Consolidating service enginering perspectives

Similar with definition of 'service', the term 'service engineering' (SE) can be broadly defined based on the context and the referring domain. This paper explores the evolutionary definition of SE, with later emphasis on IT/IS perspective. The paper begin with general definition of service and service engineering before elaborating IT perspectives on IT. A review on service orientation, Service Oriented Architecture (SOA) and Service Oriented Methodology (SOM) is also provided in the final part, before concluded with conclusion and suggested future work. In a more general perspective of Service Science, SE is defined as a process of developing newly specified business service, while in IT perspective SE alternately defined as applying service-orientation approach in an enterprise and its IT infrastructure, closely related with SOA approach. Therefore, to consolidate both perspectives, SE can be applied for designing specific business services, as the original definition, combined with bottom up, or meet-in-the-middle approach in the conception of software services during the analysis.
