The Impact of Top Management Commitment, Business Process Redesign, and IT Planning on the Business-to-Consumer E-Commerce Site

Managers and researchers would benefit from an understanding of the organizational practices that result in more featured e-commerce sites and of the particular features that contribute to firm performance. In a Web-based survey of 458 business-to-consumer e-commerce managers, CEO commitment and planning resulted in more featured sites whereas business process redesign did not. Four features, namely publishing applications, catalog applications, interactivity, and interfaces, predicted firm performance at a statistically significant level, while transaction applications and server performance did not. The research contributes by demonstrating the general importance of the organizational practices and site features, while raising questions about business process redesign, transaction applications, and server performance.     

Advancement,voluntary turnover and women in IT: A cognitive study of work–family conflict

We used quality of work life theory and the causal mapping method to evoke the concepts and linkages of women's cognitions about work–family conflict in order to better understand the issues contributing to advancement barriers and voluntary turnover of women in IT. The major concepts (Managing Family Responsibilities, Work Stress, Work Schedule Flexibility, and Job Qualities) were found to not only impact each other but also were key factors influencing women's advancement opportunities and voluntary turnover. Organizations may use these insights to mitigate voluntary turnover and increase workforce diversity by addressing female IT professionals’ concerns regarding work–family conflict issues.     

Micro- and macroergonomic changes in mental workload and medication safety following the implementation of new health IT

Health information technology (IT) is a promising way to achieve safer medication management in the delivery of healthcare. However, human factors/ergonomics dictates that in order to make the complex, cognitive work of healthcare delivery safer, health IT must properly support human cognition. This means, for example, that new health IT must reduce, not increase, workload during safety-critical tasks. The present study was the first to quantitatively assess the short- and long-term impact of bar coded medication administration (BCMA) IT on nurses' mental workload as well as on perceived medication safety. One-hundred seventy registered nurses across 3 dissimilar clinical units at an academic, freestanding pediatric hospital in the Midwest US participated in surveys administered before, 3 months after, and 12 months after the hospital implemented BCMA. Nurses rated their external mental workload (interruptions, divided attention, being rushed) and internal mental workload (concentration, mental effort) during medication administration tasks as well as the likelihood of each of three medication safety events: medication administration errors, medication errors on the clinical unit, and clinical unit-level adverse drug events. Clinical unit differences were assessed. Findings generally confirmed the hypothesis that external but not internal mental workload was associated with the perceived likelihood of a medication safety event. Comparisons of mental workload from pre- to post-BCMA revealed statistically significant changes in the critical care unit only. Medication safety appeared to improve over the long term in the hematology/oncology unit only. In the critical care and medical/surgical units, medication safety exhibited short-term improvements that were eliminated over time. Changes in mental workload and medication safety, two classically microergonomic constructs, were deeply embedded in macroergonomic phenomena. These included the fit between the BCMA system and the nature of nursing work, the process of BCMA implementation, and BCMA interactions with concurrent changes occurring in the hospital. Findings raise questions about achieving sustainable performance improvement with health IT as well as the balance between micro- and macroergonomic approaches to studying technology change.Relevance to industryDesigners must consider how technology changes cognitive work, including mental workload. Hospitals and other implementers of technology must ensure that new technology fits its users, their tasks, and the context of use, which may entail tailoring implementation, for example, to specific clinical units. Evaluators must look over time to assess both changes in cognitive work and implementation issues. Healthcare practitioners must also recognize that new technology means a complex transformation to an already complex sociotechnical system, which calls for a macroergonomic approach to design and analysis.     

A Philosophy of Information Technology and Systems (IT & S) as Tools: Tool Development Context, Associated Skills and the Global Technology Transfer (GTT) Process

It is the intent of this paper to discuss a philosophy of Information Technology and Systems (IT & S) as tools and the impact of this philosophy on the Global Technical Transfer (GTT) process of IT & S.It is argued that IT & S by definition, are artefacts, tools that have been made, used, inherited and studied within a cultural context which encompasses economic, historical, technical and social values and assumptions which are focussed in particular skill sets. It is assumed that these skill sets are mostly in evidence in any culture that receives the IT & S tool for use in a technical transfer process. It is argued, therefore, if we understand the cultural context in which a tool is made then we will understand the skills to transfer and use such tools in an effective manner. The issue we must face as makers, users, inheritors and scholars of IT & S tools, however, is that the tool context and inherent in-built values and skill sets, may not be in evidence across all cultures. This would make the effective use of IT & S, in a global sense, a difficult and complex (if not impossible) undertaking.From this position it is argued that IT & S tools reflect the IT & S discipline, as it is these tools which embody the assumptions of the discipline and hence, its paradigm. The Bunker and Dean (Bunker DJ, Dean RG. Philosophical Traditions in Information Systems: Challenger of an Interdisciplinary View, Faculty of Commerce Workshop, University of Wollongong, July 10--11, 1997) disciplinary model is highlighted as a means of understanding how tools are made within a cultural context and how they reflect the discipline in which they are created. This paper then goes on to explain the ramifications of IT & S as a discipline on the GTT process and proposes a skill-focussed approach, within a culture, to determining what IT & S may be appropriate for that particular cultural context.     

An empirical study of payment technologies,the psychology of consumption,and spending behavior in a retailing context

Our study investigates differences in spending behavior among consumers using three alternative payment technologies: cash, credit cards, and stored value contactless smart cards. We provide a deeper understanding of how different payment mechanisms directly impact consumer spending behavior in a retailing context, their influences on customers’ psychology of consumption, and perceptions of payment technologies. We show that the payment process can do so by significantly affecting the subjective awareness of spending only. In contrast, the source of money can affect perceived payment security only. Both perceived security and convenience have little effect on spending behavior.
