Do information and communication technology access and innovation increase outsourcing in small and medium enterprises?
Get PDFIn this paper we present an econometric model to determine whether an SME (Small and Medium Sized Enterprise)\u27s probability of outsourcing depends on their levels of innovation and information and communication technology use. The predictions of the econometric model are tested by means of a LOGIT model using a cross section sample of an Argentinean SME for the year 2006. The model predicts that the level of innovation of an SME will significantly influence its probability of outsourcing. Besides, it stresses the negative incidence of the information and communication technologies (ICT) access on the outsourcing decision
Antecedents to website satisfaction, loyalty, and word-of-mouth
Get PDFSatisfaction, loyalty, and likelihood of referral are regarded by marketers and the Big Three diagnostics leading to retail profitability. However, as yet no-one has developed a model to capture all three of these constructs in the context of the internet. Moreover, although several attempts have been made to develop models to measure quality of website experience, no-one has sought to develop an instrument short enough to be of practical use as a quick customer satisfaction feedback form. In this research we sought to fill this void by developing and psychometrically testing a parsimonious model to capture the Big Three diagnostics, brief enough to be used in a commercial environment as a modal popup feedback form
Metamodel of the it governance framework COBIT
Get PDFEste artigo aborda a geração e análise do metamodelo ontológico do framework COBIT de Governança de TI. Os metamodelos ontológicos representam, a partir de um nível superior de abstração, os componentes conceituais e a rica estrutura lógica e semântica dos relacionamentos dos frameworks de melhores práticas de TI, bem como possibilitam a análise, adaptação, comparação, integração e fusão de frameworks . Utilizou-se, na criação do metamodelo, a metodologia MetaFrame, fundamentada na disciplina de metamodelagem conceitual e na metodologia Entidade/Relacionamento estendida, que possui um processo iterativo de construção dos componentes do metamodelo, utilizando técnicas de modelagem e documentação de sistemas de informação, fazendo a verificação dos resultados baseada em critérios de qualidade. No metamodelo do COBIT 4.1 obtido, o tipo entidade central é o Processo de TI, o tipo entidade Domínio de TI representa os quatro domínios que agrupam um ou mais processos de TI do COBIT 4.1 que, por sua vez, estão divididos em uma ou mais Atividades, que são realizadas por um Papel ou mais, que são consultados, informados, prestam contas, ou se responsabilizam por cada Atividade. Como aplicação, o metamodelo do COBIT 4.1 poderá sugerir a adaptação ou implementação de um novo processo dentro do framework ou mesmo contribuir para a integração de frameworks , quando, após os processos de análise e comparação, encontram-se os pontos de conexão entre os componentes e as estruturas lógicas dos seus relacionamentos.This paper addresses the generation and analysis of the COBIT 4.1 ontological metamodel of IT Governance framework. The ontological metamodels represent the logical structures and fundamental semantics of framework models and constitute adequate tools for the analysis, adaptation, comparison and integration of IT best practice frameworks. The MetaFrame methodology used for the construction of the COBIT metamodel is based on the discipline of conceptual metamodeling and on the extended Entity/Relationship methodology. It has an iterative process of construction of the metamodel’s components, using techniques of modeling and documentation of information systems. In the COBIT 4.1metamodel, the central entity type is the IT Process. The entity type of IT Domain represents the four domains that group one or more IT processes of the COBIT 4.1. In turn, these domains are divided into one or more Activities that are carried through by one or more Roles which are consulted, informed, accounted for or liable for each Activity. The COBIT 4.1 metamodel may suggest adaptation or implementation of a new process within the framework or even contribute to the integration of frameworks, when, after the processes of analysis and comparison, there are connection points between the components and the logical structures of its relationships
Business professionals\u27 perceptions related to the influence of information technology in individual work
No full textAccording to the literature, much has been said about the impact of Information Technology on organizations, but little about its impact on the individual. This study aims to identify Information Technology benefits in individual work, choosing as a proxy some "latu sensu" post-graduation students, from a federal university in the south of Brazil. For data collection, a questionnaire based on the studies by Torkzadeh and Doll (1999) and Pereira (2003) was prepared. Torkzadeh and Doll dealt with the process of working; Pereira, with the four phases of the decision-making process. The final instrument, after being validated and tested, amounted to 21 questions to detect the potential benefits of Information Technology. The results demonstrated that users are satisfied, by pointing an average of 2.69 on a scale of "1" (little satisfied) to "5" (very much satisfied). The framework, work process, got an overall average [2.82]. Managerial control [3.10] and productivity [3.06] had the highest ratings; innovation [2.34], the lowest one. With technologies fully implemented, greater satisfaction was observed for all constructs of the survey, with statistically significant differences. Such differences were also proven in the Information Technology solutions that use Enterprise Resource Planning technology, the best-evaluated one. When comparing age, it was found that younger users were more satisfied with the benefits of technology. Concerning the number of employees, small business users were less satisfied with Information Technology
