Estruturas de gestão de informações para inteligência de negócio nas organizações e o impacto individual nas atividades / Management structures of information for business intelligence in organizations and the individual impact on activities

Sergio Augusto Orfão Pinto 06 September 2012 (has links)
Os sistemas de informação para inteligência de negócio (conhecidos também como BI - Business Intelligence) têm o propósito de coletar, estruturar, preparar e disponibilizar informações referentes aos processos internos e ao ambiente externo das organizações. O uso dessas informações visa suportar o processo de tomada de decisão bem como administração e inovação dos próprios processos de negócio das organizações. Dessa forma, essa classe de sistemas de informações (BI) tem o potencial de melhorar o desempenho individual e organizacional, sendo uma fonte de vantagem competitiva para as organizações. A abordagem de sistemas para BI não pode ser considerada somente como uma sequência de projetos isolados para disponibilização de informações. A gestão das demandas de informações necessárias para o negócio requer um esforço permanente para manter a função de BI alinhada com as necessidades da organização, através de processos que garantam a disponibilidade, o uso de informações e análises compartilhadas com base nos mesmos conceitos, documentação e organização das informações, assim como o suporte e treinamento técnico e funcional nos sistemas existentes. Nesse contexto, surgiu a proposta dos centros de competências de informações para BI, como uma estrutura de suporte para todas as áreas de negócio, sendo o elemento de ligação entre a área de tecnologia da informação e as diversas áreas da empresa para a gestão corporativa das informações. Este trabalho se propôs a operacionalizar uma forma de classificar as estruturas de gestão de informações para BI que são encontradas nas organizações, verificando o efeito de cada tipo de estrutura na qualidade percebida das informações disponibilizadas para as áreas de negócio, bem como o impacto para atividades dos indivíduos nas organizações que utilizam sistemas de BI. Foi realizada uma pesquisa quantitativa em três organizações, cada uma compondo uma amostra de cada tipo de estrutura de gestão de informações. Com a aplicação da técnica estatística de PLS, foi possível obter os efeitos entre as variáveis QI (Qualidade da informação), QGI (Qualidade da Gestão da Informação) e II (Impacto individual), moderados pelo tipo de estrutura de gestão de informações. Apesar de terem sido obtidas diferenças estatisticamente significantes entre as amostras, isto é, que as influências de QGI e QI em II variam estatisticamente de acordo com o tipo de estrutura de gestão de informações, foram pequenas as diferenças absolutas dos efeitos entre as estruturas adotadas em cada organização. Porém, os resultados obtidos nesta pesquisa de caráter exploratório sugerem a necessidade de estudos em uma maior quantidade de organizações, com vários casos para cada tipo de estrutura, a fim de identificar se existe consistência do efeito da variável moderadora nas variáveis analisadas entre diferentes tipos de organizações. / Information systems for business intelligence are designed to collect, organize, prepare and make available information related to internal processes and external environment of organizations. The use of this information is intended to support the process of decision making, business management and innovation of the processes of organizations. Thus, this class of information systems (BI) has the potential to improve individual and organizational performance, being a source of competitive advantage for organizations. The approach to deploy and sustain this class of information of system (BI) cannot be only a sequence of individual projects to make available information required during the scope phase of the project. Demand and delivery management of information necessary for the business requires an ongoing effort to maintain the function of BI aligned with the needs of the organization, through processes that ensure the information availability, use of shared information, information analysis across the organization based on the same concepts, documentation and organization of information, as well as support and training in technical and functional aspects of the systems. In this context, it has emerged the competence centers of information for BI, as a support organization for all areas of business, being the liaison between the area of information technology and the various areas of the company for corporate management of Information. This study proposes to operationalize a framework to classify the structures of information management for BI that are normally found in organizations and check the effect of each type of structure in the perceived quality of the information provided to the business areas as well the impact on individual activities for organizations that use BI systems. It was performed a quantitative study in three organizations, each one composing a sample of each type of management structure information. With the application of the statistical technique of PLS, it was possible to obtain the effects between variables QI (Quality of Information), QGI (Quality of Information Management) and II (Individual impact), moderated by the variable called \"type of information management structure\". Despite having been obtained statistically significant differences between the samples, in other words, that the influence of QGI and QI on II statistically vary according to the type of information management structure, the absolute differences of the effects were small between the respective structures adopted in each organization. However, the results obtained in this exploratory study suggest the need to research a larger number of organizations with multiple cases for each type of structure, in order to identify whether there is consistency in the effect of the moderating variable on the other variables among different types of organizations.

