Interorganisational Information Sharing and The Use of Decision Aids in Category Management

Most research on interorganisational information systems has primarily focused on systems that support transaction processing. What is less developed, however, is research on systems that provide interorganisational decision support. In this paper, we explore the effectiveness of these types of systems, by developing a model that introduces the relationship between interorganisational information sharing, decision aids and decisions effectiveness. Specifically, we propose that information sharing will positively influence decision effectiveness if filtering and analytical decisions aids are made available. Relevance and usefulness of the propositions are demonstrated within th

Multi User Decision Support System For Teachers Sertification With HTTPS

Education quality is a key condition to realize the life of a developed nation, modern dan Prosperous. (Fasli Jalal 2008) Teacher quality greatly affect the effectiveness of learning (Suherman, 2007, Rink, 2002). Teacher certification program is a way to improve the quality of teachers so that the quality of education will be increased dan in turn affect students' achievement (Siedentop & Tannehill, 2000). The purpose of this paper is to discuss the design of decision support systems passing teacher certification so as to facilitate the certification team dan assessors in the decision making sertikasi teacher graduation. In this paper we use a qualitative method based on system development life cycle (SDLC), including planning, analysis, design, dan implementation. Design of decision support systems passing teacher certification can provide information about passing the certification of teachers, as information analysis dan control in teacher certification assessment conducted by the assessor dan teacher certification of graduation information.

Use and effectiveness of decision support systems (DSS): Study of the Saudi private sector

In the industrialized world today, management is characterized by extensive use of computers to manage rapid change, information overload, and complex decision-making. Literature suggests that Decision Support Systems, computer packages offering information retrieval, problem-structuring models, decision alternatives, and other types of decision support, are effective extensions of human decision-making and offer substantial benefits to organizations utilizing them. In spite of overwhelmingly positive reviews for DSS, empirical literature has produced inconsistent results regarding DSS effectiveness, and definitions of “effectiveness” and of DSS itself are varied and sometimes contradictory. Distinguishing DSS from MIS (management information systems) and other types of managerial computer support has proven to be an essential part of DSS research. An additional gap in DSS research to date is that little is known about DSS use in developing countries and the potential of DSS to improve decision-making and overall organizational effectiveness. The present empirical study surveyed one member from each of Saudi Arabia\u27s largest corporations to determine to what extent DSS has been incorporated into the companies\u27 decision-making procedures. A second purpose was to determine decision-makers\u27 perceptions of the effectiveness of DSS in terms of their decision processes (time savings, availability of more alternatives, cognitive effort) as well as decision outcomes (decision accuracy and overall quality). The research revealed a high degree of use and enthusiasm for DSS, but revealed gaps in Saudi utilization of the systems. The research identified specific obstacles to more pervasive adaptation and enjoyment of benefits, including a lack of research stemming from researchers\u27 misperceptions of the private sector\u27s interest in and ability to understand Decision Support Systems

User Perceptions of Decision Support Effectiveness: Two Production Planning Experiments *

Decision support systems continue to be very popular in business, despite mixed research evidence as to their effectiveness. We hypothesize that what-if analysis, a prominent feature of most decision support systems, creates an “illusion of control” causing users to overestimate its effectiveness. Two experiments involving a production planning task are reported which examine decision makers' perceptions of the effectiveness of what-if analysis relative to the alternatives of unaided decision making, and quantitative decision rules. Experiment 1 found that almost all subjects believed what-if analysis was superior to unaided decision making, although using what-if analysis had no significant effect on performance. Experiment 2 found that decision makers were indifferent between what-if analysis and a quantitative decision rule which, if used, would have led to significant cost savings. Thus, what-if analysis did create an illusion of control: decision makers perceived performance differences where none existed, and did not detect large differences when they were present. In both experiments, decision makers exhibited difficulty realizing that their positive beliefs about what-if analysis were exaggerated. Such misjudgments could lead people to continue using what-if analysis even when it is not beneficial and to avoid potentially superior decision support technologies.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/73794/1/j.1540-5915.1994.tb00516.x.pd

Measuring the Effectiveness of Hypertext In Decision Support

Hypertext is an emerging technology that has not been researched adequately, particularly in organizations that utilize decision support technologies. This paper suggests that developing a set of dependent variables to measure effectiveness of hypertext in decision support is an important first step in a program of research. A review of empirical hypertext research is presented followed by a discussion of research assessing effectiveness of decision support and related systems. The role of hypertext in organizations is conceptually linked to the three main phases of the decision making process: problem structuring, analysis, and problem resolution. A set of six classes of appropriate dependent variables for assessing effectiveness of hypertext is suggested within the context of the decision making phases: information content and function variables are associated with problem structuring; presentation and usage variables are associated with analysis; outcome and perception variables are associated with problem resolution

Support for the Inclusion of Personal Value Preferences in Decision Support Systems

We consider the important issue of including personal value preferences in decision support systems (DSS). Various personal differences have been shown to affect the acceptance, use, and effectiveness of DSS. Decision-making models offer a theoretical basis for the inclusion of various personal differences (including personal value preferences) in decision-making. Research in the field of psychology has long recognized the importance of values in both motivation and choice behavior. Other research has also found personal values to be relevant in decision-making. We posit that since personal values are important in the decision-making process, they should also be important in the support of decision-making and thus in decision support systems
