A survey was conducted in Canada to assess the main determinants of information systems (IS) quality and success. The survey confirmed the notion that developer skills and contribution had the greatest impact on information systems quality, over process maturity and the application of the latest technology. The survey also discovered that user perception had a greater impact on IS success in comparison to IS quality. In an attempt to gain deeper insights into the state of IS quality and success in Canada, interviews were conducted with Canadian software developers. The interviews revealed that organization climate such as top management support, the social interactions and dynamics among project team members and the structural analysis of the industry are other factors which can influence the quality and success of the delivered software product. These insights if applied during the development and delivery of information systems can enhance the likelihood of producing high quality and successful software products and increase the competitiveness of these firms. <![CDATA[THE LITERATURE REVIEW OF TECHNOLOGY ADOPTION MODELS AND THEORIES FOR THE NOVELTY TECHNOLOGY]]> ABSTRACT This paper contributes to the existing literature by comprehensively reviewing the concepts, applications and development of technology adoption models and theories based on the literature review with the focus on potential application for the novelty technology of single platform E-payment. These included, but were not restricted to, the Theory of Diffusion of Innovations (DIT) (Rogers, 1995), the Theory of Reasonable Action (TRA) (Fishbein and Ajzen, 1975), Theory of Planned Behavior (TPB) (Ajzen, 1985, 1991), Decomposed Theory of Planned Behaviour, (Taylor and Todd, 1995), the Technology Acceptance Model (TAM) (Davis, Bogozzi and Warshaw, 1989, Technology Acceptance Model 2 (TAM2) Venkatesh and Davis (2000) and Technology Acceptance Model 3 (TAM3) Venkatesh and Bala (2008). These reviews will shed some light and potential applications for technology applications for future researchers to conceptualize, distinguish and comprehend the underlying technology models and theories that may affect the previous, current and future application of technology adoption. <![CDATA[THE ADOPTION OF BIG DATA SERVICES BY MANUFACTURING FIRMS: AN EMPIRICAL INVESTIGATION IN INDIA]]> ABSTRACT Although some leading companies are actively adopting Big data services (BDS) to strengthen market competition , many manufacturing firms are still in the early stage of the adoption curve due to lack of understanding of and experience with BDS. Hence, it is interesting and timely to understand issues relevant to BDS adoption. The empirical investigation reveals that a firm’s intention to adopt BDS can be positively affected by the quality and benefits of BDS. Surprisingly, a firm’s absorptive capacity in utilizing big data and risks and costs associated with implementation and maintenance does not impact the adoption intention of BDS. <![CDATA[INFORMATION TECHNOLOGY GOVERNANCE IN PUBLIC ORGANIZATIONS: IDENTIFYING MECHANISMS THAT MEET ITS GOALS WHILE RESPECTING PRINCIPLES]]> ABSTRACT The purpose of this article is to identify and validate a list of mechanisms that can meet the objectives and principles of IT Governance (ITG) in public organizations. These mechanisms can be useful to public organizations when implementing their ITG model. ITG mechanisms are a key part of an ITG model because high-level definitions (principles and objectives) are operationalized through them. This exploratory and descriptive cross-sectional research used qualitative and quantitative data. Data were collected in a literature review, structured interviews with ITG professionals and a survey with IT and Business Managers who belong to a network of managers, which is one of the main instances to discuss the ITG model. The results are a preliminary list of mechanisms identified through qualitative data and a final list of mechanisms validated through quantitative data. The focus is on public organizations because the necessity of an ITG model as a better means to govern the electronic services adoption in order to increase the public value to society. <![CDATA[SUSTAINABILITY IN INFORMATION TECHNOLOGY: AN ANALYSIS OF THE ASPECTS CONSIDERED IN THE MODEL COBIT]]> ABSTRACT Parallel to the development of technology in its different fronts and particularly about the various applications of Information Technology (IT), another trend that has been consolidated in organizations is the search for sustainability. There are initiatives such as Green IT, Sustainable IT, and Green software that combine these two elements (IT and sustainability). In this context, this study aims to identify the presence of sustainability aspects in the COBIT (Control Objectives for Information and Related Technologies) model of IT management. Thus, this article seeks to verify if and how versions 4.1 and 5 of the COBIT model-which guide IT managers in the alignment of technical activities with the organization's strategy-are related to sustainability, through the use of sustainability indicators defined by the Global Reporting Initiative (GRI) as a representative proxy of sustainability aspects necessary for the user organization of the model. This exploratory research makes use of documental research and presents the following main results: (1) partial alignment of the COBIT model with the generic categories of the GRI, especially the governance category; and (2) it highlights the small relation of this model with broader environmental and social aspects in the same way that it presents relationship limitations with economic aspects evaluated by the GRI. <![CDATA[REGULATION MISUNDERSTANDING: CONVERGENCE COMPLEXITY PROVIDING FAILURES IN TELECOMMUNICATION SERVICES COSTS]]> ABSTRACT This manuscript discusses a theoretical competitive scenario for telecommunications services, in particular voice over Internet protocol (VoIP), and finds that the economic benefits of the current technological convergence are based on three main factors: technological advances and updates; regulation failures related to technological complexity; and consumer inability to exploit the benefits of convergence. This study begins by giving the background to voice communication in the telecommunications sector and the misunderstanding of the competitive boundaries between technologies, service providers, and usage applications generated in an unregulated sector. Second, the kinds of regulation that organizes the development and pricing of integrated or bundled services are briefly discussed and presented. Third, theoretical analysis of the competitive environment is interpreted in terms of the three factors: technological advances, regulation failure, and consumer knowledge of convergence. Results derived from these factors are presented in the context of VoIP services. Finally, the work concludes by outlining the implications for regulatory reform and the impact on competitive behavior, and describes possibilities for the future management of the technology sector.
