    ABSTRACT: This paper analyzes maturity levels in sectorial technological processes using Data Mining (DM). As a methodological tool for data collection it was used COBIT 4.1 model with its 34 processes in 4 different domains. This model was used in the analysis of a sample of Brazilian companies located in southern Brazil. Clustering techniques, feature selection strategies and association rules were used. In particular, a good performance was obtained using the EM clustering algorithm and the Apriori association rule generator, both implemented in Weka software. The data mining approach provides an improvement in the risk analysis, security and governance in the companies.

    ABSTRACT: The organizational images allow visualizing the business context in which organizations are embedded, and define behavioral models that respond to their organizational culture. This work begins with the approach of Morgan (1986) and uses 35 questions to identify metaphors in a sample of companies in the state of Rio Grande do Sul. Quantitative analysis was performed by data mining techniques. The techniques identified images that are present in the sample. Analyzes are importance for the management of culture and business behavior, due to the identification of images may achieve organizational objectives.

    ABSTRACT: The information is a strategic resource of first order for organizations, so it is essential to have methodologies and tools that allow them to properly manage information and extract knowledge from it. Organizations also need knowledge generation strategies using unstructured textual information from different sources and in different languages. This paper presents two bio-inspired approaches to clustering multilingual document collections in a particular field (economics and business). This problem is quite significant and necessary to organize the huge volume of information managed within organisations in a global context characterised by the intensive use of Information and Communication Technologies. The proposed clustering algorithms take inspiration from the behaviour of real ant colonies and can be applied to identify groups of related multilingual documents in the field of economics and business. In order to obtain a language independent vector representation, several linguistic resources and tools are used. The performance of the algorithms is analysed using a corpus of 250 documents in Spanish and English from different functional areas of the enterprise, and experimental results are presented. The results demonstrate the usefulness and effectiveness of the algorithms as clustering technique.

    ABSTRACT: Different theories of organization and management are based on implicit images or metaphors. Nevertheless, a quantitative approach is needed to minimize human subjectivity or bias on metaphors studies. Hence, this paper analyzed the presence of metaphors and clustered them using fuzzy data mining techniques in a sample of 61 Brazilian companies that operate in the state of Rio Grande do Sul. For this purpose the results of a questionnaire answered by 198 employees of companies in the sample were analyzed by R free software. The results show that it is difficult to find a clear image in most organizations. In most cases characteristics of different images or metaphors are observed, so soft computing techniques are particularly appropriate for this type of analysis. However, according to these results, it is noted that the most present image in the organizations studied is that of “organisms” and the least present image is that of a “political system” and of an “instrument of domination”

    ABSTRACT: This paper analyzed, under the Resource-Based View (RBV) perspective, the internal Information Technology (IT) resources as providers for competitive advantage. The main analysis of this historical longitudinal study investigated 17 strategic attributes through a qualitative exploratory approach. Each strategic attribute was identified, characterized and defined according to the corresponding RBV authors, before being used in the analysis. This multiple case study considered the competitive dynamics in two metal-mechanic leading and highly competitive organizations in terms of technological innovation. The study consists of interviews with 16 senior executives (12 CEOs and four CIOs) whose narrative made possible the reconstruction of twenty years of competitive history, considering relevant economic events or critical phases identified during each studied period. After the reconstruction of the competitive history, the identification of resources, and the critical economic events the senior executives were encouraged to give their opinion about the strategic potential of the identified IT resources. Understanding IT intervention was important to study the way matching to the adopted instrument the IT resources support competitiveness according to the RBV perspective. Content analysis, following Bardin's approach, was useful to the unveiling of meanings from different speeches based on inference or deduction and, simultaneously, following specific criteria to generate proper data for the theme structures. The IT resources did not contribute strategically dissociated from the other resources during the critical economic events faced by the two organizations. The two organizations recognized the strategic potential of using integrated resources for the development of new strategies and the maintenance of the existing ones. Among the results, the study revealed the different IT strategic attributes and their interaction with the critical events at the studied organizations. The strategic attributes were associated to some of the identified resources, such as Product Configurator (PC), Commercial Module (CM) and Virtual Manufacture (VM).

