Research to date for decision-making on outsourcing has almost exclusively focussed on strategic and operational levels. Consequently, we know relatively little about decision-making on outsourcing during design and engineering, i.e. the tactical level; that also means that the characteristics of design and engineering – incomplete and inaccurate information and progressive availability of data – are not incorporated in existing frameworks and methods at that level. To fill this gap, a first-of-its-kind framework, based on an extensive appraisal of the literature, is validated; to that purpose, a Delphi survey was undertaken gauging the opinions of two homogeneous groups of academic and industry experts. The analysis of the survey affirms the assumptions made about the role of the progressive availability of data during decision-making on outsourcing. The results from this study should not only inform further research into decision-making during design and engineering but potentially the framework might also have validity for purchasing at the tactical level and strategic decision-making on outsourcing.  相似文献

Information matrices are often the output produced by a decision support system. These matrices are a common method for expressing a decision situation under different decision-making scenarios. The decisions involved in designing a decision support system to generate the information matrix are important and involve several cost and benefit components. A designer needs guidance in making effective design decisions in this context. Such guidance can be provided by considering the relationships among specific design decisions, costs, and benefits. The general objective of this study is to provide a comprehensive framework for this purpose. This study is the first to develop and present a comprehensive cost-benefit framework for evaluating design decisions for a variety of scenarios. The specific objective of this research is to provide guidance regarding the number of available information dimensions to incorporate in a computer-based decision aid. Simulation experiments are conducted with a completely specified model based on the cost-benefit framework (including needed assumptions) to evaluate how many information dimensions to include for a specific information matrix size to achieve a balance between information use costs and decision quality. Based upon extensive simulation analyses for a hypothetical decision maker, the practical guideline found for designers is to include only the top half of the relevant information dimensions in any specific decision support system. Over a large number of repeating choice decisions, the savings in cognitive effort and information gathering costs clearly offset relatively minor losses in decision quality.  相似文献

The emergence of the Internet may have fundamentally altered the mechanisms underlying information exchanges between sellers and end consumers. However, little attention has been given to the impact these mechanisms have on the efficiency of supply chain operations. This paper begins to address this deficiency in the literature by evaluating supply chain transaction efficiency effects from Internet purchases by consumers. It develops and empirically tests a theoretical framework examining the role Internet purchases have in establishing transaction‐efficiency levels in product exchanges involving sellers, placed at different supply chain echelons, and consumers. The theoretical framework integrates the transaction‐cost and internet economics, inter‐organizational information systems, and supply chain management literatures. Empirical testing, via structural equation modeling, is based on archival data in the Internet music CD market. The results show that Internet‐mediated purchases by consumers allow for greater transaction efficiencies when inventory ownership is postponed farther upstream in the supply chain and supply chain echelons are disintermediated. The results also indicate that channel structure configuration, defined by the supply chains' Internet retailing echelon, moderates these transaction efficiency effects.  相似文献

The value that is placed on information by managers, who are the users of information systems, is an important construct in all aspects of systems design, development and evaluation. This study uses a multidimensional attribute approach to assess the value of information and reports on tests of hypotheses related to differences that have been assumed to exist among managers in various functional areas and at various hierarchical levels in a business firm. The results generally fail to confirm the existence of such differences.  相似文献

Applications of DDP are examined via two case studies to determine how the technology was used by management to aid decision-making; the level of management involvement in the MIS (Management Information Systems) design process and the nature of the relationship between managers and data processing departments were also considered. The study showed that because the technology was largely under end user control, better tailored information systems resulted and system output was more directly used by middle and top managers. This only occurred, however, if certain moderators, such as computing and modelling skills, were present in functional departments. DDP also offers opportunities for better relationships with data processing departments but the consequences include the need for better management training and functional support groups for systems implementation. A conceptual model is presented as a theoretical framework to guide organisations when using DDP.  相似文献

Recent publications suggest that existing management accounting and control systems prevent business unit managers realising their desired competitive advantage. Although the concept of competitive advantage has already been thoroughly discussed in strategy literature, it has not yet been integrated in the management accounting and management control frameworks. Only a limited number of researchers have concentrated on contingency research in this area. Contingency theory simply states that organization structure, process and management control systems are contingent upon various internal and external factors, such as industry, technology, size, culture and strategy (Anthony and Young, 1988; Anthony et al., 1992). This article is an attempt to identify and investigate the management control – strategy relationship. We report the results of our exploratory field research in 18 companies (32 business units). Based on our results, we formulate some hypotheses on the observed characteristics of the management control process in case of low-cost strategy, differentiation strategy in a standard product environment and differentiation strategy for customized products (make to order, engineer to order).  相似文献

