Analysis of creation of an enabling environment within the public sector to improve service delivery through project management : the case of the Department of Correctional Services in the Rooigrond Area Commissioner / Maile Jonathan Phooko

Phooko, Maile Jonathan January 2006 (has links)
The study set out to investigate the infusion of Project Management into public service in order to improve service delivery, and to look at the advantage of using Project Management as a management tool. Enabling legislations were referred to, and brief background was made. The advantage of applying Project Management by the North West Provincial Government was highlighted through a reference of a case study of the province as opposed to the service rendered by DCS in the province. The study used a questionnaire to collect data, 50 employees were surveyed through questionnaires over a period of two weeks. Four areas were covered, that is, the Area commissioner's office, Rooigrond Prison, Mafikeng Prison and Mafikeng Community Corrections. The results revealed that most employees were not competent with Project Management, only few have an idea of what Project Management is. The response from participants exceeded expectations, because all questionnaires were received without any problems. The researcher recommends that Rooigrond Area Commissioner must apply Project Management in its structure to render services, and to offer training to the members in order to empower them. / (MBA) North-West University, Mafikeng Campus, 2006

Para tanto, realizou-se a fundamentação teórica para a compreensão da liderança, do desempenho e da relação entre liderança e desempenho nas organizações, além da caracterização sobre contact centers, buscando discutir os pilares de gestão de pessoas voltada ao desempenho e fatores influenciadores, além da liderança, dos resultados individuais e grupais. O modelo conceitual de pesquisa propõe: caracterizar e identificar a liderança a partir da escolha de algumas abordagens teóricas - a dos estilos de liderança, a abordagem contingencial e a abordagem da nova liderança; caracterizar o desempenho com o foco nos fatores de gestão e fatores pessoais que podem influenciar este desempenho; e entender a influência da liderança no desempenho individual na organização estudada. Os resultados da pesquisa realizada com 270 atendentes indicaram que em relação à liderança, o estilo democrático é o preponderante entre os supervisores, com influência da abordagem contingencial e modelo voltado a uma liderança participativa. Com relação ao desempenho, notou-se que a Contax é uma organização que mantém alto nível de controle e monitoramento sobre os resultados dos funcionários, mantendo métodos de avaliação de desempenho que favorecem a retroalimentação do processo e a melhoria contínua. Além disto, para 76,5% dos respondentes, a organização faz com que os novos funcionários se sintam pertencentes à organização, fato que contribui significativamente para o senso de pertencimento e aumento da produtividade. Os resultados apontaram, por fim, uma grande relação de influência entre a atuação do líder, o seu esti lo, seu modelo de gestão com o resultado e desempenho individual nos atendentes da Contax, com 83,7% dos respondentes concordando com esta afirmação e 73,3% indicando que colocariam esta atuação do líder como um dos três principais fatores geradores de maiores níveis de desempenho. O trabalho finaliza apresentando os resultados obtidos, conclusões e sugestões para a geração de novos estudos envolvendo os temas e o setor de contact center, considerando o tamanho deste mercado e sua importância para a geração de empregos no país. / Salvador

Uma análise sobre a relação risco versus desempenho em governança de TI: estudos de caso em organizações prestadoras de serviços de TI certificadas ISO 20000 / An analysis of risk versus performance relationship in IT governance: case studies on ISO 20000 certified IT services providers

