According to the Project Management Institute (PMI) , it is estimated that 25 % of global GDP are allocated to the projects, featuring increasingly the recognizing and the importance of this methodology and increasing its diffusion. Organizations that adopt this management methodology seek competitive advantages, new job opportunities and even to conquer other markets. But what it is perceived is that many organizations simply cannot meet deadlines in its planning and, in the presence of this scarcity, this dissertation presents the method of time planning on projects called Critical Chain Method, which is the application of the Constraints Theory in the environmental of projects, in a simulation of its applicability in the planning of activities to build an electrical energy sub transmission line of 69,000 volts. The aim of this study was to compare two methods of project management: PERT / CPM and Critical Chain Method (CCPM) in the building of this line. The methodologies adopted were a case study, seeking to understand by documental analyze of records the shape and the behavior of the planning by PERT / CPM and a experimental research, through planning simulation using the Critical Chain Method. In conclusion, this study showed that the CCPM reduces the deadlines and absorbs the deviations, without compromising the delivery of projects, since there are a commitment of the professionals involved and a radical change in the organizational culture of the enterprise analyzed. / Nos últimos anos muito se tem falado a respeito de gerenciamento de projetos e de como as suas contribuições são importantes para as organizações que buscam excelência e efetividade em seus empreendimentos. Segundo o Project Management Institute (PMI), é estimado que 25% do PIB mundial estejam destinados a projetos, caracterizando cada vez mais o reconhecimento e a importância dessa metodologia e aumentando a sua difusão. As organizações que adotam essa metodologia de gerenciamento buscam vantagens competitivas, novas oportunidades de trabalho e até mesmo a conquista de outros mercados. Mas o que se percebe é que muitas organizações simplesmente não conseguem cumprir os prazos estabelecidos em seus planejamentos, e, diante dessa carência, apresenta-se neste trabalho o método de planejamento de tempos em projetos denominado Método da Corrente Crítica, que é a aplicação da Teoria das Restrições no ambiente de projetos, em uma simulação de sua aplicabilidade no planejamento das atividades de construção de uma Linha de Subtransmissão de energia elétrica de 69.000 volts. O objetivo deste estudo foi confrontar dois métodos de gerenciamento de projetos: o PERT/CPM e o Método da Corrente Crítica (CCPM) na construção dessa linha. As metodologias adotadas foram um estudo de caso, buscando entender através da análise documental de registros a forma e o comportamento do planejamento por PERT/CPM, e uma pesquisa experimental, por meio de uma simulação de planejamento utilizando o Método da Corrente Crítica. Como conclusão, este trabalho mostrou que o método CCPM reduz os prazos e absorve os desvios, sem comprometer a entrega dos projetos, desde que existam um comprometimento dos profissionais envolvidos e uma mudança radical na cultura organizacional da empresa analisada.

O desenvolvimento de produtos e serviços vem recebendo forte pressão do mercado, demandante de lançamentos frequentes e em prazos cada vez menores. Para atender estas novas exigências, a GP deve prover informações úteis para tomadas de decisões em ambientes de múltiplos e complexos projetos, sujeitos a relevantes incertezas e volatilidade. Considerando as oportunidades de melhoria das práticas da GP para lidar com este ambiente instável e ambíguo, o objetivo deste trabalho é propor, utilizando o método de Teoria Fundamentada em Dados (TFD), um framework que prescreva como aplicar de forma combinada dois métodos de GP: a Gestão de Projetos por Corrente Crítica (Critical Chain Project Management - CCPM) e o Scrum. Os resultados obtidos por este trabalho apontam que a integração destes métodos pode potencializar os benefícios e atenuar as fragilidades de cada uma delas em particular, e cujo uso articulado e coordenado pode permitir decisões mais efetivas em ambientes voláteis, incertos, complexos e ambíguos (VUCA - Volatility, Uncertainty, Complexity and Ambiguity) de múltiplos projetos. / Project Management (PM) has gained a major role in the viability of the strategic objectives of organizations. The development of products and services has been under stronger market pressure, requesting frequent releases and in ever-shorter periods. To meet these new requirements, initiatives for maintaining PM as an information provider to make decisions in multiple and complex projects, exposed to relevant uncertainty and volatility, should be sought. Regarding the opportunities for improvement of PM practices to deal with this unstable and ambiguous environment, the objective of this work is to propose, using the Grounded Theory (GT) method, a framework that prescribes how to apply two GP methods in combination: the Critical Chain Project Management - CCPM and Scrum. The results of this work indicate that the integration of these methodologies can enhance the benefits and mitigate the weaknesses of each of them in particular. This hybrid model could permit a better articulation and coordination of the project tasks, allowing effective decisions in multiple project environments affected by volatility, uncertainty, complexity and ambiguity (VUCA).