La ética aplicada en el uso de la Big Data

Galarreta Atoche, Mayra Isabel, Vélez Chafloque, Israel Bryan 11 May 2020 (has links)
La presente investigación se centra en exponer las diversas opiniones desarrolladas en torno a la ética y el uso de la Big Data, es decir, los macrodatos. Para ello, se ha realizado una indagación sistemática de fuentes publicadas en un marco temporal comprendido entre los años 2015-2020 con la intención de recuperar los acercamientos más recientes que se han centrado en la relación de estas dos variables. Se han planteado, principalmente, cuatro objetivos que organizan la estructura del trabajo. En un primer momento, se busca establecer un alcance de lo que se entiende por ética y cómo esta se relaciona con las empresas y los negocios a través del concepto de ética empresarial, con todo lo que implica. Luego de ello, se ha planteado la construcción de una definición de cómo se entiende la Big Data, su evolución y usos, además de los beneficios que puede proporcionar su presencia. Se continúa con la explicación de la imagen reputacional de las empresas y la aplicabilidad de las teorías éticas en el uso de los macrodatos. Las principales conclusiones que se desprenden de la investigación es que no hay un consenso hegemónico en la academia respecto al componente ético del uso de la Big Data. Mientras que para algunos no solo se orienta al plano práctico, sino también al prescriptivo, para otros el componente humano es determinante para medir sus implicancias sociales y organizacionales. En todo caso, se puede desligar que los autores coinciden en resaltar la importancia de estudiar y analizar el uso de esta información virtualizada por todas las implicancias que puede tener en diferentes niveles de la vida social y empresarial. / This paper pretends to place in perspective different points of view about the connection between ethic and Big Data use. In order to get to this goal, there has been made a systematic research of published papers on 2015-2020 with the intention to recover most recent approaches about the link of these two research variables. It has been proposed, mainly, four aims to organize this paper. Firstly, it seeks to stablish a scope about what implies Ethics as a concept and how this is related with enterprises or business affairs through the concept of business ethics, with all that it implies. Then, it has been set the Big Data definition as a problem, how it evolves in time, its uses, and the comment of several benefits that its presence can provide in both social and business organization. It is continued explaining the enterprise business image idea and how different ethical theories could be applied on Big Data use. As some authors are immersed to prove how Big Data use respond not only in a practical area but in a prescriptive way, other researchers find that the human factor is determinant to measure its social and organizational consequences. Nonetheless, it is possible to conclude that there is not a consensus about the better way to use or to manipulate people information, but authors concur about the importance of studying and analyzing this subject, because it contains a great impact in different levels of social and business life. / Trabajo de Suficiencia Profesional

BEST LEADERSHIP PRACTICES OF MULTINATIONAL CORPORATIONS IN THE USE OF AUTOMATED MIGRATION TOOLS IN ADOPTION OF COMMERCIAL CLOUD COMPUTING PLATFORMS: A META-ANALYSIS

Ethan Michael Sneider (10197767) 01 September 2021 (has links)
<p>Transitioning to cloud computing is a complex and major effort for large multinational corporations (MNCs). Automated cloud migration tools (ACMTs) have been developed and are evolving to streamline this process. The potential benefits of their use are reported to be significant in terms of cost, time, and business innovation. Academic research on ACMTs and the best leadership practices for their use has been limited. </p><p> </p><p>The purpose of the research was to identify the best leadership practices of MNCs in the use of automated migration tools for the adoption of commercial cloud computing platforms. Adoption of cloud computing is a major technological shift occurring globally, and is still in early stages of growth. Major providers of commercial cloud computing platforms include technological giants such as Microsoft, Amazon Web Services, Google, Oracle and IBM.</p><p> </p><p>A meta-analysis designed research approach focusing on the triangulation of case studies, cloud computing industry data and trends from cloud service providers (CSP) revealed that best practices of leaders within MNCs fall under three main categories: awareness, impact and actions. Further, it was determined that the ACMTs with the most advanced capabilities do not necessarily equate to faster realization of cloud value for the MNC. </p><p> </p>With the continued development of ACMTs and their growing adoption, further study on the role of automation in cloud migration solution deployment will be critical, as ACMT capabilities will continue to mature. No longer the sole domain of becoming a market leader alone, organizations that utilize ACMTs are increasingly doing so just to maintain competitive parity, as the true differentiator in organizational excellence is now in cloud optimization and not simply just getting to the cloud.

