Recently, enterprise systems require the necessity of integration for data sharing and cooperation. As a methodology for integration, Service-Oriented Architecture for service integration and Master Data for integration of data, which is used for service, were appeared. This paper suggests a method that operates BP(Business Process) efficiently. We make XMDR(eXtended Meta Data Registry) as knowledge-repository to support the BP and construct data hubs to operate it. XMDR manages MDM(Master Data Management) to integrate the data, resolves heterogeneity between the data and provides relationship to the business efficiently. This is composed of MDR(Meta Data Registry), ontology and BR(Business Relations). MDR describes relationship between meta data to solve structured heterogeneity. Ontology describes semantic heterogeneity and relationship between data. BR describes relationship between tasks. XMDR data hub supports the management of master data and interaction of different process effectively.

As more than 80 percent of tasks within corporations are performed through information systems, they have become large in scale and complicated, which make the range of the system users diverse and specialized. and as recent corporate strategies focus on the real-time environment in businesses, the organizational structure within companies tend to show frequent changes. In order to ensure the business continuity in this environment, the most important aspect is to prevent incompleteness of business by narrowing the gap of understanding of business process between the system users and the maintenance managers. In order to address this problem, this study suggests a modeling method that utilizes business scenarios reflecting actual business rules and procedures which ultimately transforms the optimized and standardized form of business scenarios into the actual software maintenance activities. This modeling method improves reusability and usability through the repeated feedback mechanism for modified software by leading to gradual fine-grained process. The feasibility of this is to be proven by applying the modeling method to the real business environment.

With the drastic changes toward open innovation, there have been many studies focusing on analyzing the characteristics of open innovation and fostering the open innovation. The most prominent research in open innovation literature is related to the partner selection. In partner selection process, what is important is to identify the expected performance when conducting open innovation with this partner. Therefore, this study suggests an integrative framework of BSC-AHP to support the effective partner selection. The aim of this study is to select the most desirable partner which maximize the performance of the firm after conducing open innovation. This paper employs BSC framework to prepare and characterize relevant decision criteria for the partner selection, and employs AHP to evaluate the partner alternatives under the prepared decision criteria.

Balanced Scorecard(BSC) is one of the ways to estimate the achievement results of enterprises which, beyond the simple financial index traditionally used for enterprise achievement result management system, aims to estimate and manage the key perspectives for the future and goal achievement of enterprises as financial perspectives, customer perspectives, internal business perspectives, learning and growth perspectives with a fully consistent and balanced measure, and moreover manage their relationships regarding cause and effect on its basis. Introduction of BSC can be a profound implication for management strategies not only in that its introduction itself has numerous direct effects but also in the way of understanding whether or not its sequential relations exist. Thus this study focused on if the introduction of BSC is effectual, and if there exist any time-lag sequential relations between the effects. The results of the this study indicate that the introduction of BSC has positive effects on the internal business perspectives, learning and growth perspectives, financial perspectives, with the last aspect lasting longer. After dividing perspectives of BSC into leading indicator and lagging indicator, the analysis on if there was some relationships between two indicators was done. As a result, the introduction makes internal process improve first, which has positive effects on financial performance next.

Services are reusable units in business level. Ubiquitous computing provides computing services anytime and anywhere. The combination of both is becoming an important paradigm of computing environment. Fundamentals of services require flexibility and interoperability, and key elements of ubiquitous modeling require interoperability and context-awareness. There are two kinds of methods to identify services. The top-down approach is based on business process, and the bottom-up approach is based on components. The first approach depends on experts' intuitions, while the second approach suffers the incapability of expressing non-functional expression through components. Although a feature-based approach is capable of expressing non-functional expression and identifying services in ubiquitous environment, the research on this issue is not adequately addressed by far. To promote this research, this paper proposes a feature-based method to identify services in ubiquitous computing. The method extracts initial-candidate-services from a feature model. Then, the ultimate services are identified through optimizing and analyzing the candidate-services. The proposed method is expected to enhance the service reusability by effectively analyzing ubiquitous domain based on feature, and varying reusable service units.

The trend of business work that is related to supply chain changed into e-business using the electronic document However, the small and medium enterprise organizations still use huge volume of paper document, especially in private sector. Recently, the need for eco-friendly and low cost logistics becomes increasing. For this, it has expanded to exchange or to use e-document rather than the paper or manual processing in supply chain business. Therefore, this paper proposed the electronic access system for supply chain by business process modeling. If it is using the proposed system, it can be saving the exchanged or the scanned document to system, and user can utilize that document on just accessing system whenever they need the document. We believe it might reduce the burden of each organization because they don't need to save large volume data to their system or place. Furthermore, the benefits will effect across the national as well as global.

XBRL is an XML-based language, actively used for diverse business reporting applications including financial reporting. It can be flexibly applied to each application by defining concepts and their relationships existing within the application. In these business reporting processes, it is very important for senders and receivers to validate the consistency and completeness of reporting contents in the syntatic and semantic levels. The basic method is to directly represent and validate the semantic constraints using application program codes. However, the method makes it difficult to represent, change, share semantic constraints. While XML constraint languages for XML documents such as XSLT and Schemantron support explicit representation and sharing of semantic constraints, they are limited in the efficiency and effectiveness of representing XBRL semantic constraints. This paper reviews XBRL formula, actively being discussed recently for standardization, and discusses the representation capability and limitations through a case analysis, which applies XBRL formula to business documents in the area of financial reporting.

IT 거버넌스(Governance)는 IT 관련 의사결정에 있어서 기업 내부 주체들의 권한과 책임, 의사결정 조직체계와 프로세스, 의사소통 방법, 의사결정 실현 체계, 조정과 통제, 그리고 의사결정에 대한 사후 평가 등을 통틀어 일컫는 말이다. IT가 기업 경영의 필수 인프라로 인식되고, 기업의 경쟁력 제고의 핵심 역량으로 자리잡으면서 IT 거버넌스의 중요성은 점차커지고 있다. 본 연구에서는 국내 주요 대기업들의 IT 거버넌스를 분석하였다. 4개의 국내 대기업들에 대한 심층 인터뷰를 바탕으로, 이들 기업들이 어떤 조직 체계와 과정, 의사소통 체계, 그리고 성과 측정 방법 등을 가지고 IT 관련 의사결정을 하는지를 살펴보았다. 국내 대기업들은 IT 서비스를 전문적으로 제공하는 IT 서비스 계열사를 이용하여 IT 기능을 아웃소싱하고 있었으며, IT 관련 최종 의사결정은 IT 전문 조직이 아닌 비즈니스를 담당하고 있는 경영자들이 하는 것으로 나타났다. 국내 대기업들의 IT 서비스에 대한 계약과 성과 측정은 서비스 수준 협약을 통해 이루어지고 있었으며, 국제적으로 인정되고 있는 프로젝트 관리 방법론과 균형성과 기록표 등도 널리 사용하고 있었다. 이러한 연구는 국내 대기업 내의 IT 서비스 전문 기업들의 미래 역할 정립과 정부 기관이나 공기업들의 IT 거버넌스 체계 확립에 있어서 벤치마킹 근거로 활용될 수 있다. 또한 국내 대기업들의 IT 거버넌스 체계의 효율성 등을 측정하기 위한 기초 자료로 이용될 수 있다.
