Automating managers : the implications of information technology for managers in five manufacturing companies

Moss-Jones, J. January 1987 (has links)
Managers are universally regarded as key to the fortunes of organizations, yet there has been little focus on the effects of information technology (I.T.) on this group. In this research, the implications of I.T. for the work and roles of managers were studied, permanently in office settings, in five manufacturing companies in the Northern Home Counties. The cases provided a wide range of both organizational cultures and I.T. use. Data were obtained largely through 101 semistructured interviews with managers in various hierarchical and functional positions. Supporting material came from questionnaires and documents. and through informal observation on the 49 visits to companies. I.T. consists of several interwoven and rapidly developing computing and communications technologies, and is interacting with the extremely varied environments found in the companies. There is no revolution. Rather I.T. use is growing from its precursors - telex, punched-card machines and earlier computers, and is conditioned powerfully by existing cultures. Gradually, however, the inherent character of the technology is changing practices in general, and management work in particular, in radical ways. The fundamental nature of managers' work is little altered by I.T. It remains fragmented; weakly defined; oral; action orientated. Increased productivity and reduced numbers of staff are consequences of I.T., and these, together with the increase in conceptual and systems skills amongst the work-force, are reducing the hierarchical-authority model of people management, and creating a more "professional-team" culture. The increasing effectiveness of information management that I.T. confers is producing other major consequences for managers. Information management is becoming a central component of their work. Overall, managers are having to adapt to increasingly technological systematised environments, with smaller, more skilled staff teams. The transitions for managers are difficult. especially as companies have given slight attention to preparing managers for these changes, or indeed to management development in general.

Avaliação do impacto do gerenciamento de riscos de TI no desempenho financeiro das empresas : uma análise empírica entre empresas abertas brasileiras

Eichler, Flavio Alberto V. January 2017 (has links)
Considerando a importância da TI no ambiente de negócios e os riscos inerentes ao emprego dessa tecnologia, este estudo visa buscar evidências de melhoria de desempenho de empresas com a realização de gerenciamento de riscos de TI (GRTI). A pesquisa em curso seguiu a metodologia da Hipótese de Eficiência de Mercado, na sua forma semiforte, isto é, utilizando o método de janela de eventos. Com essa metodologia estimaram-se os retornos anormais na valorização das ações de empresas, oriundos da publicação de eventos de GRTI pelas empresas de capital aberto brasileiras, obtidos a partir do site da BMF&BOVESPA. Foram analisadas todas as empresas listadas em todo o período disponível no site, isto é, de 2003 até 2016, perfazendo um total aproximado de 400 empresas em cada ano. Essa análise utilizou ferramentas de busca do próprio site para encontrar anualmente todos os documentos que contivessem menção à palavra risco. Todos os documentos públicos obtidos com essa filtragem foram examinados detalhadamente para identificar evidências de que a empresa realizou, pela primeira vez, ações de GRTI, isto é, de que a empresa anunciou ao mercado que o GRTI passou a fazer parte de suas rotinas operacionais e administrativas. Depois dessa análise pormenorizada de todos os documentos publicados por essas empresas no site da BMF&BOVESPA, chegou-se a 22 empresas que evidenciaram ao mercado que fazem GRTI. Essas 22 empresas foram examinadas à luz da metodologia de janela de eventos. Os resultados obtidos indicam que, no cenário brasileiro, não é possível afirmar que o GRTI traz uma melhora no desempenho financeiro das empresas, uma vez que a hipótese nula de alteração do valor do retorno das ações não foi invalidada. Infere-se que o mercado não percebe uma diferença de valor nas ações dessas empresas, em função dos eventos de GRTI. Com intuito de suportar teoricamente esta pesquisa, foram reunidas as principais pesquisas em governança de TI e GRTI e relacionando-as a um desempenho financeiro empresarial. / Considering the importance of IT in the business environment and the risks inherent in the use of this technology, this study aims to seek evidence of improved performance of companies with IT Risk Management (ITRM). The research followed the methodology of the Market Efficiency Hypothesis, in its semi-strong-form, that is, using the event window method. This methodology was used to estimate the abnormal returns on the valuation of companies' shares, resulting from the publication of ITRM events by Brazilian publicly traded companies, obtained from the BMF&BOVESPA website. All listed companies were analyzed throughout the period available on the site, that is, from 2003 to 2016, approximately 400 companies in each year. This analysis used search tools from the site itself to find annually all documents that contained mention to the word risk. All public documents obtained by this filtering were examined in detail to identify evidence that the company held, for the first time, ITRM actions. That is, the company announced that ITRM became part of their administrative and operational routines. After this detailed analysis of all documents published by these companies from Brazilian stock exchange, 22 companies evidenced to the market that do ITRM. These 22 companies were examined under the event window methodology. The results indicate that, in the Brazilian scenario, it is not possible to affirm that the ITRM brings an improvement in companies’ financial performance, since the null hypothesis of change shares’ return values was not negated. It is inferred that the market does not notice a difference in these companies’ share values due to ITRM events. In order to theoretically support this research, the main studies in IT governance and ITRM were gathered and related to a business financial performance.

