Information technology's potential for changing processes is widely acknowledged and various information technologies exist as a tool making business reengineering possible. Groupware is one of information technology that typically work in concert to bring out change in processes. This paper attempts to explain the importance of groupware as a critical information technology for business reengineering by developing a methodology of applying groupware to business reengineering. In order to understand the applicability of groupware to business reengineering, this paper has the following objectives. 1) Examines how the capability of groupware can play as a chang lever or enabler of process innovation explicitly. 2) Propose a integrated business reengineering methodology that incorporates process, process environment and information technologies specifically. A case study was used to provide the insight how groupware can play as a enabler of process innovation. The case was analyzed according to the reengineering methodology we proposed.

Reengineering, also known as a business process redesign, involves a fundamental rethinking, and often a radical redesign, of an entire business process or a set of process to achieve dramatic improvements. The central paradox of reengineering is that its own advantages constitute the greatest threat to its success. For reengineering to be the right choice, the organization must have real capacities to embrace changes across the board. The key is to begin with, and to preserve, a vision of the new order, which drives this structured approach, and is in turn calibrated by that approach. However, in most cases of these calibrations, the empirical evidences on the effect of determinants in the reengineering are required. Seemingly, the research results in this area are scarcely verified. This article tried to search the effect of four dimensions of the reengineering toward the performance of reengineering. The results showed that the factors of the organization behavior and of the methodology/operation had more affected on the performance.

The purpose of this study is to identify the factors hindering hospital reengineering project in one university hospital. The data was collected by the self-administered Questionnaire to 288 members of the hospital in Pusan on April 5-18, 1996. This study took some statistical methodologies, such as descriptive analysis, factor analysis and logit model analysis. The results were as follows; First, in the descriptive analysis for whether the hospital reengineering named RUSH94 was a success or not, the subjects judged that it was not successful and regarded their fable mutual communication as the main factor. Second, in the reason of failure at the reengineering project, the group who thought that the failure factor was the lack of mutual consensus checked the scores of the first factor produced from the factor analysis.

The automatic train control (ATC) system development project for the Automated Guideway Transit (AGT) system has high technical risk because the system is unmanned train control system using wireless technology which was unprecedented in train control industry of Korea. To overcome the technical risk during concept design phase of the ATC system development project, the integrated product team(IPT) carried out a reverse and reengineering process using a systems engineering design model. The generic systems engineering process is incorporated in the both reverse and reengineering process. As a result of the systems engineering effort, the IPT has built top layer systems engineering design model of the ATC subsystem. The purpose of this paper is to deliver the reverse and reengineering process which was used to develop the systems engineering design model of ATC system using a computer aided systems engineering tool. This study also shows that the model based reverse and reengineering process can reduce the technical risk by identifying the differences of requirement, functional and physical architecture between a reference system and a target system.

Today, many organizations are reengineering themselves to develop new ways to thrive in a foreign and unforgiving business environment. However, it is reported that many companies involved in the project of business process reengineering are dissatisfied with their results. Therefore, we developed an exploratory framework based on three constructs such as critical success factors, organizational maturity level, and performance and applied these to help analyze current practice in business process reengineering. To proceed with our research, this paper was organized around two research questions in business process reengineering. We addressed: (1) To what extent does certain critical success factors correlate with performance? and (2) How does the relationships between critical success factors and performance differ by organizational maturity level? From the research results, we could find relationships between critical success factors(i.e., project management, change management, objective management) and performance, and could verify differences in performance of organizations grouped by organizational maturity level.

This study is a discussion of business process reengineering for the next generation information system. To be concrete, we analyze and reengineer the current business process in administration of academic, general and research. This reengineering is conformed by 5 steps, as analyzing environmental status that figures out factors of inside or outside (environmental analyzing), analyzing current condition that diagnoses AS-IS process (current situation analysis), establishing information-oriented vision with strategic accomplishing goals accordingly (visioning), deducing detailed improving tasks (defining tasks), and engineering TO-BE process comprehending improving matters (engineering model). This paper shows BPR model for next generation information system.

