A influência do processo de terceirização de tecnologia da informação na utilização dos modelos de contratação de serviços: um estudo de casos múltiplos

The change in the economic world and the emergence of Internet as a tool for communication and integration among the markets have forced organizations to adopt a different structure, process-oriented with a focus on information management. Thus, information technology has gained prominence in the organizational context, increasing its complexity and range of services provided by this function. Moreover, outsourcing has become an important model for flexible corporate structure, helping organizations to achieve better results when carrying out their activities and processes and be more competitive. To make the IT outsourcing, it is necessary to follow certain steps that range from strategic assessment to the management of outsourced service. Such steps can influence the form of contracting services, varying the types of service providers and contractors. Thus, the study aimed to identify how this IT outsourcing process influences the use of models for contracting services. For this, a study was conducted in multiple cases study involving two companies in Rio Grande do Norte State, specifically the health sector. Data collection was carried out with the CIOs of the companies surveyed through semi-structured interviews. According to the results obtained, it was found that the outsourcing process more structured influences the use of a more advanced contracting model. However, there are features found in these steps carrying more clearly this influence, as the goals pursued by outsourcing, the criteria used in selecting the supplier, a contract negotiation, how to transition services and the use of methods management, but can vary depending on the level of maturity in the relationship of the companies examined. Moreover, it was found that the use of contracting model may also influence how it is developed the IT outsourcing process, requiring or not its more formalized and organization

Aspectos do gerenciamento de riscos de tecnologia da informação nas empresas: um estudo de caso múltiplos

The information technology - IT- benefits have been more perceived during the last decades. Both IT and business managers are dealing with subjects like governance, IT-Business alignment, information security and others on their top priorities. Talking about governance, specifically, managers are facing it with a technical approach, that gives emphasis on protection against invasions, antivirus systems, access controls and others technical issues. The IT risk management, commonly, is faced under this approach, that means, has its importance reduced and delegated to IT Departments. On the last two decades, a new IT risk management perspective raised, bringing an holistic view of IT risk to the organization. According to this new perspective, the strategies formulation process should take into account the IT risks. With the growing of IT dependence on most of organizations, the necessity of a better comprehension about the subject becomes more clear. This work shows a study in three public organizations of the Pernambuco State that investigates how those organizations manage their IT risks. Structured interviews were made with IT managers, and later, analyzed and compared with conceptual categories found in the literature. The results shows that the IT risks culture and IT governance are weakly understood and implemented on those organizations, where there are not such an IT risk methodology formally defined, neither executed. In addition, most of practices suggested in the literature were found, even without an alignment with an IT risks management process

Práticas de governança de tecnologia da informação: um estudo de caso em empresas de telecomunicações do Rio Grande do Norte

Fatores que influenciam a aceitação de práticas avançadas de gestão de segurança da informação: um estudo com gestores públicos estaduais no Brasil

This study examines the factors that influence public managers in the adoption of advanced practices related to Information Security Management. This research used, as the basis of assertions, Security Standard ISO 27001:2005 and theoretical model based on TAM (Technology Acceptance Model) from Venkatesh and Davis (2000). The method adopted was field research of national scope with participation of eighty public administrators from states of Brazil, all of them managers and planners of state governments. The approach was quantitative and research methods were descriptive statistics, factor analysis and multiple linear regression for data analysis. The survey results showed correlation between the constructs of the TAM model (ease of use, perceptions of value, attitude and intention to use) and agreement with the assertions made in accordance with ISO 27001, showing that these factors influence the managers in adoption of such practices. On the other independent variables of the model (organizational profile, demographic profile and managers behavior) no significant correlation was identified with the assertions of the same standard, witch means the need for expansion researches using such constructs. It is hoped that this study may contribute positively to the progress on discussions about Information Security Management, Adoption of Safety Standards and Technology Acceptance Model

O sistema de informação do tribunal colectivo dos géneros alimentícios: Estudo orgânico-funcional, produção e tramitação documental

