Gestão de multi-projeto no processo de desenvolvimento de produto

No âmbito da unidade curricular Dissertação/Projeto/Estágio do 2º ano do Mestrado em Engenharia mecânica – Ramo Gestão Industrial do Instituto Superior de Engenharia do Porto, o presente trabalho de dissertação foi enquadrado num projeto de desenvolvimento de ferramentas de apoio à gestão de projetos. O projeto foi desenvolvido no Instituto de Engenharia Mecânica e Gestão Industrial (INEGI) na unidade de Desenvolvimento de Produto e Sistemas (DPS). A realização deste projeto teve como objetivo o desenvolvimento e adequação de ferramentas de apoio à gestão de multi-projeto no processo de desenvolvimento de produto na organização em estudo – o INEGI – DPS. A gestão de projetos tem hoje uma grande importância nos resultados das empresas essencialmente em virtude da necessidade de estas competirem num mundo em grande mudança com concorrentes ferozes, em que a capacidade de responder às mudanças a tempo e de uma forma integrada se torna cada vez mais importante. A atividade levada a cabo pela DPS impõe a necessidade de uma gestão de projetos mais eficaz e eficiente suportada numa gestão de informação centralizada. O presente projeto de investigação teve, numa primeira fase, uma adaptação à organização em estudo. De seguida, foi conduzida uma revisão da literatura com o objetivo de se obter a fundamentação teórica necessária ao desenvolvimento de ferramentas com base nas metodologias lean. Prosseguiu com o levantamento da situação inicial da organização e com a identificação dos problemas existentes na gestão de projetos. Incluiu também uma revisão e análise das ferramentas existentes na unidade em estudo. Este conhecimento permitiu delinear uma visão para guiar o desenvolvimento das ferramentas. Após a definição da visão foi, então, realizado o desenvolvimento das ferramentas de auxílio à gestão multi-projeto na organização. A concretização deste trabalho resultou no desenvolvimento de três ferramentas de auxílio à gestão multi-projeto na unidade. Estas ferramentas tornam o processo de gestão de projetos mais simples e fácil de assimilar, requerendo apenas alguns inputs por parte dos colaboradores. Estas ferramentas estão apoiadas nos pilares do lean, e deste modo estão vocacionadas para reduzir o desperdício, promover a melhoria contínua, aumentar o desempenho global dos vários atores nos projetos de modo a entregar mais valor e qualidade superior com menores custos. Acima de tudo, valorizar o trabalho dos colaboradores, tornando-os mais eficientes, eficazes, motivados e comprometidos com a organização.

Share the fame or share the blame? The reputational implications of partnerships

We use an adverse selection model to study the dynamics of firms' reputations when firms implement joint projects. We show that in contrast with projects implemented by a single firm, in the case of joint projects a firm's reputation does not necessarily increase following a success and does not necessarily decrease following a failure. We also study how reputation considerations affect firms ' decisions to participate in joint projects. We show that a high quality partner may not be preferable to a low quality partner, and that a high reputation partner is not necessarily preferable to a low reputation partner.

Establishing Load Transfer in Existing Jointed Concrete Pavements, HR-1041, 1985

In this paper are described the results of a research project that had the objective of developing construction procedures for restoring load transfer in existing jointed concrete pavements and of evaluating the effectiveness of the restoration methods. A total of 28 test sections with various load transfer devices were placed. The devices include split pipe, figure eight, vee, double vee, and dowel bars. Patching materials used on the project included three types of fast-setting grouts, three brands of polymer concrete, and plain portland cement concrete. The number and spacing of the devices and dowel bars were also variables in the project. Dowel bars and double vee devices were used on the major portion of the project. Performance evaluations were based on deflection tests conducted with a 20,000-lb axle load. Horizontal joint movement measurements and visual observations were also made. The short-term performance data indicate good results with the dowel bar installations regardless of patching materials. The sections with split pipe, figure eight, and vee devices failed in bond during the first winter cycle. The results with the double vee sections indicate the importance of the patching material to the success or failure of the load transfer system: some sections are performing well and other sections are performing poorly with double vee devices. Horizontal joint movement measurements indicate that neither the dowel bars nor the double vee devices are restricting joint movement.

