There are decision support systems (DSS), executive information systems (EIS), artificially intelligent systems (AIS), and integrated combinations of these systems. Each of the individual systems supports particular phases and steps of the decision making process, but none of the individual systems supports the entire process in an integrated and

An effective e-business strategy is concerned with e-business multidimensional characteristics associated with different levels, parties, elements, and growth pattern features (Bakry & Bakry, 2001). In the process, the strategy must incorporate the effects of the instant and global Internet communication mechanism on the company’s business management architecture. The global reach and interconnectivity of the Internet have spawned new models of e-business strategy and radically transformed existing ones (Pant & Ravichandran, 2001). Indeed, what distinguishes many of the dot-coms is not their new technical power, but the radical new business models (Hamel, 2000). Aided by such innovative e-business models, managers will be able to identify the major decision factors involved in their business strategies and generate strategies that would improve their overall performance and profitability. In the current context, four essential perspectives are identified to be associated with an e-business strategy: financial, customer, internal processes, and learning and growth. These four perspectives were first introduced in early 1990s as the balanced scorecard concept (BSC) (Kaplan & Norton, 1992). Because the BSC methodology explicitly focuses on links among business decisions and outcomes, it is intended to guide strategy development, implementation, and provide reliable feedback for management control and performance evaluation. This BSC rationale is thereby appealing to managers who face new challenges in the current turbulent e-business climate. The real challenge is to determine how the BSC can be successfully applied in the context of e-business’s constantly changing environment of interdependencies (Hasan & Tibbits, 2000). E-business introduces new business objectives and strategies and the old measures of success may no longer apply. It is anticipated that the departure from the original BSC for a strategic e-business management framework would be more radical than the existing BSC adaptations (e.g., Martinson’s balanced IS scorecard; Martinsons, Davison, & Tse, 1999).

The advent of the Internet has resulted in a trend toward network centric computing. As a result, more of the computing work is delegated to the computer and the underlying systems. For many years, researchers have been working towards the development of shareable and re-usable problem-solving components to support decision-making. Internetworking technologies provide a new means of sharing decision support functionalities and delivering decision support capabilities. Corporate decision makers are not willing to cede control of corporate data and models to internet-based DSS, as a result enterprise-wide knowledge portals (corporate intranet-based DSS) has been developed to overcome this shortcoming. The Common Object Request Broker Architecture (CORBA) is one such integration approach. This paper describes how this approach can improve the enterprise decision support systems.

The theoretical foundations for this research is based on the decision making process. The emphasis of this research is on comparing the effectiveness of OOA to traditional approaches of software development (i.e., Structured Analysis (SA)). The argument is made that the effectiveness of a software development methodology depends on its ability to support the decision making process as it applies to software development. This research brings together two fields of literature: software engineering (SE) and decision support systems (DSS). The argument is made that many of the ideas and much of the research in DSS can be applied to the evaluation and development of methodologies. The experiment conducted for this research consisted of one group of subjects. The group was divided into two subgroups: groups A and B. All group members received instruction on the basic concepts of OOA and SA. All group members were asked to generate a requirements specification using each of the methodologies (OOA and SA) from cases drawn from the literature. In addition, each group produced a requirements specification without the aid of a traditional software development methodology (i.e., using the decision making process). A model of the decision making process was provided to the subjects for the "no traditional methodology" approach as a baseline control. Each "process" activity of decision making was measured by means of a questionnaire based on the phases of the DMP. The "outcome" metric was the quality of requirements specifications as measured by the panel of experts used to evaluate the requirements. Statistical tests were used to compare the effectiveness of each methodology at supporting the decision making process and overall effectiveness as measured by the quality of specifications. The results of this study showed that there was no advantage in using a specific software methodology to do requirements analysis. Further, the data from this study showed that using OOA is not any more effective an analysis approach than the more traditional approach of SA or "just" using a fully detailed DMP model.

