  • Consider a stuffing process where sausage-casings are filled with sausage-kneading. One of the most important factors in the stuffing process is weights of stuffed sausages. Sausages weighting above the specified limit are sold in a regular market price for a fixed price, and underfilled sausages are reworked at the expense of reprocessing cost. In this paper, the sausage stuffing process is inspected for improving productivity and quality levels. Several statistical process control tools are suggested by using real data obtained from a Korean Vienna sausage company.

  • Process control and autonomous safety control by applying PSM(Process Safety Management) method using AHP(Analytic Hierarchy Process) and to development of PSIM(Process Safety Information Management) evaluation method in the construction. The reason why PSIM method should be quantitative and substantial progress is because it contributes Korean constructing companies to enhancing their safety control ability and to taking an equal stance just like developed countries, thereby strengthening their competitive edges.

  • This study identifies the current status of hanok design process and required design information through individual survey and interview with hanok architects and builders to suggest a proposal. Current design system turns out to be a common design process not reflecting hanok's unique mechanism of production. The proposal consists of the alternative design process, 'Initial survey / Site and structural planning / Spatial layout and form / Openings, interior and exterior elements design / Detail design', containing the specialty of hanok's mechanism, and the lists of design information required in its each stage. The proposed design process also emphasizes the significance of consultation in a way of designing coordination, and classifies the specific contents for each consultation moments. The study is expected to contribute for architects including the group who are not specialized in hanok to improve the architectural quality by following the systematic design process. Also the design system provides a framework to organize the vast range of design information being recently developed in the technique-oriented area.

  • The control chart is widely used tool for monitoring of the process. This paper deals with an interpretation of the process capability index(PCI) and process performance index(PPI) when the control chart is used for monitoring of the process. The main difference between the PCI and PPI is how we did estimate the process deviation. The PCI uses the within process variation and the PPI uses the total process variation, which is conceptually defined as sum of between process variation and within process variation. Easy interpretations of the PCI and PPI for field engineers are described. And some new approaches to interpretation of the process capability and performance index may be useful in early stabilization of new process.

  • This study was tried for the improvement of software process ability of the software firms, and analyzed empirically the impact that a software process infrastructure level influences on the software process level and process performance. The questionnaire were developed and data were collected from the process improvement correspondences or project quality managers of the 78 software firms. The result was shown that management-organization infrastructure was composed of software process improvement organization's role and activity, process standard and education, management system and supporting, management guides and procedures. And organization's standard development procedure or criteria, process asset, process support tools were included in technical infrastructure. This study provides that some components of software process infrastructure had an significant influence on the process level, process infrastructure management level, and software process performance.

  • Most organizations adopt a process-based approach to manage their operations and now business process management(BPM) is a well-established concept. Because ISO 9001:2000 has been influenced by BPR and it also emphasizes process based. BPM can get together with ISO 9001:2000. Korea Institute of Science and Technology Information has taken ISO 9001:2000 certificate in November 11, 2003 and now implements quality management systems based on BPMS. We call it KQMS(KISTI Quality Management System). KQMS based on BPMS is a new example in field of ISO quality management and is expected to support process management well.

  • There is no overdoing of enforcement of the importance of strategical mind which indicates future direction when management environment around organizations are variously changing. This document describers preceding and comparison research about competition strategy, competitive advantage and IT centered on organizations' common issue "Guarantee of Continuous Competitive Advantage" and researched various factors to determined if Information Technology is functioning properly through the cases of excellent organizations operating continuous competitive advantage Continuous competitive advantage's source is evaluating positively about resource based view which is described by innovation of business process. However, reality of operating continuous competitive advantage with difficult imitation of business process' "Time" "Complexity" is insufficient. Confirm how continuous competitive advantage is operated in reality by accepting easy application of "Simple Concise" business process. Confirm existence of information technology capability creating difficult imitation is functioning as a source of continuous competitive advantage, not Information Technology resource supporting business process.

  • Evolutionary acquisition is an alternative to the grand design acquisition approaches. It has activities to make it possible to develop quickly and respond flexibly to changing customer needs and technological opportunities. The Ministry of Defense adopted an evolutionary strategy to acquire defense information systems. but it does not work well always. We look at problems from aspects of acquisition system and project management. We benchmark successful cases for evolutionary acquisition strategy in the DoD, the pubic and the private sector. We suggest an evolutionary strategy for defense information systems. The evolutionary strategy in this study includes an evolutionary acquisition framework, an evolutionary acquisition process, and an evolutionary acquisition guideline for defense information systems. The evolutionary strategy can help to implement evolutionary acquisition process for defense information system, and the process can increase the success rate of projects.
