User Involvement in Information System Development : An applicator of the Vroom-Yetton Model
강신철 牧園大學 産業經營硏究所 1990 産經硏究 Vol.6 No.-
User involvement in information system development is widely accepted as a necessary conditon for the success of computer-based inforamtion systems. However, it is not yet clear what activities and to what degree users should be involved in an information system development life cycle (SDLC). This paper reports on the successful use of the Vroom-Yetton model in determining the types of system development activites and the degree to which users are encouraged to participate in such activities. Semistructured on-site interviews were conducted at 17 companies located in miwestern cities. The results shed light on the applicability of the Vroom-Yetton model in information system development. The Vroom-Yetton model is a contemporary theory of leadership. It attempts to prescribe a leadership style appropriate to a given situation (Vroom and Yetton, 1973). The merit of applying the Vroom-Yetton model to information system development lies in the fact that the model to information system development lies in the fact that the model to imformation system development lies in the fact that the model concerns itself only with the relationship between leader behavior and subordinate participation in decision making. A leader in a system development project, whether a system manager or a head of steering committee, should decide which activities and to what degree users are encourged to participate. Since user involvement requires a great deal of commitment form both users and managers in terms of time and efforts, it must be cost-effective. The model takes the form of a decision tree. The attributes of a system development activity are arranged along the top of the decision tree and are expressed as yes-no questions (see Figure 1). To use the model, the decision-maker starts at the left-hand side of the diagram and asks the question corresponding to attribute A. For instance, the system manager first decides whether the system development activity involves a quality requirement, The answer determines the path to the second mode on the decision tree, where the question pertaining to that attribute is asked. This process continues until a erminal node is reached. The system manager in this way can identify an appropriate level of user involvement in each system development activeity.

본 연구는 정보화시대에 군이 변화하는 환경에 적응할 수 있도록 (1) 군사혁신의 구성요소와 정보기술이 국방영역에 미치는 영향을 분석하고, (2) 혁신 대상이 되는 전환과제를 도출하며, (3) 선진국의 군사혁신 사례 및 우리 군의 현 실태를 비교 분석하여 정보화환경과 부적합한 요소를 분석하고, (4) 도출된 혁신과제를 수행하기 위한 방안을 제시하는데 목적이 있다. 군사혁신의 구성요소를 현재 군사분야의 임무별/사업별 핵심영역이라고 할 수 있는 국방전략, 조직구조 및 환경, 교육훈련, 군사기술, 군수 및 병참 등 5개 과제에 한정하고, 이 5개 분야가 변화된 정보화 환경에 어떻게 영향을 받고 있으며, 부적합요소가 무엇이며, 어떻게 개선할 것인가 하는 혁신방안을 제시하였다. 군사혁신의 구성요소와 정보기술이 국방영역에 미치는 영향을 분석하기 위해 미군의 군사혁신 사례 및 경향을 분석하여 시사점을 도출하고, 그 기준에 의거 우리 국방의 현 실태를 진단한 뒤 추진방안을 제시하였다. To preserve competitiveness in rapidly changing world military market and to adapt themselves to newly-developed warfare, many developed counties have been readjusting their military organizations and technical procedures. In a private sector, business reengineering and other innovative efforts were made to respond to this change, using structural approaches. In the military sector, the United States is the one leading this move. She has been trying to reorganize her military structure to hold her hegemony in world politics for the coming 21st century. The purpose of this paper, is, (1) to analyze the information technology on the military revolution, (2) to deduce what to be changed, and (3) to infer how to change. The comparison between Korea and U.S. in terms of the real military situation was made to analyze these three research questions. The study was based on the structural contingency theory, one of the environmental analysis models, being introduced to explore the Revolution in Military Affairs(RMA) case in United States and Korea. The conclusion may be summarized as follows; First, information-based society which is characterized by the development of information technology and environmental, complexity and weakness in security affairs will affect the military factors such as the issue of holding information superiority, changing warfare in proportion to the military-scientific development and weakness in military security. This trend will be more deep-rooted and multiple in its influence on the military affairs.

Objectives The purpose of this study is to investigate the mediating effect of group counseling working alliance on the relationship between training group member's group leader self-efficacy and session evaluation of group counseling, as well as examine whether this path is moderated by group member-perceived group leader characteristics. Methods For this purpose, an on-line survey was conducted on the experiences of participating training group as a group member for counselors working across the country. Data from 285 participants were collected and analyzed by using SPSS 25.0 and Process Macro Program. First, the causal steps approach and bootstrapping were used to verify the mediating effect. Second, a hierarchical regression analysis and verification of conditional indirect effect were performed to verify moderating effect. Third, bootstrapping and Jonson-Neyman technique were applied to verify moderated mediating effect. Results The major results are as follows: First, a group counseling working alliance was found to partially mediate the relationship between group members' group leader self-efficacy and group counseling session evaluation. Second, the group leaders’ characteristics perceived by group members were found to moderate the relationship between group members' group leader self-efficacy and group counseling working alliance. Third, the moderated mediating effect was confirmed that group counseling working alliance mediated the path of group members’ group leader self-efficacy to group counseling session evaluation, and the group member-perceived group counselor characteristics moderated the relationship between group members’ group leader self-efficacy and working alliance of group counseling. Conclusions These results showed that the group member-perceived group leaders’ characteristics and the group counseling working alliance were significant in the process that the training group members’ group leader self-efficacy affected the group counseling session evaluation. Based on the study results, study Implications and limitations were discussed. 목적 본 연구의 목적은 집단상담 훈련집단 집단원의 집단상담자 자기효능감과 집단상담 회기평가의 관계를 집단상담 작업동맹이매개하며, 이 경로를 집단원이 지각한 집단상담자 특성이 조절하는지를 조사하는 것이다. 방법 이를 위해 전국의 상담자들을 대상으로 집단상담에 집단원으로 참여했던 경험에 관한 온라인 설문조사를 실시하였다. 수집한285명의 데이터를 SPSS 25.0과 Process Macro 4.0 프로그램을 사용하여 분석하였다. 첫째, 인과적 단계접근법과 부트스트래핑을 통해 매개효과를 검증하였다. 둘째, 위계적 회귀분석과 조건부 조절효과 검증을 통해 조절효과를 검증하였다. 셋째, 부트스트래핑과 Johnson-Neyman 검증을 통해 조절된 매개효과를 확인하였다. 결과 본 연구의 주요 결과는 다음과 같다. 첫째, 집단상담 작업동맹은 집단원의 집단상담자 자기효능감과 집단상담 회기평가 간의관계를 부분매개하는 것으로 나타났다. 둘째, 집단원에 의해 지각된 집단상담자 특성은 집단원의 집단상담자 자기효능감과 집단상담 작업동맹의 관계를 조절하는 것으로 나타났다. 셋째, 지각된 집단상담자 특성에 의해 조절된 집단상담 작업동맹이 집단원의 집단상담자 자기효능감과 집단상담 회기평가 간의 관계를 매개하는 조절된 매개효과가 검증되었다. 결론 집단상담 훈련집단 집단원의 집단상담자 자기효능감이 집단상담 회기평가에 영향을 미치는 과정에서 집단원이 지각한 집단상담자 특성과 집단상담 작업동맹의 중요성을 확인하였다. 연구 결과를 바탕으로 본 연구의 시사점과 제한점을 논의하였다.
