Produtos e serviços oferecidos pelas organizações modernas são geralmente projetados, implantados e mantidos por meio de infraestruturas de Tecnologia da Informação (TI) de grande escala. Além de obter o melhor desempenho dos produtos e serviços oferecidos, é essencial que essas organizações façam uso de práticas adequadas para o gerenciamento dos recursos que compõem as tais infraestruturas. Para esse m, foram propostos recentemente alguns padrões e bibliotecas de melhores práticas para o gerenciamento de infraestruturas e serviços de TI. Entre as mais amplamente aceitas, tanto da academia quanto na indústria, vale destacar o Information Technology Infrastructure Library (ITIL). Um ponto comum na maioria desses padrões e bibliotecas é a preocupação explícita com os riscos relacionados as atividades de TI. Lidar proativamente com eventos adversos e favoráveis que possam surgir durante as operações cotidianas pode evitar, por exemplo: atrasos na a implantação de serviços, extrapolação no custo de atividades, falhas previsíveis nos recursos manipulados, e consequentemente, desperdício de dinheiro. Apesar da sua importância, o gerenciamento de riscos em ambientes de TI, na prática, geralmente sofre pela falta de automação e padronização. Habitualmente...

Atualmente, o ambiente extremamente dinâmico e altamente competitivo, no qual as organizações estão inseridas, aumentou expressivamente a importância da Tecnologia da Informação (TI). Aliada a isto, a crescente complexidade das infraestruturas de redes e serviços, também conhecidas como infraestruturas de TI, tornaram a Gerência de Serviços de Tecnologia da Informação indispensável a qualquer organização. Nesse cenário, coletâneas de boas práticas e processos foram desenvolvidas visando a obter o melhor desempenho dos produtos e serviços oferecidos. Entre as coletâneas amplamente aceitas, tanto na academia quanto na indústria, vale destacar a Biblioteca de Infraestrutura de Tecnologia da Informação (i.e., Information Technology Infrastructure Library, ITIL). Dentre os processos descritos na ITIL, o Gerenciamento de Mudanças é de suma importância para as organizações. Tal processo é responsável por padronizar o planejamento, o agendamento, a implementação e a avaliação de mudanças no ambiente de TI. Ainda que a adoção das boas práticas proporcione significativas melhorias, a ocorrência de falhas em procedimentos de mudanças não pode ser negligenciada. Para tratar eventuais falhas é proposto o processo de Gerenciamento de Problemas...

Change is an absolutely essential component of product development. However, some changes are too difficult to manage. It is contended that the difficult changes stem from the emergence of novelty. The significance of novelty is that it is not immediately apparent and can be overlooked. It is a common element in disruptive technology, knowledge management, and firefighting research. This work examines the effects of emergent novelty in a complex product development system. In order to do this a framework is developed to categorize potential types of novelty that are encountered. In addition, a unique perspective on the concept of organizational capability is introduced. What makes it unique is the idea that organizational capability is composed of the capacity to do work and the ability of actors to use that capacity. "Organizational infrastructure" is used to speak more concretely about organizational capability. These conceptual models are used to analyze the events of three case studies developed from actual projects in the Imaging & Printing division of Hewlett-Packard. Through the case analysis it is shown there is significant pressures to approach development as if all novelty is understood. However, by doing so almost guarantees problems late in development if latent novelty exists. It is speculated that the addition of excess capacity to the organizational infrastructure will allow for greater novelty detection. This in turn should decrease the complications from resolving issues related to the emergence of novelty.; by Steven M. Gilbert.; Thesis (S.M.)--Massachusetts Institute of Technology...

Information technology (IT) can be a key contributor for the successful implementation of business strategies. However, companies normally find it hard to synchronize their evolving business strategies with the capabilities in IT. This thesis analyzes the key contributors to the problems in synchronizing business strategy and Information Technology and suggests both management and technical frameworks for an agile IT infrastructure that can stay in sync with the evolving business strategy. Agility in IT infrastructure means the ability for the infrastructure to accommodate evolving needs and business strategies without significant re-architecture. There is no magic bullet that could induce agility into an IT infrastructure and its management. But, this thesis studies the best practices in management and technology which are being used by industry leaders successfully.; by Biju Kalissery.; Thesis (S.M.)--Massachusetts Institute of Technology, System Design and Management Program, 2007.; Includes bibliographical references (leaves 43-44).

