On The Quantitative Assessment Of Software Quality

With the growth of knowledge in the field of software quality, software quality in the international standardization organizations have done a lot of work, at present, started its research focus on two areas :1) the quality assurance process of software development, process management and document scientific content.2) the software process and product quality assessment, including intermediate and final products. Software Quality Metrics software technology as the main technical characteristics quantified.Internationally popular series of ISO standards and is the most representative model, the CMM. IEEE std1061-1992.The domestic software industry practice for software quality control and research is not enough, there is no clear assessment of the software quality criteria and benchmarks difficult to achieve quantitative evaluation;The use of software metrics subject of the latest research results, based on the software development practice. Quantitative assessment model for software quality control and research.We think the overall quality of the software is uncertain. Different types of software requirements of the different elements of Software Quality, therefore in the system design process must be based on specific requirements of various elements of a compromise. to be on the whole system developers and users are satisfied with the quality standards.In this paper, according to ISO9126 Quality Metrics software and software life-cycle model, Software Quality Metrics in formulating the framework of the three-tier structure. In this framework model, the upper level is the quality of management-oriented elements, Each element is used to describe and evaluate the quality of software quality attributes of a group representing one aspect of software quality. Software quality is not only from external manifestations of the characteristics of the software to determine, but must have the characteristics to determine its internal. The first factor is the quality of the upper sub-elements of quality and refinement, it could be a number of specific sub-elements quality factor. Sub-element of the software quality management and technical staff on the issue of software quality channels of communication. Software Quality Metrics factor is the bottom (including parameters), used to measure the quality factor. Quantitative measurement factor can be measured directly or statistics. to be the final element of software quality and value of sub-elements provide a basis for value; For non-quantitative measure of each stage of a factor questionnaire. this software development process quality control.
