In recent years, e-learning system has been adopted as a training tool in many firms, as it can help employees to complete training in a short time and at a low cost. Within this context, since 2003 the Industrial Development Bureau (IDB) of the Ministry of Economic Affairs (MOEA) in Taiwan sponsored more than 50 enterprises each year to help them implement customized e-learning systems. Past research on e-learning mostly focused on one criterion and adopted regression approach, such as examining the relationships between satisfaction or continued usage intentions and various antecedent factors. Although the regression method could uncover the significant factors of e-learning adoption, they can not show the can (weighting) of each factor, and thus firms cannot allocate the optimal levels of resources. To overcome this problem, this study collected factors related to firms implementing customized e-learning systems from a review of the literature and expert opinions, and then constructed a hierarchical factor table. Based on the appropriateness and independence of factors, and as assessed by experts in the project promotion office of the IDB, e-learning solution providers and project leaders of the IDB sponsored enterprises, this paper then designed an Analytical Hierarchy Process (AHP) format questionnaire and sent it to these same experts to gather their responses. The factor weightings were derived based on the Fuzzy Analytic Hierarchy Process (FAHP) method. Finally, analysis of key factors was performed and recommendations provided. Based on the results for this work, service industry firms with limited resources can achieve proper resource allocation and more quickly and successfully adopt customized e-Learning systems.

Voice over IP (VoIP) is a promising low‐cost voice communication over the wireless IP network. To provide satisfactory VoIP services, the Quality of Service (QoS) of the wireless network should be guaranteed. This paper proposes a VoIP performance measurement freeware called NCTU VoIP Testing Tool (NCTU‐VT). We compare NCTU‐VT with two commercial tools SmartVoIPQoS and IxChariot in terms of packet loss, latency, and Mean Opinion Score (MOS) of the VoIP sessions in Wi‐Fi network. Our study indicates that these three tools can accurately measure VoIP performance in Wi‐Fi environment. Copyright © 2010 John Wiley & Sons, Ltd.