Para tal, foi desenvolvida uma pesquisa aplicada, de natureza qualitativa, em ambiente real. As variáveis estudadas foram definidas considerando a revisão da literatura científica e um estudo de campo realizado com antecipação à aplicação do modelo, o qual busca, por meio de uma visão sistêmica, gerenciar melhor a incerteza presente na estimativa de tempo das atividades dos projetos. As diretrizes da pesquisa-ação foram usadas para verificar o funcionamento do modelo e para o levantamento dos dados que posteriormente foram analisados por meio da técnica estatística Regressão Logística Binária. Essa técnica possibilitou encontrar o nível de impacto das variáveis de influência sobre a resposta do sistema, assim como as relações entre essas variáveis. Os dados analisados permitem sugerir que o modelo proposto funciona adequadamente e que os resultados obtidos poderiam ser trasladados do contexto estudado para outros contextos, contribuindo desta forma para o aprimoramento do método da Corrente Crítica / Abstract: The present work aims to propose a model for using the Critical Chain concepts for multiple projects management. To this, it developed an applied research in a real environment. Variables were defined considering scientific literature review and a field study carried out in advance of the application model, which seeks, through a systemic view, a better manage of the uncertainty present in the estimated time of project activities. The guidelines of action-research were used to check the performance of the model and the data collection were later analyzed by statistical technique: Binary Logistic Regression. This technique makes possible to find the impact level of influence variables and the relation with de system response, as well the relationships between them. The analyzed data may suggested that the proposed model works properly and that results could be transferred from de studied context to other contexts, thus contributing to the improvement of the Critical Chain method / Doutorado / Materiais e Processos de Fabricação / Doutor em Engenharia Mecânica

This thesis is concerned with the use of some optimization methods in harness racing. In the first part of the thesis, both critical path method and critical chain method of the project management are applied to horse racing projects. Then a comparison is made in order to choose a suitable method under various conditions. As a result, we can suggest improvements in horse racing organization. In order to determine optimal number of racing days, races and other aspects within a season, an optimization model is created in the second part of the thesis. Minimization of cost or maximization of number of starts can be chosen as an objective function. Various constraints are considered.

Thesis deals with evaluation of possibilities and conditions for application of key project management methods. Particular parts involve description and delimitation of chosen project management. Traditional methods that are represented by CPM and PERT methods. Furthermore, the thesis is enriched on the basis facts of the Theory of Constraints, which led to the creation of a separate project management system based on the Critical Chain method. This part is followed by an analysis and comparison of these methods in the phase of planning, managing and controlling from a perspective of single project case. Thesis is followed by the using of selected method in real environment conditions, its implementation and evaluation of risks and economic differences.

Successful projects are characterized by the quality of their planning. Good planning that better takes into account contextual factors allows more accurate estimates to be achieved. As an outcome of this research, a new framework composed of best practices has been discovered. This comprises an open platform that project experts and practitioners can work with efficiently, and that researchers can develop further as required. The research investigation commenced in the autumn of 2008 with a pilot study and then proceeded through an inductive research process, involving a series of eleven interviews. These consisted of interviews with four well-recognized experts in the field, four interviews with different practitioners and three group interviews. In addition, a long-running observation of forty-five days was conceptualized, together with other data sources, before culminating in the proposal of a new framework for improving the accuracy of estimates. Furthermore, an emerging framework – and a description of its know-how in terms of application – have been systematically reviewed through the course of four hundred twenty-five days of meetings, dedicated for the most part to improving the use of a wide range of specific project management tools and techniques and to an improvement in understanding of planning and the estimation process associated with it. This approach constituted an ongoing verification of the research’s findings against project management practice and also served as an invaluable resource for the researcher’s professional and practice-oriented development. The results obtained offered fresh insights into the importance of knowledge management in the estimation process, including the “value of not knowing”, the oft-overlooked phenomenon of underestimation and its potential to co-exist with overestimation, and the use of negative buffer management in the critical chain concept to secure project deadlines. The project also highlighted areas of improvement for future research practice that wishes to make use of an inductive approach in order to achieve a socially agreed framework, rather than a theory alone. In addition, improvements were suggested to the various qualitative tools employed in the customized data analysis process.

Yes / The current turbulent times call for adaptability, especially in non-repetitive endeavours being a vital characteristic of project management. The research organized along five objectives commenced in the autumn of 2008 with a pilot study. Then it proceeded through an inductive research process, involving a series of interviews with well-recognized international experts in the field. In addition conceptualized long-running observation of forty-five days was used, before proposal of a new framework for improving the accuracy of estimates in project management. Furthermore, the framework’s “know-how to apply” description have been systematically reviewed through the course of four hundred twenty-five days of meetings. This achieved socially agreed understanding assured that it may be possible to improve accuracy of estimates, while having flexible, adaptable framework exploiting dependency between project context and conditioned by it, use of tools and techniques.

