요구사항은 아키텍처를 생성할 때 매우 중요한 요소로써 기능 요구사항과 품질 요구사항으로 구분된다. 기능 요구사항은 하위시스템 또는 컴포넌트 생성에 영향을 미치고 품질 요구사항은 아키텍처의 구조를 결정하는데 영향을 준다. 이와 같이 요구 사항은 아키텍처 설계에 중요한 영향을 끼치기 때문에 아키텍처 설계를 위해서는 요구사항에 대한 명확한 이해가 필요하다. 본 논문에서는 요구사항에 대한 명확한 이해를 돕기 위해 요구사항을 정량화하는 방법을 제안한다. 기능 요구사항은 기능적인 우선순위 계산을 통해 컴포넌트를 정량화하고 품질 요구사항은 정량화된 컴포넌트와 품질 속성의 연관성 계산을 통해 정량화한다. 제안된 방법은 DRAMA (Domain Requirements Analysis for Modeling Architectures) 도구를 통해 구현되었으며, 요구사항의 정량화 방법을 실 예제에 적용해본 결과를 소개한다.

AIS(Automatic Identification System) provides navigational information including identification, position, a ship's course and status to ground and other vessels. To obtain AIS Marine Equipment Approval Service, various requirements are required and meet the requirements International Standards. However, most of the requirements are to identify essential functions, response time, hardware requirements, and communication protocols of AIS. The requirements for the quality of SW are not sufficient or detailed, and the weight is relatively low. As role of SW grows and types become more diverse, AIS SW quality inspection is essential. In this paper, We apply eight-quality characteristics of ISO/IEC 25023 standard to improve SW coverage quality of AIS. Suggest additional AIS SW requirements based on the eight quality characteristics of ISO/IEC 25023 standard.

네트워크 보안 암호화 방식은 단대단 암호화 방식과 링크간 암호화 방식으로 구분된다. 네트워크 환경에서 보안 품질요구사항 이란 시스템이 제공해야 할 보안품질 속성의 수준이다. 품질속성은 관찰할 수 있고 측정할 수 있어야 하기 때문에 품질 요구사항도 가능하면 정확한 수치로 제시되어야 한다. 품질 요구사항이 정의되어야 구체적 품질 관리 목표가 설정된다. 품질속성에서 기능적 요구사항은 암호화를 통해 얻을 수 있는 서비스 기능에 대한 요구조건이다. 비 기능적 요구사항은 암호화를 통해 얻을 수 있는 서비스의 품질 요구조건이다. 본 연구에서 제안하는 암호화 품질 평가체계는 기능적 요구사항과 비 기능적 요구사항 2개영역으로 도출한다. 평가지표의 동일 분류내 척도를 산출한 후 각 지표의 품질 측정값에 대한 연계지표를 작성한다. 품질평가 매트릭스는 품질측정 값에 대한 연계지표 분석용 2-factor 평가로서 기능적 요구사항과 비기능적 요구사항 두 가지 기준으로 평균치를 산출 한다. 산출결과는 추세를 분석하여 종합 평가가 가능하도록 한다. 이와같은 방식을 적용할 경우 네트워크 보안 암호화 품질평가의 기반을 구성할 수 있다.

In this paper, the trend of quality management system that suppliers in the automotive industry are adopting, the classification system of suppliers and car manufacturers requirements for quality are described. Due to the complexity of the requirements for quality, the introduction of an active quality management system which can meet all conditions is a difficult task. Thus, to cope with this difficulty, this paper shows the optimal requirements that suppliers have to consider when they are introducing quality management system and the discriminated strategies to assure parts quality by supplier model.

