE methods have proved their success in a specific task, they still present some weaknesses. Therefore, it is better to benefit from the advantages of the existing ME techniques, notable method fragments, even if they need some alteration. Research limitations/implications – While this work has many open issues related to SOSE methods with respect to ME, it could be further developed in many directions by exploring the open issues. For instance, the generation of a new ME technique and application of this new ME technique to the existing SOSE methods to see to what extent the existing methods may be situational. Practical implications – This work has practical implications, as it provides a better understanding of different views of SOSE methods, and assists the method engineers in deciding which ME technique is most suitable to their situation. Social implications – The produced artifact provides a research roadmap toward SOSE ME. Originality/value – None of the existing comparison frameworks for SOSE methods has considered the criteria such as SOA adoption and ME techniques. Indeed, ME techniques and approaches would allow better reuse of the existing proven fragments of methods.

A Method for SOA Maturity Assessment and Improvement

This work presents a model for corporate maturity assessment to evaluate and improve Service Oriented Architecture (SOA) adoption. The model is designed by parameterization of a best practices knowledge base in survey´s questions to support evaluation, planning and monitoring the evolution of organizational maturity in SOA. The proposed model is divided into several domains and is carried out inside each domain qualitatively based on quantitative methods. Its concept significantly extends the model The Open Group Service Integration Maturity Model (OSIMM), by allowing the direct monitoring of all strategic goals and their fundamental practices (service lifecycle and design principles). The application of the model is supported by a software system that provides electronic questionnaires, described in a knowledge base and performs classification of maturity through a heuristic method itself. The analysis results provide information to managers, consultants and IT professionals, to perform systematically adjustments of SOA adoption and generate proposed tasks to obtain a desired maturity stage. Therefore, this model proposes activities to stabilize a current state in SOA adoption, or even actions for achieving a higher level of SOA maturity through reference roadmaps.

A Framework for Service-oriented Architecture Adoption in e-Banking: the Case of Banks from a Transition and a Developed Economy

In addressing integration issues, service-oriented architecture (SOA) has emerged and been adopted by banks, but many of them have failed to achieve significant SOA benefits. An important reason for this failure is attributed to the absence of a methodological framework that explains factors influencing SOA adoption in e-banking. In addition to this, the normative literature reports that differences may exist between organizations from developed and transition economies when they adopt integration technologies. Thus, the aim of this paper is to (a) propose a methodological framework for SOA adoption, (b) test it through case studies conducted in a developed and a transition economy, and (c) investigate differences and similarities among these two types of economies. The findings verify our framework and suggest some additions to it as there are new factors that were observed during the case studies like SOA governance. Our study also reveals similarities and differences, like the level of attention between case organizations from a developed and transition economy. This paper extends the body of knowledge and allows us to better understand the adoption practices of the organizations from developed and transition economies. The paper also provides new insights related to factors affecting SOA adoption in e-banking.

A systematic survey of service identification methods

One of the major challenges for the adoption of the service-oriented architecture (SOA) is the service identification phase that aims to determine which services are appropriate to be implemented. In the last decade, several service identification methods (SIMs) were proposed. However, the service identification phase still remains a challenge to organizations due to the lack of systematic methods and comprehensive approaches that support the examination of the businesses from multiple perspectives and consider service quality attributes. This work aims to provide an overview of existing SIMs by detailing which service's perspectives, stated as relevant by the industry, are addressed by the SIMs and also by synthesizing the identification techniques used by them. We have performed a systematic survey over publications about SIMs from 2002 to June 2013, and 105 studies were selected. A detailed investigation on the analyzed SIMs revealed that the identification techniques applied by them have a correlation on how they address many of the service's perspectives. In addition, they are supporting the SOA adoption by handling many perspectives of the OASIS' reference architecture for SOA. However, most of them do not explicitly address service quality attributes and few studies support the evaluation of both. Therefore, future research should follow the direction toward hybrid methods with mechanisms to elicit business and service's quality attributes.

