Research On Organization Level Software Generalized Quality Characteristic System And Its Information Construction

With the rapid development of information technology, software systems have been applied to many fields. Meanwhile, the generalized factors which influence the software quality have increasingly attracted people's attention. View of the current software enterprises to improve the quality of the urgent needs of software, it is very important to research and design an information platform of software quality guarantee. For this reason, the thesis focuses on the Organization Level Software Generalized Quality Characteristic System and its utilization in the information platform of the software quality guarantee.The thesis discusses the points of requirement and the system goals for the information construction of the generalized quality system, presents the generalized quality characteristic system in accordance with the organization-level software process model and oriented to the organization business goals. An information platform prototype which is designed of process management, generalized quality characteristic management and external quality guarantee system is established, and the related key technologies is described, including the quantification, measurement, and information-based construction of the generalized quality characteristic system.The thesis quantifies and measures the organization level software generalized quality characteristic system on the basis of analyzing basic quality characteristic, customer value characteristic, organization management characteristic and comprehension balance characteristic and by the top-down hierarchical approach. Some characteristic items are studied such as reliability, feasibility, manageability, custom satisfaction and schedule objectively, dividedly and measurably. The application of the generalized quality characteristic system is elaborated on the aspects including the evaluation principles, indicators tailoring, matrix model, data collection and associated measurement and equilibrium.Against the signification and objectives of the information support, the thesis presents the information models both internal and external, describing the input, output, information flow in them. The generalized quality characteristic system links up the organizational level process model via the external information model, facilitating the goal orientation of the enterprise, software process measurement and the treatment across projects and in organization level.A quality guarantee information platform prototype is built oriented to small and medium-sized enterprises, validating the researched generalized quality characteristic system and related techniques.
