  • Purpose: For effective quality assurance activities, BOM-based quality assurance method is presented. This study introduces various BOM conversions such as Q-BOM, T-BOM, and S-BOM based on M-BOM structure. Methods: Product quality control via Q-BOM manages inspection/audit information, overall supply-chain of product, part requirements, and inventory status. T-BOM manages part traceability, and S-BOM enables statistical control over key process and parts at various hierarchy levels. Results: Quality plan template was developed based on the study results of BOM system including Q-BOM, T-BOM, and S-BOM. Conclusion: Through BOM(Q-BOM, T-BOM, and S-BOM) study and development of quality plan template, more systematic and comprehensive quality management plan is achieved.

  • Developing a component-based software requires verified and standardized software components. This paper presents a component quality management (CQM) process. The process was developed and applied to the government-sponsored trial projects that developed software components. The process is composed of four phases:quality specification, quality planning, quality control, and quality evaluation. With this process, we can establish quality goals and focus our efforts on the activities to achieve the goals. A component quality model is also suggested to transform the implicit quality requirements into the measurable quality goals and to be used for the basis when we evaluate the quality of software components against the quality goals.

  • Ever since the ISO (International Organization for Standardization) established the ISO 9000 Family standard in 1987, many countries have selected this as their national standard and have provided support for its implementation and conducted assessment activities on the results of its implementation. Likewise, certification assessment was first begun in Korea in 1994, with the result that over 7,600 certificates have been issued to domestic enterprises during the past 5 years or so. This is significant not only in the remarkable growth rate in terms of quantity but also in the fact that it has made possible the establishment of a quality system that meets international standards among Korean enterprises. In this article, it will briefly introduce the establishment and certification of the ISO quality system for those organizations that are complying with the quality system as a part of the process of strengthening their quality competitiveness. For those organizations that have already established the quality system and implemented it for years, we will show the direction for continuous quality improvement in order for these organizations not only to fulfill the requirements but to maintain the superiority of the quality system and their management quality. In addition, it will show what preparations are necessary for organizations and certification bodies in order to expand a manufacturing process-oriented quality system to one that is geared to the total management quality.

  • The construction industry consists of various and massive architectural information as an architectural process includes a variety of design stages with cooperation of many disciplines. Particularly, architectural information is generated and managed through the life cycle of a building, from conceptual design stage to the construction and maintenance. A Building Information Model (BIM) serves as a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle from inception onward. BIM technology accomplished quantitative development being utilized in various disciplines. However, it is necessary to develop environment and requirement for qualitative improvement of BIM based project. Particularly, requirement is very important for architectural design evaluations. The purpose of this study is to develop and apply of quality control check-list for improving the quality of architectural design in BIM environments. To achieve this purpose, the authors have investigated case study for open BIM data quality control (software, guideline and application case) and classified quality control targets according to physical/logical quality control and data quality. In addition, the authors have defined open BIM based quality control process and developed quality control check-list. Finally, the authors have developed automatic quality check system using requirements for efficient quality control based on open BIM.

  • As growth of the web-based applications, the requirements of the users who have been very familiar to the web-based user interfaces and customer-oriented services on the Internet would become more knowledge-intensive and higher technology involved in a more convenient and polite way of service delivery. Therefore, the service quality of information system department should be considered as a very important factor influencing success of information systems. The objective of this study is to provide the relationship between service quality of IS department and its impacts such as use, user satisfaction and job performance. For this purpose, we provide a research model for it and test it empirically for the users of the corporate portal in one of main telecommunication service providers in Korea. In result, our model with satisfiable validity and reliability shows not only importance of IS departments' service quality but also two-faced characteristics of service quality. That is, while technical competence which means with knowledge and expertise of IS department staffs is more related with user satisfaction on information systems, personal service which means the way and manner of service delivery is more related with use of it.

  • In this article, an in-depth review is presented to explain the present status of QC and QA for air quality monitoring, especially with respect to a few pollutants of which measurement requires high standard such as VOC and heavy metals. Upon reviewing the reported results of various studies conducted previously, we attempted to suggest a future direction of QC and QA for the acquisition of the high quality data in the air quality monitoring.

  • As more and more companies pursue ISO 9000 certification, the adaptation of ISO 9000 has brought about some significant positive effects to domestic quality systems However, somenegative results occurred in domestic industries rushing to fulfill the requirements of these new quality systems. The primary objective of this research is to provide the efficient implemen tation process of ISO 9000 certification on the basis of total quality management concerning with ISO/ DIS 9000:2000, ISO/ DIS 9001:2000, ISO/DIS 9004:2000. this study has been conducted using the data collected from 325 Korean small and medium manufacturing companies which registered ISO 9000 certification in March 2000. The first, the adoption of a quality manage ment system needs to be a strategic decision of the organization. The design period of the adoption of a quality management system is influenced by the size of the organization, the products process, KS certification, the rate of management.

  • In accordance with the growing importance of software in computer systems, software quality and performance has become a hot issue in all computer-related fields and businesses. But the measurement and evaluation of software quality still poses a problem, due to the different viewpoints of software developers and users. This study attempts to combine the external characteristics of quality representing the viewpoint of users, and the internal characteristics representing the viewpoint of developers of quality. In order to do this, this study provides multiple models which select the appropriate internal characteristics which reflect user requirements from earlier phases of development. The goal of this study is to enhance the applicability of 40 internal characteristics of ISO 9126 to the models.

  • CMMI(Capability Maturity Model Integration) has been recognized as a critical method to validate the competitiveness of software development organization since its introduction. CMMI imposes additional requirements on the software development organization which has been established and certified to the ISO 9001 quality management system. This paper reviews the similarities and differences between CMMI and ISO 9001. This paper also examines what ate required to deploy the CMMI on the aircraft software development organization which has been certified to ISO 9001. The results of this study will help software development organization to provide the direction for implementing CMMI. Some suggestions are presented to identify and strengthen the weak portion of the software process quality management system.