Ever since the introduction of the Internet in 1994, one of the defining characteristics of the global economy, particularly in the US, is a dramatic increase in expenditures on Information Technology. While this trend is expected to continue, a major issue for companies of all sizes is the manner in which precise forecasting of future IT cost may be undertaken. The present thesis investigates the possibility that a set of the essential deterministic cost drivers with varying weighted factors may prove capable of estimating total IT infrastructure costs. An online questionnaire was developed for this purpose, and was used to survey senior IT leadership teams. The data collected from this survey was then computed with Analytical Hierarchy Process (AHP) to illustrate the relative importance of different cost drivers. The study revealed three primary findings. First, that a set of essential deterministic cost drivers with varying weighted factors could be used as a general tool for estimating the total cost of IT infrastructure. Second, these different sectors prioritize cost drivers differently from each other. In the Financial Services sector, for instance, the security of the IT network was reported to be of greater importance than the service call response time. In the Technology sector...

This book aims to help policy makers take advantage of the opportunities presented by increased cross-border trade in information technology (IT) services and IT-enabled services (ITES). It begins by defining the two industries and estimating the potential global market opportunities for trade in each. Then it discusses economic and other benefits for countries that succeed in these areas, along with factors crucial to the competitiveness of a country or location, including skills, cost advantages, infrastructure, and a hospitable business environment, and examines the potential competitiveness of small countries and of least developed countries specifically. The volume also discusses policy options for enabling growth in the IT services and ITES industries. Appendix A introduces the Location Readiness Index (LRI), a modeling tool to help countries assess their IT and ITES industries. Finally, appendix B presents an analysis of the IT and ITES industries in Indonesia and Kenya as an illustrative application of the LRI.

This study assesses the current state of Public Financial Management and Accountability (PFMA) systems in Indian urban local bodies. It identifies, analyzes, and documents good practices, focusing on their existing context, success factors, and replicability. It is important to mention that urban governance in India is a state subject and there are vast differences in the levels of reform that have achieved in different states. For the purpose of comparison, this study has developed good practice benchmarks in each PFMA area and used those to compare practices across Urban Local body (ULB)s. The study analyzes linkages between the legislative, budgeting, implementation, reporting, and oversight process in urban local bodies. Benchmarks and indicators have been developed for each strategic area. Analysis of policy, practice, and progress in each strategic area has also been conducted. This study synthesizes existing literature on PFMA in urban local bodies, identifies key PFMA areas where focused attention was required...

Corridor efficiency is important to the competitiveness of most of the African economies, especially those that are landlocked. Corridors can be defined as a collection of routes linking several economic centers, countries and ports. While some are only road transport corridors, most of them include more than one mode of transport. The Sub-Saharan Africa Transport Policy Program (SSATP) places emphasis on the facilitation of inter-state trade along corridors. It particularly focuses on identifying impediments to the efficient movement of traffic and seeks to promote appropriate strategies for minimizing hurdles to such movement. This objective is also consistent with the Millennium Development Goals (MDGs) and the Almaty Plan of Action. This concept paper reviews the legal and institutional options for establishing corridor management groups and proposes a framework for establishing such groups along all major transport corridors. Some of the lessons have emerged from the existing corridor management arrangements: (i) corridor groups interventions are problem solving and the operational procedures should encourage this objective and retain flexibility necessary to be responsive; (ii) working groups can be formed on an ad hoc basis to address specific issues and disbanded once the objective met; and (iii) the group organization should ensure public-private interaction at all levels. A three-tier corridor management institution is proposed for regional transport corridors without any arrangement. The institutional hierarchy would comprise a stakeholders group...

