소프트웨어에 대한 인식과 중요성이 대두되고 있으나 아직 소프트웨어 품질에 대한 우리의 관심은 부족한 실정이며, 저질 소프트웨어로 인한 유지보수 업무의 부담과 비용을 가중시키는 것이 현실이다. 따라서 국제표준화 규격인 IS0/1EC 9126에서 제시하고 있는 소프트웨어 품질특성 기능성, 신뢰성, 사용성, 효율성, 보수성 및 이식성을 중심으로 유지보수단계에서의 소프트웨어 품질을 어떻게 측정하고 평가하는 방안과 기법을 제시하고자 한다.

We survey the software faults according to the software characteristics, so we can use it to make a software testcases. We divide the software fault according to six characteristics, functionality, usability, reliability, efficiency, maintainability, and portability. We analyze the software faults to find the common factors according to the software products, also we survey the number of faults according to six characteristics. We propose the method of weight application using the relative comparison of the number of faults.

Software quality is very important in software. We think, software testing is very important in point of functionality, usability. But, we have to consider about all of the software quality. We change our thinking about software quality from time to time. In this paper, we try to the best to find important factors by the number of testing dates and the number of testing in point of functionality, usability, reliability, efficiency, portability, maintainability. We study the mean of the number of faults according to products. We find the difference the number of errors by sex of tester.

ISO/IEC 9126에 의하면 스프트웨어 품질 특성은 기능성, 신뢰성, 사용성, 효율성, 유지보수성, 이식성의 6가지 품질 특성으로 나누어 평가를 실시하고 있다. 각 특성은 부특성으로 나누어지고 이러한 부특성에 따른 평가 항목을 메트릭으로 정의하고 있다. 그러나 품질 특성 중 신뢰성의 경우는 ISO/IEC 9126에서 제시한 부특성인 성숙성, 오류허용성, 복구성, 준수성에 따라 품질 평가 항목이 메트릭으로 제시되어져있다. 그러나 제시되어져 있는 신뢰성 평가 항목은 소프트웨어 신뢰성 성장 모델을 이용하여 신뢰도를 평가하고 메트릭 값을 얻도록 구성되어져 있으나 수리적인 어려움과 데이터 수집에 따르는 문제점으로 인하여 적용하고 있지 못한 실정이다. 이러한 문제점을 고려하여 고장 데이터를 이용하여 소프트웨어 신뢰성을 평가할 수 있는 방안을 검토하고 현재 연구가 진행되어지고 있는 국제 표준 문건 ISO/IEC 25000 시리즈를 국내 표준으로 적용할 수 있는 방안에 대해서 연구한다.

오늘날 선박, 항공, 자동차산업 등의 복합화로 인하여 내장형 소프트웨어의 중요성이 크게 대두되고 있다. 중요도가 높아질수록 고장 현상 발생률이 증가하고 이에 따른 오류나 고장에 대한 영향도 급증 하기 때문에, 신뢰성이 그만큼 중요하게 되었다. 신뢰성은 ISO/IEC 9126, ISO/IEC 12119 등에서 기능성, 사용성, 효율성, 유지보수성, 이식성과 함께 언급되고 있다. 신뢰성의 부특성에는 성숙성, 오류허용성, 회복성, 준수성이 있고, 이에 따라 품질평가 항목 메트릭이 제시되어 있다. 그러나 신뢰성 평가 기준은 수리적 난해함과 데이터 수집에 관한 문제에 부딪혀 적용하는 데에 어려움이 따르는 실정이다. 이와 같은 문제점을 해결하기 위해, 각 세부 평가 항목에 대한 체크리스트를 가지고 품질평가 메트릭에 적용하였다. 또한, 기존에 제시되어 있는 대표적인 신뢰성 모델 두 가지 NHPP(Non-Homogeneous Poisson Process) Model과 Jelinski-Moranda Model을 성숙성과 오류허용성의 품질평가 메트릭과 연관시켜 효율적으로 신뢰성을 측정하는 방안에 대하여 모색하였다.

This study proposed a method for determining weights for the eight quality characteristics, such as functionality, reliability, usability, maintainability, portability, efficiency, security, and interoperability, which are suggested by international standards, focusing on software test reports. Currently, the test results for software quality evaluation apply the same weight to 8 quality characteristics to obtain the arithmetic average. Weights for 8 quality characteristics were applied using the results from text analysis, and weights were applied using the results of text analysis of test reports for two products. It was confirmed that the average of test reports according to the weighted quality characteristics was more efficient.

Many studies have been conducted on software quality evaluation. Recently, as artificial intelligence-related software has been developed a lot, research on methods for evaluating artificial intelligence functions in existing software is being conducted. Software evaluation has been based on eight quality characteristics: functional suitability, reliability, usability, maintainability, performance efficiency, portability, compatibility, and security. Research on the part that needs to be confirmed through evaluation of the function of the intelligence part is in progress. This study intends to introduce the contents of the evaluation method in this part. We are going to propose a quality evaluation method for artificial intelligence software by presenting the existing software quality evaluation method and the part to be considered in the AI part.

Game software is tremendous popularity in inside and outside of the country, so it rises market value. Therefore, it is important to study for the evaluation models of game software. In a general way, I think that ISO/IEC 9126 is the international standard of the software quality testing. Especially, game software quality has been more important on users and developers, so we need the compliance testing model of the game software. In this paper, we evaluate the game software quality objectively and quantitatively, we propose the software quality metrics of testing. Also, we propose the evaluation model of game software on the basis of international standard ISO/IEC 9126, six quality characteristic point of view. That is functionality, reliability, usability, efficiency, portability, and maintainability.

As software is very important, modern men are interesting software quality testing. In this paper, we analyze the Internation standard and Test data, so, we propose the testing method by analysing testing data. We compare ISO/IEC 9126-2 testing model with ISO/IEC 25023 testing model. On the basis of ISO/IEC 25023, we classify the test data and we analyze the difference of International Standard to functionality, reliability, usability, efficiency, maintainability, portability, compatability, and security. By reality 331 testing data, we classify test data, and analyze difference according to sex. We find regression model by functionality, usability and testing date and we prove difference of testing date and the number of error by tester. Also, we prove difference of the number of error in software type.

Many people are interesting software quality. Because of, we depend on software in our life. In terms of, I think, good software is a good quality software. So, when we develop the software, we need trying to improve software quality. In this paper, we analyze software test data. We emphasize that software quality is very important in our life. We use software experimental data, in order to analyze of software quality. On the basis of ISO/IEC 9126-2, we classify the test data and we analyze the difference of error frequency according to functionality, reliability, usability, efficiency, maintainability, portability. We analyze the number of test and used time according software type. We want to search effect variable, going through testing result and measurement convergence, we know the effect variable of functionality and efficiency.
