Acceptance and Use of E-Learning Based on Cloud Computing: The Role of Consumer Innovativeness

Cloud computing and E-learning are the inevitable trend of computational science in general, and information systems and technologies in specific. However, there are not many studies on the adoption of cloud-based E-learning systems. Moreover, while there are many papers on information system adoption as well as customer innovativeness, the innovativeness and adoption in the same model seems to be rare in the literature. The study combines the extended Unified Theory of Acceptance and Use of Technology (UTAUT2) and consumer innovativeness on the adoption of E-learning systems based on cloud computing. A survey was conducted among 282 cloud-based E-learning participants and analyzed by structural equation modeling (SEM). The findings indicate that the adoption of cloud-based E-learning is influenced by performance expectancy, social influence, hedonic motivation, and habit. Interestingly, although innovativeness is not significant to use intention, it has a positive effect on E-learning usage which is relatively new in Vietnam.

Apply Agile Method for Improving the Efficiency of Software Development Project at VNG Company

Software engineering process (SEP) is more and more considered the key factor for any software company to create a better quality software with low costs and high productivity. However, there is a gap between theory and practice of applying modern SEP, such as Agile method, for improving the efficiency of software project management, especially for software companies in a developing country like Vietnam. VNG Corporation, a software company in Vietnam with a lot of small and medium web based software projects, currently meets many difficulties in ensuring the success of these projects. The current approach for software development is no longer consistent with the increasing requirements and flexibilities of these projects and VNG is going to find a new method for improving the efficiency of their software projects. In this research, Agile method is applied and tested to check whether it can be a suitable method for VNG to overcome their problems in software development. Besides, a testing project based on Agile method is also conducted at VNG company to evaluate the solution. Results showed that Agile method can help to increase customers’ satisfaction and it also helps to improve efficiency of project management by most KPIs.

Combination of Two KM Strategies by Web 2.0

The previous approaches for KM focused on either of two main strategies: Codification or Personalization (which focused on explicit or tacit knowledge, respectively). Those approaches lead to serious problems, such as: difficulty for integration, inconvenience in knowledge accessibility, limitation of participation, disjunction of knowledge... The approach for solving those problems of this paper is to set up a new integrated platform for combining both strategies. That platform is based on web 2.0, a set of advanced technologies and a new approach to knowledge management. Using web 2.0 for knowledge management, both kinds of knowledge can be supported at the same time and knowledge creating cycle is also facilitated. In this paper, a KMS based on web 2.0 is specified and a demo system is implemented for testing this solution, which shows many advantages in comparison with previous KMS.

Critical Success Factors for Implementing Business Intelligence System: Empirical Study in Vietnam

Although the application of business intelligence (BI) system has increased recently, the critical success factors (CSFs) of BI system implementation remain poorly understood. Therefore, understanding CSFs for BI system is necessary for a company to be successful in implementing a BI system. Currently, the number of business successfully implemented BI in Vietnam is still limited. In order to understand the current situation of BI implementation in Vietnam, case study method has been used. Based on the research framework developed by Yeoh & Koronios, in-depth interviews have been conducted with 4 Vietnamese companies, who already implemented BI system. The main result of this study helps to extract the lessons learnt from 4 cases to rank the importance of CSFs for BI implementation in Vietnam context. Based on this result, recommendations were made for increasing the probability of successfully implementing BI system in Vietnam and other countries with similar conditions.

The Impacts of Using SNSs on e-WOM and Knowledge Sharing Through Social Capital: An Empirical Study in Vietnam

Nowadays, Social Networking Sites (SNSs) have attracted billions of users all around the world. In Vietnam, SNSs become more and more familiar with Vietnamese people and Facebook is the most popular SNS. Social Capital is an important term in the study and social behavior, an important sector in the major universities of the world. However, Social Capital is still very vague concept, not only for citizens but also for policy makers in Vietnam. There are a few of studies have examined the impact of SNSs to Social Capital and Knowledge Sharing through word of mouth in environment of SNSs (e-WOM) in Vietnam. Based on previous research model, this research examines whether the intensity of using SNSs has a positive impact on users’ Social Capital, Knowledge Sharing and e-WOM. A survey was conducted with Facebook users in Vietnam. The regression analysis was utilized to examine the nine main hypotheses through a questionnaire designed which is based on the Likert five-point scale. The results show that the intensity of using SNSs raise the Trust and Identification dimension of Social Capital, especially the Trust, and these dimensions have positive effects to e-WOM Quality on SNSs. It also finds out that the e-WOM Quality impacts positively on Knowledge Sharing through SNSs environment in the context of Vietnam.

An empirical investigation of knowledge management in Vietnamese SMEs

Knowledge management (KM) is a discipline that improves the ability of companies in solving problem, adapt with changing in business, also helping them to gain and sustain their competitive advantages. This study is carried out with the objective to identify the measurement scale of KM practices, and to explore the impact of KM practice on the performance of small and medium enterprises in Vietnam. The data collection was analyzed by SPSS software with the sample size of 103. The participants are directors, managers and employees of Vietnamese SMEs. Analysis results showed that 3 main KM practices have positive impact on business success, including: Culture (0.321), Policy (0.099), and Knowledge acquisition (0.033), but the impact of Training on business success is not confirmed. The result also showed that there is a difference in understanding and applying KM across three categories of firm size: medium, small and very small enterprises. Some managerial implications have been suggested for managers of Vietnamese SMEs to enhance their performance based on KM approach in the future.
