ABSTRACT

Knowledge Management Strategy can be classified by codification strategy and personalization strategy (Hansen et. al., 1999), and how to manage the two strategies were always studied. Also, current studies regarding the knowledge management strategy were targeted mostly for major companies, resulting in lack of studies in how it can be applied on SMEs. This research, with the knowledge management strategy suited for SMEs, sets an Enterprise Microblog (EMB), and with the EMB applied on SMEs’ Knowledge Management Strategy, it is reviewed on the perspective of SMEs’ Codification and Personalization Strategies. Through the advanced research regarding Knowledge Management Strategy and EMB, the hypothesis is set that “Depending on the development of the company, the main application of EMB alters from Codification Strategy to Personalization Strategy.” To check the hypothesis, SME that have used the EMB called ‘Yammer’ was analyzed from the data of their foundation until today. The case study has implemented longitudinal analysis which divides the period when the EMBs were used into three stages and analyzes the contents. As the result of the study, this suggests a substantial implication regarding the application of Knowledge Management Strategy and its Knowledge Management System that is suitable for SME.

ABSTRACT

지식경영전략은 코드화(Codification) 전략과 대인화(Personalization) 전략으로 대별할 수 있으며(Hansen et al., 1999), 성공적인 지식경영의 도입과 활용을 위한 두 전략의 운영 방안에 대한 연구가 계속되어 왔다. 그리고 지식경영 시스템에 대한 기존 연구는 주로 대기업의 일부 조직에서 활용한 사례를 대상으로 하고 있어, 중소 규모의 기업 전체를 대상으로 하는 연구는 미비한 실정이다. 본 논문은 중소 규모의 기업에 적합한 지식경영 시스템으로 기업용 마이크로블로그를 특정하고, 기업용 마이크로블로그를 활용한 중소기업의 지식경영전략을 코드화 전략과 대인화 전략의 관점에서 검토한다. 지식경영전략과 기업용 마이크로블로그에 대한 선행연구를 통하여 “기업의 성장에 따라 기업용 마이크로블로그의 활용은 코드화 전략에서 대인화 전략 중심으로 변화한다”는 가설을 설정하였다. 이 가설을 확인하기 위하여 창업 초기부터 현재까지 ‘야머’(Yammer)라는 기업용 마이크로블로그를 사용하고 있는 소규모 기업을 대상으로 사례연구를 진행하였다. 사례 연구는 기업용 마이크로블로그의 사용 기간을 창업 ‘초기’, 현재의 조직 형태를 갖추게 된 ‘중기’, 그리고 연구가 진행된 ‘현재’ 등 세 시점으로 나누고 콘텐츠를 분석하는 종단 분석을 실시하였다. 그리고 각 시점별 야머에 등록된 콘텐츠의 커뮤니케이션 유형을 분석하여 사례기업의 기업용 마이크로블로그 사용행태를 분석하고, 지식경영전략의 변화를 확인하는 방법을 사용하였다. 연구의 결과로 소규모 기업에서 지식경영전략의 운영과 그에 적합한 지식경영 시스템의 활용에 대한 실질적인 시사점을 제시하고자 한다.

