사용 상황 기반의 모바일 소프트웨어 사용성 품질 속성과 중요도 분석
황만수 한국IT정책경영학회 2021 한국IT정책경영학회 논문지 Vol.13 No.5
In this study, we aim to define the quality attributes of usability for developing mobile software. First, we analyze the user values based on the usage context such as the purpose, method and environment of usage. And we define quality attributes of usability based on these values. Finally, we analyze the correlation between quality attributes by measuring the relative importance and priority for resolving conflicts in developing mobile software.

요구사항 중심의 소프트웨어 개발 생산성 향상을 위한 실증적 연구
황만수 한국IT정책경영학회 2017 한국IT정책경영학회 논문지 Vol.9 No.6
Many existing integrated model-based software developments have been delayed and costly due to imperfect requirements and constant changes. In order to solve these problems, it is developed software system using software split ordering based on definition of complete requirements. In reality, however, It is still difficult due to the uncertainty of the initial requirements. In this paper, we identify the problem of requirements and analyze the cause of problem after applying the software split ordering to the case project. And we suggest improvement method by applying requirements engineering process and methodology. So we can increase the productivity of software development.

시니어 계층의 디지털 리터러시 향상을 위한 키오스크 소프트웨어 사용성 요구사항 추출
황만수 한국IT정책경영학회 2023 한국IT정책경영학회 논문지 Vol.15 No.4
Kiosk systems, which are expanding in essential areas of society, have low usability among information-vulnerable groups. In this study, we aim to improve the digital literacy of the senior class by developing software that encourages active use rather than improving existing aesthetic services or UI. Therefore, we divide the entire service into three stages from a usability perspective: access, action, and confirmation. And we elicitated six usability requirements from psychological, behavioral, and cognitive perspectives. We also calculated the relative value of the requirements using AHP to convert from abstract usability requirements to architectural requirements, so we extracted business drivers and verified their validity.

황만수,민태홍 한국컴퓨터산업학회 2003 컴퓨터産業敎育學會論文誌 Vol.4 No.4
As the Software development condition is changed into enlargement and complex, requirements generated in each step of Software development life cycle has important effects on the technique and management area. In this thesis, We propose so engineering approach for effective and systematic process and activities including Requirements acquisition and management based on activities proposed with Requirements Engineering and CMM that my special emphasis is putted on Software qualify improvement through the reduction of software development cost and danger.

소프트웨어 요구사항 명세 품질 향상을 위한 결함 분류 및 예방 전략
황만수 한국IT정책경영학회 2018 한국IT정책경영학회 논문지 Vol.10 No.6
Software systems are inevitably defective throughout the development life cycle. In particular, defects that occur in the requirements phase are difficult to identify and remove, which can lead to development failure or quality deterioration by affecting the downstream development stage. Therefore, it is required to manage the quality of requirements initially. In this regard, most of the existing studies for eliminating defects focus on finding defects through inspection of written software system requirements specification, and suggesting defect detection techniques, cause analysis and prevention methods. Nonetheless, actual requirement defects continue to occur. Therefore, this study aims to prevent defects by analyzing the problems that occur in the initial business requirement definition phase of the requirements engineering process, and proactively detecting the causes and symptoms of potential defects and suggesting solutions. This enables successful software development based on high-level business requirement quality.

상용SW 재사용 기반 SW 개발 비용 효과성의 실증적 연구
황만수 한국IT정책경영학회 2022 한국IT정책경영학회 논문지 Vol.14 No.4
In this study, we aim to provide quantitative information that COTS-based SW is more cost-effective than SI development when solving low SW development productivity and quality problems. we first select some SW development projects on public domain with a relatively low success rate, and then we compare the SI development cost calculated based on the function point with the commercial SW-based development cost estimated using the Delphi technique. Finally, we verify the cost effectiveness between the two development methods based on the validity of SW project selection, the suitability of COTS application, and the accuracy of the SW project cost.

소프트웨어 개발과 운영이 분산화, 대형화됨에 따라 정확하고 완전한 요구사항의 추출과 명세는 시스템의 가장 중요한 요소가 되고 있다. 또한 인터넷을 통한 공동작업 환경에서 계속적인 시스템 변경요청은 더욱 효율적인 요구사항 관리를 필요로 한다. 본 논문에서는 이러한 공동작업 환경에서 자연어 기반 요구사항 명세와 관리의 효율성을 향상시키기 위한 요구사항 명세구조와 기법 등을 정의하고, 요구공학 활동과 주기를 바탕으로 하는 요구공학 프로세서와 환경을 제안한다. 그래서 CSCW(Computer Supported Cooperative Work) 환경에서 요구사항을 정확하게 추출하고 효율적으로 관리하며 분석단계로 자연스러운 전이가 가능하도록 한다. According to distributed, large-caled environment of software development and operation, the elicitation and specivication of correct and complete requrement is the most important factor for the system. In addition contiuous and dramatic systerm canging requests in cooperative environment with internet require more efficient, requirement management. In this paper we detine the specification architecture and techruques for requrements, so that we improve the efficiency ofnatural language-based requirement speciticationand management in a cooperatie work environment. Also, we propose a software requirement engineering process model and environment based on requirements in a CSC@(Computer Supported Cjooperative Work) environment, therefore transfer them into analysis phase.

다중 프로세서 시스템을 위한 전송에러 Recovery의 모델링
황만수,황대훈,김영찬 한국정보과학회 1986 한국정보과학회 학술발표논문집 Vol.13 No.1
다중 프로세서 시스템 상에서 각 프로세서의 entity간에는 정보의 교환이 요구되며 또한 이들정보의 전송중 에러가 발생할 수 있다. 본 논문에서는 Petri Net를 이용하여 entity 사이에 관계와 Protocol을 모델링하고 전송에러가 발생했을 경우 이를 감지하여 회복시킬 수 있는 기능을 모델링한다. 또한 Petri Net의 분석기법을 이용하여 이 모델이 갖는 특성을 분석한다.