Riskienhallinta toimitusprojektin tarjousprosessissa

Tämän työn tavoitteena on mallintaa toimitusprojektien tarjousprosessia siten, että riskienhallinta on yhtenä olennaisena tekijänä huomioitu. Projektien riskienhallinnalla vaikutetaan siihen, että kaikki projektin sidosryhmät ovat projektin lopputulokseen tyytyväisiä.Tarjousprosessin aikana hyvin pitkälle suunnitellaan ja valmistellaan projektia toteutusvaihetta varten. Tarjousprosessin aikana asiakkaan kanssa käydään läpi useita tarjouskierroksia, joiden myötä suunnitelmat tarkentuvat ja osapuolten välinen kommunikointi on avainasemassa. Riskien tunnistamista ja arviointia suoritetaan jokaisella tarjouskierroksella ennen kuin tarjous luovutetaan asiakkaalle. Riskienhallinta ei pelkästään painotu mahdollisten uhkakuvien käsittelyyn, vaan yhtenä näkökulmana on mahdollisuuksien hyödyntäminen hallitusti. Tätä kutsutaan positiiviseksi riskienhallinnaksi.Projektin lopputuloksen kannalta yksi merkittävimpiä asioita on tietoon, sen tuottamiseen ja ymmärtämiseen liittyvät seikat. Asiakkaan ongelmien ratkaisussa luova ja samalla analyyttinen ote on yksi tae menestykseen.

Asiakasräätälöityjen ratkaisujen toimintamalli

Yhteistyö yli organisaatiorajojen, huolellinen lähtötietojen selvittäminen, täsmällinen tehtävien suorittaminen sekä organisaatiossa olevan tiedon laaja hyödyntäminen ovat projektin onnistumisen kulmakiviä. Usein kuitenkin projekti hautautuu omaan arkeensa keskittyen liikaa tehtävien suorittamiseen, eikä luo katseita ympäristöönsä. Tässä työssä tavoitteena on ollut projekti- ja päätöksentekomallin luominen, joka ohjaa projektia heti alkumetreistä jo ennen kuin päätöstä sen toteuttamisesta on tehty. Tarkoituksena on myös ohjata yhteistyöhön yli organisaatiorajojen ja kaikkien näkökulmien huomioonottamiseen ennen projektin aloituspäätöstä. Malli luotiin konstruktiivisena tapaustutkimuksena ja se nojaa kirjallisuuteen melko laaja-alaisesti. Koska malli tulee ohjaamaan asiakasräätälöintejä toteuttavan organisaation projekteja, viitekehystä rajaavat räätälöinti, tuotehallinta ja ennen kaikkia projektin johtaminen. Tutkimusta varten on tutustuttu kohdeyrityksen prosesseihin ja liitetty konstruktio osaksi näitä prosesseja. Teorian pohjalle luotu konstruktio ratkaisee tutkimusongelman määrittämällä toimintamallin räätälöintiprojektien arvonmääritykseen ja toteutukseen. Se tuo järjestelmällisyyttä projektiehdokkaiden arvon määrittämiseen sekä johdonmukaistaa päätöksentekoprosessia ja projektin toteutusta ottaen huomioon suorien hyötyjen lisäksi epäsuorat hyödyt ja vaikutukset tuotetarjoomaan.

ETO-Tuotekehitysprojektin suorituskyvyn mittaaminen

Tutkimuksen tavoitteena oli selvittää, mitä suorituskyvyn osa-alueita ETO (Engineer To Order) – tyyppinen tuotekehitysprojekti pitää sisällään, ja mitkä niistä ovat projektin onnistumisen kannalta tärkeimpiä, eli niin sanottuja menestystekijöitä. Edelleen näiden tunnistettujen menestystekijöiden pohjalta oli tavoitteena kehittää suorituskyvyn mittausmalli, jonka avulla voisi arvioida ja ohjata projektin ja projektinhallinnan suorituskykyä. Tärkeimmät suorituskyvyn näkökulmat tässä mallissa olivat projektin kannattavuuden -, asiakastyytyväisyyden - ja projektinhallinnan näkökulmat. Malli tehtiin rautatieliikenne toimialalla toimivalle yritykselle, joka asetti omat vaatimuksensa mallille. Tutkimus tehtiin kolmivaiheisesti. Ensimmäisessä vaiheessa tutustuttiin aiempiin tutkimuksiin, joiden pohjalta pyrittiin löytämään projektin menestystekijät, sekä näiden suorituskyvyn analysointiin toimiviksi todetut mittausmenetelmät. Ensimmäisessä vaiheessa tutustuttiin myös alaa ohjaaviin standardeihin, ja niiden asettamiin erityisvaatimuksiin projektien suorituskyvyn mittaukselle. Tutkimuksen toinen vaihe oli tapaustutkimus kohdeyrityksen sisäiselle projektiorganisaatiolle, joka toteutettiin survey-kyselynä. Kyselyn avulla pyrittiin löytämään ne menestystekijät, jotka projektiorganisaation itsensä mielestä olivat kaikkein tärkeimpiä projektin onnistumisen kannalta. Kyselyllä pyrittiin myös selvittämään sidosryhmien välisiä näkemyseroja projektin menestystekijöistä. Kysymykset muodostettiin synteesinä tutkimuksen ensimmäisessä vaiheessa löydetyistä menestystekijöistä ja standardien vaatimista pakollisista mitattavista tekijöistä. Tärkeimmäksi menestystekijäksi kyselyssä nousi projektipäällikön kompetenssi. Kyselyssä vastaajilta kysyttiin myös sitä, minkä menestystekijöiden suorituskykyä heidän mielestään tulisi mitata. Tärkeimmäksi mitattavaksi osa-alueeksi nousi aikataulun tarkka seuranta. Kolmannessa vaiheessa näiden kohdeyrityksen menestystekijöiden pohjalta luotiin mittausmalli, joka pyrkii mittaamaan projektin ja projektinhallinnan suorituskykyä tasapainoisesti valituista näkökulmista. Malli ottaa huomioon erityisesti projektinhallinnan suorituskyvyn vaikutuksen projektin lopputuotteena syntyvien hyödykkeiden laatuun. Kohdeyrityksen kokonaissuorituskyvyn kannalta on erittäin tärkeää parantaa projektien suorituskykyä, johon projektien suorituskyvyn mittaaminen on ratkaisu. Standardien asettamat vaatimukset antavat hyvät lähtökohdat kokonaisvaltaisen mittausjärjestelmän luomiselle.

