  • Antecedents to website satisfaction, loyalty, and word-of-mouth Articles

    Coker, Brent

    Resumo em Inglês:

    Satisfaction, 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.
  • The evaluation and improvement of it governance Articles

    Lorences, Patricia Pérez; Ávila, Lourdes Francisca García

    Resumo em Inglês:

    The present article aims to propose a general procedure to evaluate and improve the Information Technology (IT) Governance in an organization, considering the Business - IT alignment and risk management. The procedure integrates management tools such as business processes management, risk management, strategic alignment and the balanced scorecard. Additionally, to assess the IT Governance level we proposed an indicator based on the process maturity. The concepts and ideas presented here had been applied in four case studies, verifying their implementation feasibility. The results indicate a low level of IT governance and the existence of several problems primarily in the Plan and Organize and Monitor and Evaluate domains.
  • Using university ranking systems to predict usability of university websites Articles

    Hasan, Layla

    Resumo em Inglês:

    This research investigated whether a university ranking system called Eduroute could provide useful information regarding the usability of universities' websites. A comparison was conducted between the results obtained by Eduroute regarding the ranking of the top three universities in Jordan, and the results obtained by the heuristic evaluation method regarding the usability of the top three universities' websites. Before employing the heuristic evaluation method, two steps were taken: Investigating the most frequently visited pages on a university's website from the viewpoint of 237 students, and developing a set of comprehensive heuristics specific to educational websites. Then, five heuristic evaluators were selected and asked to visit all the pages determined by the 237 students using the developed heuristics while evaluating each website. The results proved that the ranking of the three universities at Eduroute was an indicator regarding the overall usability of the sites; the first ranked university at Eduroute had the lowest number of usability problems identified by the evaluators, while the least ranked university had the largest number of usability problems. The heuristic evaluators also identified fourteen common usability problems on the three tested websites related to navigation, design, content, and ease of use and communication.
  • Information architecture analysis using business intelligence tools based on the information needs of executives Articles

    Affeldt, Fabrício Sobrosa; Silva Junior, Sady Darcy da

    Resumo em Inglês:

    Devising an information architecture system that enables an organization to centralize information regarding its operational, managerial and strategic performance is one of the challenges currently facing information technology. The present study aimed to analyze an information architecture system developed using Business Intelligence (BI) technology. The analysis was performed based on a questionnaire enquiring as to whether the information needs of executives were met during the process. A theoretical framework was applied consisting of information architecture and BI technology, using a case study methodology. Results indicated that the transaction processing systems studied did not meet the information needs of company executives. Information architecture using data warehousing, online analytical processing (OLAP) tools and data mining may provide a more agile means of meeting these needs. However, some items must be included and others modified, in addition to improving the culture of information use by company executives.
  • The impact of it governance on it projects -the case of the ghana rural bank computerization and inter-connectivity project Articles

    Allassani, William

    Resumo em Inglês:

    This 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 'why 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.
  • Legitimation implications in the process of implementing an erp system in a holding company Articles

    Theiss, Viviane; Krespi, Nayane Thais; Lavarda, Carlos Eduardo Facin

    Resumo em Inglês:

    The objective of the study is to evaluate the legitimation of the process of implementing an ERP system in a holding company. The conceptual model is based on the New Institutional Sociology, with the evaluation of the legitimation of a new information system in the organization studied. The data collection procedures employed interviews, questionnaires, as well as the analysis of documents provided by the company. As the system is already part of the company's processes and the employees have already accepted the changes, it provides evidence of legitimation of the ERP system in the business.
  • Do information and communication technology access and innovation increase outsourcing in small and medium enterprises? Articles

    Alderete, María Verónica

    Resumo em Inglês:

    In this paper we present an econometric model to determine whether an SME (Small and Medium Sized Enterprise)'s 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.
  • A critical review of knowledge management in software process reference models Articles

    Galvis-Lista, Ernesto; Sánchez-Torres, Jenny Marcela

    Resumo em Inglês:

    Knowledge 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.
  • Achieving maturity (and measuring performance) through model-based process improvement Articles

    Cestari, Jose Marcelo Almeida Prado; Valle, Arthur Maria do; Lima, Edson Pinheiro de; Santos, Eduardo Alves Portela

    Resumo em Inglês:

    This paper presents the approach adopted by a software development unit in order to achieve the maturity level 3 of CMMI-DEV and therefore obtaining better performance. Through historical research and secondary data analysis of the organization, the paper intends to answer the following research question: "Could the adoption of maturity/best practices models bring better performance results to small and medium organizations?" Data and analysis conducted show that, besides the creation of indicator's based management, there are some quantitative performance improvements in indicators such as: Schedule Deviation Rate, Effort Deviation Rate, Percent Late Delivery, Productivity Deviation and Internal Rework Rate
  • Measurement process of software development projects for supporting strategic business objectives in software developing companies Articles

    Pedroso, Sandra Laís; Oliveira, Leonardo Rocha de

    Resumo em Inglês:

    Software developing companies work in a competitive market and are often challenged to make business decisions with impact on competitiveness. Models accessing maturity for software development processes quality, such as CMMI and MPS-BR, comprise process measurements systems (PMS). However, these models are not necessarily suitable to support business decisions, neither to achieve strategic goals. The objective of this work is to analyze how the PMS of software development projects could support business strategies for software developing companies. Results taken from this work show that PMS results from maturity models for software processes can be suited to help evaluating operating capabilities and supporting strategic business decisions.
  • Information technology as a technical resource for the memories: memories of unati-marília in the virtual environment Articles

    Paiva, Simone Borges; Del-Masso, Maria Candida Soares

    Resumo em Inglês:

    UNATI (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.

    Aranda, Yadira Robles; Sotolongo, Anthony R.

    Resumo em Espanhol:

    En 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.

    Resumo em Inglês:

    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.