Este trabalho é um estudo sobre o sistema de informação Tribunal Colectivo dos Géneros Alimentícios, como nasceu e como se desenvolveu, através do estudo orgânico-funcional, análise da produção e tramitação documental, desde a sua criação (1930) até à sua extinção (1976), através da aplicação do método de investigação quadripolar. Este método vai desenrolar-se mediante três actividades, cujo exercício se integra numa abordagem sistémica: a) Estudo da natureza da instituição a partir da análise dos seus fins, dos seus órgãos, das suas funções e da sua prática administrativa, tendo em conta tanto a evolução destes elementos ao longo do tempo como as relações que se estabelecem entre eles, através da análise de leis orgânicas e outros diplomas legais. b) Identificação e delimitação das séries documentais a partir da análise dos modos de produção documental, as características externas e internas destes tipos de documentos e as operações de conservação, descrição e organização arquivística. c) Apresentação do quadro de classificação: estrutura hierárquica e lógica que reflicta as funções deste sistema de informação. Pretende-se dar resposta às seguintes questões: 1- como classificar arquivisticamente a documentação acumulada no Arquivo Tribunal Colectivo dos Géneros Alimentícios? 2- Classificar arquivisticamente os processos de infracções/crimes do Tribunal de Recurso da Intendência-Geral da Segurança Pública e os processos de infracções/crimes até 1936 no sistema Tribunal Colectivo dos Géneros Alimentícios. 3- A produção e o circuito documental do Tribunal Colectivo dos Géneros Alimentícios são semelhantes à produção documental dos tribunais de jurisdição ordinária? 4- Quais a(s) especificidade(s) a nível processual e de tipologias documentais. ABSTRACT: This thesis is a study on the information system of the Tribunal Colectivo dos Géneros Alimentícios: how it started and how it was developed, and we do so proceding with the study of the organizational system, of the channeling of the proceedings and documents, since its creation (1930) until its ending (1976), using the quadripolar research method. This method will develop into three different steps, following a systemic approach and using the Quadripolar Method: a) A study of the nature of the institution supported by the analysis of its purposes, its organs, its functions and its administrative practices, bearing in mind the evolution of these elements throughout time and the connections that are established between them, with the support of some organic laws and other legal diplomas. b) Identification and caracterization of the document series; the method that it will be used will include an analysis of the process of document production, and also of both the internal and external characteristics of that type of documents and the archival conservation, description and organization. c) Demonstration of the classification board: hierarchic structure and the logic that is behind the institution of this documental base. This work intends to answer the following questions: 1. How to classify archival documentation accumulated in the Tribunal Colectivo dos Géneros Alimentícios? 2.

Fatores críticos de sucesso como antecedentes da aceitação de um sistema de informação em uma universidade federal

In recent decades the public sector comes under pressure in order to improve its performance. The use of Information Technology (IT) has been a tool increasingly used in reaching that goal. Thus, it has become an important issue in public organizations, particularly in institutions of higher education, determine which factors influence the acceptance and use of technology, impacting on the success of its implementation and the desired organizational results. The Technology Acceptance Model - TAM was used as the basis for this study and is based on the constructs perceived usefulness and perceived ease of use. However, when it comes to integrated management systems due to the complexity of its implementation,organizational factors were added to thus seek further explanation of the acceptance of such systems. Thus, added to the model five TAM constructs related to critical success factors in implementing ERP systems, they are: support of top management, communication, training, cooperation, and technological complexity (BUENO and SALMERON, 2008). Based on the foregoing, launches the following research problem: What factors influence the acceptance and use of SIE / module academic at the Federal University of Para, from the users' perception of teachers and technicians? The purpose of this study was to identify the influence of organizational factors, and behavioral antecedents of behavioral intention to use the SIE / module academic UFPA in the perspective of teachers and technical users. This is applied research, exploratory and descriptive, quantitative with the implementation of a survey, and data collection occurred through a structured questionnaire applied to a sample of 229 teachers and 30 technical and administrative staff. Data analysis was carried out through descriptive statistics and structural equation modeling with the technique of partial least squares (PLS). Effected primarily to assess the measurement model, which were verified reliability, convergent and discriminant validity for all indicators and constructs. Then the structural model was analyzed using the bootstrap resampling technique like. In assessing statistical significance, all hypotheses were supported. The coefficient of determination (R ²) was high or average in five of the six endogenous variables, so the model explains 47.3% of the variation in behavioral intention. It is noteworthy that among the antecedents of behavioral intention (BI) analyzed in this study, perceived usefulness is the variable that has a greater effect on behavioral intention, followed by ease of use (PEU) and attitude (AT). Among the organizational aspects (critical success factors) studied technological complexity (TC) and training (ERT) were those with greatest effect on behavioral intention to use, although these effects were lower than those produced by behavioral factors (originating from TAM). It is pointed out further that the support of senior management (TMS) showed, among all variables, the least effect on the intention to use (BI) and was followed by communications (COM) and cooperation (CO), which exert a low effect on behavioral intention (BI). Therefore, as other studies on the TAM constructs were adequate for the present research. Thus, the study contributed towards proving evidence that the Technology Acceptance Model can be applied to predict the acceptance of integrated management systems, even in public.

Certificação de qualidade versus qualidade da informação financeira: estudo para empresas portuguesas

O presente estudo tem como objetivo analisar se as empresas que têm implementado um Sistema de Gestão da Qualidade, certificadas segundo a norma da International Organization for Standardization (ISO) 9001, apresentam também uma boa qualidade da informação financeira. Neste sentido, pretende-se testar a expectável relação positiva entre a certificação de qualidade de uma empresa e a qualidade da sua informação financeira. Para isso, identificaram-se as empresas que possuem certificação do Sistema de Gestão de Qualidade, segundo a norma ISO 9001, enquanto a qualidade da informação financeira foi aferida utilizando como proxy os accruals discricionários estimados através do modelo Jones (1991). Utiliza-se um modelo logit para testar a relação pretendida, tendo como variável dependente a variável binária relativa à certificação de qualidade e como principal variável explicativa a qualidade da informação financeira. Com base nos resultados obtidos foi possível verificar a existência de uma relação positiva e estatisticamente significativa entre certificação de qualidade das empresas e a sua qualidade da informação financeira.

