Copyright @ 2013 Elsevier B.V.Electronic service implementation (ESI) in the public sector attempts to improve efficiency, effectiveness, and transparency of governmental departments. Despite having provided the necessary infrastructure and investment, many governments have struggled to realise such aims due to the various forces that challenge implementation and institutionalisation. Using institutional theory as a lens, we explored the forces influencing the implementation and institutionalisation of ESI in the public sector. While our results reinforced previous research in IT implementation and organisational transformation, they showed that the dynamic nature of technology poses unanticipated pressures, and that these can impede the implementation and institutionalisation process
The Impact of Decision Support Systems on the Effectiveness of Small Group Decisions - An Exploratory Study
This paper presents the results of an empirical investigation of the impact of Decision Support Systems on small group decision effectiveness. The study is conducted in the context of the Business Management Laboratory. Wolfe’s Business Management Laboratory Decision Support System (BMLDSS) was utilized to aid decision making by all treatment groups. Results indicate use of the BMLDSS did not lead to significantly superior performance as measured by financial performance variables. Further, no significant increase in satisfaction with or confidence in the decision making process could be attributed to the use of the BMLDSS
An Empirical Investigation Of Integrated Spatial-Proximity MCDM-Behavioral Problem Solving Technology Group Decision Models
This paper presents the results of an empirical test of two integrated spatial-proximity MCDM Behavioral Problem Solving technology models of group decision making. The performance of these models is compared to the performance of a non- integrated MCDM model for a strategic operations decision. The experiment is conducted in the context of the Business management Laboratory simulation game. Evidence relating to conflict in the decision making exercise is also discussed
The Impact of Decision Support Systems On The Effectiveness Of Small Group Decisions -Revisited
This paper presents the results of an empirical investigation of the impact of Decision Support Systems on small group decision effectiveness. The study is conducted in the context of the Business Management Laboratory. Two production function modules from Wolfe's Business Management Laboratory Decision Support System (BMLDSS) were utilized to aid decision making by all treatment groups. Results indicate the use of these modules improved decisionmaking performance in the second year of play as measured by manufacturing costs and Earnings/CGS. Debriefing indicated that two control groups developed informal DSS outside of the laboratory setting. Reanalysis of the performance data with this fact in mind indicated treatment groups' performance was superior to control groups' only for Earnings/CGS in the second year. The results of a questionnaire administration dealing with the subjects' feelings about the DSS are also discussed
Simulation Gaming As an Experimental Context for the Study Of Multicriteria Decision Making
While theoretical development of discrete multicriteria decision making (MCDM) models has proceeded apace over the last fifteen years, there has been a disappointing lack of empirical testing and validation studies. A major reason for this phenomenon is the unavailability of common decision making environments to serve as a context for such studies. This paper proposes simulation gaining as an experimental context for the study of multicriteria decision making. To illustrate the use of simulation gaming for this purpose, results of a study of two integrated MCDM-Behavioral models of group decision making conducted in tile experimental context of the Business Management Laboratory are presented
Quality improvement in an inventory model with finite-range stochastic lead times
Typically, traditional inventory models operate under the
assumption of perfect quality. In this paper we modify an
inventory model with finite-range stochastic lead time to allow
for a random number of defective units in a lot. However, there
is an extra cost for holding the defective items in the lot for
the period before it is returned to the supplier. This paper also
considers the option of investment to improve quality.
Closed-form relationships are obtained for a quality-adjusted
model as well as a quality improvement model. Numerical examples
confirm that the option of investment in quality improvement
results in significant cost savings. Sensitivity analysis shows
that the quality improvement model is robust