The famous US quality management expert J. M. Juran pointed out on the American Quality Congress of ASQC in 1994, that the 20th century is a century of productive force and the 21st century would be a century of quality. In the past dozens of years; science and technology have made rapid progress. Take electronic products for example, the non-conformity rate has dropped from 1%($10^{-2}$) and 1%($10^{-3}$) to ppm (parts per million, $10^{-6}$), even to ppb (parts per billion, $10^{-9}$). Such a low non-conformity rate can be called the super strict quality requirements of products of the $21^{st}$ Century. Super strict quality requirements can cause a series of new changes: Therefore, super strict quality requirements are unavoidable to produce significant influences to the industry of the $21^{st}$ century. This paper analyzed these influences and pointed out that which quality sciences must be paid attention to first.

Kano(1984) distinguishes five types of Quality requirement which influence customer satisfaction; Attractive, One-dimensional, Must-be, Indifferent, Reverse Quality element. Attractive requirements lead more than proportional satisfaction. Attractive Quality requirements are the key factors of order winner and the sources of customer delight. Attractive requirements do not influence customer satisfaction equally. This study presents Kano's model using AHP(Analysis Hierarchy Process) for the priorities of attractive Quality requirements.

ISO 9000 family of standards are consisted of four international standards for implementing and operating effective quality management systems. They are interrelated and together form a coherent set of quality management system standards. ISO 9000, one of the standards, contains quality management principles, which is asserted to form the basis of other standards within the family. ISO 9001 is another standard within the family and contains requirements for quality management systems. This paper shows how the quality management principles of ISO 9000 are related with the requirements of ISO 9001.

Client requirements is a concept with increasing interest in relation to several outcomes of companies, and in particular, in the event of apartment project that takes large share in the domestic construction industry, diverse angle of survey is performed to discover the client requirements and reflect them to the project to improve the quality. For this purpose, it is required to learn the client requirements and apply it in the apartment project, and the QFD (Quality Function Deployment) linked ROQ (Return On Quality) is a technique used in the manufacturing that surveys the client requirements to improve the customer satisfaction, and apply it to the quality improvement program to improve the profitability in this process. In this study, through the application of the ROQ process, the plan to improve the apartment quality management is presented. For this purpose, the consumer interview survey, FGI (focus group interview) survey and the client requirements are analyzed, and thereafter, through the interview with the specialist, the quality improvement program that enables the application to the product development of new apartment product is established. Through this process, the new apartment quality management improvement plan is presented.

In the current software project, it is still very difficult to extract and define clear requirements in the requirement engineering. Informal requirements documents based on natural language can be interpreted in different meanings depending on the degree of understanding or maturity level of the requirements analyst. Also, Furthermore, as the project progresses, requirements continue to change from the customer. This change in requirements is a catastrophic failure from a management perspective in software projects. In the situation of frequent requirements changes, a current issue of requirements engineering area is how to make clear requirements with unclear and ambigousrequirements. To solve this problem, we propose to extract and redefine clear requirements by incorporating Design Thinking methodologies into requirements engineering. We expect to have higher possibilities to improve software quality by redefining requirements that are ambiously and unclearly defined.

The purpose of this study is to present an evaluation model to measure the clarification level of stakeholder requirements of public sector software projects in the Republic of Korea. We tried to grasp the quality of proposal request through evaluation model. It also examines the impact of the level of stakeholder requirements on the level of system requirements. To do this, we analyzed existing research models and related standards related to business requirements and stakeholder requirements, and constructed evaluation models for the system operation concept documents in the ISO/IEC/IEEE 29148. The system operation concept document is a document prepared by organizing the requirements of stakeholders in the organization and sharing the intention of the organization. The evaluation model proposed in this study focuses on evaluating whether the contents related to the system operation concept are faithfully written in the request for proposal. The evaluation items consisted of three items: 'organization status', 'desired changes', and 'operational constraints'. The sample extracted 217 RFPs in the national procurement system. As a result of the analysis, the evaluation model proved to be valid and the internal consistency was maintained. The level of system operation concept was very low, and it was also found to affect the quality of system requirements. It is more important to clearly write stakeholders' requirements than the functional requirements. we propose a news classification methods for sentiment analysis that is effective for bankruptcy prediction model.