The impact of strategic alignment on the performance of public organisations

Al Khalifa, Muneera Mohamed January 2016 (has links)
Today, technology is a key component in resolving a range of strategic issues; organisations are becoming increasingly dependent on Information Technology (IT) to improve their performance. In order to make the most out of the available technology, the continuing need to integrate IT strategies with business strategies remains evident. As illustrated from the extant literature, strategic planning and IT appear to present positive correlations with improved performance of organisations. Whilst there has been a range of research that has attempted to apply concepts such as strategic alignment, it remains that there are very few empirical findings centred on the overall effectiveness and usefulness of this approach. The aim of this study is to examine the impact of strategic alignment between business and IT on organisational performance of public organisations and depicts factors affecting this alignment. The development of the conceptual model, which guided this study, was based on prior research conducted in the field of strategic alignment, organisational performance, Information Systems (IS) success and IT acceptance. The rationale here is that previous research on strategic alignment has mainly focused on the development of models and frameworks and examines them in a suitable context or explores the relationships between the variables of the models. Research has shown the need for further investigation on the impact of strategic alignment on organisational performance. Hence, This study expands the knowledge in this field by examining the impact of the strategic alignment of business and IT on the performance of public organisations using quantitative method approach. Following to the development of the conceptual model, a web survey examines this relationship was sent to 413 executives of Bahrain public organisations. Data was collected using a web-based questionnaire from a sample of 163 participants, i.e. some of whom were IT executives, business executives or both. The results of this study imply a positive impact of strategic alignment on organisational performance of public organisations. It also suggest that IT acceptance and prior IS success significantly influence the strategic alignment in public organisations of Bahrain.