Alves, Carlos Rodrigo Cordeiro 28 April 2015 (has links)
A sustentabilidade de uma organização é uma das principais preocupações de um administrador. Portanto, é preciso analisar o equilíbrio dinâmico entre risco e desempenho. Esta relação deve ser estendida à tecnologia da informação, considerando que sua influência sobre o negócio é crescente. Práticas de governança de TI têm sido adotadas como instrumento para padronizar processos e minimizar riscos. Esta pesquisa teve como foco organizações brasileiras prestadoras de serviços de TI certificadas ISO 20.000. Os principais objetivos foram: elencar os processos críticos da norma para as empresas; o grau de formalismo com o qual são aplicados e identificar fatores de risco e desempenho. O método utilizado foi revisar o uso de conceitos e desenvolver um modelo conceitual sobre eles. A coleta de dados foi realizada em duas fases: questionário on-line e entrevistas com gestores de oito organizações. As conclusões do estudo mostraram que o modelo canônico não é aplicado nas organizações tal qual prescrito, não só por suas idiossincrasias, mas também por necessidades de ajustes nos processos da norma. Os fatores encontrados que contribuem negativamente para isto foram: orientação ao atendimento das necessidades dos clientes e formato da decisão sobre investimentos de TI, enquanto os positivos foram: associar riscos a erros das pessoas; cultura de melhoria contínua e controle sobre mudanças. / Organizational business sustainability is one of the biggest concerns of an administrator, therefore it is needed to analyze the dynamic balance between risk and performance. This relationship must be extended to information technology, considering its growing influence over business. IT governance practices are being adopted as an instrument to standardize processes and minimize risks. This research had its focus on Brazilian IT service provider organizations that are ISO 20.000 certified. Its main objectives were: rank the norm critical processes to companies; formalism degree to which they are applied, and to identify risk and performance factors. The method used was to review concepts usage and developed a conceptual model about them. Data gathering was made in two phases: online questionnaire and interviews with senior managers of eight organizations. Study conclusions showed that this canonic model is not applied by the organizations as it is prescribed, not only because their idiosyncrasies, but also by their adjustments needs on the norm\'s processes. Identified factors that negatively contribute to this were: orientation to customer needs fulfillment and IT investments decision format, while positive factors were: associate risks to people\'s errors, continual improvement culture, and control of changes

Mapping the flow Of Apparel in a Wholesale Company

Akash, Umair January 2013 (has links)
Globalization that diminishes the barriers to trade worldwide has transformed the structure of production and increased the global competition in the textile and apparel industry. Especially, the elimination of quotas on January 2005 has totally changed the whole scenario of the apparel industry. A boom has been noticed in the emerging markets. Buyers shift their maximum orders to the low cost countries to increase their profit margins. China has gained its popularity among the European and American buyers because of the cheap labor and large scales of production and has become the world’s largest exporter of textile and apparel. The traditional competitive factor among the buyers is the lower cost of the product but the changing markets trends and demand volatility pushes the buyers to focus also on quality and lead times in addition to price. Due to the huge competition among the cluster of brands, retailers and wholesalers, lead time is becoming critical as longer lead times increases the risk of bottleneck to sales. China is the most important apparel supplier for the EU (especially Germany, the UK, and France) because it provides the cost benefit to the sourcing companies, but at the same time, it increases the lead times and also has more environmental impact in terms of pollution because of the long geographical distance.This thesis highlights that there is a remarkable rise of the labor cost in China, noticed for the last couple of years, which has reduced the competitive factor of price while sourcing from China. This is also an upcoming challenge for the whole world with regards to sourcing strategies. Many sourcing companies are shifting their shares away from China in order to achieve their desired profit margins. Turkey may be an alternative sourcing destination for the European apparel buyers and wholesalers because of its competitive labor cost, favorable government policies, flexibility, sustainability, and proximity to Europe. In this thesis, a pilot study is carried out to determine the relationship and effects of lead times on sales. This thesis also describes the effects of relationships among the business partners on the supply chain flow. It is noted through several pilot studies that the organizations who work in collaboration with their supply chain partners can significantly improve their supply chain efficiency by reducing the inventories, markdowns, lead times, lost sales, and increasing forecast accuracy. There are several tools in use for collaboration such as Vendor Managed Inventory (VMI), Electronic Data Interchange (EDI), Just in Time (JIT), Customer Relationship Management (CRM), and Collaboration, Planning, Forecasting, and Replenishment (CPFR). In this paper the CPFR implementation steps, benefits, and hindrances are discussed in detail. / Program: Master programme in Applied Textile Management

