Empirical Research of Decision-making Effectiveness When Using Differing Presentation Formats Under Varying Decision Tasks

Empirical Research of Decision-making Effectiveness When Using Differing Presentation Formats Under Varying Decision Tasks

Date: December 1988
Creator: Hard, Nancy J. (Nancy Jean)
Description: The purpose of this research was to determine if presentation format, given a particular task to be performed, would affect the decision-making process of financial decision makers. The problem motivating this study is the potential for managers to make inefficient decisions when they use reports which are presented inappropriately for a given task.

The Organizational Consequences of Information Deployment

The Organizational Consequences of Information Deployment

Date: December 1991
Creator: Remington, William S. (William Seth)
Description: This study investigates the influence that increasing end user autonomy has on organizational data models. The independence offered by microcomputer technology offers users increasing independence in their information-handling activities. As independence increases, uniformity of data models across the organization is theorized to diminish. The problem motivating this study is the potential for improper allocation of resources that may result from a misinterpretation of organizational data. This study suggests that the expanding use of microcomputers in the business setting will contribute to diversity of data models. This may eventually lead to confusion and even lack of confidence in the information produced.

An Empirical Investigation of Detail Design Tools and Cognitive Style of Software Developers

An Empirical Investigation of Detail Design Tools and Cognitive Style of Software Developers

Date: May 1992
Creator: Flores-Rosales, Oscar
Description: The purpose of this study is to identify what detail design tools are more productive for the different types of professional software developers. By establishing a match between the detail design tool and the cognitive style of the professional programmer, the end product (Information Systems) should be of a higher quality. Two laboratory experiments were conducted. The first experiment was with professional Software Developers; the second one was with students. The dependant variables considered in this study were the number of semantic errors and the time required to complete a design task for conditional logic. The independent variables were the cognitive style of the subject, the complexity of the task, and the detail design tools. Decision trees, flowcharts and pseudocode were used as detailed design tools. Field dependence was the only dimension of cognitive style that was tested.

Productivity Considerations for Online Help Systems

Productivity Considerations for Online Help Systems

Date: May 1994
Creator: Shultz, Charles R. (Charles Richard)
Description: The purpose of this study was to determine if task type, task complexity, and search mechanism would have a significant affect on task performance. The problem motivating this study is the potential for systems online help designers to construct systems that can improve the performance of computer users when they need help.

Robustness of Parametric and Nonparametric Tests When Distances between Points Change on an Ordinal Measurement Scale

Robustness of Parametric and Nonparametric Tests When Distances between Points Change on an Ordinal Measurement Scale

Date: August 1994
Creator: Chen, Andrew H. (Andrew Hwa-Fen)
Description: The purpose of this research was to evaluate the effect on parametric and nonparametric tests using ordinal data when the distances between points changed on the measurement scale. The research examined the performance of Type I and Type II error rates using selected parametric and nonparametric tests.

A Case Study of the Use of Activity-Based Analysis as an Information Resource Management Tool

A Case Study of the Use of Activity-Based Analysis as an Information Resource Management Tool

Date: December 1994
Creator: Arnett, Charles A. (Charles Augustus)
Description: The purpose of the study was to investigate a modification of a managerial accounting technique, Activity-Based Costing (ABC), as a tool for addressing Information Resource Management (IRM) concerns within business processes. To indicate that ABC has been adapted for the IRM context, this study called the tool "Activity-Based Analysis" (ABA). ABA includes ABC's costing methodology as well as additional methods to address broader issues. The research method was a single-site case study at a property and casualty insurance company. The unit of analysis was a business process consisting of activities needed to provide claims handling services for workers' compensation insurance. Four questions guided the study: 1. Did ABA identify management information required to monitor process effectiveness and efficiency? 2. Did ABA support outsourcing decision making by identifying IRM cost components within business processes? 3. Did ABA identify information resources; that are sharable? 4. Did ABA identify differences between Company organizational characteristics andIRM department organizational characteristics?

Interactions of Presentation Formats and Decision-Maker Characteristics upon Multiple Decision-Making Tasks: an Experiment Using Multiple Cognitive Assessments

Interactions of Presentation Formats and Decision-Maker Characteristics upon Multiple Decision-Making Tasks: an Experiment Using Multiple Cognitive Assessments

Date: December 1994
Creator: Henson, Kerry L. (Kerry Lynn)
Description: Information systems research tends to ignore individual differences in users. This laboratory experiment sought to illuminate contributions of decision-makers' cognitive processes to decision outcome as reflected in four hypothesis sets: the impact of imagery preference and presentation format upon (HI) recall accuracy and upon hemispheric activation during (H2) encoding and (H3) recall, and (H4) to examine the relationship between hemispheric activation differences and accuracy differences. Point-value (specific values) and intraset-pattern (relationships between values) recall were considered. Thirty MBA students, grouped by imagery preference (cognitive style) as favoring verbal (textual) or visual (graphical) information presentation, performed computer-based recall tasks using tabular and graphical formats in a repeated measures design. Hemispheric activation (cognitive process) was assessed using ratios of EEG activity in six frequency bands captured from six pairs of homologous electrode sites during encoding and recall.

An Examination of the Effect of Decision Style on the Use of a Computerized Project Management Tool

An Examination of the Effect of Decision Style on the Use of a Computerized Project Management Tool

Date: August 1997
Creator: Fox, Terry L., 1963-
Description: Managing a software development project presents many difficulties. Most software development projects are considered less than successful, and many are simply canceled. Ineffective project management has been cited as a major factor contributing to these failures. Project management tools can greatly assist managers in tracking and controlling their projects. However, project management tools are very structured and analytical in nature, which is not necessarily supported by decision-making styles of the managers. This research examined the influence that decision style has on a project manager's use of a project management tool.
