  • More than 50% of defects and errors in the software development projects are related to the requirements[14]. But the development methodologies can not provide enough supports to the requirements management and changes. In the real world, the requirements keep changing as the requirements at the early development phase are usually incomplete, the developer′s understanding of the problem will be constantly changed during the software process, and new requirements may emerge with the organizational and environmental changes. In this paper, a requirements management process that can be integrated into the development methodologies is proposed to extend the requirements management over the whole development life-cycle and to support the requirements changes at the design/implementation/test phases. To evaluate the proposed process, it was compared to the existing requirements managements processes and models, and examined through a integration test with a widely used development methodology "MaRMI" to show the expected improvements at each development phase.

  • 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.

  • In Weapons acquisition process, if the requirements are not clear, it leads to confusion and conflict in business. In the development of next-generation weapons, to define and derive requirements has to start from decision of operational concept. It is difficult task and has many uncertainties. This paper has goal about development of knowledge acquisition process that derive military operational scenario-based requirements acquisition process and framework that classify and save the derived requirements for next project. That framework can generate new class and category, also suggest that verification of requirements. It help to derive and manage the requirements, and make it easy to grasp the requirements. Accordingly, it can help make military requirement plan and weapon acquisition process.

  • Requirements definition, which determines a project baseline, has a strong impact on the success of a project. However, since in-depth requirements are gradually revealed through the requirements definition process, the requirements definition is not a straight forward process and often falls into disorder. Thus project management standpoints are critical for the success of the requirements definition. In this paper, we present a framework and mechanisms of communication-centered project management, which controls the requirements definition process based on the situation of communication-oriented activities among stakeholders. In addition, we present a communication-centered project plan with a planning method. The project plan, which represents a time schedule of requirements definition activities, is made by a simulation-optimization algorithm using a stakeholder matrix showing the relations of requirements domains and relevant stakeholders. The effectiveness and the significance of communication-centered project management at the requirements definition phase are demonstrated by numerical examples.

  • Development of human-system interfaces (HSI) supporting the interaction between human and automation-based systems, particularly safety-critical sociotechnial systems, entails a wide range of design and evaluation problems. To help HSI designers deal with these problems, many methodologies from traditional human-computer interaction, software engineering, and systems engineering have been applied; however, they have been proved inadequate to develop cognitively well engineered HSI. This paper takes a viewpoint that HSI development is itself a cognitive process consisting of various decision making and problem solving activities and then proposes a design requirements-driven process for developing HSI. High-level design problems and their corresponding design requirements for visual information display are explained to clarify the concept of design requirements. Lastly, conceptual design of software system to support the requirements-driven process and designers' knowledge management is described.

  • 현재 소프트웨어 개발 공정이 복잡해짐에 따라 개발하는 소프트웨어의 요구사항 역시 복잡해지고 있으며 요구사항 관리에 많은 노력이 소요되고 있다. 그러나 소프트웨어의 요구사항을 처음부터 모두 정의하는 것은 사실상 불가능하며, 개발이 진행되면서 환경은 변하기 마련이다. 또한 요구사항 변경은 개발보다 많은 비용이 소요되므로 체계적인 변경 관리를 통해 변경에 민첩하게 대응하고 관리되어야 한다. 본 논문에서는 소프트웨어 프로덕트 라인에서 요구사항 변경 관리 프로세스를 기반으로 체계적인 요구사항 변경 관리 방법을 제시한다. 소프트웨어 프로덕트 라인(software product lines)에서 어플리케이션의 요구사항은 도메인 요구사항과 밀접하게 관련되어 있으므로 어플리케이션 공학(application engineering) 단계에서 요구사항 변경이 발생했을 경우 도메인 공학(domain engineering) 단계를 이용하여 변경을 분석하고 관리하는 방법을 제시한다. 이러한 일관된 변경 관리를 통해 변경 범위를 분석하고, 변경 대처방안을 제시함으로써 변경 처리 결정을 내리는데 도움을 주며 한번 요청된 변경이 완벽하게 처리되도록 도와주어 같은 변경의 반복 요청을 막을 수 있기 때문에 잠재된 변경 비용을 절약할 수 있다.

  • The work environment of locomotive cabs has long been an important issue in the design of railload systems since it is quite critical in terms of system's operational safety. It is getting more attention as the running speed of the trains goes up these days. To this end, this paper describes how to systematically construct a DB for the requirements set in the course of the improvement process for the aforementioned cab work environment. As a solution approach, we have adopted the requirement architecture concept to cover the whole activities required to do such as in requirements generation, DB construction, change management, and traceability management. Specifically, based on the requirement architecture framework a requirement process to collect requirements for improvement is discussed, and the guide lines are suggested for verification and validation of the developed requirements. In addition, a base schema and requirements templates are developed, which will be used in generating requirements and constructing a DB. Finally, it is demonstrated how the requirements DB for locomotive cabs can be constructed using a computer-aided tool in an integrated fashion.

  • For the success of system development, it is necessary to systematically manage the requirements that are the basis of system development and its verification results. In order to follow the principles of SE(Systems Engineering)-based V&V(Verification&Validation) process, requirements can be managed by securing the requirements and their establishments, design compliances, and verification compliances according to the system development lifecycle. Especially, in a large-complex system research and development project, such as a space launch vehicle development project, many participants establish, verify, and validate numerous requirements together during the project. Therefore, logical and systematic requirements management, including guarantee of data integrity, change history, and traceability, is very important for multiple participants to utilize numerous requirements together without errors. This paper introduces the practical requirements and verification management for the requirements-based development process in the space launch vehicle development project.

  • Requirements engineering is an important phase in a system's life cycle. It is important to perform it correctly. The increasing complexity of systems makes requirements engineering activities more difficult. Non-functional requirements are drivers to emerge how much emergent system properties to aim for success. All functional requirements may be satifsfied, but if the level of desired non-functional requirements are overlooked, the system development will fail. There is growing awareness of the importance of defining non-functional requirements early in the process among the requirements engineering (RE) community. This paper propses a SysML based approach for non-functional requirements to identify and specify very early in the process or requirements engineering.

  • Process of thinking on the form in product design includes the process in which unclear requirements are transformed into defined concepts, and the process in which the design as a form conforming to the concepts in conc1uded.(The former is called fconceptualizationJ which deals with abstract matters, and the latter "manipulation of the formJ which deals with more embodied matters) In conceptualization process the operation which transform the diverse requirements in the initial phase of de\ulcornersign to related linguistic expressions or to an image that directly suggests the form is executed. In the process of manipulation of the form the transformation to design as the description of relationships between the formal elements of the design solution resulted from the transformed requirements. It is the job of selecting the most suitable formal elements, balancing the relationships between them, out 01 the possibilities that reside in the individual attributes of formal elements, and finally leading to the design as the end solution. This writing focuses down to the wilfulness and ambiguity of design, and the diversity of design solution after the requirements, formal elements, and the process of relating the formal attributes to each other is built up the two phases.ases.