The focus of Business Process Re-engineering (BPR) has been extended to inter-business process that cuts across independent companies. Combined with Supply Chain Management (SCM), inter-business process reengineering (IBPR) focuses on synchronization of business activities among trading partners to achieve performance improvements in inventory management and cycle time. This paper reviews the business process reengineering movement from the historical perspective and presents a case of inter-business process reengineering using the latest internet-based Business-to- Business (B2B) technology based on Collaborative Planning, Forecasting, and Replenishment (CPFR). The case demonstrates how CPFR technology reengineers the distribution process between Heineken USA and its distributors. As world's first implementor of web-based collaborative planning system, Heineken USA reduces cycle time from determining the customer need to delivery of the need by 50% and increases sales revenue by 10％. B2B commerce on the internet is predicted to grow from $90 billion in 1999 to $2.0 trillion in 2003. This paper provides the management with the bench-marking case on inter-business process reengineering using B2B e-commerce technology.

현실 세계의 복잡한 비즈니스 로직들이 프로그램 내부에 투영되면서 시스템의 복잡도는 갈수록 높아지고 있다. 이러한 높은 복잡도를 가지는 프로그램도 그 생명주기 동안 재공학을 거쳐야 하는 것은 필연적일 것이다. 다양한 목적으로 가해지는 재공학 작업에서 그 작업의 대상이 되는 핫 스팟 예측은 매우 중요하다. 일반적으로 레거시 시스템의 재공학 작업은 UML과 코드 분석을 기반으로 예측한다. 또한 그 예측 단위는 클래스 혹은 유닛(함수) 단위가 된다. 그러나 함수 내부의 코드의 량이 갈수록 커져가고 있고 더 미세한 핫 스팟을 찾기 위하여 클래스 단위의 탐색보다 더 미세한 부분의 탐색이 필요하다. 본 논문에서는 AOP를 이용한 문장 단위의 핫 스팟 검출 기법을 제안한다. 기존의 기법에서 요구하던 핫 스팟 검출을 위한 UML과 코드 분석, 또한 이 둘 사이의 일치성과 관계없이 동적으로 AOP를 이용하여 레거시 시스템의 실행 정보를 기록하는 동적 이벤트 로그 데이터를 생성한다. 이를 바탕으로 핫 스팟을 예측하고 슬라이싱하는 방법을 제안하였다.

소프트웨어(S/W) 재공학은 S/W의 생명주기의 연장을 통한 지속적인 비즈니스 가치 창출 및 궁극적인 S/W ROI(Return on Investment) 확대에 가장 효과적인 기술 중 하나이다. 그럼에도 불구하고 S/W 재공학은 비용 소모적이며, 그 효과 역시 미흡한 어려운 작업으로 인식되어 왔다. 사실, 빈번히 발생하는 유지보수 요구에 대해 레거시 시스템들을 일치성 없이 그때그때 확장, 수정함으로써, 기존 시스템 본연의 의도를 상실 시켜 S/W시스템 아키텍쳐가 존재하지 않는 난잡한 시스템으로 전환시키는 경우가 종종 발생하고 있다. 더욱이 급격히 변하는 시스템 환경과 복잡 다양해지는 고객의 요구를 충족시킬 수 있는 새로운 S/W 시스템들을 매번 적시에(Time-to-Market) 제공하기는 거의 불가능하다. 따라서, 새로운 IT 기술의 출현과 비즈니스 정보 모델의 다양한 변경, 시스템 처리 로직의 급격한 복잡성 증가 등의 변화에 적절히 대처하기 위해서는 조직의 주요 자산으로서 레거시 시스템의 활용을 극대화할 수 있는 체계적인 재공학이 요구된다. 그러므로 본 논문에서는 레거시 시스템들의 가치를 극대화할 수 있는 체계적인 재공학 방법론 제공을 목적으로, 재공학의 초기 계획 단계에서부터 역공학 과정과 컴포넌트 변환 단계를 포함하는 재공학 프로세스와 그에 따른 구체적인 작업과 기법 및 산출물들을 명시한 레거시 시스템의 컴포넌트화 프로세스인 마르미-RE를 제안하고 간단한 사례적용 과정을 제시한다.