ABSTRACT
Product Service System(PSS), which is an integrated combination of product and service, provides new value to customer and makes companies sustainable as well. The objective of this paper draws Critical Successful Factors(CSF) of PSS through multiple case study. First, we review various concepts and types in PSS and Platform business literature currently available on this topic. Second, after investigating various cases with the characteristics of PSS and platform business, we select four cases of ‘iPod of Apple’, ‘Kindle of Amazon’, ‘Zune of Microsoft’, and ‘e-book reader of Sony’. Then, the four cases are categorized as successful and failed cases according to criteria of case selection and PSS classification. We consider two methodologies for the case selection, i.e., ‘Strategies for the Selection of Samples and Cases’ proposed by Bent(2006) and the seven case selection procedures proposed by Jason and John(2008). For case selection, ‘Stratified sample and Paradigmatic cases’ is adopted as one of several options for sampling. Then, we use the seven case selection procedures such as ‘typical’, ‘diverse’, ‘extreme’, ‘deviant’, ‘influential’, ‘most-similar’, and ‘mostdifferent’ and among them only three procedures of ‘diverse’, ‘most?similar’, and ‘most-different’ are applied for the case selection. For PSS classification, the eight PSS types, suggested by Tukker(2004), of ‘product related’, ‘advice and consulancy’, ‘product lease’, ‘product renting/sharing’, ‘product pooling’, ‘activity management’, ‘pay per service unit’, ‘functional result’ are utilized. We categorize the four selected cases as a product oriented group because the cases not only sell a product, but also offer service needed during the use phase of the product. Then, we analyze the four cases by using cross-case pattern that Eisenhardt(1991) suggested. Eisenhardt(1991) argued that three processes are required for avoiding reaching premature or even false conclusion. The fist step includes selecting categories of dimensions and finding within-group similarities coupled with intergroup difference. In the second process, pairs of cases are selected and listed. The second step forces researchers to find the subtle similarities and differences between cases. The third process is to divide the data by data source. The result of cross-case pattern indicates that the similarities of iPod and Kindle as successful cases are convenient user interface, successful plarform strategy, and rich contents. The differences between the successful cases are that, wheares iPod has been recognized as the culture code, Kindle has implemented a low price as its main strategy. Meanwhile, the similarities of Zune and PRS series as failed cases are lack of sufficient applications and contents. The differences between the failed cases are that, wheares Zune adopted an undifferentiated strategy, PRS series conducted high-price strategy. From the analysis of the cases, we generate three hypotheses. The first hypothesis assumes that a successful PSS system requires convenient user interface. The second hypothesis assumes that a successful PSS system requires a reciprocal(win/win) business model. The third hypothesis assumes that a successful PSS system requires sufficient quantities of applications and contents. To verify the hypotheses, we uses the cross-matching (or pattern matching) methodology. The methodology matches three key words (user interface, reciprocal business model, contents) of the hypotheses to the previous papers related to PSS, digital contents, and Information System (IS). Finally, this paper suggests the three implications from analyzed results. A successful PSS system needs to provide differentiated value for customers such as convenient user interface, e.g., the simple design of iTunes (iPod) and the provision of connection to Kindle Store without any charge. A successful PSS system also requires a mutually benefitable business model as Apple and Amazon implement .

Bankruptcy Prediction Modeling Using Multiple Neural Network Models

Abstract

The primary goal of this paper is to get over the limitations of single neural network models through model integration so as to increase the accuracy of bankruptcy prediction. We take the closeness of the output value to either 0 or 1 as the models confidence in its prediction as to whether or not a company is going to bankrupt. In case where multiple models yield conflicting prediction results, our integrated model takes the output value of the highest confidence as the final output. The output of the confidence-based integration approach significantly increases the prediction performance. The results of composite prediction suggest that the proposed approach will offer improved performance in business classification problems by integrating case-specific knowledge with the confidence information and general knowledge with the multi-layer perceptrons generalization capability.

Abstract  

Artificial neural network (ANN) modeling has become the dominant modeling paradigm for bankruptcy prediction. To further improve the neural networks prediction capability, the integration of the ANN models and the hybridization of ANN with relevant paradigms such as evolutionary computing has been demanded. This paper first attempted to apply neurogenetic approach to bankruptcy prediction problem for finding optimal weights and confirmed that the approach can be a good methodology though it currently could not outperform the backpropagation learning algorithm. The result of this paper shows a possibility of neurogenetic approach to bankruptcy prediction problem since the simple neurogenetic approach produced a meaningful performance.

Support Vector Machines Approach to Pattern Detection in Bankruptcy Prediction and its Contingency

Abstract

This study investigates the effectiveness of support vector machines (SVM) approach in detecting the underlying data pattern for the corporate failure prediction tasks. Back-propagation neural network (BPN) has some limitations in that it needs a modeling art to find an appropriate structure and optimal solution and also large training set enough to search the weights of the network. SVM extracts the optimal solution with the small training set by capturing geometric characteristics of feature space without deriving weights of networks from the training data. In this study, we show the advantage of SVM approach over BPN to the problem of corporate bankruptcy prediction. SVM shows the highest level of accuracies and better generalization performance than BPN especially when the training set size is smaller.

Lee, K., Jeon, B., “Analysis of Best Practice Policy and Benchmarking Behavior for Government Knowledge Management,” Lecture Notes in Computer Science, pp. Vol. 3035, 70 – 79, May, 2004. – SCIE, ISSN:0302-9743. pdf

Abstract

Korean government has several best practice competition and diffusion programs for the purpose of public administration reform and the improvement of government service. From the perspective of knowledge management, this paper evaluates the best practice policy and analyzes the main factors influencing the recognition, adoption and utilization of best practices through the email-based survey and interview with local government officers. The result shows that 1) The government officers’ recognition of best practice programs and the best practices themselves is not high, 2) The adoption and utilization of a best practice is affected by its value and officer’s information needs, 3) Raising the recognition of Best practice policy affects the recognition and adoption of a best practice, and 4) The recognition and utilization of a best practice is affected by the work experience. The result gives important implications for designing and implementing government knowledge management systems and strategies.