A cultural studies analysis of Logo in education

Agalianos, Angelos S. January 1997 (has links)
Education does not take place in a vacuum, it is a terrain where conflicting ideologies compete and relations of power are inscribed. Despite, however, the accumulation of studies illustrating the social and political nature of schooling, sociological work concerned with educational computing is in short supply; with few exceptions, sociologists of education have not directly addressed educational computing. The development of IT in education in the last two decades has been largely uncritical and the field has been dominated by technocentric approaches. This thesis is an effort to develop a sociological language for understanding educational computing and suggests that the introduction and use of IT in education should be situated within its social, political and cultural context. Appropriating ideas from the sociology of education, sociology of technology and cultural studies, the thesis uses a cultural circuit analysis of Logo progran1I11ing language as a case-study in the sociology of culture in order to illustrate some of the ways in which the introduction of new technologies in education may interplay with the maintenance and/or transformation of existing power relations. The first part of the thesis raises questions that strive to situate technological products -and particularly computers in education- within a sociological paradigm. It establishes four main arguments that run through the whole study: • that most existing accounts of IT in education are inadequate; • that sociology of education and cultural studies can -and should- add to our social perspectives on the use of IT in education; • that technological artefacts used in education are socially constructed and can be analysed in terms of a "circuit of cultural production"; • that we could demonstrate the utility of such a model by running it through the development and implementation of a major IT phenomenon, that is Logo. In the second part of the thesis, analysis is divided in five parts (five analytically distinct "moments"). Through reconstructed accounts of participants and secondary sources, analysis of "moment" 1 (production) demonstrates the contingent and unstable nature of Logo as constantly changing and developing technology in the context of the decision-making processes. Analysis of "moment" 2 (text) discusses Logo as a "text", its "philosophy" for education, and the embodiment of its epistemological principles in the technical design of the language. Analysis of "moment" 3 (marketing/economics) discusses the role of marketing, politics, and economics in the development and evolution of Logo; it illustrates that the activities of mediators like government departments and the microcomputer industrial lobby were crucial to the modification and redevelopment of Logo beyond the context of its initial development. Analysis of "moment" 4 (context) situates the introduction of Logo to mainstream schools within its social and political context suggesting that the disintegration of "progressive" education largely constituted the context for the "decline" of Logo during the process of restructuring of formal education in the late 1970s and 1980s. Against this background, analysis of "moment" 5 (consumption) discusses the ways in which Logo was received in the educational arena and was implicated in the politics of educational innovation, looking into the place that Logo occupied within the institutional and organisational cultures of mainstream schools. Finally, based on the discussion of Logo as a case-study and the findings thereof, the thesis summarises the main analytic and methodological messages and points to directions for further research.

IT Process and Governance Framework Adoption in Ghanaian Firms; Extent of Progress and Influencing Factors

Lumor, Truth January 2012 (has links)
Gradually, the physical and geographically restricted marketplace is eroding and giving room to a more vibrant and competitive virtual marketplace – J.F Rayport and J.J Sviokla referred to it as the ―marketspace‖ (J.F. Payport, 1995). Technological advancement is the causative agent of this rapid change. As customers become increasingly complex and find sustained satisfaction in the marketspace, pressure keeps mounting on enterprises to adjust and seek suitable dance to the new rhythm. More prepared enterprises like e-bay and FEDEX have taken advantage of this rapid change to emerge competitive in the marketspace whist others dawdle behind. Enterprises especially in developing economies like Ghana, are increasingly investing enterprise resources in IT infrastructure, and accompanying applications and services to take advantage of the new marketplace and emerge competitive nationally and perhaps, in the process, gain global competitiveness. Are firms having strategic frameworks that guide these investments? And what are the factors that influence the adoption of these frameworks? Are there enabling national and firm level mechanisms to support IT investments? These are the questions that the research seeks to respond to. The research discovered Ghana’s strategic initiatives aimed at providing enabling infrastructure, regulatory and business environment to support the adoption of ICTs into public and civil service, and to also promote the performance and competitiveness of its industries and firms. At firm level, the research investigated the factors that influence the adaptation and effective implementation of IT Governance frameworks in enterprises. The research found education, external business environment, and extent of IT investment, statistically significant in driving IT process and governance framework adoption. It was therefore, recommended that regulatory institutions, educational institutions, market players and managers of firms contribute to the enhancement of these predictor variables to further improve ICT, IT process and IT governance framework adoption in Ghana. It was also recommended that later research should be undertaken to re-evaluate the performance and progress made by Ghanaian firms, and to possibly discover other drivers of ICT, ITprocess and IT governance framework adoption. / IT Process and Governance framework adoption in Ghana is relatively new. The research identifies Education, Level of IT investment and the Business Environment to be the most influential factors in promoting IT process and governance framework adoption in Ghana. / +233-246655744 / +233 - 201111216
