Choosing Technology Majors: What You Don’t Know Can Influence You

This study explores high school graduates’ understanding of technology careers and reasons they choose not to major in technology fields. We employed two data collection methods (surveys and focus groups) in three data collection stages to explore student views in greater depth. Pre-survey and focus group results suggest that steps should be taken to provide a more enjoyable experience for high school students and teach them relevant skills that they will recognize as beneficial. Post-survey results demonstrate that introductory technology classes that introduce students to MIS careers can lead them to a more accurate understanding of MIS careers. The study offers insights into specific ways high school courses can be improved to increase understanding of MIS, resulting in a greater likelihood that students will consider and therefore choose technology careers. Findings suggest that increased understanding of technology careers can result in more consideration of these careers by high school students.     

Impact of information technology on users' work environment: A case of computer aided design (CAD) system implementation

Study of the possible impacts of a new information system or technology on its users is an important area of MIS research. Understanding and identifying favorable and unfavorable impacts of implementation on users should be helpful in developing better design guidelines and choices to take full advantage of the potential of information technology, while minimizing the possible negative consequences for users. This paper presents the details of impacts created by the implementation of a computer aided design (CAD) system for part designers at an automotive parts manufacturer. The paper employs equity–implementation (E–I) model as a framework to help identify and analyze the impacts of CAD technology implementation on part designers' work environment. The paper identifies changes in the designers' inputs and outcomes as a result of CAD implementation. On the whole the impacts were found to be favorable for designers, the manufacturing organization, and its customers. The paper concludes that the E–I model provides a useful framework to help assess the nature of impacts created by the new system. The reactions of designers to the new system were also found to be consistent with the E–I model.

Systems Support of Just-In-Time Manufacturing

In the current business environment, many organizations are turning to just-in-time (JIT) and total quality control (TQC) techniques to compete as effectively as possible. The MIS department can make an important contribution to the success of JIT by ensuring that the computer system supports its concepts effectively. To do this, however, MIS managers must understand exactly what a JIT system should and should not do. This article discusses the differences between JIT and traditional manufacturing and shows how computer systems can enhance the successful use of JIT techniques.

Innovative Computing with UNIX

Since its creation in 1969, the UNIX operating system has been used for such applications as telephone switching systems, transaction processing, office automation systems, artificial intelligence, and computer games. To make intelligent decisions about the application of UNIX-based systems, the MIS manager must understand the UNIX system in general, its strengths and weaknesses, and its applicability in various functional areas. This article discusses these aspects of UNIX and suggests how the MIS manager can introduce UNIX into the MIS department.     

A methodology for construct development in MIS research

This paper presents a comprehensive methodology for developing constructs in MIS research. It is applicable to both individual and organizational levels of analysis, depending on the nature of the concept under study. The methodology is presented as a research guide progressing through three stages: (1) domain definition, (2) instrument construction, and (3) evaluation of measurement properties. The methodology addresses six key measurement properties (content validity, factorial validity, reliability, convergent validity, discriminant validity, nomological validity), which are discussed in detail. An assessment of the proposed methodology indicates that its adoption in MIS research would greatly improve the rigor of construct development projects. This is evidenced by the wide range of quality publications that have used its techniques and its performance when compared to a number of prominent standards for assessing construct development research.

The Economics of UNIX

The emergence of a commercially feasible version of the UNIX operating system portends considerable change for the economics of both production and consumption in the MIS industry. UNIX has been around for 20 years and has drawn periodic attention from the MIS community, but the significance of this innovative operating system is just beginning to be felt among MIS professionals. Although it is tempting to dismiss UNIX as just another fad in information technology, the technical, economic, and social forces behind the UNIX innovation indicate that its effects will be far-reaching. This column discusses the origins and characteristics of UNIX, explores some important differences between UNIX and conventional operating systems, and presents the likely economic implications of the UNIX phenomenon for MIS management.

Variance tracking MIS in interdependent manufacturing contexts: An initial examination

There are many conflicting signals concerning the effectiveness of variance-tracking management information systems (MIS) in manufacturing contexts. Though there are anecdotal references to dissatisfaction with the systems and conceptual arguments concerning inaccuracy, no empirical evaluation of the effects of such system deficiencies could be found. This, combined with the widespread use of such MISs makes it of interest to further investigate them in manufacturing context. This paper provides an exploratory empirical examination of variance tracking MIS deficiencies. Via a simulation experiment, we find that, in an interdependent manufacturing context, variance-tracking MISs may severely misrepresent whether production departments are in or out of control. We thus agree with those who suggest that variance-tracking MISs may not be appropriate in interdependent manufacturing contexts. Contributions include an empirical demonstration of the kind and extent of MIS deficiencies that can occur in these contexts. However, the exploratory nature of this study imposes significant problems of external validity.     

Evolutionary database design and development in very large scale MIS

Developing flexible databases that can accommodate the changes and enhancements necessary in development of large scale Management Information Systems (MIS) is crucial to the success of the system and ultimately to the survival of the organization. Since the MIS is constantly being modified and enhanced, it is necessary for the database to be designed to adapt to change as it occurs. Numerous articles point to the need for large scale systems decomposition into smaller subsystems for implementation purposes. They also require an incremental development strategy which coincides with the database evolutionary strategy.This paper describes a methodology for large scale database development that assists MIS managers in building databases for large scale systems. It describes how these concepts were used for implementation of the US Air Force's largest distributed processing MIS—“The Requirements Data Bank” (RDB).
