PSP(personal software process)는 소프트웨어 개발자들이 양질의 코드를 생산할 수 있도록 개발된 정밀하면서도 계량적인 수치를 기반으로 한 소프트웨어공학 기법이다. PSP의 효과적 학습을 위해서는 프로젝트에서 발생하는 많은 양의 데이터를 계산하고 기록하는 작업을 필수적으로 행해야만 한다. 이 작업은 많은 시간이 소요될 뿐 아니라, 오류의 발생이 쉬워 PSP 학습의 동기와 효과를 감소시키는 결과를 초래한다. 이를 개선하기 위해서 본 연구에서는 데이터의 정리, 검증 및 분석을 처리할 수 있도록 웹 기반의 PSP 로그 시스템을 설계하고 구현하였다. 3년간의 실험 결과는 이 시스템이 생산성과 정밀도를 높일 뿐만 아니라, 데이터의 처리보다는 PSP 기법의 프로세스에 대한 학습과 교수에 더 집중할 수 있게 해주었음을 보여주었다.

본 논문은 프로젝트 환경과 특성을 고려하여, 소프트웨어 개발 경로를 커스터마이징 하는 방법을 설계한 것이다. 개발 경로 선정 기준은 ISO/IEC TR 15721 Information Technology Guide for ISO/IEC 12207(Software Life Cycle Processes), ISO/IEC 15504 Information technology - Process assessment의 프로세스 내용에 기반 한 10개의 영역 특성이다. 10개의 영역 특성은 프로젝트 환경과 특성을 반영한 것이며, 프로젝트 개발 경로 선정 항목들을 정의한다. 프로젝트 환경과 특성 항목인 10개 영역 특성 항목을 이용하여 소프트웨어 개발 프로세스를 선정하는 알고리즘을 제시한다. 본 논문에서 제안한 소프트웨어 개발 경로를 커스터마이징 하는 방법을 평가하기 위하여 소프트웨어 개발 경로를 커스터마이징 하는 방법을 반영한 개발 경로 선정 시스템을 가지고 웹 기반 시스템 개발 프로젝트를 적용한다. 그러나 입증된 수작업 프로젝트 경로 프로세스와 시스템에서 출력된 프로젝트 경로 프로세스가 차이가 난다 차이가 나는 주원인은 산출물이 서로 합쳐졌거나, 명칭이 바뀌었기 때문이다. 효과로는 소프트웨어 개발 프로젝트 환경과 특성에 적합한 경로 프로세스를 용이하게 선정한다.

In this paper, we Present the implementation of statistical process control software by using XLISP-STAT which is a kind of object oriented language under Windows environment. This software can be used to generate the graphic objects for various control charts, histogram and plots using the full-down menu system. This software can also be used to calculate control limits, process capability indices and test procedures for normality.

Auditing plays a very important role in the process of developing and managing good quality software. The software developing proces should be audited precisely especially in the test phase. Up to the present, because auditing has depended on the auditor's experience of developing and auditing software, it has been impossible to audit objectively. It is limited to audit systematically and objectively because auditing process isn't systematized. In this paper, the auditing model to solve several problems in present auditing is suggested, a test phase audit system is developed, and the system is applied to the actual auditing process. Consequently, software administrators can establish effective software management, software developers can be supported by a highly reliable and quality software development tool, and auditors can be offered an objective audit standard.

This paper presents the ways that can improve the Software Cost Estimation Guidelines in order to replace those that are expected to be abolished at February, 2012, and solve the problems that are being occurred in the current Software Cost Estimation Guidelines. By using multidimensional modeling of OLAP(On-Line Analytical Processing), this paper does three dimensional modeling that considers the product/service view, process view and skill view. Also, it presents the identification method of cost estimation data through the view of each dimension. Furthermore, it defines the software cost estimation process and adapts them into the bottom up estimation and the top down estimation. Finally, it proposes the access of cost estimation data by the multidimensional analysis of OLAP.

Large software systems are being produced with a noticeably higher level of quality with component-based software engineering (CBSE), which places a strong emphasis on breaking down engineered systems into logical or functional components with clearly defined interfaces for inter-component communication. The component-based software engineering is applicable for the commercial products of open-source software. Software metrics play a major role in application development which improves the quantitative measurement of analyzing, scheduling, and reiterating the software module. This methodology will provide an improved result in the process, of better quality and higher usage of software development. The major concern is about the software complexity which is focused on the development and deployment of software. Software metrics will provide an accurate result of software quality, risk, reliability, functionality, and reusability of the component. The proposed metrics are used to assess many aspects of the process, including efficiency, reusability, product interaction, and process complexity. The details description of the various software quality metrics that may be found in the literature on software engineering. In this study, it is explored the advantages and disadvantages of the various software metrics. The topic of component-based software engineering is discussed in this paper along with metrics for software quality, object-oriented metrics, and improved performance.

The main focus when developing software is to improve the reliability and stability of a software system. We are enjoying a very comfortable life thanks to modern civilization, however, comfort is not guaranteed to us. Once software systems are introduced, the software systems used in the field environments are the same as or close to those used in the development-testing environment; however, the systems may be used in many different locations. Development of software system is a difficult and complex process. Generally, existing software reliability models are applied to software testing data and then used to make predictions on the software failures and reliability in the field. In this paper, we present an improved exponential NHPP software reliability model in different development environments, and examine the goodness-of-fit of improved exponential model and other model based on two datasets. The results show that the proposed model fits significantly better than other NHPP software reliability model.

As the importance of non-functional requirements has increased, many researchers have become interested in the software development process for non-functional requirements including the notation, modeling, and assessment of non-functional requirements. However, the characteristics of non-functional requirements are so sophisticated and there are many topics which have not been solved until now. In order to address one of the unsolved problems, we propose a systematic software development process to support the management of non-functional requirements. The process consists of six steps, each of which is composed of detailed activities. Using the proposed process, the non-functional requirements can be managed and modeled more effectively and systematically than previous ones.
