摘要：This paper presents the findings of two studies that replicate previous work by Fred Davis on the subject of perceived usefulness, ease of use, and usage of information technology. The two studies focus on evaluating the psychometric properties of the ease of use and usefulness scales, while examining the relationship between ease of use, usefulness, and system usage. Study 1 provides a strong assessment of the convergent validity of the two scales by examining heterogeneous user groups dealin...

摘要：Microcomputer playfulness represents the degree of cognitive spontaneity in microcomputer interactions. Research on the general characteristic of playfulness has demonstrated relationships with measures such as creativity and exploration. Thus, with the widespread diffusion of computers in organizations, research in microcomputer playfulness can have significant practical implications for organizations. Five independent studies involving more than 400 participants provided initial evidence for...

摘要：The development of an information system is a social process involving users and systems analysts, carried out in an organizational setting. This paper presents a process model of user-analyst relationships to guide research into the social dynamics of system development. The model identifies antecedent conditions, encounters, episodes, and outcomes over the course of a project. The model asserts that established relationships between analysts and users will persist unless critical encounters ...

摘要：Existing algorithmic models fail to produce accurate software development effort estimates. To address this problem, a case-based reasoning model, called Estor, was developed based on the verbal protocols of a human expert solving a set of estimation problems. Estor was then presented with 15 software effort estimation tasks. The estimates of Estor were compared to those of the expert as well as those of the function point and COCOMO estimations of the projects. The estimates generated by the ...

摘要：Information systems security remains high on the list of key issues facing information systems executives. Traditional concerns range from forced entry into computer and storage rooms to destruction by fire, earthquake, flood, and hurricane. Recent attention focuses on protecting information systems and data from accidental or intentional unauthorized access, disclosure, modification, or destruction. The consequences of these events can range from degraded or disrupted service to customers to ...
