The Role of Information Feedback in the Management Group Decision-Making Process Applying System Dynamics Models

The research project addresses the influence of feedback information on the decision process supported by the application of system dynamics models. A user-friendly application was developed and used in the experiment with decision groups. The participants were 174 undergraduate management science students. They had the task of determining the optimum business strategy by maximizing the multiple criteria function under three experimental conditions: a ₁) an indivIDual decision process without the support of a system dynamics model, a ₂) an indivIDual decision process supported by a system dynamics model, and a ₃) a decision process supported by a system dynamics model and subject interaction via computer mediation. The hypotheses that the indivIDual decision process supported by a system dynamics model yields higher Criteria Function values than one without a system dynamics model, as well as the decision process supported by both a system dynamics model and subject interaction yields higher Criteria Function values than one supported by a system dynamics model alone were confirmed.     

Electronic Meetings and Intense Group Conflict: Effects of a Policy-Modeling Performance Support System and an Audio Communication Support System on Satisfaction and Agreement

Ad-hoc decision teams were used to examine the effects of an electronic meeting system (EMS) on group satisfaction and agreement. The decision task provoked intense conflict of values. The EMS had two core features - a policy-modeling group performance support system (incorporating structured decision methods and computer-supported cognitive feedback using Multi-Attribute Utility Analysis and Social Judgment Analysis), and an audio-based group communication support system (allowed dispersed members to communicate by voice). Policy groups reached higher agreement than conventional decision-making groups, apparently due primarily to the structure for cognitive-conflict tasks that was imposed on group discussion rather than computer-supported cognitive feedback displays. Audio groups were more satisfied with the conflict process than face-to-face groups. Decision agreement was equivalent across the two media. These audio effects for a highly equivocal task represent a further challenge to media richness theory.     

Monte Carlo Simulation Techniques in a Decision Support System for Group Decision Making

This paper describes a group decision support system based on an additive multi-attribute utility model for identifying a consensus strategy in group decision-making problems where several decision-makers or groups of decision-makers elicit their own preferences separately. On the one hand, the system provides procedures to quantify the DMs or group of DMs preferences separately. This involves assessing the DMs or group of DMs component utilities that represent their preferences regarding the respective possible attribute values and objective weights that represent the relative importance of the criteria. On the other hand, we propose Monte Carlo simulation techniques for identifying a consensus strategy. An iterative process will be carried out, where, after the simulations have been performed, the imprecise component utilities and weights corresponding to the different DMs or groups of DMs are tightened to output more meaningful information in the next simulations to achieve a consensus strategy. Finally, an application to the evaluation of remedial strategies for restoring contaminated aquatic ecosystems illustrates the usefulness and flexibility of this decision support tool.     

Cognitive hurdles in the use of decision support systems to enhance problem understanding

Computer-assisted decision support systems have been widely promoted as a means of enhancing problem understanding in crisis and noncrisis decision making. Clinical observation of actual applications of a particular category of software for interactive decisions (CONAN, DECISIONMAKER) have identified cognitive hurdles in the use of such systems. These hurdles not only pose a challenge to the development of such normative interventions in the decision process, but also an opportunity for furthering the shift to a new psychologically informed paradigm for decision making.     

The Impacts of Affective and Cognitive Social Conflict in Business-to-Business Buyer-Seller Relationships: A Comparison of New versus Ongoing Buyer-Seller Relationships

ABSTRACT

Purpose. The purpose of this paper is to report empirical research that examined the impact of conflict in two different buyer-seller situations, an ongoing relationship and a choice situation where the buyer had to choose between two or more alternative suppliers. Conflict was defined as social conflict and has two distinct types, affective and cognitive.

Methodology/Approach. The methodology used was two mail surveys to a random sample of purchasing association members who had buying responsibilities in their firms. In one survey respondents were asked to self-select a current buyer-seller relationship they had for a period of at least one year and to indicate the degree of perceived conflict they had with the key supplier representative as well as the amount of relationship loyalty they perceived they had with that supplier. The second survey randomly assigned respondents to evaluate either a supplier whom they gave business to in a choice situation or one they did not, thus establishing as the dependent variable the actual choice of whom they gave business to.

Findings. The findings are clear for affective types of conflict. When affective conflict is perceived as higher the chance of getting an order in a choice situation as well as the magnitude of the relationship loyalty perception is negatively related. Cognitive conflict is not as clear. In choice situations conflict was negatively related to choice, whereas in on going relationships there was no impact. There was no indication of cognitive conflict having a positive relationship.

Originality/Value/Contribution of the paper. This study is the first to examine perceptions of conflict with a significant other in a buyer-seller relationship to try to determine how those perceptions might relate to either buyer choice or loyalty. While the findings support the expected relationship between affective conflict and outcomes, the findings with regards to cognitive conflict suggest that this may be more complex then originally thought and further points out the difficulty in managing conflict across organizational boundaries.     

The Effects of Media and Task on User Performance: A Test of the Task-Media Fit Hypothesis

This research was designed to examine the task-media fit hypothesis, an extension to media richness theory that predicts the objective performance of various media for a number of task types. To examine this model, dyads communicating through face-to-face, videophone, telephone (i.e., audio-only communication), or synchronous computer-mediated communication worked in a laboratory experiment to address an intellective or negotiation task. The intellective task required that each dyad member effectively share factual information that each individual independently held. The negotiation task required that each dyad member effectively share preferences based on personal values and reach an agreement. The results of the study provide mixed support for the task-media fit hypothesis. In general, the results for the negotiation task largely supported the theory while the results for the intellective task did not support the theory. These results help to clarify limitations and provide extensions to the theory by demonstrating how variations in task processes and communication media act to mediate task performance. The implications of these results for future research and practice are discussed.