Schémas de classification et repérage des documents administratifs électroniques dans un contexte de gestion décentralisée des ressources informationnelles

Mas, Sabine 05 1900 (has links)
Les employés d’un organisme utilisent souvent un schéma de classification personnel pour organiser les documents électroniques qui sont sous leur contrôle direct, ce qui suggère la difficulté pour d’autres employés de repérer ces documents et la perte possible de documentation pour l’organisme. Aucune étude empirique n’a été menée à ce jour afin de vérifier dans quelle mesure les schémas de classification personnels permettent, ou même facilitent, le repérage des documents électroniques par des tiers, dans le cadre d’un travail collaboratif par exemple, ou lorsqu’il s’agit de reconstituer un dossier. Le premier objectif de notre recherche était de décrire les caractéristiques de schémas de classification personnels utilisés pour organiser et classer des documents administratifs électroniques. Le deuxième objectif consistait à vérifier, dans un environnement contrôlé, les différences sur le plan de l’efficacité du repérage de documents électroniques qui sont fonction du schéma de classification utilisé. Nous voulions vérifier s’il était possible de repérer un document avec la même efficacité, quel que soit le schéma de classification utilisé pour ce faire. Une collecte de données en deux étapes fut réalisée pour atteindre ces objectifs. Nous avons d’abord identifié les caractéristiques structurelles, logiques et sémantiques de 21 schémas de classification utilisés par des employés de l’Université de Montréal pour organiser et classer les documents électroniques qui sont sous leur contrôle direct. Par la suite, nous avons comparé, à partir d'une expérimentation contrôlée, la capacité d’un groupe de 70 répondants à repérer des documents électroniques à l’aide de cinq schémas de classification ayant des caractéristiques structurelles, logiques et sémantiques variées. Trois variables ont été utilisées pour mesurer l’efficacité du repérage : la proportion de documents repérés, le temps moyen requis (en secondes) pour repérer les documents et la proportion de documents repérés dès le premier essai. Les résultats révèlent plusieurs caractéristiques structurelles, logiques et sémantiques communes à une majorité de schémas de classification personnels : macro-structure étendue, structure peu profonde, complexe et déséquilibrée, regroupement par thème, ordre alphabétique des classes, etc. Les résultats des tests d’analyse de la variance révèlent des différences significatives sur le plan de l’efficacité du repérage de documents électroniques qui sont fonction des caractéristiques structurelles, logiques et sémantiques du schéma de classification utilisé. Un schéma de classification caractérisé par une macro-structure peu étendue et une logique basée partiellement sur une division par classes d’activités augmente la probabilité de repérer plus rapidement les documents. Au plan sémantique, une dénomination explicite des classes (par exemple, par utilisation de définitions ou en évitant acronymes et abréviations) augmente la probabilité de succès au repérage. Enfin, un schéma de classification caractérisé par une macro-structure peu étendue, une logique basée partiellement sur une division par classes d’activités et une sémantique qui utilise peu d’abréviations augmente la probabilité de repérer les documents dès le premier essai. / The employees of an organization often use a personal classification scheme to organize electronic documents residing on their own workstations. As this may make it hard for other employees to retrieve these documents, there is a risk for the organization of losing track of needed documentation. To this day, no empirical study has been conducted to verify whether personal classification schemes allow, or even facilitate the retrieval of documents created and classed by someone else, in collaborative work, for example, or when it becomes necessary to reconstruct a “dossier”. The first objective of our research was to describe the characteristics of personal classification schemes used to organize and classify administrative electronic documents. Our second objective was to verify, in a controlled environment, differences as to retrieval effectiveness which would be linked to the characteristics of classification schemes. More precisely, we wanted to verify if it was possible to find a document with the same effectiveness, whatever the classification scheme used. Two types of data collection were necessary to reach those objectives. We first identified the structural, logical and semantic characteristics of 21 classification schemes used by Université de Montréal employees to organize and classify electronic documents residing on their own workstations. We then compared, in a controlled experimentation, the capacity of 70 participants to find electronic documents with the help of five classification schemes exhibiting variations in their structural, logical and semantic characteristics. Three variables were used to measure retrieval effectiveness : the number of documents found, the average time needed (in seconds) to locate the documents and the number of documents found on the first try. Results revealed many structural, logical and semantic characteristics common to a majority of personal classification schemes : extended macro-structures, shallow, complex and unbalanced structures, thematic grouping, alphabetical order of classes, etc. An analysis of variance revealed significant differences as to retrieval effectiveness that are related to the structural, logical and semantic characteristics of the classification scheme. A classification scheme characterized by a narrow macro-structure and a logic based on classes of activities increases the probability of finding documents more rapidly. On the semantic level, more explicit denominations of classes (for example, by using definitions or avoiding acronyms and abbreviations) increases the probability of success in finding documents. Finally, a classification scheme characterized by a narrow macro-structure, a logic based on classes of activities, and a semantic that uses few abbreviations minimizes the risk of error and failure in retrieval.

