A large number of studies have been conducted during the last decade and a half attempting to identify those factors that contribute to information systems success. However, the dependent variable in these studies-I/S success-has been an elusive one to define. Different researchers have addressed different aspects of success, making comparisons difficult and the prospect of building a cumulative tradition for I/S research similarly elusive. To organize this diverse research, as well as to present a more integrated view of the concept of I/S success, a comprehensive taxonomy is introduced. This taxonomy posits six major dimensions or categories of I/S success-SYSTEM QUALITY, INFORMATION QUALITY, USE, USER SATISFACTION, INDIVIDUAL IMPACT, and ORGANIZATIONAL IMPACT. Using these dimensions, both conceptual and empirical studies are then reviewed a total of 180 articles are cited and organized according to the dimensions of the taxonomy. Finally, the many aspects of I/S success are drawn together into a descriptive model and its implications for future I/S research are discussed.

Information Systems Success: The Quest for the Dependent Variable

The present historical moment may seem a particularly inopportune time to review Bowling Alone, Robert Putnam's latest exploration of civic decline in America. After all, the outpouring of volunteerism, solidarity, patriotism, and self-sacrifice displayed by Americans in the wake of the September 11 terrorist attacks appears to fly in the face of Putnam's central argument: that \"social capital\" -defined as \"social networks and the norms of reciprocity and trustworthiness that arise from them\" (p. 19)'has declined to dangerously low levels in America over the last three decades. However, Putnam is not fazed in the least by the recent effusion of solidarity. Quite the contrary, he sees in it the potential to \"reverse what has been a 30to 40-year steady decline in most measures of connectedness or community.\"' As an example of how the current \"war on terrorism\" could generate a durable civic renewal, Putnam points to the burst in civic practices that occurred during and after World War II, which he says \"permanently marked\" the generation that lived through it and had a \"terrific effect on American public life over the last half-century.\" 3 If Americans can follow this example and channel their current civic

What makes organizations so similar? We contend that the engine of rationalization and bureaucratization has moved from the competitive marketplace to the state and the professions. Once a set of organizations emerges as a field, a paradox arises: rational actors make their organizations increasingly similar as they try to change them. We describe three isomorphic processes-coercive, mimetic, and normative—leading to this outcome. We then specify hypotheses about the impact of resource centralization and dependency, goal ambiguity and technical uncertainty, and professionalization and structuration on isomorphic change. Finally, we suggest implications for theories of organizations and social change.

The IT implementation literature suggests that various implementation factors play critical roles in the success of an information system; however, there is little empirical research about the implementation of data warehousing projects. Data warehousing has unique characteristics that may impact the importance of factors that apply to it. In this study, a cross-sectional survey investigated a model of data warehousing success. Data warehousing managers and data suppliers from 111 organizations completed paired mail questionnaires on implementation factors and the success of the warehouse. The results from a Partial Least Squares analysis of the data identified significant relationships between the system quality and data quality factors and perceived net benefits. It was found that management support and resources help to address organizational issues that arise during warehouse implementations; resources, user participation, and highly-skilled project team members increase the likelihood that warehousing projects will finish on-time, on-budget, with the right functionality; and diverse, unstandardized source systems and poor development technology will increase the technical issues that project teams must overcome. The implementation's success with organizational and project issues, in turn, influence the system quality of the data warehouse; however, data quality is best explained by factors not included in the research model.

A multiattribute utility approach is adopted to assess the value of an information system. Various economic analyses of the value of information are reviewed and the conceptual problems regarding the definition of this value and some measurement difficulties are discussed. A list of possible utility attributes is proposed for a reporting system value assessment, and for each attribute a measure and a utility function is suggested. Some techniques which constitute a joint utility function are presented, accompanied by two examples. A real case of minicomputer selection is given in order to illustrate the structured approach.

The Israeli Air Force (IAF) has developed a simulation system to train its top commanders in how to use defensive resources in the face of an aerial attack by enemy combat aircraft. During the simulation session, the commander in charge allocates airborne and standby resources and dispatches or diverts aircraft to intercept intruders. Seventy-four simulation sessions were conducted in order to examine the effects of time pressure and completeness of information on the performance of twenty-nine top IAF commanders. Variables examined were: (1) display of complete versus incomplete information, (2) time-constrained decision making versus unlimited decision time, and (3) the difference in performance between top strategic commanders and mid-level field commanders.Our results show that complete information usually improved performance. However, field commanders (as opposed to top strategic commanders) did not improve their performance when presented with complete information under pressure of time. Time pressure usually, but not always, impaired performance. Top commanders tended to make fewer changes in previous decisions than did field commanders.

A severe problem in the processing of encrypted data is that very often, in order to perform arithmetic operations on the data, one has to convert the data back to its nonencrypted origin before performing the required operations. This paper addresses the issue of processing data that have been encrypted while the data are in an encrypted mode. It develops a new approach for encryption models that can facilitate the processing of such data. The advantages of this approach are reviewed, and a basic algorithm is developed to prove the feasibility of the approach.

This article discusses the findings of an empirical study conducted on 303 organizations. The major purpose of the study was to analyze the relationship between various organizational attributes and the deployment of hardware resources. The salient finding was that the most influential variable is the distribution of decision-making processes in the organization. The more decision making is distributed, the more hardware is distributed. No significant relationships were detected between hardware distribution and any of the following variables: organizational structure, economic sectorial association, and the size of the organization.