This study presents the vision and implementation recommendations for the electronic identity based service delivery framework (EISDF) in Vietnam. It also delineates the roles to be played by the diverse stakeholders (private, public, development community, etc.) in the field. The study recommends various relevant and innovative electronic identity (eID) services that can be implemented to transform and enhance the accountability and efficiency of service delivery across sectors. These recommendations are based on the stocktaking of international experiences and identified possibilities based on the country assessment. Special emphasis is placed on eID systems that operate on mobile phones, and on those that have the potential of being scaled up by both the public and private sectors in Vietnam. The eID systems can help reduce identity fraud and enable individuals to avail of services more securely in a variety of contexts as in mobile banking and mobile applications for health care.

Infrastructure management agencies are facing multiple challenges, including aging infrastructure, reduction in capacity of existing infrastructure, and availability of limited funds. Therefore, decision makers are required to think innovatively and develop inventive ways of using available funds. Maintenance investment decisions are generally made based on physical condition only. It is important to understand that spending money on public infrastructure is synonymous with spending money on people themselves. This also requires consideration of decision parameters, in addition to physical condition, such as strategic importance, socioeconomic contribution and infrastructure utilization. Consideration of multiple decision parameters for infrastructure maintenance investments can be beneficial in case of limited funding. Given this motivation, this dissertation presents a prototype decision support framework to evaluate trade-off, among competing infrastructures, that are candidates for infrastructure maintenance, repair and rehabilitation investments. Decision parameters’ performances measured through various factors are combined to determine the integrated state of an infrastructure using Multi-Attribute Utility Theory (MAUT). The integrated state...

Policy makers are often confronted with a myriad of factors in the investment decision-making process. This issue is particularly acute in infrastructure investment decisions, as these often involve significant financial resources and lock-in technologies. In regions and countries where the infrastructure access gap is large and pubic budgets severely constrained, the importance of considering the different facets of the decision-making process becomes even more relevant. This paper discusses the trade-offs policy makers confront when attempting to prioritize infrastructure investments, in particular with regard to economic growth and welfare, and proposes a methodological framework for prioritizing infrastructure projects and portfolios that holistically equates such trade-offs, among others. The analysis suggests that it is not desirable to have a single methodology, providing a single ranking of infrastructure investments, because of the complexities of infrastructure investments. Rather, a multidisciplinary approach should be taken. Decision makers will also need to account for factors that are often not easily measured. While having techniques that enable logical frameworks in the decision-making process of establishing priorities is highly desirable...

The report looks at Lesotho, a predominantly mountainous, land-locked, poor country with a small population, limited natural resources, and a very fragile ecology. It has low gross national income, and a significant poverty level. To ameliorate this condition, the government has embarked on a pro-poor, growth strategy that includes public, and private investment in infrastructure. It explores the level of private participation at this phase in the evolution of the reforms, which is considerable, given the country's small size, limited institutional capacity, and lack of public and private investment capital. Telecommunications has recorded the most significant reform of any of the infrastructure sectors. Other than telecommunications, reforms in other sectors have not advanced significantly. Not surprisingly, the report identifies specific lessons learned from the telecommunications sector, and examines their relevance to reform efforts under way in the other sectors. In summary, this report finds that private participation in infrastructure could offer Lesotho three key advantages: 1) augmenting budget resources in cases where the private sector undertakes to finance projects...

This document is designed to promote the development of infrastructure services in Honduras, with the aim of improving the country's competitiveness and contributing to poverty reduction. Its central argument is that Honduras needs a significant increase in private investment in infrastructure services, which should take place in a more competitive environment, and be subject to an adequate legal and regulatory framework. The study details the progress to date in Honduran infrastructure sectors, identifying the principal problems that exist and outlining a strategy for their solution. It proposes a general set of principles that should guide the provision of infrastructure services. In addition, it recommends specific policies for each sector. The document's scope includes the following services: transportation, water and sanitation, electricity, and telecommunications. Part 1 presents an overview of general themes related to the development of infrastructure services and to private participation in all the sub-sectors. Part 2 presents an analysis of the current situation of the four infrastructure services covered in this study. One of the major recommendations is the need to establish participative and transparent planning...