No. of bitstreams: 1 arquivototal.pdf: 748894 bytes, checksum: 5a3dbe401f04025dc69ba7f621499c0f (MD5) Previous issue date: 2008-03-04 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / In the current context of transformation, the so called knowledge organizations seek to integrate, at least, three important components: infrastructure, people and technology. In this study, it is supposed that the process of knowledge management should consider this trilogy integrated. This research aimed to describe the main flow of operations related to the Analysis of Municipal Accounts in TCE-PB, external controlization of the state of Paraiba, from the perspective of modes of conversion of organizational knowledge. This investigation characterized itself as a basic search, with a mixed qualitative and quantitative as well as descriptive and exploratory approach, also using as technical procedures the bibliographic review, and the single case study method, limited to five Divisions of Monitoring of Municipal Management. The search tools used were the questionnaire, the focus group, quantitative statistical analysis and qualitative analysis of content, respectively. Through this case, it was found the need of technology to be properly harnessed, because it is used merely as tool for serving data without significant support for people, despite a good infrastructure. In addition to conditioning factors of the process of knowledge management, such as centralization of decisions and organizational culture in the public sector, it has shown that the knowledge creation process faces a number of baniers such as the absence of the practice of outsourcing and socialization, due to a misunderstanding of the concepts of socialization and combination. It was conclued that the flow of operations in the review of municipal accounts are handcared lack of incentive to the best practices of dissemination of tacit knowledge between servers and preservation of organizational memory, such as formation of discussion groups, expertises maps and disclosure of creative methods of network analysis. / No atual contexto de transformação, as chamadas organizações do conhecimento buscam integrar, pelo menos três componentes essenciais: infraestrutura, pessoas e tecnologia. Neste estudo, entende-se que o processo de gestão do conhecimento deve considerar essa trilogia integrada. O objetivo da pesquisa foi descrever o fluxo das operações relacionadas à Análise de Prestação de Contas no TCE-PB, órgão de controle externo do Estado da Paraíba, sob a ótica dos modos de conversão do conhecimento organizacional. Tal investigação se caracterizou como uma pesquisa básica, com abordagem mista quantitativo-qualitativa, enfoque descritivo-exploratório, usando também como procedimentos técnicos a pesquisa bibliográfica e documental e o método de estudo de caso único, limitado ao âmbito de cinco Divisões de Acompanhamento da Gestão Municipal do TCE-PB, envolvidas na análise de contas. Como instrumento de pesquisa, para a técnica de coleta e tratamento de dados, utilizaram-se o questionário, o grupo focal e a análise de conteúdo qualitativa e de procedimentos estatísticos, respectivamente. Por intermédio desse caso, foi constatada a necessidade de a tecnologia ser adequadamente aproveitada, pois é utilizada meramente como instrumento de veiculação de dados, sem expressivo suporte para as pessoas, apesar de uma boa infra-estrutura. Além de fatores condicionantes do processo de Gestão do Conhecimento, como centralização das decisões e a cultura organizacional do setor público, evidenciou-se que o processo de criação do conhecimento enfrenta uma série de lacunas, a partir da ausência da prática da externalização e da socialização, bem como da concepção equivocada entre o conceito de socialização e de combinação. Concluiu-se que o fluxo de operações da análise de prestação de contas municipais fica prejudicado pela falta de incentivo às melhores práticas de disseminação do conhecimento tácito entre servidores e à preservação da memória organizacional, tais como: formação de grupos de discussão, mapas de expertises e uso de métodos criativos de análise em rede.