Intrusion detection systems help network administrators prepare for and deal with network security attacks. These systems collect information from a variety of systems and network sources, and analyze them for signs of intrusion and misuse. A variety of techniques have been employed for analysis ranging from traditional statistical methods to new data mining approaches. In this study the performance of three data mining methods in detecting network intrusion is examined. An experimental design (3times2x2) is created to evaluate the impact of three data mining methods, two data representation formats, and two data proportion schemes on the classification accuracy of intrusion detection systems. The results indicate that data mining methods and data proportion have a significant impact on classification accuracy. Within data mining methods, rough sets provide better accuracy, followed by neural networks and inductive learning. Balanced data proportion performs better than unbalanced data proportion. There are no major differences in performance between binary and integer data representation.  相似文献

The conventional approach to computerization in a large hospital is to establish an internal data processing (DP) department and DP professionals then begin to develop computer-based information systems (CBIS). For medium-sized hospitals, however, this approach is doubtful. The limitation of financial resources and the lack of skilled systems professionals force the medium-sized hospital to consider different approaches. In this paper, we present a conceptual framework for the computerization of a medium-sized hospital based upon the viewpoint of top management. Based on the conceptual framework presented, a PC-based application software package has been developed, tested, and implemented at Cheng-Ching Hospital in Taiwan. Our study shows that a medium-sized hospital can initiate and conduct computerization in very short time with low cost and without an internal DP department.  相似文献

Decision support system (DSS) researchers and designers continue to look for unstructured organizational tasks where there is a critical need for intelligent computer-based support. One such decision task is information requirements determination. Requirements determination is recognized as the most crucial phase of the systems development life cycle. Unfortunately, most methodologies and CASE tools focus only on how to specify the requirements once they are determined. There is very little computer support for the process of determining requirements. This paper discusses the conceptual design and development of a knowledge-based DSS to support information analysts in the critical decision task of determining requirements for the design of effective information systems. The expert modeling support system has the expertise to assist the analyst in studying the organization as a whole and in modeling the system under study in the context of the overall organization's goals and needs. The focus of the paper is on the problems associated with building the knowledge base component of the intelligent decision support system. A prototype implementation of the system is described.  相似文献

Informatics is an indispensable discipline for leaders and managers--of patients, facilities, and organizations--because the most important assets of those organizations are their information processing technologies, and the key skills are those that help them to manage information. Managers and executives will increasingly need to anticipate trends in information management technologies that could affect their business. In health care, computer-based patient records, integration engines, online analytical processing systems, telemedicine, expert systems, and the Internet have become vital to having the competitive advantage. Those who do not understand the promise and limitations of these technologies and the need for strong leadership to establish standards for data and transaction systems will not lead their organizations well.  相似文献

虽然当前项目管理水平不断提高,但是企业信息系统项目实施的成功率仍然不容乐观。项目干系人缺乏准确的相互认知和角色定位,以及风险与控制的关系无法有效处理是导致项目绩效偏低的重要原因。为了从不同视角探索风险和控制对企业信息系统项目绩效的共同作用,通过对65位项目经理和63位用户代表所经历的128个项目的调查,利用结构方程模型进行实证分析,并采用层次回归分析技术进行检验。实证结果表明,正式控制和非正式控制对信息系统项目绩效都具有积极的影响,但是项目经理认为正式控制具有更加重要的作用,而用户代表认为非正式控制的作用更为显著。此外,项目经理和用户代表均认为组织风险和技术风险会减弱正式和非正式控制对绩效的有效作用。因此在控制方式的选择和组合上不仅要基于项目自身的特点,而且要基于干系人的角色。同时,信息系统项目绩效并非单纯由成功或失败因素所决定,而是取决于两类因素的均衡程度。研究结论为信息系统项目的风险控制提供了全新的理论依据和决策支持。  相似文献

Prior literature has examined product quality and service quality separately as antecedents of customer loyalty. In the context of the automotive industry, we present a framework that examines the simultaneous impact of product and service quality on consumers' purchase intentions. The framework is operationalized as several hypotheses that posit relationships between service quality, service satisfaction, product quality, and customer loyalty. The hypotheses are tested using three sources of data: (i) archival data on product quality and customer purchases, (ii) consumersíresponses to a survey instrument, and (iii) Consumer Reports. Results indicate general support for main hypotheses proposed.  相似文献

This paper deals with the economics of computer simulation applied to problems in the operations management/industrial engineering area. First, the material in the literature dealing with the economics of simulation is summarized. However, the amount of information available on the economics of simulation is very small. A number of hypotheses are presented for this paucity of material. Since many managers operate in an environment in which costs and benefits are relevant to their decision-making process, the lack of data on the economics of simulation may be a barrier to the utilization of the technique. In an attempt to improve this situation, a framework for the collection and specification of the economics of simulation modeling projects is proposed as a method of urging management scientists to begin to collect and publish data on the economics of simulation projects.  相似文献