Amid a shifting policymaking environment from private to public, volume one of this report discusses how public policies could attract more and better private investments. In attracting back private capital, this report argues that Brazil must do three things. First, it must eliminate remaining regulatory bottlenecks and policy uncertainties in selected sectors. Secondly, design infrastructure concessions to avoid "excessive" renegotiations while simultaneously guaranteeing an adequate rate of return for investors and protecting consumers' welfare. And finally, strengthen the quality of the regulators for technically sound and coherent decision-making processes. Volume two is the background report and looks at infrastructure statistics in Brazil and international benchmarks, regulatory policy issues, contract negotiations, and gives conclusions and policy implications on these topics.

peer-reviewed; New technologies, notably service oriented architectures and Web services, have enabled a third wave of business process management (BPM). Supporters have claimed that BPM is informed by complexity theory with the outcomes that business processes can evolve and adapt to changing business circumstances as well as coevolve with the IT infrastructure. As a consequence it has been suggested by BPM adherents that the businesslIT divide will be obliterated through a process-centric approach to systems development. In this paper we trace the evolution of BPM and its associated technologies and argue that a complex adaptive systems view of business processes and IT infrastructure in general and a coevolutionary view based on Kauffman 's NK[C] model in particular, may provide a more sound basis for BPM and IT infrastructure management. The paper concludes by considering the limitations of coevoutionary theory in the BPM context and proposes areas for future work, including an injection of social theory to address issues such as human agency and the role of social structures.

We investigate the options for enhancing the welfare of small farmers in Thailand through subsidies of irrigation infrastructure. Enhanced water storage and irrigation can significantly improve yield and the welfare of the farm community by providing a more reliable water supply during growing periods. Generally speaking, such enhancements require subsidies from the government or other organizations since farmers are not able or willing to finance infrastructure development themselves. In order to maximize the effectiveness of such subsidies it is important to understand how farmers will react to alternative policies. We develop a two-tier approach to this problem. First, we use a government-level optimization model to identify the set of subsidies and water pricing policies that maximizes a stated measure of aggregate social welfare. This government-level model relies on a farm-level model that determines how individual small farmers will react to the policy alternatives. The farm-level model combines hydrologic, economic, and agronomic features since it considers how hydrologic variability affects crop yield, which in turn affects the farmer's utility. Policy decision variables considered in the government subsidy/pricing model include 1) water price and the number of farms served by public storage facilities (i. e. a water supply reservoir and enhanced in-stream storage)...

nvesting in IT infrastructure is one of the most challenging tasks facing senior managers who often feel ill equipped to make these decisions. Investing in the right infrastructure at the right time enables rapid implementation of future electronically based business initiatives and cost reduction of current business processes. This paper presents a framework for senior executives to view IT infrastructure in business terms and to lead in making investment decisions. By studying 180 electronically based business initiatives in 89 top performing enterprises we identified the specific infrastructure capabilities needed for different types of business initiatives and how this capability is provided as an integrated IT infrastructure. An integrated IT infrastructure has ten clusters of IT infrastructure services fine tuned to the enterprise's set of electronically based business initiatives. Using the frameworks for describing IT based business initiatives...

El objetivo de este ensayo es establecer relaciones teóricas entre diferentes teorías y campos teóricos, la Gestión del Portafolio de TI (GPTI) y sus dimensiones. Los orígenes de la GPTI están fundamentados en los estudios referentes a la teoría moderna de portafolio, que sostiene la atribución de las inversiones en dimensiones, para las cuales se realizaron las relaciones teóricas citadas a seguir. La infraestructura fue relacionada con la teoría institucional, como consecuencia de la semejanza entre las organizaciones actuales debido a la utilización de las mismas infraestructuras de TI. La transaccional fue relacionada a la teoría de la producción, pues ofrece subsidios para permitir el entendimiento de las relaciones entre los inputs (inversiones en TI) y los outputs que esas inversiones proporcionan. La informacional fue relacionada al campo teórico cualidad de la información (QI), en el cual fueron analizados los beneficios de esa dimensión bajo las dimensiones de la QI. Y la estratégica fue relacionada a la visión basada en recursos (RBV), por causa de la relación de esta dimensión con aspectos relacionados a la competitividad. Así, las propuestas realizadas en este ensayo no pueden ser consideradas como verdades absolutas...