A critical review of knowledge management in software process reference models
Get PDFKnowledge Management (KM) is a critical subject for software development organizations. For this reason, the purpose of this article is to provide a critical review on the way that KM is included in several models of reference of software process (SPRM). For this, five SPRM used in the Latin American countries were selected. Then, an analysis of each process of the SPRM was performed in order to identify features related to the KM. Finally, the KM aspects were mapped in relation to the KM schools (Earl) and the KM capacities (Gold et al). The main contribution of the paper is to show some breaches in SPRM content in relation to KM schools and capabilities
Information technology as a technical resource for the memories: memories of unati-marilia in the virtual environment
No full textUNATI (Open University of the Third Age), UNESP, Marília campus, has offered subsidies for the development of this work aimed at researching the existing relationships between information mediation processes and technological devices, especially computers, assuming that reading practices and textual construction in on-line environments could help the "third age" population to have access to these devices, thus promoting digital inclusion in this group. Mediation was presented as an interventionist action that, by introducing an intermediate element in the learning process, causes a rupture in the ways of living and personal digital inclusion processes hitherto experienced. In the context of a workshop, we found out that there is a physical relationship between subjects and technological supports and such a contact proved to be necessary, considering that handling a computer required knowledge of procedures, thus furthering a logic of use. It turned out to be necessary to develop actions that would enable the handling of a computer so as to bring about acceptance of these supports. Accordingly, activities were developed so as to articulate reminiscent processes, memories of older adults, the writing down of such memories and the creation of a blog to bring enhanced visibility to the content produced by older people. Such actions have shown that remembering, writing down and posting can reshape not only social relations but somehow significantly promote digital inclusion among older adults
The influence of shared mental models between the CIO and the Top Management Team on the strategic alignment of Information Systems: a comparison between brazilian and US companies
Get PDFThe gap in the understanding between the chief information officer (CIO) and the management team (TMT) has been cited as a contributing factor to their often troubled relationship. The objective of this study is to examine the development of shared mental models (SMMs) between the CIO and TMT about the role of information systems in the organization. An SMM is conceptualized as a multidimensional construct spanning the dimensions of shared language and shared understanding. The study posits that knowledge exchange mechanisms and relational similarity between the CIO and TMT are key antecedents to the development of SMMs. SMMs between the CIO and TMT are expected to guide the strategic orientation of the organization and may influence strategic alignment and organizational outcomes. The model was tested via a field survey of CIO – TMT pairs using structural equation modeling. Results show that relational similarity and formal mechanisms of knowledge exchange (e.g., formal CIO membership in the TMT, CIO hierarchical level, and formal educational mechanisms by the CIO) are important to the development of SMMs. Contrary to expectations, informal social mechanisms of knowledge exchange and physical proximity were not significantly related to SMMs.The gap in the understanding between the chief information officer (CIO) and the management team (TMT) has been cited as a contributing factor to their often troubled relationship.

Get PDFEn la presente investigación se analizaron las técnicas de minería de datos de árboles de decisión y de reglas de inducción para integrar varios de sus algoritmos al sistema gestor de base de datos (SGBD) PostgreSQL, buscando suplir las deficiencias de las herramientas libres existentes. También se propuso un mecanismo para optimizar el rendimiento de los algoritmos implementados con el objetivo de aprovechar las ventajas de PostgreSQL y se comprobó, mediante un experimento, que al utilizar los algoritmos integrados al gestor, los tiempos de respuestas y los resultados obtenidos son superiores.In this research, data mining and decision tree techniques were analyzed as well as the induction of rules to integrate their many algorithms into the database managing system (DBMS), PostgreSQL, due to the defficiencies of the free use tools avaialable. A mechanism to optimize the performance of the implemented algorithms was proposed with the purpose of taking advantage of the PostgreSQL. By means of an experiment, it was proven that the time response and results obtained are improved when the algorithms are integrated into the managing system
The impact of it governance on it projects -the case of the ghana rural bank computerization and inter-connectivity project
Get PDFThis research seeks to analyse the root causes of the massive failures of IT Projects especially in government establishments. This study shows that the successful implementation of IT projects does not lie only Project in Management principles. It answers the question \u27why are IT projects failing despite the application of tried and tested Project Management principles ? The paper also concludes that Project Management principles per se do not guarantee the successful implementation of IT projects, but have to be brought within the principle of IT Governance. Conclusions are drawn from the Ghana Rural Bank Computerization and Inter-connectivity Project, an activity under the Millennium Challenge Account of the Millennium Development Authority to show that IT Governance needs to be inculcated into IT Projects to make its implementation successful