Informations- und Wissensmanagement im Nachhaltigen Landmanagement (IWM im NLM)

Kaiser, David B., Köhler, Thomas, Weith, Thomas January 2012 (has links)
1 EINLEITUNG Der Beitrag beschreibt die Grundgedanken zum Aufbau eines Informations- und Wissensmanagement (IWM) unter Einsatz von Web 2.0 Technologien im Rahmen der BMBF-Fördermaßnahme „Nachhaltiges Landmanagement“ (NLM)1. Aus Sicht des Wissenschaftlichen Begleitvorhabens zur BMBF-Fördermaßnahme werden die konzeptionellen Grundlagen zusammengefasst und erste empirische Untersuchungsergebnisse dargestellt. Die gezielte Implementation und der Transfer von Forschungsergebnissen in die Praxis sind in den letzten Jahren verstärkt in den Fokus von Forschungsvorhaben gerückt, konzeptionell (vgl. z.B. Saywell, & Cotton, 1999) wie förderpolitisch (vgl. z.B. die Statusseminare des BMBF in den fachspezifischen Programmen). Diese Beobachtung ist ebenso für die Forschungs- und Entwicklungsvorhaben im Rahmen der BMBF-Fördermaßnahme NLM zutreffend, wo im Modul B der Fördermaßnahme innovative Konzepte, Strategien, Technologien und Systemlösungen für ein NLM entwickelt werden sollen2, um damit die gesellschaftlichen Herausforderungen und Probleme zu überwinden, die sich durch Klimawandel, Ressourcenverbrauch, die Energiewende oder den demographischen Wandel stellen (vgl. Die Bundesregierung, 2008). [...]

Effekterna av en ISO/IEC 27001-certifiering : Upplevda förändringar bland små svenska organisationer / The effects of ISO/IEC 27001 certification : Perceived changes among small Swedish organizations

Ljunggren, Viktor, Freid, Emil January 2020 (has links)
Samhället idag är mer uppkopplat och hanterar större mängder information än tidigare. Informationen hanteras i större omfattning av IT-system där kraven på säker hantering av information blir allt större. För att hantera informationssäkerhet kan organisationer implementera ett ledningssystem för informationssäkerhet (LIS). Det tar både tid och resurser att designa och implementera ett LIS. För att denna investering ska vara lönsam bör den också ge ett mervärde för organisationer. För att standardisera och specificera uppbyggnaden av LIS har ISO/IEC 27001 (standard för LIS) utvecklats och implementerats av organisationer världen över. Syftet med denna studie är att identifiera vilka förändringar som en ISO/IEC 27001-certifiering leder till hos små organisationer i Sverige. En intervjustudie har utförts med en semistrukturerad intervju som datainsamlingsmetod. Utifrån den insamlade empirin har sex kategorier identifierats och beskrivs tematiskt utifrån varje informant. Studien visar att organisationer får en bättre process och kontroll över informationssäkerhet och en stärkt informationssäkerhetskultur. Utöver detta uppges informationssäkerhet ha förbättrats bland organisationer genom olika säkerhetsåtgärder. Dessutom har kommunikationen med kunder förenklats, när informationssäkerhet diskuteras. Studien undersöker ISO/IEC 27001-certifierings påverkan hos flera organisationer, för att få en diversitet på den insamlade empirin. Detta genomfördes med en informant per organisation, med överblick över både organisationen och certifieringen. Studien undersöker organisationer som redan är certifierade, då organisationen ska ha implementerat ISO/IEC 27001-standarden. Varken certifieringsprocessen, säkerhetsåtgärder, implementationen av eller tillämpningen av ledningssystemet har undersökts i denna studie. / Society today is more connected and handles more information than ever before. The information is handled to a greater extent by IT systems, where the requirements for secure information management have increased. To manage this increase in information flow, organization can implement an information security management system (ISMS). It takes both time and resources to design and implement an ISMS. For this investment to be profitable, it should also provide additional value for companies. In order to standardize and specify the structure of ISMS, ISO/IEC 27001 (Standard for ISMS) has been developed and implemented by companies all over the world. The purpose of this study is to identify the changes that an ISO/IEC 27001-certification leads to for small organisations in Sweden. An interview study has been conducted and semi-structured interviews has been used for data collection. Based on the collected empirical evidence, six categories have been identified and described thematically for each informant. The study shows that organisations get a better process and control over information security and a strengthened information security culture. In addition, information security is said to have improved among organisations through various security measures. In addition communications with customers have been simplified, whenever information security is discussed. The study examines the impact of ISO/IEC 27001-certification on four organisations, in order to ensure diversity of the empirical evidence collected. This was done with one informant per organisation, with an overview of both the organisation and the certification. The study examines organisations that are already certified, since the organisation need to have implemented the ISO/IEC 27001 standard. Neither the certification process, the security measures, the implementation nor the application of the management system have been investigated in this study.