SOA adoption in e-banking

Purpose – The purpose of this paper is to identify and analyze influential factors of service-oriented architecture (SOA) adoption in e-banking and to provide a methodological framework that explains these factors. One of the main reasons why banks fail to achieve the benefits from SOA adoption is attributed to the lack of a framework that takes multiple perspectives of crucial factors into account. For this reason, the absence of such a methodological framework forms an important research problem that requires deeper investigation. In addressing this issue the paper proposes a framework that improves the decision-making process and helps banks raising SOA adoption benefits. Design/methodology/approach – The paper is based on a critical review and analysis of the normative literature, the development of a conceptual framework for SOA adoption in e-banking and the examination of this through a case study in a real environment. Various data collection methods such as personal interview, archival records, documentation and observation are used. Empirical data are triangulated and then analyzed to draw empirical conclusions. Findings – Several factors and classifications of factors related to SOA adoption are not similar among researchers and there is no completed study on analyzing the influential factors related to SOA adoption in e-banking. The findings provide new insights related to influential factors of SOA adoption in e-banking and extend the body of knowledge. The findings show that the proposed framework can improve the decision-making process and help banks to increase the SOA adoption benefits in an e-banking environment. Originality/value – An earlier version of the paper was presented at the European, Mediterranean and Middle Eastern Conference on Information Systems 2012 and has been selected for publishing in the Journal of Enterprise Information Management. This paper adds a new dimension to existing SOA frameworks by investigating influential factors of SOA adoption in e-banking where limited research has been done, facilitates banks in making robust decisions for SOA adoption in e-banking and enriches the bibliography related to SOA adoption in e-banking.

Factors affecting the organizational adoption of service-oriented architecture (SOA)

Service-oriented architecture (SOA) takes an architectural approach to designing and implementing IT solutions. Although it is fast emerging as one of the major architectural styles to execute enterprise architecture management, academic empirical research on SOA adoption is scarce, with most studies focusing on qualitative analysis. This study investigates organizational SOA adoption in South Africa and combines the perspectives of the diffusion of innovations theory and the technology-organization-environment framework into one comprehensive model of SOA adoption. In order to validate the research instrument and to gauge the state of SOA adoption, an online survey was conducted among enterprise architects in South African organizations. The survey provides insights in the perceived risks, obstacles but also expected benefits of SOA adoption. The results also highlight a number of factors significantly influencing SOA adoption in South Africa. Use of multiple standards and platforms, compatibility, top management support, good governance and strategy, adequate human and financial resources, vendor support for integration and development tools are all significant factors for a fruitful SOA implementation. Finally, all of the above adoption factors as well as cost and complexity were also found to correlate significantly with the degree of success of the SOA implementation as perceived by the IT or EA department.

Business value assessment of services re-use on SOA using appropriate methodologies, metrics and models

The main advantage of service re-use for the companies includes retaining a competitive advantage. The expectation of greater service re-use is one of the core benefits of a service-oriented architecture (SOA). Besides the top drivers for SOA adoption include business flexibility, simplification and speed of integration. So, in order to maximise the intended benefits of SOA implementation, organisations need to develop a well-articulated SOA quality strategy to promote trust and re-use. However, the shift to this strategy does not come easy and cheap. Building an effective SOA platform requires tight integration between new and existing product categories, and it may require large investments. The same applies for developing re-usable services. For this reason, conventional investment valuation methods need to be combined with other modern techniques to reflect service re-use’s long-term strategic investment nature, the inherent uncertainty and the managerial discretion. Many value-based analytical methodologies have started to be developed. Thus, in this paper, we explain the role of SOA for services re-use and focus on the methodologies, metrics and models that are able to measure the business value of service re-use.

A Roadmap towards Service-Oriented Enterprise

In the current economic context, enterprises are struggling to obtain competitive advantages on the market, by exploiting the opportunities offered by information technology. The research in this paper aims to encourage the use of modern approaches in order to increase enterprise agility, through the transition to Service-Oriented Enterprise (SOE). The proposed solution is based on reaching a superior level of maturity of Service-Oriented Architecture (SOA) within the organization. SOE integrates the latest technologies with service-oriented business processes within an approach which requires the creation of an agile architecture and also major changes at organizational level. Structured in two main parts, the paper first highlights the SOA maturity levels in organization according to several factors, as well as the knowledge of the impact and the changes arising from SOA adoption. In addition, an architectural model for service-oriented enterprise is proposed, based on up-to-date technologies like SOA, Cloud Computing, Business Process Management and Case Management. This model is intended to facilitate the interoperability between business partners as well as the alignment of information technology strategy and business strategy, and ultimately to increase enterprise agility.

