Influential trend that widely reflected the software engineering industry is service oriented architecture. Vendors are migrating towards cloud environment to benefit their organization. Companies usually offer products and services with a goal to solve problems at customer end. Because customers are more interested in solution of their problem rather than focusing on products or services. In software industry the approach in which customers' problems are solved by providing services is known as software as a service. However, software development life cycle encounters enormous changes when migrating software from product model to service model. Enough research has been done on the overall development process but a limited work has been done on the factors that influence requirements elicitation process. This paper focuses on those changes that influence requirement elicitation process and proposes a systematic methodology for transformation of software from product to service model in a successful manner. The paper then elaborates the benefits that inherently come along with elicitation process in cloud environment. The paper also describes the problems during transformation. The paper concludes that requirement engineering process turn out to be more profitable after transformation of traditional software from product to service model.

SaaS는 소프트웨어 개발 및 배포에 있어 전체적인 비용을 크게 줄일 수 있는 새로운 패러다임으로 분산 컴퓨팅, 그린 컴퓨팅, 클라우드 컴퓨팅 동의 최신 컴퓨팅 플랫폼에 있어 중요한 기반기술로 여겨지고 있다. 이러한 SaaS는 기존의 소프트웨어와 달리 높은 수준의 설정 가능성(Configurability)을 요구받고 있으며, 이에 따라 설정 요구사항(Configuration Requirements)의 추출에 있어 모든 설정 가능성을 빠짐 없이 고려하는 것이 매우 중요하다. 본 연구에서는 SaaS의 특성에 따라 각 요구사항에 대한 설정 가능성이 누락되지 않도록 결정할 수 있는 분류 기법을 제안한다.

Requirement engineering is being highly required for developing a new system nowadays because systems become more and more complex. System engineers require clear and distinct user requirement to avoid mistakes taking placing and mitigate the risks such over cost, schedule delay, and performance degradation during system engineering activities. The exact requirement elicitation make it possible to develop a systems to meet users need. In this paper, we presented a process and methodology to develop requirement for application to Automatic Train Control System. In the methodology and process presentation. we presented a key words to elicit requirement and showed how to analyse and validate the given requirement for ATC system.

The primary goal of the requirement analysis phase during information system development is to identify and document what is really needed, in a form that clearly communicates to the user and to development team members. Presented in this paper is a QFD(Quality Function Deployment)-based requirement analysis method and procedure for developing a large-scale enterprise information system. For the purpose of elicitation of software functional requirements, this paper adopts the method of HOQ(House Of Quality) and proposes a simplified HOQ which is more suitable for the software requirement analysis. As a result of this paper, it suggests desired functionalities for an integrated design &manufacturing information system.

요구사항 추출 활동은 다양한 이해당사자의 요구를 요구사항으로 추출하고 협상을 위한 정보를 생성하는 사전 준비 작업이다. 그러나 현재 고객으로부터 요구사항 수집을 위한 기법은 다수 존재하고 있으나, 요구사항 분류와 협상을 위한 정보 제공에 대한 연구는 부족한 실정이다. 본 연구는 요구사항을 분류하고, 협상을 위한 정보를 식별하는 기법에 대한 연구이다. 본 연구는 요구사항 분류를 위해 Kano 모델과 통계 기법을 활용하였으며, 협상을 위한 정보를 생성하기 위해 요구사항과 문제의 관계를 고려하였다. 제안한 기법에 대한 시뮬레이션, Rough Set Theory, 사례 검증을 수행하여 제안한 방법의 타당성을 검증하였다.

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.

For mobile service organizations, it is one of the most important tasks to reflect users' opinions rapidly and accurately. In this study, the process is defined to elicit requirements of software/system improvement for mobile application by extracting and refining from users' opinion in mobile app, and detailed activities procession method in this processing are also proposed. The process consists of 3 activities to get requirements of software/system improvement for mobile app. First activity is to transform mobile app to software structure and define term dictionary. Second activity is to elicit simple sentences based on software from users' opinion and refine them. The last activity is to integrate and adjust refined requirements. To verify the usability and validity of the proposed process and the methods, the outputs of manual processing and semi-automated processing were compared. As a result, efficiency and improvement possibility of the process were confirmed through extraction ratio of requirements, comparison of execution time, and analysis of agreement ratio.

There has been a rapid growth in the development of mobile application resulting from its wide usage for online transaction, data storage and exchange of information. However, an important issue that has been overlooked is the lack of emphasis on the security issues at the early stage of the development. In fact, security issues have been kept until the later stage of the implementation of mobile apps. Requirements engineers frequently ignore and incorrectly elicit security related requirements at the early stage of mobile application development. This scenario has led to the failure of developing secure and safe mobile application based on the needs of the users. As such, this paper intends to provide further understanding of the real challenges in extracting security attributes for mobile application faced by novice requirements engineers. For this purpose, two experiments on eliciting security attributes requirements of textual requirements scenario were conducted. The performance related to the correctness and time taken to elicit the security attributes were measured and recorded. It was found that the process of eliciting correct security attributes for mobile application requires effort, knowledge and skills. The findings indicate that an automated tool for correct elicitation security attributes requirement could help to overcome the challenges in eliciting security attributes requirements, especially among novice requirements engineers.

Recently, many enterprises have attempted to capitalize knowledge assets on data warehouse (DW). It has been recognized as strategic core process to create corporate competitive advantage and implement enterprise e-biz strategies. However, most approaches to represent knowledge and decision process have limits in considering various knowledge types, their relationships and continuity in knowledge formulation. In addition, they are so inclined to one side such as concept-oriented frameworks or technology-oriented ones. They lack universal and wide-ranging features. This paper presents a comprehensive methodology to accumulate knowledge capital on DW via a properly grained hypermedia model. The methodology consists of three phases: knowledge requirement elicitation, hypermedia modeling, and system implementation. A real-life case for medical DW development is presented to demonstrate the usefulness of the proposed methodology. This methodology is effective when an organization accumulates knowledge assets to put the corporate e-biz or cre-biz strategy into practice.
