Assessing the Catalyst and the Barriers to Rural Community Based Telecentre Usage
Abdulwahab,L Zulkhairi Md Dahalin
Journal of Emerging Trends in Computing and Information Sciences , 2012,
Abstract: The success of telecentre implementation along the developing countries depends largely on identifying the factors that may spur or hinder users’ acceptance and use. The federal government in Nigeria projected that by the end of the year 2011; telecentre would be established in the entire country. However, despite this projection, limited empirical studies were conducted regarding the acceptance and use of telecentre in various communities in Nigeria. This research aimed at assessing the catalyst and obstacles regarding the telecentre usage. A total of 313 questionnaires were retrieved from the adopters and non adopters of telecentre in two communities of North East Geopolitical Zone of Nigeria. The finding shows positive correlation between the awareness of telecentre services with usage. Also, from the findings, the major barrier to the effective use of telecentre was attributed to the lack of awareness of services offered by the telecentre.
Effectiveness of Telecentre using a Model of Unified Theory of Acceptance and Use of Technology (UTAUT): Structural Equation Modeling Approach
Abdulwahab, L,Zulkhairi Md Dahalin
Journal of Emerging Trends in Computing and Information Sciences , 2011,
Abstract: In most of the developing countries, Telecentres’ have been set up in some unserved and underserved areas. The purpose of this initiative is to provide an avenue for communal access to reduce the effect of digital divide. Even though, Governments, NGOs’ and International Organizations are promoting these initiatives’, its acceptance and effectiveness are minimal. Therefore, this paper investigates the main determinants of user acceptance through a survey by gathering empirical evidence based on the revised Unified Theory of Acceptance and the Use of Technology (UTAUT). Data collected from 182 respondents in Nigeria were tested against the research model using the structural equation modeling approach. The proposed model fits the data well. Results show that, User acceptance of Telecentre was demonstrated by performance expectancy; social influence, management effectiveness, program effectiveness and facilitating conditions. The findings of this research provide implications for the research and practice of Telecentre development and implementation in developing countries.
Applying the Triangulation Approach in IT – Business Strategic Alignment and Sustainable Competitive Advantage
Dmaithan Abdelkarim Almajali,Zulkhairi Md Dahalin
IBIMA Business Review , 2011,
Abstract: While researchers have encouraged more research on the causal chains between information technology investments and Business performance, the results of empirical studies have been inconclusive. This is partly due to the exclusion of IT-business strategic alignment. This study has examined the impact of IT-business strategic alignment antecedents in terms of leadership, structure and process, service quality, and value and belief on IT business strategic alignment in terms of alignment gap, followed by the impact of IT-business strategic alignment on sustainable competitive advantage. In order to explore the above research relationships, the study further utilizes the positivism paradigm by applying a mixed research method both quantitative and qualitative data. Such triangulation would help to provide more insight into the issues studied in this research. Particularly, this study has tested the research model by conducting 172 survey questionnaires with public shareholding firms in Jordan. After that, the study conducted several follow-up interviews in Jordan in order to further validate the research results. Thus, the results obtained from the structural equation modeling (SEM) technique and supplementary qualitative analysis of the interviews offer a valuable insight into the research. However, the universal applicability of this research may be limited due to the fact that the results are based only on the cross-sectional data from the Jordanian public shareholding firms. Consequently, further research is needed with regards to several countries since this would help to advance understanding of the IT-business strategic alignment issue and the conditions and outcomes of achieving it in different contexts.
Using Business Process Re-engineering to Increase Process Efficiency of E-Catalogue Distribution System
Zulkhairi Md Dahalin,Siti Fatimah Yusof
IBIMA Business Review , 2012,
Abstract: The traditional printed paper based product catalogue is restricted to customers and places, which is difficult to handle in addition to time and cost of printing, storage area and shipping. Thus, this study attempts to present the results of a business process re-engineering of a direct selling catalogue distribution that is able to eliminate such physical limitations and enable the distribution business process to become more efficient. Incorporating e-catalogue as an outcome of the business process re-engineering shows that the business process can be simplified from 32 activities to 13 activities. With this approach the percentage of process efficiency rate for business process selected has been increased dramatically from 20% up to 86% and also reduced the waiting rate from 55% to 7%. In order to rate the usefulness of the e-catalogue solution, 30 respondents from direct selling dealers were selected to test the e-catalogue prototype. The final result indicates that business process re-engineering has the capability to simplify a fairly complex manual and paper-based processes, resulting in a better, more efficient e-catalogue distribution system.

