Performance measurement integrated information framework in e-Manufacturing

The implementation of Internet technologies has led to e-Manufacturing technologies becoming more widely used and to the development of tools for compiling, transforming and synchronising manufacturing data through the Web. In this context, a potential area for development is the extension of virtual manufacturing to performance measurement (PM) processes, a critical area for decision making and implementing improvement actions in manufacturing. This paper proposes a PM information framework to integrate decision support systems in e-Manufacturing. Specifically, the proposed framework offers a homogeneous PM information exchange model that can be applied through decision support in e-Manufacturing environment. Its application improves the necessary interoperability in decision-making data processing tasks. It comprises three sub-systems: a data model, a PM information platform and PM-Web services architecture. A practical example of data exchange for measurement processes in the area of equipment maintenance is shown to demonstrate the utility of the model.

User preferences for web site attributes: A study of the Hong Kong Disneyland

The Hong Kong Disneyland will be open in 2005 and the theme park is very likely to have an official web site. In order to determine the nature of a model/ideal official web site that would serve the promotional purpose, this study is conducted with two objectives. First, the study makes an attempt to understand the information types that the target markets, namely local Hong Kong residents, Western visitors and Chinese visitors, would like to have on the future Hong Kong Disney web site. Secondly, this research examines whether e‐ticketing is feasible for the web site. Using a questionnaire and a convenience sampling method, 198 responses were received. Empirical results indicate that the respondents all agreed that the suggested attributes should be listed in the web site. In addition, no significant difference was found among different groups of respondents on homepage information. However, significant differences were found among the interviewees’ views regarding products/services information, and ticketing information. To communicate effectively, the adoption of EDI (Electronic Data Interchange) is recommended in a value‐chain system for achieving successful e‐commerce.     

UGIS: Understanding the nature of user-generated information systems

People from around the world are bringing together a variety of information technologies—devices, services, applications, networks, and information—to create personal information systems. This emerging phenomenon is enabled by a convergence of inexpensive, powerful, and ubiquitous devices and applications connected through global networks, motivated by an open ideology and enacted by ‘prosuming’ users. This article examines the phenomenon of the user-generated information system (UGIS) to better understand its origins and thereby describe its nature. A formal definition of UGIS is developed, and its components described. A model of the ideological and technical forces that contribute to the changing role of the user as information system creator, and to the emergence of this capability and issues, is introduced. Implications for managers are discussed.     

Does Social Software Support Service Innovation?

Recent Internet technologies and web‐based applications, such as social software, are being increasingly applied in firms. Social software can be employed for knowledge management and for external communication enabling access to internal and external knowledge. Knowledge, in turn, constitutes one of the main inputs to service innovation. Hence, social software has the potential to support service innovation. Using data from German IT and knowledge‐intensive service firms, this is the first paper that empirically analyses whether the use of social software applications triggers innovation. It refers to a knowledge production function in which social software use constitutes the knowledge sourcing activity. The results reveal a positive relationship between social software and service innovation. Since this result is robust when controlling for former innovative activities and the previous propensity to adopt new technologies and to change processes, the analysis suggests that the causality runs from social software to innovation.     

Thinking and feeling on the World Wide Web: the impact of product type and time on World Wide Web advertising effectiveness

This article focuses on the effectiveness of banner advertisements.Drawing from theory on functional versus expressive products and wear in versus wear out it argues that product type and time are important factors in World Wide Web (WWW) advertising. The results from a large empirical study are reported and show that responses to banner advertisements differ between functional and expressive products and over time. Functional product banner advertisements have higher initial click-throughs that quickly deteriorate and they have no effect through advertisement impressions. Expressive products need time to wear in as both click-through rates and positive brand attitudes from advertisement impressions increase with repeated exposures. These differences in consumer response are conceptualized as thinking and feeling on the WWW,thereby providing important implications for advertisers.