A partir da possibilidade de entender o papel dos gestores escolares na relação com a avaliação em larga escala, assumimos como hipóteses que: se as escolas promovem momentos de estudo e análise dos resultados fornecidos pelas avaliações externas, tais ações deveriam repercutir em melhoria dos índices em médio prazo; se os professores se envolvem no processo de discussão e vêm modificando suas práticas, há variáveis externas e/ ou internas que influenciam nas diferenças de relação com a apropriação das informações oriundas das avaliações em larga escala. O que se busca neste estudo é pesquisar como ocorre a intervenção gestora em quatro escolas de Borba-AM no que se refere ao processo de apropriação dos resultados, quais desafios enfrentam e quais estratégias mobilizam para promover reflexões sobre como os resultados podem ser compreendidos pelo coletivo. Entender o movimento de implementação da avaliação em larga escala a nível estadual e de que forma o que ocorreu nacionalmente influencia nas tomadas de decisão, colocando-se como uma frente estratégica para responder essa questão de investigação. Por meio de uma pesquisa qualitativa, verifica-se a atuação dos gestores no processo de apropriação dos resultados da Prova Brasil nas escolas. Como instrumentos de pesquisa, foram utilizadas a análise documental e as entrevistas semiestruturadas com a coordenadora regional, pedagoga, assessoras pedagógicas, gestores e professores de Língua Portuguesa e Matemática dos alunos do 5º ano do Ensino Fundamental das quatro escolas envolvidas. A análise, sustentada em autores que discutem a ação gestora no contexto da avaliação em larga escala, aponta para o fato de que é necessário aperfeiçoar o processo de apropriação dos resultados das avaliações externas para toda a comunidade escolar, a fim de que essas informações possam ser utilizadas no planejamento pedagógico dos professores, visando avanços na aprendizagem dos estudantes. A partir destas constatações, apresenta-se um Plano de Ação Educacional com intuito de aprimorar a gestão de resultados, com vistas a contribuir para a melhoria da qualidade do ensino ofertado nas escolas amazonenses. / This work, carried out under the Professional Master in Management and Evaluation of Public Education, the Center for Public Policy and Education Evaluation of the Federal University of Juiz de Fora, discusses the results of management in four schools in the state schools of Borba municipality in state of Amazonas. From the possibility of understanding the role of school management in relation to large scale evaluation, we assume as assumptions that, if schools promote moments of study and analysis of the results provided by external evaluations, such actions should be reflected in improved figures in mid-term; if teachers are involved in the discussion process and have been modifying their practices, there are external and / or internal variables that influence the differences in relation to the ownership of the information from the large-scale assessments. What is sought in this study is to investigate how does the management intervention in four Borba-AM schools with regard to the appropriation of the results process, what challenges are facing and what strategies mobilize to promote reflections on how the results can be understood by the collective. Understanding the evaluation of the implementation of large-scale movement at the state level and how what happened nationally influence in decision-making positions itself as a strategic front to answer this research question. Through a qualitative research there is the role of managers in the process of appropriation of the results of the trial Brazil in schools. As research tools have been used to document analysis and semi-structured interviews with the regional coordinator, educator, educational advisors, managers and Portuguese Language and Mathematics teachers of students in the 5th grade of elementary school of the four schools involved. The analysis, based on authors who discuss the management action in the context of evaluation on a large scale, points to the fact that it is necessary to improve the process of appropriation of the results of external assessments to the entire school community, so that the information can be used in educational planning teachers seeking advances in student learning. From these findings, we present an Educational Plan of Action in order to improve the results of management, in order to contribute to improving the quality of education offered in schools Amazonians.

Quality-of-Service Aware Design and Management of Embedded Mixed-Criticality Systems

