Improved software availability quantitative evaluation method based on GOMS model

Abstract

The invention relates to an improved software availability quantitative evaluation method based on a GOMS model, and belongs to the field of software evaluation. According to the improved software availability quantitative evaluation method based on the GOMS model, the use frequency and the importance degree of different services of software are scored by adopting an expert scoring method, so that the weight of each service is determined; the business target is divided into several sub-targets, and the sub-targets can be continuously subdivided until the sub-targets are decomposed into basic operations which cannot be decomposed; on the basis of the basic operation time of the GOMS model, the complexity of different basic operations is calculated; the business complexity is calculated according to the complexity of the basic operation; and the complexity of the software system is obtained according to the complexity of each service of the software system. According to different design schemes of a software system, the software interface design complexity of each scheme is calculated, and the higher the software interface design complexity is, the poorer the software availability is, so that the quantitative evaluation of the software availability of each design scheme can be realized.

Description

technical field [0001] The invention belongs to the field of software evaluation, and in particular relates to an improved software usability quantitative evaluation method based on a GOMS model. Background technique [0002] From the perspective of interface development process, software usability evaluation can be roughly divided into two categories: one is the evaluation in the early stage of software interface design and testing process, which is called staged evaluation; the other is the evaluation taken in the final stage of software interface design, called summative evaluation. Stage evaluation mainly adopts open methods, through questionnaires, interviews, etc., to find out the problems in the design and optimize and improve them; while summary evaluation mainly uses rigorous quantitative analysis, such as completion rate, completion time and other indicators, to improve the interface design. Make an overall assessment. Commonly used testing methods for software i...
