The industrial age was bound to end when the microprocessor was invented. Even though the classical economic theory applies for today as well as for the 1960s, the last thirty years were symptomatic by the change of the fundamental characteristics of the economy and information technology plays a key role in this process. The aim of this thesis was to describe the principles and micro- and macroeconomic phenomena present in the New Economy of today, the challenges that the companies face in this environment and, finally, to conduct a cross-industry analysis on the impact of IT on company's performance, namely value-added. The empirical results did not show any clear patterns among the industries and therefore no significant relationship between the share of information technology assets of total assets and company's value-added could be proven. One of the reasons for that could be the technical issues regarding the statistical measurement of IT which also remains the biggest challenge for the researchers in this field.

O aumento nos investimentos e o crescente avanço da tecnologia da informação (TI) têm elevado o número de empresas que estão utilizando-a como ferramenta estratégica com o intuito de aperfeiçoar o desempenho e obter vantagem competitiva. À medida que esses investimentos tornam-se mais acessíveis financeiramente, mais rápida é a sua popularização entre as micro e pequenas empresas (MPE). Por outro lado, apesar dos benefícios aparentemente óbvios da TI, há dúvidas quanto ao seu impacto, principalmente para as MPE. É nesse contexto que o objetivo geral desta dissertação é medir o impacto dos investimentos em tecnologia da informação nas variáveis estratégicas organizacionais e no desempenho de micro e pequenas empresas. Para atingir esse objetivo, foram identificadas na literatura variáveis estratégicas e de desempenho para elaboração do instrumento de pesquisa. O método utilizado foi a pesquisa survey, e um modelo conceitual foi elaborado e validado por meio de testes estatísticos. A pesquisa foi realizada com 235 MPE, utilizando-se a modelagem de equações estruturais para a avaliação do modelo conceitual e das hipóteses da pesquisa. Constatou-se que há um impacto positivo dos investimentos realizados em TI na gestão de clientes com o desempenho de custos, vendas e produtividade. Detectou-se, ainda, que os investimentos em TI nas MPE impactam principalmente as variáveis Cliente e Eficiência Organizacional Interna, e verificou-se que, quando são realizados os investimentos em TI para o gerenciamento dos clientes e da empresa, maior parece ser o benefício trazido pelos investimentos em TI ao desempenho da organização. / The increase in investments and the growing information technology (IT) advances have raised the number of companies that are using IT. To be successful, organizations are increasingly investing in IT, using as a strategic tool in order to improve performance and to gain competitive advantage. As these investments become more financially accessible, faster is its popularization by micro and small enterprises (SMEs). On the other hand, despite the seemingly obvious benefits of IT, there are doubts about their impact, especially for SME. In this context, the general objective of this work is to measure the impact of investments in information technology in organizational strategic variables and performance of micro and small enterprises. To achieve this goal have been identified in the literature strategic variables and performance for development of the survey instrument. The method used was survey research and a conceptual model was developed and validated through statistical tests. The survey was conducted by 235 SME. We used structural equation modeling to evaluate the conceptual model and research hypotheses. It was identified that there is a positive impact of IT investments in customer management with cost performance, sales and productivity. It was also identified that IT investments in SMEs primarily impact the client variables and Internal Organizational Efficiency and it was found that it is carried out IT investments for managing customers and the management of the company, the greater seems to be brought benefit by IT to organizational performance.

