Understanding the successful adoption of information technology is largely based upon understanding the linkages among quality, satisfaction, and usage. Although the satisfaction and usage constructs have been well studied in the information systems literature, there has been only limited attention to information and system quality over the past decade. To address this shortcoming, we developed a model consisting of nine fundamental determinants of quality in an information technology context, four under the rubric of information quality (the output of an information system) and five that describe system quality (the information processing system required to produce the output). We then empirically examined the aptness of our model using a sample of 465 data warehouse users from seven different organizations that employed report-based, query-based, and analytical business intelligence tools. The results suggest that our determinants are indeed predictive of overall information and system quality in data warehouse environments, and that our model strikes a balance between comprehensiveness and parsimony. We conclude with a discussion of the implications for both theory and the development and implementation of information technology applications in practice

In general, perceptions of information systems (IS) success have been investigated within two primary research streams—the user satisfaction literature and the technology acceptance literature. These two approaches have been developed in parallel and have not been reconciled or integrated. This paper develops an integrated research model that distinguishes beliefs and attitudes about the system (i.e., object-based beliefs and attitudes) from beliefs and attitudes about using the system (i.e., behavioral beliefs and attitudes) to build the theoretical logic that links the user satisfaction and technology acceptance literature. The model is then tested using a sample of 465 users from seven different organizations who completed a survey regarding their use of data warehousing software. The proposed model was supported, providing preliminary evidence that the two perspectives can and should be integrated. The integrated model helps build the bridge from design and implementation decisions to system characteristics (a core strength of the user satisfaction literature) to the prediction of usage (a core strength of the technology acceptance literature)

Past studies on ‘core competence’ have deliberated either on the theoretical concept of core competence or its usefulness as a strategic tool for firms. In spite of a large number of papers on the subject, to the author’s knowledge, there has been no study which spells out an actionable framework for leveraging the concept of core competence in creating competitive advantage for organizations. This perceptible gap in strategy literature is the prime motivation for this study. In this paper, the author views core competence as a ‘dynamic learned resource’ which is subject to continuous metamorphosis with changes in internal and external environment. The proposed ‘critical competence’ framework integrates the various studies on core competence and puts forth an all-encompassing practicable methodology to be utilized by firms for sustained success. Critical competence is the ability of a firm to successfully identify, nurture, develop, upgrade, and deploy its hierarchy of competencies to attain sustainable competitive advantage. In the process of proposing and explaining the framework for critical competence, this paper makes four major contributions:¾ First, it provides a consolidated and comprehensive literature review on the subject of core competence which can be used by academics for future studies on the subject.¾ Second, the proposed framework for critical competence shows that the possession of meta/ core competencies will in itself not result in competitive advantage; rather, it is important to understand how these competencies are utilized for adding value to the firm.¾ Third, the proposed critical competence framework serves as a tool for analysing the past success/failure and also serves as a guide for charting out the future strategy of firms. ¾ Fourth, through the example of Indian Railways, the paper illustrates the ‘descriptive capability’ of the proposed critical competence framework. The proposed framework helps us conclude that competencies in an organization need to be continuously nurtured, developed, and also abandoned. Critical competence emerges as a universal competence which is at the highest level in the hierarchy of competencies and is a prerequisite for attaining sustainable competitive advantage

Keywords Plus: INVENTORY POLICIES; DEMAND; SUBSTITUTION; MANAGEMENT; SYSTEMS Abstract: The role of remanufacturing as a competitive tool for firms has been reflected in a number of studies to show that remanufacturing can reduce the unit cost of production by reusing components. However, the fact that remanufacturing can be used as a strategic tool for serving secondary markets as well has not been acknowledged in the literature. In this paper, we study the use of remanufacturing as a tool to serve secondary markets. Specifically, we model the case of a reseller who procures used products based on an older generation of technology from an advanced market and then uses one of two options: (a) she can either resell a small fraction of these used products in a developing market where the technology is acceptable, or (b) she can invest in the remanufacturing of these products and then sell them in the developing market at a higher price. The main result of the paper is that using remanufacturing to serve secondary markets reduces the number of units procured from the advanced market for the reseller. In addition, we show based on certain cost structures that the reseller is always better off if she uses remanufacturing to a certain extent.
