In real software business environment, there are required to validate software quality in diverse usage range of software for many small & medium companies. Software quality means both qualities of production and process. In our situation, we focus on better process quality of a test organization than a whole organization. But even the original test maturity model (TMM) does not enough to apply with our domestic venture/small & medium companies. To solve this problem, we suggest the simplified test maturity model for our companies. We redefine this simplified model with the original TMM and a test process improvement next (TPI next) model. The previous models just have provided each definition of maturity level, goal and activity per each level, which not exists an assessment guideline and a formal assessing procedure. Due to this reasons, an assessor is difficult to assess the test organization without them. this paper suggest an assessment guideline of the simplified TMM and also define the procedure which is included with activities and byproducts. With these assessment guideline, an assessor can work possible to formally assess test organizations of small & medium companies, and with self assessment guideline they can be correctly provision before assessment of their organizations.

The interest in software defects is growing. Companies are working on reducing them by various ways with a software development part, customer service part and quality management part. The defect data collected from them will be analyzed according to the condition and purpose to minimize the defect, and it will contribute to improving the quality of products. This study analyzed the software defect progress for companies based on the test maturity model, and set up the defect preventing process. They were applied to the project, and the number of defects decreased from 106 to 16. This study focused on the existing defect, which is a basic requirement for software quality management, and have importance by presenting a way to improve the software product quality with minimum resources.

In the past, when the personal information leakage incident of the three card companies, the computer program development was followed by the same strict electronic financial supervision regulations as the operating environment. However, when developing a computerized program, the application data is being verified with the integrity of the test data being compromised because the identification of the scope of conversion of the test data associated with the application is unclear. Therefore, in this paper, we proved by presenting a process and algorithm for selecting a range of sufficient test data conversion targets associated with a specific application.

새로운 생활공간으로서 수상공간에 대한 관심이 증가하고 있으며 수상공간을 보다 적극적으로 활용하기 위하여 부유체를 이용한 플로팅 건축물의 사용이 증가하고 있다. 하지만 플로팅 건축물의 설계 및 설치에 있어 적용되는 법제도가 명확하지 않아 많은 관련사업을 진행함에 있어 많은 어려움을 초래하고 있다. 최근 설치된 플로팅 건축물 적용 법제도 사례를 통해 설계 및 설치를 위해서는 가장 먼저 법적 지위에 대한 명확한 기준이 필요하며 입지하는 수역에 대한 법제도를 검토할 필요하가 있다. 본 논문에서는 명확하지 않은 플로팅 건축물 법제도를 정비하기 위하여 플로팅 건축물 테스트베드를 설계하고 설치하는 프로세스를 통해 적용되는 법제도를 검토하고 문제점 및 개선 방법을 도출하여 보다 용이하게 플로팅 건축물을 설치할 수 있도록 하였다.

Test environment on the company that handles a large amount of data such as telecommunications companies and financial institutions, may not always be the same as the production environment, which is caused by conversion of important columns about information and limitation of storage capacity due to the construction cost. Therefore, SQL performance degradation that occurs when the test and production environments are not the same, which is an important cause of connecting to the unexpected failures of online transactions, and it generates financial loss of business, customer complaints, a decrease in reliability. In studies related SQL performance, it has so far been conducted mainly studies of tuning associated with DBMS Optimizer, and it has not been addressed issues of this sector. Therefore, in this paper, I verify the validity about presentation of the advanced SQL Performance-based IT application change management process, in order to prevent failures of the online transactions associated with poor performance of SQL generated by differences in test and production environments.

Depending on the size and complexity of the game, interest in game quality control is increasing. The quality of the game can be evaluated through fun and stability tests, and the player's satisfaction varies greatly accordingly. For the quality control of the game, Fun QA is in charge of testing to increase the fun and give satisfaction to the players. In this study, we first looked at software quality improvement techniques and game QA work. And in order to improve game quality, we analyzed Fun QA, which is relatively unstructured compared to Technical QA, which is mainly responsible for stability testing. Based on this, the Fun QA process was proposed and an example of Fun QA design was presented using real games. It is expected that this study will be one of the pillars of the game quality management area pursuing quality improvement by guaranteeing fun. Furthermore, it is expected to help QA workers expand their work area.

The hardware-based software has been loaded in almost all industrial fields including the embedded system field. As it is increasingly important to control product quality, the more businesses are expending great quality cost. However, most domestic corporations in Korea are bent on spending more money solving problems caused by poor quality rather than prevention of quality loss cost. Therefore, it's time to improve to use quality prevention cost efficiently. As for this, there has been a growing interest in controlling quantitative quality, but the managing activities for quantitative quality require a high maturity process, belonging to Level 4 and 5. So it is necessary that statistical quality control activities should be fulfilled. This study introduces various measures to build up quality control among the process areas of TMMi Level 5 to help establish the high maturity test processes of statistical quality control.

소프트웨어의 크기가 커지고 복잡도가 증가함에 따라 소프트웨어 품질의 중요성은 점점 증대되고 있다. 소프트웨어의 품질 향상을 위해 소프트웨어 개발 조직은 테스트와 동료검토와 같이 제품 품질 향상을 위한 노력과 CMMI(Capability Maturity Model Integration), 소프트웨어프로세스 품질인증 기준과 같은 프로세스 품질 향상 노력을 하고 있다. 그러나 이러한 소프트웨어 분야의 품질 관리의 노력과 효과에 소요되는 품질비용에 대한 연구는 제조업이나 건설업 등 타 분야에 비해 부족한 실정이다. 본 연구에서는 소프트웨어 프로세스 개선을 위한 모델인 CMMI의 성숙도 레벨에 기반하여, K사의 품질비용관리 방안 적용 결과를 바탕으로 CMMI 성숙도 각 레벨마다 소프트웨어 개발 조직이 품질비용을 관리를 위한 목적과 활동으로 정의된 품질비용 관리 모델의 개발을 연구하였다.

Software development undergoes a number of iterations and each iteration forms its own cycle going through requirement analysis, scheme and design, implementation and finally test and evaluation. In this iterated development process, executable releases are produced, improved and eventually developed to a complete system, going through this particular development cycle. Compared to the conventional process, the advantage of rapid iterative development process lies in reducing risk factors in early stage and responding to changes very flexibly. In addition, highly reusable, the process can improve capabilities of the development team while the project is being carried out. As a result, overall balance in quality is secured. The objective of this paper is the research of rapid development process and its case studies showing how to adapt the rapidly changing customer requirements and to transform those requirements into the project timely and adequately. The proposed process is focused on the common and core activities of NET-based MarMIIII, MSF/CD, XP, Agile, PSP and TSP
