"Internal IT Knowledge and Expertise as Antecedents of ERP System Effectiveness: An Empirical Investigation"

Princely Ifinedo, Shannon School of Business, Breton University
Abstract
The literature shows that contingency factors such as organizational culture and structure, organization size, top management support, external expertise, and internal support are critical for the effectiveness of Enterprise Research Planning (ERP) systems in adopting organizations. Research on the effect of in-house computer and information technology (IT) knowledge and expertise on the success of such packages is rare. The purpose of this study is to explore the influence of computer/IT skills as antecedents of ERP system effectiveness. Using relevant theoretical foundations, a research model is developed to test eight relevant hypotheses. Data were collected in a cross-sectional field survey of 109 firms in two European countries. The partial least squares (PLS) technique is used for data analysis. The PLS results confirm six of the eight hypotheses. The study's conceptualization supports the view that in-house computer/IT skills are indeed pertinent to ERP system success in adopting organizations. A discussion of research results' implications for practice and research conclude this study.

Keywords: Computer knowledge; Enterprise Resource Planning (ERP); ERP post-implementation success; ERP system effectiveness; IS success evaluation; IT professionals' skills; Structural equation modeling

"Toward Mass Customized Product Deployment in E-Commerce: The Modularization Function and Postponement Strategy"

Chuan-Jun Su, Industrial Engineering & Management Department, Yuan Ze University
Hsin-Chi Chuang, AU Optronics Corporation

Abstract
Strategically deploying customized products in an e-commerce environment not only helps businesses respond with greater agility to customer needs and strengthen their market position, but also helps businesses gain a competitive edge and increase profitability. Underlying successful mass customization within the digital marketplace, a firm needs a methodology for striking a balance between the degree of customization and product pricing and delivery time-a critical supply chain issue. Providing either too much or too little customization can negatively impact both the business and the customer.

This study introduces a decision-making method for product customization. This method takes into account the level of customization, production costs, and product delivery time and it applies the concept of postponement strategy to the product supply chain to boost overall supply chain effectiveness and customer satisfaction. Bicycle customization is used as an example to demonstrate the feasibility of the new approach to determine an optimal level of customization in product deployment.

"Online Information Tools in Industrial Purchasing: An Exploratory Analysis of the Process of Business-Service"

M. Jose Garrido, Department of Management and Marketing, University of Valladolid

Abstract
This study explores how various stages of the purchasing process, and specific aspects of purchasing, impact the use of various Internet tools during a firm's procurement process. The hypotheses of this research are applied to a business service's purchase process. Information was gathered through a survey e-mailed to a sample of 103 industrial firms in Spain. Managers responded to a series of questions related to the purchasing of a service that had been acquired by their firm. The findings reveal that the novelty of the service for the organization, pressure due to time constraints to make a service-purchase decision, and individuals' personal stakes in a service-purchase decision lead to an increase in Internet use in the purchasing process. Furthermore, the results show that the buying phase has a significant impact on the intensity of Internet tool use in service procurement. When purchasing services, firms must take advantage of the benefits the Internet has to offer as a channel for distribution and communication. Firms selling their services through the Internet should focus particular attention on the design of their web pages. This work is one of the first to explore service purchasing through the Internet. Moreover, it is based on a sample of firms and on the acquisition of a wide range of differing services, and is not confined to just one, as is frequently the case.

"Conditional Role-Involved Purpose-Based Access Control Model"

Md. Enamul Kabir, Department of Statistics, University of Dhaka
Hua Wang, Department of Mathematics & Computing, University Southern Queensland
Elisa Bertino, Department of Computer Science, Purdue University
Abstract
This paper presents a conditional role-involved purpose-based access control (CPAC) model, where users dynamically activate conditional roles in accordance with the context attributes. Based on conditional role, access permissions are assigned that represent what can be accessed for what purpose to roles under certain conditions. On the other hand, conditional purpose is applied along with allowed purpose and prohibited purpose in the model. It allows users using some data for certain purpose with conditions (for instance, Tony agrees that his income information can be used for marketing purposes by removing his name). The structure of a CPAC model is defined and investigated. Access purpose is verified in a dynamic behavior, based on user attributes, context attributes, and authorization policies. Intended purposes are dynamically associated with the requested data object during the access decision. An algorithm is developed to achieve the compliance computation between access purposes and intended purposes and is illustrated with role-based access control (RBAC). Access purpose authorization and authentication in the model are studied with the hierarchical purpose structure. The model separates authorization of access purpose from access decision that improves the flexibility of private data control.

Keywords: Access control, Privacy, Purpose, Role-based access control (RBAC), Conditional role-involved purpose-based access control (CPAC)