Factors influencing IT-Business Strategic Alignment and Sustainable Competitive Advantage: a Structural Equation Modelling Approach
Dmaithan Abdelkarim Almajali,Zulkhairi Md Dahalin
Communications of the IBIMA , 2011,
Abstract: Preceding research attributed the lack of direct causal impact of Information Technology (IT) on firm’s sustainable competitive advantage. Numerous missing links include antecedents of the IT-business strategic alignment (also known as strategic alignment) and the sustainable competitive advantage. Furthermore, reviewers of recent literature have called for more research into the factors that affect strategic alignment, and the linkage between alignment and sustainable competitive advantage. In this paper, we develop and empirically test specific forms of management structures and processes which are required to drive strategic alignment. Further, we propose a causal-chain model to examine the impacts of six antecedents on strategic alignment. The data are collected from over 172 Jordanian public shareholding firms. Using structural equation modeling for data analysis, this study finds general support for the hypotheses that leadership, values and belief, IT managerial resources, service quality, and IT implementation successes significantly impact IT-business strategic alignment. However, no relationship is found between structure and process and strategic alignment.
Financial Sustainability Issues in Malaysia’s Telecentres
Huda Ibrahim,Azman Yasin,Zulkhairi Md Dahalin
Computer and Information Science , 2010, DOI: 10.5539/cis.v3n2p235
Abstract: Telecentre plays an important role in bridging digital divide in Malaysia. A study was conducted on 132 telecentres to identify the issue of financial sustainability. Questionnaires were sent to telecentres’ operators and users. The results show that financial support is critical in operating centers. High investment is needed not only to run telecentre but also to maintain it. The costs incurred in running telecentres involve costs for promotion, staff, utilities, premise renting, and training. More than 75 percent of all telecentres are operating under tight cash budget. Strategies for financial sustainability and collaboration are recommended to sustain TCs in the future.
An Enterprise Architecture Methodology for Business-IT Alignment: Adopter and Developer Perspectives
Zulkhairi Md. Dahalin,Rafidah Abd Razak,Huda Ibrahim,Nor Iadah Yusop
Communications of the IBIMA , 2011,
Abstract: This paper proposes the use of an enterprise architecture methodology known as the Systemic Enterprise Architecture Methodology to determine the relevance of EA in addressing the business-IT alignment. A construct that characterized EA was developed based on review of the literature. A theoretical framework build upon the Systemic Enterprise Architecture Methodology (SEAM) was used based on a business-IT alignment market, in which supplier business systems compete to provide a value to an adopter business system. Data was empirically gathered based on survey respondents who are concerned with the adoption, planning and implementation of EA in their organizations. Respondents were managers and executives representing the IT and senior level management of public and private organizations in Malaysia. The data collected was then analyzed based on the following factors: (1) EA business issues; (2) EA environment; (3) EA governance; and (4) EA methods, tools and frameworks. Comparative analysis was carried out based on the four factors to examine the trend and status of EA adoption and implementation in Malaysia vis-à-vis the international scenario. Statistical analysis was used to validate the SEAM, which was found to be relevant in addressing the business-IT alignment.

Abstract: Many organizations in Jordan are currently frustrated with the benefit and value obtained from their investment in IT. An understanding of why Jordanian organizations do not benefit from IT investment can assist these organizations to explore the factors that organizations use to align IT with their business objectives. In-depth qualitative interviews with IT managers in Jordanian organizations suggest that leadership, structure and process, service quality and values and belief are the most important factors which are representative of the culture gap between IT strategy and business strategy. The lack of these factors hinders organizations from gaining benefits from their investment in IT. From the findings of this study, it is found that the alignment gap is often used to explain or justify an organization’s inability to effectively leverage on IT.

Zulkhairi Rizlan,Othman Mamat
Chinese Journal of Engineering , 2014, DOI: 10.1155/2014/802459
Abstract: Experiments are designed using Taguchi method to find the optimum parameters for silica sand nanoparticles production using low speed ball milling. Orthogonal array and signal-to-noise ratio are applied to study performance characteristics of machining parameters which are the ball to powder weight ratio, volume of milling jar, and rotation speed. Results obtained from signal-to-noise ratio analysis showed that ball to powder weight ratio is the most influential parameter. 1. Introduction Nanoparticles of silica sand have been researched progressively and produced due to the unique features as a result of size reduction. Silica sand nanoparticles have proved to be a very effective additive to polymers by improving durability, strength, and flexibility. Nanosilica is also used as an additive to improve strength and workability of self-compacting and high performance concretes. Nanosilica particles are widely produced by chemical processes. However, chemical synthesis of nanosilica produces high contamination in the final products. As the demand is increasing for higher nanosilica purity, contamination is expected at the minimum level. Other than chemical synthesis, other processes such as precipitation, vaporization at high temperature, sol-gel process, high speed vertical rotating mill, and planetary ball mill are among the most commonly used methods to produce silica sand nanoparticles. The objective of this research is to design a technique of transforming natural Tronoh silica sand to silica sand nanoparticles by using a combination of low speed ball milling and heating processes. It is expected that the technique will be able to produce high purity silica sand nanoparticles of less than 100?nm consistently. Taguchi method provides a simple, efficient, and systematic approach to determine the optimum parameters [1]. Compared to the factorial method, instead of testing all possible combinations of parameters available, Taguchi method provides a more simplified way to set up the combination of experiment parameters. The parameters tested in this paper are ball to powder weight ratio (BPR), volume of milling jar, and milling speed. 2. Parameters Identification There are a lot of parameters used in ball milling process. However, the parameters that have been tested most for optimization are the rotation speed and milling time. This indicates that these two parameters play an important role in determining the effectiveness of the milling. As supported by Simoes, ball to powder weight ratio is recognized as one of the most influential parameters, alongside
