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.

Recently, E-Learning based on wide-area infrastructure is being spotlighted as the new means to innovate education at school and develop human resources at society and appeared as the main point of digital content industry. In this paper, we analyze the characteristics of base technology of E-Learning software and developed E-Learning software quality evaluation model by analyzing quality characteristics for quality test and evaluation of E-Learning software. To do so, we established the quality evaluation system and developed the evaluation model to evaluate the quality about E-Learning software by introducing related international standard. We think that this will promote development of competitive E-Learning software products.

This paper presents industry feedback and a case of improvement trial on enabling reuse driven software development which is one of several activities to improve software quality and productivity in a company which develops software that are embedded into consumer electronic products. Several case studies will be introduced that are related to software reuse strategies and practices to show how to establish environment for reuse basis in a company, how to apply it to development team and project and how to improve that through trials and errors. To enable reuse-oriented software development in a huge company, integrated and focused approach is needed among technical, management and environmental point of view. We tried to solve that problem in technical field with reuse method, in management filed with reuse metric and in environment field with reuse repository. The characteristics of our software development environment could be summarized as below. The first, embedded software which would not independent to hardware devices and the second, it is very huge company which develops extremely various products by many different organization with different domain characteristics and the third, development lead time is extremely short and many variation models are stems from basic models. We expect that our study would give contribution to industry struggling to solve similar problem for presenting our experience and could be a reference model for enabling software reuse in a real world practically.

International standard for software quality evaluation, ISO/IEC 9126 defines the quality characteristics and sub-characteristics consisting of quality of the software. Also, in this standard, the quality assessment items are presented in metrics based on maturity, fault tolerance, recoverability and compliance which are sub-characteristics of reliability. However, this reliability assessment items which are presented are not applied now due to the mathematical difficulties and the problems caused by collection of data. In order to resolve these problems, this study introduces measures to develop a specific test technique by quality attributes and to measure the quality. In other words, the detailed guidelines are presented to be utilized as a standard by summarizing test activities and techniques by each development life the most commonly used. The SW quality results are derived by assigning weights to software in order of the most important quality characteristics of respective software using checklist that can be easily utilized and applying test technique that can be utilized for detailed evaluation items and checklist. This improves problems that include reliability assessment item of ISO/IEC 9126 as the measures to measure new reliability quality of software.

Architecture base mechanism centers to construct software system. There is construction of successful software system how firmly define software. Reason that architecture base software is important is used and expresses early design decision item of system and is because reusability is possible by means of communication between comprehension person concerned. Analyzed special quality of pattern and importance of architecture and general requirement and portability and consider ISO/IEC 9126 and ISO/IEC 14598 and propose system and Metrik in this research. Also, do defect particulars and efficiency test that test according to examination formality of architecture base software and analyzed result.

컴포넌트 기반 개발은 컴포넌트 재사용을 통해 생산성을 향상시키고, 검증된 컴포넌트의 사용으로 소프트웨어 품질을 증대시키며, 개발비용 및 일정의 단축을 유도하는 등 기존의 소프트웨어 개발 방법에 비해 다양한 이점을 보유하고 있다. 이러한 이점에도 불구하고 컴포넌트 기반개발을 성공적으로 정착시키란 쉬운 일이 아니다. 이는 바로 컴포넌트 기반 개발의 특성상 발생할 수 있는 위험을 체계적으로 관리하지 못했기 때문이다. 본 논문에서는 컴포넌트 기반 개발 시 발생할 수 있는 위험을 분석하고 영향을 미치는 측정 메트릭을 조사하여 위험을 정량적으로 측정하기 위한 초석을 마련하였다. 또한 컴포넌트 기반 개발 시 발생할 수 있는 위험을 체계적으로 관리하기 위한 'CBD 개발과제 위험 노출도를 줄이기 위한 OT(Opportunity Tree)'를 제시하였다.s;를 제시하였다.

효과적인 소프트웨어 프로세스 개선을 위해 SPICE와 CMMI 프로세스 심사 표준을 도입하려는 노력을 하고 있다. 이러한 표준을 통해 효과적인 개선하기 위해서는 개선점과 위험을 식별하고 이들 이슈들을 개발환경에 적용시켜서 조직의 비전에 대응한 작업성능을 높여야한다. 지속적인 개선을 필요로 하는 조직은 현재의 작업성능을 측정하고 이를 개선하기 위한 개선점을 찾아내는 능력과 경험을 축적하여 체계적으로 관리하는 것이 중요하다. 하지만 기존의 SPI 모델들은 무엇을 수행해야 하는지에 대한 지침은 제공하고 있지만, 정량적인 작업성능 측정 및 특정 환경의 소프트웨어 개발 조직의 SPI를 위해 필요한 구체적인 지침을 제시하고 있지는 않다. 따라서, 본 논문에서는 정량적인 SPI룰 위해 프로세스 측정 메트릭 정의와 심사 경험이 분석되어 활용될 수 있는 PCM(Process Capability Metric) Experience Factory 모델을 제안한다.

Ubiquitous Computing System (UCS) is a system where the user can get information through computer network anytime and anywhere regardless of the places. Since UCS is a personalized system, it should interact with other systems. UCS will bring a remarkable change in production, consumption, politics, economy, community, culture, and other areas related to our daily life. That is, a high-quality UCS results in high-quality services provided to users. Hence, this paper proposes a systematic quality model based on ISO/lEC 9126 in order to evaluate the ubiquitous computing system, based on ISO/lEC 9126. And, we identify key characteristics of UCS and derive the set of quality attributes based on identified characteristics. We define metrics for each quality attribute and Ubiquitous Computing Quality Model CUCQM) so that we can evaluate overall environment and important characteristics of UCS.

Recently. component-based software development is getting accepted in industry as a new effective software development paradigm, Since an introduction of component-based software engineering(CBSE) at later 90's, the CBSD research has focused largely on component modeling, methodology, architecture and platform, However. as the number of components available on the market increases, it becomes more important to make metrics to measure the various characteristics of components. In this paper. we propose metrics for measuring the complexity, customizability, and resuability of software components, Complexity of metrics can be used to evaluate the complexity of components Customizability is used to measure how efficiently and widely the components can be customized for specific requirements organization, Resuability can be used to measure the degree of features that is reused in building applications.
