The Impact of Task Complexity, Task Motivation, Decision Support System (DSS) Motivation, and DSS Use on Performance

چکیده
This study provides insight into the inconsistent findings on the impact of task complexity on performance by identifying the mediating role of task motivation in the effect of task complexity on DSS motivation and the interactive impact of DSS motivation and DSS use on performance. A research model is proposed to test the mediating and interaction hypotheses. One hundred participants use an experimental DSS application designed for the purpose of this study to complete a rating and selection task. Participants are randomly assigned to a high or low task motivation condition and a high or low task complexity condition. The DSS measures incorporates the accurate additive difference compensatory decision strategy, cognitive effort associated with use of this effortful strategy is attenuated. The partial mediating effect suggests that enhanced task motivation explains the positive effect of task complexity on DSS motivation. In addition, the results reveal that increased DSS use and enhanced DSS motivation lead to improved performance. The results have important implications for DSS research and practice.

Motivational Framework: Insights into Decision Support System Use and Decision Performance
The purpose of this chapter is to discuss how characteristics of a decision support system (DSS) interact with characteristics of a task to affect DSS use and decision performance. This discussion is based on the motivational framework developed by Chan (2005) and the studies conducted by Chan (2009) and Chan et al. (2009). The key constructs in the motivational framework include task motivatio...
متن کاملA Study of the Relationship Between Decision Model Naturalness and Performance
Two objectives in the design of decision support systems (DSS) are to improve decision-malting performance and to use DSS modeling forms that are natural, that is, to adopt modeling paradigms that are congruent with decision makers’ conceptual models of decision tasks. By accomplishing the latter objective, a DSS should enjoy better conceptual ease of use and face validity. However, past resear...
متن کاملA DSS-Based Dynamic Programming for Finding Optimal Markets Using Neural Networks and Pricing
One of the substantial challenges in marketing efforts is determining optimal markets, specifically in market segmentation. The problem is more controversial in electronic commerce and electronic marketing. Consumer behaviour is influenced by different factors and thus varies in different time periods. These dynamic impacts lead to the uncertain behaviour of consumers and therefore harden the t...
متن کاملDecision Complexity Affects the Extent and Type of Decision Support Use
The increasing complexity of decision-making has emerged as a risk factor in clinical medicine. The impact that decision task complexity has on the uptake and use of clinical decision support systems (DSS) is also not well understood. Antibiotic prescribing in critical care is a complex, cognitively demanding task, made under time pressure. A web-based experiment was conducted to explore the im...

A value chain is a series of events that takes a raw material and with each step adds value to it. Global interest in the application of natural gas (NG) in production and transportation has grown dramatically, representing a long-term, low-cost, domestic, and secure alternative to petroleum-based fuels. Many technological solutions are currently considered on the market or in development, whic...