Organizations make large investments in Information Systems (IS) expecting positive impacts to the organisation and its functions. Yet, there exists much controversy surrounding the 'potential' impacts of these systems, with some studies reporting broadly positive impacts of IS across organizations (Barua, Kriebel and Mukhopadhyay 1995; Barua and Lee 1997; Brynjolfsson and Hitt 1996; Lehr and Lichtenberg 1999; Mukherjee, Ray and Miller 2001), while others have shown nil or detrimental impacts (Attewell and Rule 1984; Brynjolfsson and Yang 1996; Cameron and Quinn 1988; Wilson 1993). Various authors have suggested that these conflicting results may be due to poor measurement - E.g. incomplete or inappropriate measures of success (DeLone and McLean 1992; Gable 1996; Melone 1990), lack of theoretical grounding and hence agreement on appropriate measures of success (Bonner 1995; Myers, Kappelman and Prybutok 1998), myopic focus on financial performance indicators (Ballantine, Bonner, Levy, Martin, Munro and Powell 1996; Kaplan and Norton 1996), weaknesses in survey instruments employed (Gable, Sedera and Chan 2003) (e.g., constructs lacking in validity), or (5) inappropriate data collection approach (Seddon, Staples, Patnayakuni and Bowtell 1999; Sedera and Gable 2004) (e.g., asking the wrong people, unrepresentative sample). Enterprise Systems (ES) have over the past decade emerged to be one of the most important developments in the corporate use of information technology. Anecdotal evidence reveals discontent with these large application software packages. Yet Enterprise System investments are seldom systematically evaluated post-implementation; the review process and measures typically being idiosyncratic and lacking credibility. Impacts resulting from 'Enterprise Systems' are particularly difficult to measure, with an Enterprise System entailing many users ranging from top executives to data entry operators; many applications that span the organization; and a diversity of capabilities and functionality. Despite the substantial investments made by organizations and the anecdotal evidence of discontent, systematic attempts to measure their success have been few. The primary objective of this research is to develop and test a standardized instrument for measuring ES-Success. Other related objectives of this research include: (1) to identify the dimensions and measures of ES-Success, (2) to validate a maximally generalizable measurement model and survey instrument for gauging ES-Success; (3) to develop an understanding of the state of Enterprise Systems using descriptive/comparative statistics, and (4) to identify and test an antecedent of ES-Success. With the above objectives, and in attention to the weaknesses identified in past IS-success research, this study follows and extends the 'research cycle' guidelines of Mackenzie and House (1979) and McGrath (1979). The research cycle entails two main phases: (1) an exploratory phase to develop the hypothesized measurement model, and (2) a confirmatory phase, to test the hypothesized measurement model against new data. The two surveys (termed as identification-survey and specification-survey) conducted in the exploratory phase of this research go beyond the activities recommended by Mackenzie and House (1979) and McGrath (1979). A third "confirmation-survey" was completed in the confirmatory phase of the research cycle. The three surveys gathered and analyzed data from six hundred (600) respondents. The purpose of the identification-survey was to discover the salient ES-Success dimensions and measures to include in an a-priori ES-Success model. Data from 137 respondents representing 27 Australian State Government Agencies that had implemented SAP R/3 in the late 1990s were analyzed. The analysis of identification-survey data yielded an a-priori model with 41 measures of 5 dimensions of ES-Success that provide a holistic view across the organization from strategic to operational levels. The specification-survey was employed to validate the a-priori ES-Success measurement model derived in the preceding identification-survey. Employing 310 responses from the same 27 public sector organizations, exploratory data analysis validated 27 measures of success pertaining to the 4 dimensions: information quality, system quality, individual impact and organizational impact. Data for testing the influence of an antecedent of ES-Success was simultaneously gathered during the specification-survey. This analysis, based on the Adaptive Structuration Theory (AST), investigated the influence of Knowledge Management Structures Adequacy (KMSA) on ES-Success. Preliminary results indicate a strong relationship between the Knowledge Management Structures Adequacy and ES-Success. The purpose of the confirmation-survey was to further validate the dimensions and measures of the ES-Success model, using new data, employing confirmatory statistical techniques. Data was gathered from 153 respondents across a large University that had implemented the Oracle Enterprise System, which facilitated further construct validity of the ES-Success measurement instrument was further established using Structural Equation Modeling (SEM).

Organization Performance Analysis Framework (OPAF) is a Metamodel which analyzes performance of organizational structure using Enterprise Architecture Analysis Tool (EAAT). This quantitative analysis is used to find out which structure is good at learning, motivation, efficiency, productivity, etc. and how to change it. Current framework does not include IT and how it affects the organizational structure. This thesis work will try to find out how IT affects organizational structure, directly and indirectly. The effect is translated in Object Constraint Language (OCL) and inserted in the model. The framework IT-OPAF is used to analyze three real life organizations and see the changes in performance when IT is introduced. This will validate the findings and also recognize pattern of the effect of IT on organizational structure.

No. of bitstreams: 0 Previous issue date: 15 / Nenhuma / A utilização de Tecnologias da Informação Móveis e Sem Fio (TIMS) nos processos organizacionais é um fenômeno relativamente recente. Essas tecnologias vêm sendo utilizadas em diversos contextos, para localização, rastreamento, coleta e consulta de dados, entre outras aplicações. No entanto, o resultado de sua utilização, principalmente para as organizações, ainda carece de estudos. Visando contribuir com essa lacuna de conhecimento, este trabalho tem por objetivo avaliar os resultados da adoção de TIMS para a prestação de serviços em empresas públicas, analisando o caso do IBGE. O caso estudado é o de utilização de TIMS para a realização do Censo 2007 pelo IBGE (Instituto Brasileiro de Geografia e Estatística), que consiste em um caso de adoção massiva dessa tecnologia, envolvendo o uso de 82.000 equipamentos móveis – PDAs, o que o caracteriza como um caso raro e significativo para o estudo da temática de pesquisa. A análise do caso indica uma série de resultados que podem ser avaliados tanto sob o ponto de / The use of Mobile and Wireless Information Technologies (MWIT) in organizational processes is considered to be a rather recent process. Those technologies have been applied in several contexts for location, tracking, data collection and analysis, among other usages. However, the outcome of it, especially for organizations, still requires some studies. To contribute to fill that knowledge gap, this paper aims at evaluating the MWIT application results concerning providing services in the public sector, by analyzing IBGE’s case. The study carried out refers to MWIT use by IBGE (Instituto Brasileiro de Geografia e Estatística), in the 2007 census when the technology was massively adopted, by utilizing 82,000 mobile devices – PDAs, which distinguishes it as a singular case, as well as relevant to the purpose of the research. The analysis of the case shows a set of results that may be evaluated from distinguished points of view, depending on the each one of the stakeholders involved, such as the government, or
