Service Identification Methods: A Systematic Literature Review <s> Introduction and Research Questions <s> Although the benefits of service orientation are prevalent in literature, a review, analysis, and evaluation of the 30 existing service analysis approaches presented in this paper have shown that a comprehensive approach to the identification and analysis of both business and supporting software services is missing. Based on this evaluation of existing approaches and additional sources, we close this gap by proposing an integrated, consolidated approach to business and software service analysis that combines and extends the strengths of the examined methodologies. <s> BIB001 </s> Service Identification Methods: A Systematic Literature Review <s> Introduction and Research Questions <s> Thank you for reading service oriented architecture soa compass business value planning and enterprise roadmap.

Service-oriented architecture (SOA) is an architectural enabler for quick response to business changes and effective reuse of software assets BIB002 . In an ondemand world, many enterprises have adopted SOA in order to gain competitive power BIB002 . A key factor that determines whether an enterprise really can benefit from adopting SOA is the design of services, including the scope of functionality a service exposes to meet business needs, and the boundaries between services to achieve maximum reusability and flexibility BIB003 . In the design of services, service identification (SI) is a significant task aiming at determining (based on available resources) services that are appropriate for use in an SOA. Many service identification methods (SIMs) have been proposed from both academia and industry. However, these SIMs differ significantly, ranging from source code extraction to business domain analysis, from bottom-up to top-down strategy and from ontology-based process to guideline-driven process. Accordingly, the inputs and outputs of these approaches vary as well. Some approaches start with business process whereas some others start with domain knowledge (e.g. goals and strategies); some approaches focus on business services whereas others focus on software services. Given many SIMs, a common question that practitioners face is how to select the most appropriate SIM that copes with the available resources and fits their needs BIB003 . Some enterprises, for instance, not only have well defined business process models in place but also well documented goals, business partners and enterprise capabilities (e.g. IT resources) to support its business process. For them, a SIM that takes all of this information into account will be more suitable than those identifying services only based on e.g. business processes. Despite the comparisons (e.g. BIB001  ) presented so far, none systematically searches for all the existing SIMs. As a result, a holistic overview of extant SIMs is missing. Moreover, the criteria used in the existing comparison frameworks cover many aspects, including economic, business, and technical aspects. However, a comparison of the basic elements (such as the inputs, outputs and processes) of the SIMs is currently missing. When selecting SIMs one often starts questioning what is required for using certain SIMs, what can be expected from them and how to carry them out, before addressing other requirements. Without such an overview of the basic elements of SIMs, the selection of SIMs becomes more complicated. Accordingly, the following research questions arise: To answer these research questions, we decided to conduct a systematic literature review, which are particularly powerful in collecting and analyzing existing work. It can maximize the chance to retrieve complete data sets and minimize the chance of bias and summarizing the existing evidence  . In the remainder of the paper, Sec. 2 reports on the review results; Sec. 3 presents an input-output matrix that aids the selection of SIMs; and Sec. 4 concludes the paper.