Dobrovolník s velkým "D" - pohodář, nebo obětavec? / A Volunteer with a Big "V" - Laid-back, or Self-sacrificing?

Vondrušová, Gabriela January 2013 (has links)
Volunteering - one of the topics which are still present in the society, as it can be perceived as a unique instrument to solve social challenges or organizing society with its specific conditions. The topic of my diploma thesis, based on the grounded theory method, is the process of building and maintaining the relationship of the volunteer to their voluntary work from the volunteers' perspective. I was curious as to what circumstances or limits accompany the forming of such a relationship in the social context and if certain "prototypes" can be found, which would differ in negotiating their role to their surroundings. In my thesis, I focus exclusively on those volunteers who have been given the "Křesadlo" award for the volunteer of the year, which provides the framework of this relationship. I would like to use my results to enrich the knowledge of volunteering's image, which could be used both on the academic field and when working with volunteers. Keywords: civic sector, volunteering, self-perspective, role, identity, "looking-glass self", norm, defence mechanisms, information management, Křesadlo.

Specializované knihovny v 21. století - entitně-relační model a model systému služeb knihovny / Special libraries in the 21st century - the entity-relationship model and the model of system library services

Římanová, Radka January 2015 (has links)
The dissertation is devoted to the analysis of the environment and the future prospects of special libraries. Knowledge has been achieved by direct observation, conceptual modeling and content analysis of scientific documents. Universum of special library can be expressed as an entity- relational model. Document services, which are based on the theoretical framework of information management, are proving to be the most important service in special libraries. Management of special libraries is based on knowledge of the information needs of the user community and the methodology of library processes. Library services are interconnected and the system can be expressed in the form of mind maps. Processes and services of special libraries can provide data for information-science research.

Kommunikationsstörningar &amp; bristande informationkvalité mellan avdelningar : En kvalitativ fallstudie om kommunikationsprocessen gentemot IT-verktyg

Liethof, Don, Rehnqvist, Jonathan January 2020 (has links)
Fungerande och effektiv kommunikation mellan avdelningar är kritiskt för samtliga verksamheter oberoende av bransch. När en avsändare överför information skall det tolkas utan missförstånd för att undvika onödiga fel i kommunikationsprocessen. God informationskvalité är kritiskt för att säkerställa att informationen inte skall misstolkas av rätt mottagare som den är avsedd till. Denna studie har undersökt informationskvalité och kommunikationsstörningar, där syftet är att identifiera och härleda de konsekvenser som uppstår vid bristande informationskvalité och kommunikationsstörningar. Studien har utgått från ett kvalitativt tillvägagångssätt och är en fallstudie som utgått från ett specifikt fallföretag. Studien skall bidra till ökad förståelse för varför god informationskvalité och effektiv kommunikation utan störningar är betydelsefullt för verksamheten. Den empirisk datan har samlats genom fysiska intervjumetoder. Respondenter från två olika befattningsnivåer och från fyra olika avdelningar har intervjuats som arbetar på fallföretaget. Resultatet av den insamlade empirin visar på att det finns underliggande störningar &amp; barriärer och ineffektiv informationskvalité inom verksamhetens kommunikationsprocesser mellan avdelningar som skapar ogynnsamma konsekvenser. De identifierade konsekvenserna är att fel beslut fattas där även säkerhetsbrister, tidsslöseri, missuppfattningar och stressmoment förekommer inom verksamheten. Studiens resultatet har analyserat efter utvalda teorier angående informationskvalité och kommunikationsbarriärer. Intervjufrågorna har utformats efter de valda teorierna för att öka arbetets tillförlitlighet och upprätthålla konkreta intervjufrågorna i relation till det valda forskningsområdet. Även modellen SMCR tillämpades i studien för att få en ökad förståelse respektive kunskap om hur bristande kommunikation mellan avdelningar påverkar en verksamhet. Valda teorier har sammankopplats i en modell för att illustrera sammanknyttningen inom kommunikationsprocessen och tydliggöra kopplingen till störningar &amp; barriärer respektive informationskvalité.
