Em princípio, uma boa avaliação pode ser uma garantia de que a contratação será bem sucedida. Este trabalho verificou se as empresas adotam procedimentos diferenciados quando selecionam fornecedores de serviços de Tecnologia da informação (TI). Procurou-se identificar os procedimentos de avaliação e os critérios de seleção utilizados para a escolha de empresas fornecedoras de serviços de TI. Os resultados mostraram que, em função de peculiaridades das atividades de TI, o processo de seleção de fornecedores incorpora características específicas, sem contudo apresentar a sofisticação inicialmente esperada.

Based on thisstatement, the current paper is focused on the understanding the relationship between technological innovation and competitivity observed in the electromedical equipments industry and on the identification of major factors that may influence that relationship. Two exploratory researches were conducted using qualitative methodologies: one was based on the Grounded Theory and the other using Content Analysis. The first research brought evidences of the importance of technological innovation on the production chain to achieve competitivity. The second research identified the following factors that influence that relationship: strategies employed to innovate; external environmental conditions that favor innovation; favorable stimuli of innovation; and internal conditions that favor innovation. These factors converge to obtain desirable benefits from innovation that lead to competitive advantages. The study confirmed the hypothesis that manufacturers use technologicalinnovation to get competitive advantages.

Um dos conflitos se relaciona com a inovação, pois as organizações necessitam inovar para obter resultados no longo prazo, porém mantendo o controle racional dos recursos para sobreviver no curto prazo. Este estudo tem o objetivo de identificar se esse conflito é presente e identificar outras características do SCG em três empresas brasileiras classificadas como inovadoras na listagem de empresas que compõem o Índice Brasil de Inovação desenvolvido pela UNICAMP/UNIEMP/FAPESP em 2007. Fundamentado no referencial teórico Uso Diagnóstico e Uso Interativo do SCG proposto por , estudaram-se três empresas por meio da realização de entrevista presencial com profissionais da área de controladoria, com posterior análise de conteúdo. Os resultados indicaram que o conflito entre inovação e controle não está presente nessas organizações, o que pode ser explicado pelo fato da inovação ser um valor permanente dessas organizações. O resultado também mostrou que estas empresas utilizam os artefatos de controle gerencial classificados como tradicionais e que estes não inibem a inovação, sendo, ao contrario, importantes para estimular a inovação. A limitação da pesquisa é que as observações se restringiram à entrevista e ao pequeno número de empresas, o que impede a generalização dos resultados, mas mesmo assim o estudo contribui no sentido de evidenciar aspectos relevantes da prática e sugere novas pesquisas com maior número de empresas.

It has researched into an Electronic Patient Record system in an Emergency Ward and a Teaching Support System by Web in a Medicine College. Two pieces of field qualitative research have been carried out through adopting the technique of exploratory nature, conducted by interviewsin-depth with the main managers and key-users which influence the adoption of the innovation. The research outcome indicates (among other aspects), that the channels used for spreading innovation, for spreading the performance of change providers agents and the preparation for change are aspects that definitely determine the adoption of information systems in the health area. e Wetherbe (2006), um Sistema de Informação é um sistema capaz de coletar, processar, armazenar, analisar e disseminar informações para atender um propósito específico. Como qualquer sistema, um SI inclui entradas (dados e instruções) e saídas (relatórios e cálculos) (Nickerson, 2001) e também engloba pessoas, procedimentos e facilidades físicas e opera em um determinado ambiente (Turban, Rainer Jr & Potter, 2003).

Dada a natureza do procedimento de coleta, foi adotado o método de pesquisa quantitativa e utilizouse a técnica multi-variada da Análise Fatorial, com a finalidade de identificar e analisar as informações subjacentes às variáveis estudadas. Os resultados obtidos apresentaram evidências de que o ensino de pósgraduação esperado pelo aluno que o procura não é aquele voltado ao imediatismo e ao tecnicismo, mas sim um tipo de ensino mais holístico com amplos horizontes de análise. Neste artigo, a partir da percepção do público-alvo, ficou evidenciada a necessidade de implementação de cursos de pós-graduação com uma visão estratégica voltada para a modernidade.

The study presents two theoretical models based on Cognitive Psychology and Neuroeconomics, that are used to create a new theoretical model to analyze the decision making process. The article presents the results of a quantitative research, using Structural Equation Modeling (SEM) with a dataset obtained through questionnaires sent to functional managers from a Brazilian innovative organization charged with decisions on budget targets. The main contribution of this study is that it analyzes the decisions regarding the establishment of budgetary target levels, a more complex decision than the decision between two or more possible alternatives, as proposed in the studies using the Prospect Theory. In estimating the appropriate target level, managers must take into account the information about the internal and external environment and the consequences of choosing one over another level; the consequences are not clear since they do not know all the other possible alternatives. This study confirms the model proposed which takes into account some variables considered to be in the black box of the economic theory decision models, such as selective attention, memory, reasoning, expertise and intuition.

Managers of areas such as Accounting, Finance and, specially, Information Systems (IS) and Information Technology (IT) need support and tools for ERP selection. This paper presents a study conducted to classify assessment criteria which can then be used in analysis involving a Decision Support System (DSS), which will allow the assessment of the impacts of the organization changes related to the implantation of the selected system. The classification was obtained using Delphi, applied to experts in the selection and implantation of ERP. Results were satisfactory after two rounds, which demonstrated its plausibility to determine the importance of the assessment criteria, among which the following were highlighted: functionality; cross modular integration; information (reference) about supplier; ‘implementability’ and flexibility. A escolha de ...

Organizational Memory Information Systems (OMIS) emerge as an enhancer of the OM, providing effective support and resources for the organization, assisting in decision making, in the solution of problems, as well as in quality and development of products and services. This article is an analysis of some OMIS selected from a literature review about its features and functionality in order to understand how these information systems are seen by the organizations. With this research, we realized that the relationship between OM and IS is still inexpressive, even with the existence of some cases of success in the use of OMIS in the literature. The literature reveals that an individuals' knowledge is not integrated in information systems management process in most organizations; much of this knowledge is generated in the organization retained in an individual himself/herself. It is easy to see that there is a need for strategies and mechanisms in the organization to stimulate and provide better knowledge sharing between individuals which, when associated to IS, allows greater control and effective use of Organizational Memory.
