Research of service computing in the last 10 years has benefited the organization in using and applying service computing technology to improve its service system. The development of service computing technology sparked the need of organizations in building a service computing system that has capability for delivering IT services that can meet the requirements of business services. Through service computing technology, service innovation can be achieved by the organizations to improve service productivity and quality. Research in service design areas are a key challenge in service computing research. The understanding and knowledge of service design is essential as a prerequisite for developing the service system. The challenges in the service design area are crucial along with the application of service computing to the organizations for seeking and require the optimized services computing systems engineering methodology to realize the design of the systems. One of the major challenge in the development of a service computing system is the lack of a formal engineering methodology that capable of providing a fully serviceoriented application development environment that meets the characteristics of the services computing systems and computing resources of the organization. Service oriented architecture (SOA) plays an important role in the development of application services and is required for those application services to be fully integrated, interact, and function effectively. In addition to that, the development of engineering methodologies in the design of services computing systems is needed to build service-oriented applications that capable of interacting with each other within an integrated system. Some of the engineering research in the area of services computing systems have addressed various issues in the area of services computing systems architecture, service computing system methods, and service composition. However, these studies still can not provide a formal engineering methodology for building the systems that meet the characteristics of the organization and/or the needs of service users, as well as aligning the IT services to business services of the organisations. In addition, the lack of methods and techniques to the engineering process of the methdology also still leaves the research gap. iv The development of a services computing systems engineering methodology is a very important issue given the need provide a fully service-oriented application development environment that suits the service computing system characteristics and computing resources of the organization. The development of a service computing system engineering methodology implements SOA in building IT service systems. The development for the appropriate service computing system engineering methodology that complies to the implementation requirements of SOA is needed to build service-oriented systems that have capabilities for the interaction and integration among the systems. The methodology is needed to design and build a service-oriented system that perform the systems interactions and interoperabilities. This research will develop a services computing systems engineering methodology based on SOA using engineering approach. This research will develop a service computing system platform reference model as a basic guide to understanding the components needed to build a service computing system within platform (system development environment). The research will also develop the computational methods and techniques required to evaluate the development process of the methodology as well as to measure the performance of the systems. The output of this research is a services computing systems engineering methodology. The development of the methodology covers a reference model, life cycle, framework, methods and techniques, prototype, evaluation of the whole process of service computing system development. The reference model will describe and identify the components needed to model the service computing system. The reference model to be built is in the form of a service computing application layer. Furthermore, the life cycle model will describe the metamodel of the service computing system and describe the life cycle of the service computing system development, while the resulting framework will be used as the methodology in designing, building, implementing and running the systems. Methods and evaluation techniques to operationalize and to evaluate the methodology are also proposed, i.e. the method of measuring the development process of the systems using the proposed methodology and the method of measuring the performance of systems. The contribution of this research is to improve the understanding and knowledge of service computing, service computing technology, service computing systems, and service computing system development from the engineering approaches.
