  • Requirements are very important to model software architecture. Requirements are divided into functional and quality requirements. Functional requirements are pinpointed subsystems and components. Quality requirements affect the structure of architecture. Thus requirements are essential to understand clearly in order to design software architecture. This paper focuses on a quantitative approach to requirements analysis for modeling architectures. In our proposal, functional requirements are quantified through calculating each priority of components. Quality requirements are quantified through calculating the correlation degree between components and quality attributes. The proposed method is implemented by DRAMA (Domain Requirements Analysis for Modeling Architectures), which fully supports our approach and are developed in Java environments. Our proposal is validated to apply some industrial examples.

  • The network security encryption type is divided into two, one is point-to-point, second method is link type. The level of security quality attributes are a system security quality requirements in a networked environment. Quality attributes can be observed and should be able to be measured. If the quality requirements can be presented as exact figures, quality requirements are defined specifically setting quality objectives. Functional requirements in the quality attribute is a requirement for a service function which can be obtained through the encryption. Non-functional requirements are requirements of the service quality that can be obtained through the encryption. Encryption quality evaluation system proposed in this study is to derive functional requirements and non-functional requirements 2 groups. Of the calculating measure of the evaluation index in the same category, the associated indication of the quality measure of each surface should be created. The quality matrix uses 2-factor analysis of the evaluation for the associated surface quality measurements. The quality requirements are calculated based on two different functional requirements and non-functional requirements. The results are calculated by analyzing the trend of the average value assessment. When used this way, it is possible to configure the network security encryption based on quality management.

  • The quality of requirements is one of the key factors in the success of a project. One of the studies on successful projects is the reuse of requirements. However, the rate of failed projects is about 70%, and these projects often fail because of improper requirements. The current techniques for software reuse may not perform requirement engineering appropriately or develop requirements having good characteristics. In order to improve this situation, we propose a model for reusing requirements. We expect that our model will contribute toward increasing project productivity using requirement reuse in existing projects, and reusing requirements that have good quality.

  • 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.

  • 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.

  • This paper describes the method of establishing efficient system for the control of quality records. To establish the best control system of quality records, the organization must not only understand ISO Code requirements for quality record complectly but also identify the documents to be controlled as a quality records correctly. In addition, when establishing the system, the organization must absolutely consider the fact that quality records shall be maintained to demonstrate conformance to specified requirements and the effective operation of the quality system. This will provide the guidance which need to establish the system for quality control to the organization which produces documents in accordance with ISO Code requirements.

  • Kano distinguishes between three types of quality requirement which influence customer satisfaction in different ways when met in his model and proposes fulfilling attractive requirements leads to more than proportional satisfaction. However each of attractive requirements do not influence customer satisfaction equally Thus, this study will present a model using AHP(Analysis Hierarchy Process) which priorities over quality requirements objectively