SOA adoption in higher education: a practical guide to service- oriented virtual learning environment

The adoption of Service-Oriented Architecture (SOA) in higher education helps solve the adaptability problems by reducing the complexity of integration of new systems, by reusing services, and increasing the agility. Even more, using shared services and Cloud Computing solutions helps universities to create a collaborative and open environment, with low costs and efficient service management. This paper proposes a SOA adoption solution for universities with the aim of creating an environment where learners access more easily the digital information in order to support their lifelong education and career goals. Also, the paper analyses the integration of education systems and standards with SOA, as well as the creation of new educational environments. The solution helps understand the way universities can solve the complex and growing demands of the educational system with reduces investments.

PROJECT ORIENTATION: A PROPOSAL TO DEVELOP A SERVICEORIENTED ARCHITECTURE

A service-oriented architecture (SOA) is occasionally seen as a complex and undefeatable challenge (Serman, 2007). This feeling is motivated by the lack of attention from practitioners and from the academy on the means for its construction. The work aims to bring the portfolio management of IT projects as an option to guide the SOA development. A review of the literature on SOA was carried out, including case studies on the SOA adoption. A case study was also done, which analyzed some projects of a particular organization, focusing on the evolution of its services architecture. The results show a gradual development of SOA in the case studied based on projects execution and sequencing. It concludes with a proposal of a process for building SOA as well as suggestions and limitations for future research.

Critical Success Factors in SOA Implementation: An Exploratory Study

In recent years, the movement to establish a concept of service science has consolidated itself as a new academic discipline (NESSI, 2007; IBM Academic Initiative, 2007; Spohrer, Maglio, Bailey, & Gruhl, 2007). Service science is taking a growing interest in Service Oriented Architecture (SOA), a framework which promises to develop a flexible and a robust IT-based service capable of responding efficiently to business demands. However, the development of SOA remains at a nascent stage and many early adopting firms find it difficult to establish effective strategies for adopting the framework, especially since they cannot be sure of its successful implementation. The current paper takes the form of an exploratory study based on a review of 34 SOA literatures and 22 interviews and claims to identify twenty factors in successful SOA adoption; the paper subsequently defines a concrete implementation policy for each factor. Comparative analysis, drawing on interviews with vendors and users, demonstrates both similarities and differences in the perspectives presented by a range of research literatures, proceeding to suggest complementary methods of SOA adoption that take account of both vendors' and users' needs. Thus far, research on SOA implementation has not offered a detailed account of the critical success factors (CSFs) conducive to successful SOA adoption. This work thus fills a gap in more closely reflecting the reality of putting SOA into practice.

Service-Oriented Architecture Adoption

Service-oriented architecture (SOA) have been adopted by organizations in a wide variety of industries, however, best practices have still yet to mature. This article, which is part of a larger study on SOA, develops a normative decision model introducing key factors that influence the timing and approach of adopting a SOA. The decision model is based on the results of multiple case studies of organizations that had either employed or were considering implementing a service-oriented architecture project. The results indicate that there are four main areas an information technology (IT) manager needs to assess to determine when and how to move towards a SOA: the maturity of relevant standards, the technology gap, the organizational gap, and the nature of the benefits expected from a SOA. Analyzing these results suggest that differences in the business environment need to be considered in the decision of when and how an IT manager should pursue the move to a service-oriented architecture.

Where Do You Want to Go in Your SOA Adoption Journey?

These days, almost every CIO or IT manager is looking into service-oriented architecture (SOA). Interestingly, adopting SOA isn't the same as deploying a software application, which can be a one-time activity. Rather, it's a journey for an organization over a long period of time - an important detail for everyone involved to understand. Although a few vendors claim that SOA can be quickly and easily implemented with their products, the overall understanding in the industry is that SOA adoption is an evolutionary, rather than revolutionary, process. Not every company has the same needs in adopting a service-oriented architecture (SOA). The authors compare four options for increasing system flexibility.