Using statistical analysis of international survey data, the authors identify many differences between male and female managers' perceptions and attitudes. A significantly greater number of women than ever before have entered the work force over the past decade. Recent statistics from the Department of Labor indicate that the number of employed women in the United States has increased by 53 percent since 1970 and that women now comprise 43 percent of the workingpopulation. 1 Contrasting this figure with the same statistic for 1970, which shows women making up 37 percent of the work force, one can see the influx of women into employment over the past ten years. With continuing support of equal opportunity in employment legislation and changing social and economic conditions, there is every reason to believe that women will continue to enter the labor force during the 1980s. Accompanying women's increasingly greater role in the working world has been their steady move into managerial positions. It is the purpose of this article to look at women in management positions and assess their job satisfaction and motivation as compared to males in comparable positions. There is no conclusive proof that job satisfaction leads to increased performance. In fact, the literature reveals a very inconsistent relationship between these factors. However, job satisfaction and motivation are likely conducive to (and partially indicative of) a congenial employee attitude and work environment. It seems reasonable to assume that these conditions contribute to the organization's (as opposed to an employee's) performance. If so, it is important to 72

To achieve this housing goal, the Army must often enter into agreements for the construction of housing or for leasing of existing housing. Any housing construction or leasing request must be accompanied by a Segmented Housing Market Analysis (SHMA), a time‐consuming and costly forecasting process that requires many manual labor tasks. As described elsewhere, a Housing Analysis System (HANS) was developed to support these tasks on a micro computer with very user‐friendly computer programs. Recently, the original version of HANS has been modified and incorporated into a larger computer system now under development. At the heart of both the original and modified systems is a set of econometric and heuristic programming models that deliver the required analyses and evaluations. This paper describes these models, explains how they drive the modified HANS, and presents the results and benefits of the use of the modified computer system.Biographical Sketch — Guisseppi A.

In this article, we describe a balanced scorecard-based framework in detail and discuss its potential e-business uses. This framework enables e-business managers to plan and allocate resources more effectively and align strategic objectives with performance results. It also provides a stable point of reference for e-businesses to understand and manage the fundamental changes introduced by e-business initiatives.

For example, in practical implementations, it is rare to find a decision support system (DSS) without executive information system (EIS) capabilities or an expert system (ES) without a recommender system capability. Decision-making support system has become an umbrella term spanning a broad range of systems and functional support capabilities (Alter, 2004). Various information systems have been proposed to support the decision-making process. Among others, there are DSSs, ESs, and management support systems (MSSs). Studies have been conducted to evaluate the decision effectiveness of each proposed system (Brown, 2005; Jean-Charles & Frédéric, 2003; Kanungo, Sharma, & Jain, 2001; Rajiv & Sarv, 2004). Case studies, field studies, and laboratory experiments have been the evaluation vehicles of choice (Fjermestad & Hiltz, 2001; James, Ramakrishnan, & Kustim, 2002; Kaplan, 2000). While for the most part each study has examined the decision effectiveness of an individual system, it has done so by examining the system as a whole using outcome- or user-related measures to quantify success and effectiveness (Etezadi-Amoli & Farhoomand, 1996; Holsapple & Sena, 2005; Jain, Ramamurthy, & Sundaram, 2006). When a study has included two or more systems, individual system effects typically have not been isolated. For example, Nemati, Steiger, Lyer, and Herschel (2002) presented an integrated system with both DSS and AI (artificial intelligence) functionality, but they did not explicitly test for the independent effects of the DSS and AI capabilities on the decision-making outcome and process. This article extends the previous work by examining the separate impacts of different DMSSs on decision effectiveness.

Despite the many end user benefits of pervasive computing, the intrinsic instability and context ambiguities of these environments pose impediments to data-oriented decision support systems. In pervasive computing environments where users, systems, and computing resources are distributed or mobile, the online or “available” state of decision support-related resources may be intermittent or delayed. Awareness or knowledge of these resources’ online presence and availability can affect the decision making process. This article discusses issues related to data-driven decision support systems (DSS) in pervasive computing environments (PCE) and demonstrates that a decision maker’s awareness of online status and availability can improve decision outcomes. A model for extending DSS resource presence and availability awareness to decision makers is presented and the impact of this knowledge on decision outcomes is evaluated using a management problem simulation.