Ranjbar, Behnaz 12 April 2024 (has links)
Nowadays, implementing a complex system, which executes various applications with different levels of assurance, is a growing trend in modern embedded real-time systems to meet cost, timing, and power consumption requirements. Medical devices, automotive, and avionics industries are the most common safety-critical applications, exploiting these systems known as Mixed-Criticality (MC) systems. MC applications are real-time, and to ensure the correctness of these applications, it is essential to meet strict timing requirements as well as functional specifications. The correct design of such MC systems requires a thorough understanding of the system's functions and their importance to the system. A failure/deadline miss in functions with various criticality levels has a different impact on the system, from no effect to catastrophic consequences. Failure in the execution of tasks with higher criticality levels (HC tasks) may lead to system failure and cause irreparable damage to the system, while although Low-Criticality (LC) tasks assist the system in carrying out its mission successfully, their failure has less impact on the system's functionality and does not harm the system itself to fail. In order to guarantee the MC system safety, tasks are analyzed with different assumptions to obtain different Worst-Case Execution Times (WCETs) corresponding to the multiple criticality levels and the operation mode of the system. If the execution time of at least one HC task exceeds its low WCET, the system switches from low-criticality mode (LO mode) to high-criticality mode (HI mode). Then, all HC tasks continue executing by considering the high WCET to guarantee the system's safety. In this HI mode, all or some LC tasks are dropped/degraded in favor of HC tasks to ensure HC tasks' correct execution. Determining an appropriate low WCET for each HC task is crucial in designing efficient MC systems and ensuring QoS maximization. However, in the case where the low WCETs are set correctly, it is not recommended to drop/degrade the LC tasks in the HI mode due to its negative impact on the other functions or on the entire system in accomplishing its mission correctly. Therefore, how to analyze the task dropping in the HI mode is a significant challenge in designing efficient MC systems that must be considered to guarantee the successful execution of all HC tasks to prevent catastrophic damages while improving the QoS. Due to the continuous rise in computational demand for MC tasks in safety-critical applications, like controlling autonomous driving, the designers are motivated to deploy MC applications on multi-core platforms. Although the parallel execution feature of multi-core platforms helps to improve QoS and ensures the real-timeliness, high power consumption and temperature of cores may make the system more susceptible to failures and instability, which is not desirable in MC applications. Therefore, improving the QoS while managing the power consumption and guaranteeing real-time constraints is the critical issue in designing such MC systems in multi-core platforms. This thesis addresses the challenges associated with efficient MC system design. We first focus on application analysis by determining the appropriate WCET by proposing a novel approach to provide a reasonable trade-off between the number of scheduled LC tasks at design-time and the probability of mode switching at run-time to improve the system utilization and QoS. The approach presents an analytic-based scheme to obtain low WCETs based on the Chebyshev theorem at design-time. We also show the relationship between the low WCETs and mode switching probability, and formulate and solve the problem for improving resource utilization and reducing the mode switching probability. Further, we analyze the LC task dropping in the HI mode to improve QoS. We first propose a heuristic in which a new metric is defined that determines the number of allowable drops in the HI mode. Then, the task schedulability analysis is developed based on the new metric. Since the occurrence of the worst-case scenario at run-time is a rare event, a learning-based drop-aware task scheduling mechanism is then proposed, which carefully monitors the alterations in the behavior of MC systems at run-time to exploit the dynamic slacks for improving the QoS. Another critical design challenge is how to improve QoS using the parallel feature of multi-core platforms while managing the power consumption and temperature of these platforms. We develop a tree of possible task mapping and scheduling at design-time to cover all possible scenarios of task overrunning and reduce the LC task drop rate in the HI mode while managing the power and temperature in each scenario of task scheduling. Since the dynamic slack is generated due to the early execution of tasks at run-time, we propose an online approach to reduce the power consumption and maximum temperature by using low-power techniques like DVFS and task re-mapping, while preserving the QoS. Specifically, our approach examines multiple tasks ahead to determine the most appropriate task for the slack assignment that has the most significant effect on power consumption and temperature. However, changing the frequency and selecting a proper task for slack assignment and a suitable core for task re-mapping at run-time can be time-consuming and may cause deadline violation. Therefore, we analyze and optimize the run-time scheduler.:1. Introduction 1.1. Mixed-Criticality Application Design 1.2. Mixed-Criticality Hardware Design 1.3. Certain Challenges and Questions 1.4.
