This research advances the understanding of how to define, evaluate, and promote e-learning success from an information systems perspective. It introduces the E-Learning Success Model, which posits that the overall success of an e-learning initiative depends on the attainment of success at each of the three stages of e-learning systems development: system design, system delivery, and system outcome. To study this model, an online version of an undergraduate quantitative methods core course for business students is developed using a prototyping strategy. Four cycles of development are traced, each comprised analysis, design, implementation, testing, and enhancement. Findings from the study confirm the validity of using the proposed success model for e-learning success assessment. In addition, an action research methodology is also found to be a valuable impetus for promoting e-learning success through an iterative process of diagnosing, action planning, action taking, evaluating, and learning.

PurposeThe purpose of this paper is to provide a theoretical model of supply chain agility and, based on that, develop a research framework for investigating linkages between supply chain agility and firm competitiveness.Design/methodology/approachThe conceptual model of supply chain agility introduced here is based on an inter‐disciplinary literature review, which concentrates on peer‐reviewed journal papers on agility published within the period 1990‐2007. Among a total of 583 papers, representative studies are chosen and analyzed to identify key elements of supply chain agility, and to point out issues that have yet to be addressed.FindingsHe was found that even though there has been considerable research on the topic of agility, in general, there is relatively little examination of agility in the supply chain context. These few studies are not unified in their conceptualizations of agility and tend to adopt fairly limited views of supply chain dimensionality. This situation suggests that there is a need for a theory‐driven, unified model of agility in supply chains.Originality/valueThis paper fulfills an identified need for a comprehensive conceptual model of supply chain agility. Built from a work‐design perspective, this new conceptualization of supply chain agility offers a theoretical platform for guiding future research and practice concerned with achieving supply chain agility.

Purpose -The purpose of this paper is to develop an instrument to measure supply chain agility. Design/methodology/approach -The development of this supply chain agility scale utilizes an examination of supply chain agility literature, experience surveys, and expert judges. The result is a 12-item instrument with six dimensions. Findings -The instrument has been rigorously tested and validated, which generates a high degree of confidence in the scale's validity and reliability. Originality/value -This paper fulfills an identified need for the development of an empirically validated instrument to measure supply chain agility. This reliable and validated instrument enables and facilitates future studies in the supply chain agility research stream.