Crenças normativas e comportamentais e suas influências na intenção de adoção de um sistema de informação: um estudo na área de compras da UFPA

The study aims to identify the factors that influence the behavior intention to adopt an academic Information System (SIE), in an environment of mandatory use, applied in the procurement process at the Federal University of Pará (UFPA). For this, it was used a model of innovation adoption and technology acceptance (TAM), focused in attitudes and intentions regarding the behavior intention. The research was conducted a quantitative survey, through survey in a sample of 96 administrative staff of the researched institution. For data analysis, it was used structural equation modeling (SEM), using the partial least squares method (Partial Least Square PLS-PM). As to results, the constructs attitude and subjective norms were confirmed as strong predictors of behavioral intention in a pre-adoption stage. Despite the use of SIE is required, the perceived voluntariness also predicts the behavior intention. Regarding attitude, classical variables of TAM, like as ease of use and perceived usefulness, appear as the main influence of attitude towards the system. It is hoped that the results of this study may provide subsidies for more efficient management of the process of implementing systems and information technologies, particularly in public universities

Utilização de um ambiente virtual de aprendizagem: um estudo na perspectiva da prática docente

Advances related to information technology are visible and inherent to the management of contemporary organizations, regardless of industrial action. Synchronized with this dynamic, educational institutions are incorporating technological tools that assist its management and academic support to teachers in teaching and interaction with the students. Given that technological innovations are not always taken homogeneously and with the same degree of coverage, remain current and relevant studies on how these technologies are being used in academia. The objective of this research is to identify the usage profile of the functionality of a virtual learning environment related to teaching (undergraduate or postgraduate), demographic variables (age and gender) and institutional (time of admission and academic center of origin.) The methodology applied to the study is descriptive and quantitative. The research is characterized as census, covering all 2152 teachers of undergraduate and graduate students of the Federal University of Rio Grande do Norte, Brazil, who accessed the virtual classes of the Integrated Management of Academic Activities. The study findings revealed that there is a statistically significant difference regarding the use of these tools to teachers who work with undergraduate (49.3%) compared to graduate (6.6%). Regarding gender, women (40.1%) use the system more than men (38.5%). It was also observed that the younger teachers, aged 37 years, are the most active users (42.5%) of the Virtual Class with respect to their elders. For teachers with up to three years time of admission to the UFRN, the pattern of use is more advanced than those with more seniority, as well as the faculty of the Center for Science and Technology are the least likely to use the tools available in relation to other academic centers. It is hoped that with this study managers can direct actions to improve and expand the use of this environment by teachers

Aplicação de modelos de equações estruturais no estudo da eficácia de Sistemas de Gestão de Desempenho

Para fazer face às exigências da sociedade, as organizações têm a necessidade de desenvolver esforços de modo a aumentar a sua performance, através de práticas de gestão estratégica de recursos humanos. Nesta dissertação iremos aprofundar o estudo do modelo proposto por Marr (2009) para explicar a Cultura Orientada para o Desempenho e demonstrar os efeitos que a cultura tem nos Sistemas de Gestão de Desempenho, utilizando os Modelos de Equações Estruturais, através da análise de respostas obtidas sobre 325 colaboradores de empresas portuguesas do sector público e privado. Desta análise resultou a confirmação das quatro dimensões latentes de Cultura Organizacional propostas pelo autor, através da Análise Factorial Confirmatória, revelando também a sua importância e contributos diferenciados no Sistema de Gestão de Desempenho de uma organização. De um modo geral, verificou-se que as dimensões da Cultura contribuem de forma positiva para o aumento da eficácia de um Sistema de Gestão de Desempenho, alinhado com o modelo conceptual proposto e enfatizando a importância de se estudar as dimensões de Cultura e de Sistemas de Gestão de Desempenho de forma simultânea.

O projeto de arquitetura de espaços temporários com o uso de sistema construtivo remontável: um estudo exploratório

The purpose of this research is to study the portable or reassemblable architectures, which, different from conventional architecture (whose designs are of permanent buildings), corresponds to the designing of spaces with temporary purposes. The focus of the study is the architectural design of spaces that are produced from building systems that can to be moved to different places (process of assembly / disassembly / reassembly) in order to identify the types of spaces generated and the processes used in their design / projecting. The aim is to investigate relationships between the initial project conceived based on a Reassemblable Construction System (RCS) and its application in the architectural design of professionals and students in order to contribute to the understanding of the specificities of this type of design activity. To this end it was developed the exploratory research based on multimedia methods, which includes: documentary analysis, technical visits, interviews, surveys, academic exercise and documentation by images. Although the study is not conclusive, the results indicate significant differences between the point of view of the RCS´s designers and its users (architects and architecture students) since the users demonstrated to have some difficulty to access the features provided for the first group, in particular the students. It is also demonstrated that the use of RCSs seems to change the appreciation / hierarchization of the conditions of project design, since, unlike what happens in traditional architectural design, the designers who use them seem to be more concerned with constructive issues, especially the structural elements (support and covering), instead of functionality, aesthetics and even physical characteristics of the site
