摘要：As the widespread use and company dependency on expert systems (ES) increase, so does the need to assess their value and to ensure implementation success. This study identifies and emprically tests eight major variables proposed in the literature as determinants of ES success, in this case measured in terms of users satisfaction. IBM's Corporate Manufacturing Expert Systems Project Center collected information from 69 project managers to support the study. The results clearly support the hypot...

摘要：The concept of IT as a powerful competitive weapon has been strongly emphasized in the literature, yet the sustainability of the competitive advantage provided by IT applications is not well-explained. This work discusses the resource-based theory as a means of analyzing sustainability and develops a model founded on this resource-based view of the firm. This model is then applied to four attributes of IT-capital requirements, proprietary technology, technical IT skills, and managerial IT skil...

摘要：This study was motivated by the existence of two opposing schools of thought on managing information technology (IT) in a global context. One study proposes that managing IT in a global context is largely the same as managing IT in a domestic context. The other proposes that there is a difference. The results from interviews with 65 project managers, of whom 27 had international management experience, reflect a reality that lies somewhere between the two extremes. Using Q-methodology technique...

摘要：A key concern in Information Systems (IS) research has been to better understand the linkage between information systems and individual performance. The research reported in this study has two primary objectives: (1) to propose a comprehensive theoretical model that incorporates valuable insights from two comple mentary streams of research, and (2) to empirically test the core of the model. At the heart of the new model is the assertion that for an information technology to have a positive imp...

摘要：Changes in the knowledge and skill requirements of information systems (IS) positions were examined by analyzing the content of advertisements for IS professionals placed in four major newspapers over the 20-year period 1970-1990. Three types of jobs were examined: programmers, systems analysts, and IS managers. The analysis of the frequency of phrases in these advertisements suggests that job ads for programmers have changed very little-technical requirements remain high, and business and sys...

摘要：Information technology (IT) projects can fail for any number of reasons and in some cases can result in considerable financial losses for the organizations that undertake them. One pattern of failure that has been observed but seldom studied is the IT project that seems to take on a life of its own, continuing to absorb valuable resources without reaching its objective. A significant number of these projects will ultimately fail, potentially weakening a firm's competitive position while siphon...