This thesis deals with application of Critical Chain in IT/ICT Project management in an international IT company. Beginning with a definition of Theory of Constraints and Critical Chain from a theoretical point of view the thesis provides knowledge base for practical implementation of Critical Chain. The thesis proceeds with selection and division of various IT/ICT projects types providing their evaluation according to their usability with CCPM (Critical Chain Project Management). The thesis also contains research and overview of available resources dealing with application of Critical Chain in IT projects management. This research is presented in a form of case studies and also concluded as a summary of both achieved successes and critical success factors that should be taken into account when implementing CCPM. Based on the knowledge acquired from the previous chapters a formal step-by-step procedure defining how to proceed with CCPM in a project was defined. This procedure will be applied in a real project management as a part of this diploma thesis. The thesis also presents analysis of currently used methodology and approaches to project management in the company and using the procedure created in the previous part the methodology is extended by relevant parts of CCPM. These approaches and methodology are formalized in a Methodical Pattern for IS Development (FI) -- CCPM and this pattern is then used for application of CCPM in a software development project. The project is prepared, planned and controlled according to principles of Critical Chain. The thesis captures this process step-by-step including monitoring of the project and its buffers. For evaluation of the Critical Chain implementation in a software development project a set of criteria was developed and used for assessment. Also every member of the given project team was sent a questionnaire to provide feedback. Originally planned comparison of the CCPM project with a project managed by currently used approaches could not, unfortunately, be carried out due to lack of data and their sensitivity. Considering the scope of this thesis, the application of CCPM in a real project represents verification of validity of the Methodical Pattern for IS Development (FI) -- CCPM and the contribution is also in creation of criteria and verification of their usability for evaluation of projects and potential comparison of two or more projects. Based on the practical application of Critical Chain in a real project, suggestions and recommendation for adjustments to current methodology and also further work with CCPM in the company were provided.

O segmento de Consultoria em Engenharia, ao lado das Universidades e Centros de Pesquisas, é um dos pilares do desenvolvimento científico-tecnológico do país e é considerado um dos responsáveis pela otimização de investimentos, redução dos prazos e dos custos de implantação de empreendimentos públicos e privados, industrial ou de infra-estrutura. Atualmente, esses empreendimentos vêm passando por modificações significativas, exigindo cada vez um melhor desempenho de seus contratados, tanto nos aspectos de qualidade, desempenho, prazo e custos, quanto nos aspectos associados aos riscos contratuais, pois tornaram -se freqüentes contratações nas modalidades EPC (engineering, procurement, construction) e \"turn-key\". Neste novo cenário, as organizações precisam ser mais competitivas para sobreviverem às condições impostas pelo mercado, e, neste novo contexto, o gerenciamento de prazos tem-se tornado um fator crítico de sucesso. Esta dissertação desenvolve uma extensa revisão das técnicas de gerenciamento de prazos, com ênfase na etapa de programação, e uma análise comparativa das principais técnicas utilizadas no gerenciamento de projetos. Para isto, tomou-se como referência o caso de um projeto real, contratado mediante a modalidade EPC, em desenvolvimento por uma Empresa de Consultoria em Engenharia. Foi realizada a comparação entre os Métodos do Caminho Crítico, Corrente Crítica, Análises Probabilísticas e de Monte Carlo, abordando a aplicabilidade dessas técnicas neste caso. Ao final é feita uma síntese dos principais resultados alcançados, bem como dos requisitos demandados na aplicação de cada uma destas técnicas. / The segment of Consultancy in Engineering, as well as the Universities and the Research Centers are some of the pillars of the scientific -technological development in the country and they have been responsible for optimizing the investments, reducing the deadlines and the costs of project implementation in the public and private sectors, along with the industrial and infra-structure sectors. Nowadays, these projects have been going through major changes, which have demanded better performances from those who are contracted, in areas such as the quality control, performa nces, time and costs, as well as the contract risks, which more often than ever, have fallen into the EPC category (engineering, procurement, and construction) and the \'turn-key\' category. In this new scenario, companies need to be more competitive to live through the conditions imposed by the market, and, in this new context, time management has turned into a critical success factor. This dissertation develops an extensive review of the time management techniques focusing on scheduling and also a comparative analysis of the most important techniques used in Project Management. To do that, a real project was created as reference case in which the EPC category was defined and was developed by an Engineering Consultancy. A comparison among The Critical Path Method and The Critical Chain, Probability Analysis Method and The Monte Carlo Method was made, and it approached the applicability of these techniques in this case. At the end, there is a summary of the most important outcomes, as well as the necessary conditions to apply each of these techniques.
