Most manufacturing companies participate in various types of active collaboration to enhance competitive advantages in their arenas. In this paper, we introduce a data warehouse system that is designed for manufacturing collaboration. Just as enterprise information systems, collaboration support systems also need functions of performance measurement and monitoring. For this reason, we devise a new approach to measuring and evaluating performance of manufacturing collaboration. Specifically, we first present a concept of process warehouses for manufacturing collaboration. Next, we design a data schema of collaborative process warehouses to store and monitor collaboration performances. Finally, we implement a prototype system to support performance management of manufacturing collaboration. The proposed system can be used to effectively maintain and continuously improve collaboration in manufacturing industry.

Hazard analysis identifies probability to hazard occurrence and its potential impact on business processes operated in organizations. This paper illustrates a quantitative approach of hazard analysis of information systems by measuring the degree of hazard to information systems using probabilistic risk analysis and activity based costing technique. Specifically the research model projects probability of occurrence by PRA and economic loss by ABC under each identified hazard. To verify the model, each computerized subsystem which is called a business process and hazards occurred on information systems are gathered through one private organization. The loss impact of a hazard occurrence is produced by multiplying probability by the economic loss.

Business Information Systems are strategic applications to achieve companies' goals and innovation. This idea make companies invest their time and budget in the Information Systems. However, it is difficult to forecast effects of the investment in Information Systems and it causes hesitation of making decision. Thus, I researched a case so that I could forecast the effect of the information systems using AHP(analytic hierarchical process). In this study, I approached this matter with three views such as intelligence(review of prior literature), design(methodology development), and application. This study is significant in terms of practicality rather than theoretical dimension. Particularly, I suggested a way of quantifying in monetary value the quality aspects through inverting qualitative facts to quantitative facts and calculated the investment feasibility with it.

Purpose This paper attempts to identify items for improving the usage of PLM(Product Lifecycle Management) systems and suggests ways to prioritize improvement items on the basis of importance. It also tries to find out differences in the importance of improvement items due to the company size, the industry, the job, or the PLM solution. Design/methodology/approach Through a survey from participants to a PLM System Conference, data were collected from a sample of 181 users who had the previous experience in using a PLM system. In order to figure out the differences in the importance among user groups, the F-test with the Scheffe test as a post-hoc analysis was used in case of equal variances and the Welch test with the Dunnett T3 test was used in case of unequal variances. Findings This study sorted out 25 improvement ideas according to their importance assessed by the PLM system users. The top five ideas are improving data consistency, error minimization, fast system response time, enhancing user recognition, and business process improvement. The support group puts higher importance than the general user group in data consistency, fast system response time, enhancing user recognition, business process improvement, dedicated team for data consistency, continuous support from management, hardware performance upgrade, output linkage to other systems, and shortening problem solving duration. The largest company group attaches significantly higher weights than the smallest company group to data consistency, error minimization, fast system response time, business process improvement, dedicated team for data consistency, security with proper access management, output linkage to other systems, and better user interface.

Proposed in this paper is a standard-compliant business process modeling tool which is based on the UML(Unified Modeling Language) activity diagram and produces an XPDL(XML Process Definition Language) file as an output. The XPDL is a standard process definition exchange format by WfMC (Workflow Management Coalition). To develop an UML/XPDL-based modeling tool, the mapping of modeling elements between activity diagram and XPDL format is conducted after the detailed analysis of each modeling specification. As a result of this mapping, it is revealed that modeling elements of each activity diagram and XPDL must be expanded. So new modeling elements are identified and added to each specification. Based on this mapping, the prototype system is developed, and the usefulness of the developed system is shown through the case study.

Players of construction projects proceed with each work process by information gathering, modification and communication. Due to the complex and long-span lifecycle projects increased, it became more important to grasp this mechanism for the successful project performance in construction project. Hence, most project information management systems or knowledge management systems equip information retrieval system. There are two logic to infer the meaning of retrieval target; inductive reasoning and deductive reasoning. The former is based on metadata explaining the target and the later is based on relation between data. To infer the information flow, it is necessary to define the correlation between players and work processes. However, most established information retrieval systems are based on index search system and it is not focused on correlation between data but data itself. Thus, this research aims to research on process of information flow retrieval system for large-scale construction projects.

Recently, ERP system is used as a important tool of management innovation for enterprise's survival and development. It is very important to recognize how much influence to organizational performance through ERP system implementation. The purpose of this study is to find out the impact of environmental, organizational, information systems characteristics on successful implementation of ERP systems in Korean SMEs(Small and Medium Enterprises). From previous researches on ERP adoption and implementation, 7 independent variables (competitiveness, government support, top management support, process innovation, project management, IS maturity, and ERP customizing), and 1 dependent variables (successful implementation of ERP systems) are identified. 3 questionnaires were removed from the study because of missing or inappropriate responses, and final samples are 91 SMEs. The results of hypothesis testing show that determinants of successful implementation of ERP systems are top management support and IS maturity. Five variables such as competitiveness, government support, process innovation, project management, and ERP customizing do not significantly influence to successful implementation of ERP systems. The contribution of this study is that it provides an empirical evidence of the causal relationship between ERP adoption factor and ERP success. This study showed that top management support and IS maturity are essential to accomplish successful ERP implementation for SMEs.

Many 6-sigma innovation companies are obtaining ISO9000 series or ISO/TS16949 certifications. However, not many of them have considered the integrated management of ISO/TS16949 at the time of 6-sigma introduction. ISO/TS16949 focuses on the process of an overall company. In particular, APQP (Advanced Product Quality Planning) requires that from the beginning all the planning should have a clear quality planning business process. Each company can decide the best course of action to suit its individual needs. Lean DFSS in 6-sigma offers the concrete development steps of the product development process. And if analyses of Input, Output, Target, Process, KSF, KPI, and FMEA is done in each process and clearly defined in APQP, mutual organic and effective systems can be initially achieved.

The purpose of this study is to investigate COVID-19's impact on firm survival, as well as the management accounting system's role in adjusting operation efficiency for business survival. Two sets of data comprising small enterprises in the service sector were used. The first business group serves customers who have changed their lifestyle to a new normal. The second business group serves customers who are affected by social distancing measures. The data was collected based on an in-depth interview method. The data was then evaluated using content analysis and analytic comparison. The results show that the COVID-19 situation positively impacts the business survival of the service businesses group that serves customers who have changed lifestyles. However, COVID-19 has a negative effect on the survival of service business groups that serve customers affected by social distancing measures. In addition, the management accounting used during COVID-19, small enterprises have analyzed the operating environment and used the information stored in the database to determine goals for the operation. This study provides comprehensive economic effects and the utilization of management accounting systems. The accounting systems helped to decide to adjust the operation process during the quick changing of the environment of the small enterprise in the service sector.
