摘要:Decision support systems (DSS) often fail when their development lacks a thorough problem definition and/or an adequate commitment of individuals from the associated functional areas. A team-oriented structure for developing a DSS, like the one described in this article, can reduce such problems by outlining the tasks that managers, operating personnel, and information systems personnel should complete during the DSS's definition, design, and implementation stages.

摘要:This article questions the tacit assumption that computer software development is a homogeneous activity across differing tasks. The author proposes that conventional statistics on the performance of MIS software development groups are too often based upon norms and procedures relevant to groups developing systems-oriented software. To evaluate the statement a simple descriptive framework is presented which distinguishes software developmental attributes for MIS from those of other computer so...

摘要:This article explores the nature of cryptographic transformation and its application to the protection of data contained in files used by computer-based information systems. It presents some of the basic concepts of cryptography and structures of taxonomy of cryptographic transformations. The implications of computer oriented implementations of cryptographic protection are explored and the significance of such transformations for information systems is discussed.

摘要:This article describes a study of information system users in four Federal agencies in Washington, D.C., to determine associations between user behavior toward their systems and feelings toward the system staff, management support, and several other factors. The data was collected using a self-administered questionnaire.

摘要:This article proposes a major modification to the traditional systems development process. Traditional systems development approaches delay the delivery of tangible information system capabilities to users (i.e., query capabilities and decision support models, etc.) until the last stages of systems development. Consequently, it is not until after systems are developed that shortcomings in systems design surface. The authors advocate providing or at least simulating user capabilities early in t...
