One of the major applications of CRM systems is to integrate and automate selling processes. CRM systems provide sales people with tools and data sources they need to reengineer their selling processes. In the industry where sales are traditionally based on personal relationships and the use of the CRM systems is voluntary, the installation of technical solutions does not guarantee Selling Process Reengineering (SPR). The objective of this study is to investigate (1) organizational factors that influence CRM use by sales personnel; and (2) the mediation effect of CRM system use on SPR success when system use and process reengineering are voluntary rather than institutional. Understanding the determinants of voluntary CRM system use and SPR success provide valuable guidance for managers. Managers can benefit from this study by focusing on improving the factors that affect voluntary CRM system use and SPR success.

The various software engineering techniques have been come out in order to cope with the software crisis since 1980's. These days the software Engineering has focused on the process of software development which is the guide for a qualify and productive improvement of software. But, most of the methodologies assume that a new system will be constructed and reused in the future. these do not support how we reuse legacy system's resources and construct a new system efficiently. In this paper, we present an efficient Reengineering Process for legacy system evolutions, RUP+re, which extends and customizes RUP. RUP+re consists of Reverse Engineering Workflow, Transformation Workflow and Evolution Workflow based on Small-h model. We describe RUP+re's workflows with their own detail steps and verify the process through the case study practivally. So, we provide efficient guidelines to the software Reengineering process construction which evolutes the resources of a legacy system.

It is certain that EC(Electronic Commerce) applying the internet will be activated in the knowledge society of 21 century based on IT(Information Technology). Though this change of social environment helps the useful information resource available to expand, it looks like that the rapid inclease in lots of information to gather makes colleges, reseach laboratories and public institutions to spend more man power and money on work of book purchases than before and now. Therefore the most urgent part for the business process reengineering in work of information service center is the business of book purchases. The business of book purchases is the core part in organizations and facilities. It should construct the books which the organigation and facility need in the most economical and efficient way within the range of physically receptive capacity with the limited budget. These organigations and facilities have to establish the policy of the book stock which they should possess and also librarians should endeavour to configure the kernel book stock constantly. I assert that they need to ensure a specialty with the improvement of business process accompanying choosing and purchasing the books. Especially, in a case of purchasing foreign books by request of members like professors, students, researcher and so on they have to replace the business of book purchase using agency with direct dealing using EC. This Business Process Reengineering will cut down on expenses, offer the transparency of book purchases and also give the users confidence. Moreover the Business Process Reengineering make it possible to build well constructed main books and information resource. The people in charge are enabled to acquire the knowledge of subjects with contiuous search for books of a spcial area and self-study. These experts in work will raise the quality of information service. Information service center will be the core in the 21c knowledge industry. To streng then value of it, efficiently run it and control it the existing business of book purchasing should be replace with direct dealing using EC applying the internet.

BPR(Business Process Reengineering), a radical improvement approach of business process, has been paying attention, and work-flow management and automation has been concentrated on progress velocity of business process and productivity of engineers. In software engineering, software process engineering which focus to process begin to be watched, and for the purpose of software productivity and quality progress and reduction of development term, study on SPR(Software Process Reengineering) is being progressed. In this paper, made workflow analysis and design method for construction of work-flow management system of software process to stand firm process reengineering methodology. In other words, we studied modeling process methods for SPR process, and software process structure and workflow analysis method which construct software process workflow model and specification definition method of workflow software.

Northeast Asia Nations introduced each single window system for simplifying the customs clearance procedures in order to prevent the rekeying the customs and trade-related data. A single window is a means for enabling users to complete all the necessary import/export procedures in a single input and by single transmission by linking the related system. WCO recommends CDM, UCR, ACI that completed by WCO's own projects for assist to establish the single window for customs clearance. Northeast Asia Nations such as Korea, China, Taiwan, Japan undertook trade process reengineering for introducing single window for customs clearance. Korea and Japan introduced a e-customs systems as a good single window system. The purpose of this paper is to contribute to construction of the efficient single window system for customs clearance by studying e-customs cases in Northeast Asia Nations.

Business process reengineering(BPR) aims at a radical redesign of our business processes in order to achieve dramatic improvements in their performance. However, the fact that many BPR projects have failed hesitates the companies who have started to use BPR or who are planning to do so. Implementing a radical plan from a cross-functional perspective needs a more careful consideration of process vision, preventive measures and contingency plan. Our research suggests to use a visual decision making process (VDMP) in the development of a process vision and implementation plan. A BPR project of Carlson School of Management (CSOM) at the University of Minnesota is illustrated to show our suggested methodology.

A web-based information system, that is a dominant type of information systems, suffers from the “web crisis” in development and maintenance of the system. To cope with the problem, a technology of reengineering to web-based business process, which is one of web engineering, is strongly needed. In this paper, we propose a BPN(Business Process Net) model and reengineering guides along with an application example, which are used for modeling web-based business processes and migrating to web-based information system. BPN model is a type of not only a Beta-distributed stochastics Petri net, but also an executable Activity diagram. BPN is modeled by using the Use Case analysis method and the Beta-distribution. The later is used for the purpose of modeling the uncertainty of execution time and cost of a business process. BPN model and reengineering heuristics might be used as a formal common model for business process specification languages, and analysis and design method for Web-based Information system, respectively.

Complicated business logic makes program complexity more complicated. It's inevitable that the program must undergo reengineering processes all the way of in its lifetime. Hot spot analysis that has diverse purposes is getting an important question more and more. As a rule, reengineering process is done by UML model-based approach to analyze the legacy system. The smallest fragment of targets to be analysed is unit, that is function or class. Today's software development is to deal with huge change of software product and huge class including heavy quantity of LOC(Lines Of Code). However, analysis of unit is not precise approach process for reliable reengineering consequence. In this paper, we propose very precise hot spot analysis approach using Aspect-Oriented Programming languages, such as AspectJ. Typically the consistency between UML and source is needed code to redefine the modified library or framework boundaries. But reengineering approach using AOP doesn't need to analyze UML and source code. This approach makes dynamic event log data that contains detailed program interaction information. This dynamic event log data makes it possible to analyze hot spot.

Software(S/W) reengineering is one of the effective technologies to produce a business worth and en and the S/W ROI continuously. In spite of, S/W reengineering has been recognized a cost-consumptive works with inefficient productivity. In fact we have used to transform to confusion system with destructive system architecture by extending and updating legacy system in a temporary expedients. Moreover it is impossible to provide the time-market products for coping with rapid changeable system environment and meeting to complicated customer's requirements. Therefore, we need a systematic reengineering methodology to fulfill the changeable environment, as appearance of new IT techniques, various alteration of business information model, and increment of business logic. Legacy systems can be utilized as the core property in business organization through reengineering methodology. In this paper, we target to establish the reengineering process, proposed MaRMI-RE consisting of initial Planning phase, reverse engineering and component transformation phase. To describe the MaRMI-RE, we presented the concrete tasks and techniques and artifacts per individual phase in process, and the case study is showed briefly.

Hospital managements are faced with severe competition and need more complicated information systems for its efficiency than before. Hospital managers have to deal with these environments and provide patients with better services than ever to survive. This thesis analyzes and redesigns the hospital administration processes in terms of patient-oriented view. For that purpose we define the processes of the hospital administration using process design tool like ARIS-Toolset. We also introduce basic concepts of Hospital Information Systems(HIS). We finally reviewed the result of reengineering of hospital management process with AHP methodology.