    ABSTRACT: This paper develops the strategic alignment of organizational behavior through the organizations´ image, prioritization and information security practices. To this end, information security is studied based on the business requirements of confidentiality, integrity and availability by applying a tool which integrates the strategic, tactical and operational vision through the following framework: Balanced Scorecard - BSC (strategic) x Control Objectives for Information and Related Technology - COBIT (tactical) x International Organization for Standardization - ISO/International Electro Technical Commission - IEC27002 (operational). Another image instrument of the organization is applied in parallel with this analysis to identify and analyze performance involving profiles related to mechanistic, psychic prisons, political systems, instruments of domination, organisms, cybernetics, flux and transformation (MORGAN, 1996). Finally, a model of strategic prioritization, based on compensatory fuzzy logic (ESPIN and VANTI, 2005), is applied. The method was applied to an industrial company located in southern Brazil. The results with the application show two organizational images: "organism" and "flux and transformation ". The strategic priorities indicated a significant search for new business services and international markets. Regarding protection of information, security found the gap between "minimum" and "Reasonable" and in domain 8 (HR) of standard ISO/IEC27002, considered 71% protection as "inappropriate" and "minimal" in the IT Governance context.

    ABSTRACT: The present work develops the analysis of two strategic maps. One is based on the principles of Compensatory Fuzzy Logic (CFL) and the other studies Organizational Culture. The research is applied with a quali-quantitative approach and it studies the case of a software development company with the use of a technical procedure and a documentary base with the application of interviews and questionnaires. It concludes that the strategic maps based on and Organizational Culture are robust methodologies that identify and prioritize strategic variables. There is also an interrelationship amongst them in their consideration of important behavioral aspects. With this it was possible to analyze strategic aspects of the companies in a more complex and realistic way.

    ABSTRACT: The aim of the present research is performing an informal analysis for internal audit involving the application of complex information system based on fuzzy logic. The same has been applied in internal audit involving the integration of the accounting field into the information systems field. The technological advancements can provide improvements to the work performed by the internal audit. Thus we aim to find, in the complex information systems, priorities for the work of internal audit of a high importance Private Institution of Higher Education. The applied method is quali-quantitative, as from the definition of strategic linguistic variables it was possible to transform them into quantitative with the matrix intersection. By means of a case study, where data were collected via interview with the Administrative Pro-Rector, who takes part at the elaboration of the strategic planning of the institution, it was possible to infer analysis concerning points which must be prioritized at the internal audit work. We emphasize that the priorities were identified when processed in a system (of academic use). From the study we can conclude that, starting from these information systems, audit can identify priorities on its work program. Along with plans and strategic objectives of the enterprise, the internal auditor can define operational procedures to work in favor of the attainment of the objectives of the organization.

    ABSTRACT: The Brazilian Industry's profile has suffered several changes along the years upon going through many economic stagnation processes to an actual growth process. Brazil has opened its borders for the international market and consequently has increased competitiveness, productivity and the innovation capacity. Through all these changes, the Brazilian companies are getting a more flexible management, and in terms of strategic planning, the companies need to get more flexible tools to help in the decision making process. In this work, the importance of the definition of objectives and strategic lagging and leading indicators in the chain import and export process in the light of strategic planning through the use of Fuzzy Logic System is presented. The referring system is mathematically detailed in Espin and Vanti (2005) and Espin; Becker and Vanti (2005). The system has been applied in a company active in the import and export segment, which is located in Rio Grande do Sul State, Brazil for 48 years. Therefore, the question is: What's the order of importance of lagging and leading indicators and objectives in the chains import and export process.

    ABSTRACT: Resumen El exceso de información y la dispersión de los datos en el ambiente empresarial se han constituido en importantes barreras a ser superadas por los gestores en la actualidad. El análisis eficaz de datos e informaciones internas y externas a la empresa se constituye en un medio para la obtención y/o sustentación de una ventaja competitiva. De esta forma, el propósito de este artículo es presentar, a través de una perspectiva teórica, algunos elementos que puedan integrar una configuración informacional para apoyar la tomada de decisiones estratégicas en la empresa. En este contexto, la gestión de la cadena de valor es presentada como base para la ventaja competitiva y los elementos de gestión y Tecnología de la Información (TI) tratados en este artículo son ubicados en un flujo de decisiones estratégicas con el fin de proveer un mejor entendimiento de la infraestructura tecnológica disponible en el mercado. Palabras claves: configuración informacional, decisiones estratégicas, cadena de valor Área Temática: Convergencia multidisciplinar en los procesos informativos 1 Introducción La gestión organizacional, en especial el proceso de tomada de decisiones, todavía carece de flexibilidad, agilidad y eficacia a través de la obtención y tratamiento de las informaciones de los ambientes externo e interno de la empresa en función de las exigencias del mercado. La utilización de estas informaciones en un análisis estratégico es imprescindible para el alcance y sustentación de una ventaja competitiva empresarial. Sin embargo, esa ventaja ocurre debido al carácter idiosincrásico por el cual las empresas absorben y analizan las informaciones cualitativa y cuantitativamente dispuestas en el ambiente en general.