Public-private partnership investments in dry ports – Russian logistics markets and risks

The investments have always been considered as an essential backbone and so-called ‘locomotive’ for the competitive economies. However, in various countries, the state has been put under tight budget constraints for the investments in capital intensive projects. In response to this situation, the cooperation between public and private sector has grown based on public-private mechanism. The promotion of favorable arrangement for collaboration between public and private sectors for the provision of policies, services, and infrastructure in Russia can help to address the problems of dry ports development that neither municipalities nor the private sector can solve alone. Especially, the stimulation of public-private collaboration is significant under the exposure to externalities that affect the magnitude of the risks during all phases of project realization. In these circumstances, the risk in the projects also is becoming increasingly a part of joint research and risk management practice, which is viewed as a key approach, aiming to take active actions on existing global and specific factors of uncertainties. Meanwhile, a relatively little progress has been made on the inclusion of the resilience aspects into the planning process of a dry ports construction that would instruct the capacity planner, on how to mitigate the occurrence of disruptions that may lead to million dollars of losses due to the deviation of the future cash flows from the expected financial flows on the project. The current experience shows that the existing methodological base is developed fragmentary within separate steps of supply chain risk management (SCRM) processes: risk identification, risk evaluation, risk mitigation, risk monitoring and control phases. The lack of the systematic approach hinders the solution of the problem of risk management processes of dry port implementation. Therefore, management of various risks during the investments phases of dry port projects still presents a considerable challenge from the practical and theoretical points of view. In this regard, the given research became a logical continuation of fundamental research, existing in the financial models and theories (e.g., capital asset pricing model and real option theory), as well as provided a complementation for the portfolio theory. The goal of the current study is in the design of methods and models for the facilitation of dry port implementation through the mechanism of public-private partnership on the national market that implies the necessity to mitigate, first and foremost, the shortage of the investments and consequences of risks. The problem of the research was formulated on the ground of the identified contradictions. They rose as a continuation of the trade-off between the opportunities that the investors can gain from the development of terminal business in Russia (i.e. dry port implementation) and risks. As a rule, the higher the investment risk, the greater should be their expected return. However, investors have a different tolerance for the risks. That is why it would be advisable to find an optimum investment. In the given study, the optimum relates to the search for the efficient portfolio, which can provide satisfaction to the investor, depending on its degree of risk aversion. There are many theories and methods in finance, concerning investment choices. Nevertheless, the appropriateness and effectiveness of particular methods should be considered with the allowance of the specifics of the investment projects. For example, the investments in dry ports imply not only the lump sum of financial inflows, but also the long-term payback periods. As a result, capital intensity and longevity of their construction determine the necessity from investors to ensure the return on investment (profitability), along with the rapid return on investment (liquidity), without precluding the fact that the stochastic nature of the project environment is hardly described by the formula-based approach. The current theoretical base for the economic appraisals of the dry port projects more often perceives net present value (NPV) as a technique superior to other decision-making criteria. For example, the portfolio theory, which considers different risk preference of an investor and structures of utility, defines net present value as a better criterion of project appraisal than discounted payback period (DPP). Meanwhile, in business practice, the DPP is more popular. Knowing that the NPV is based on the assumptions of certainty of project life, it cannot be an accurate appraisal approach alone to determine whether or not the project should be accepted for the approval in the environment that is not without of uncertainties. In order to reflect the period or the project’s useful life that is exposed to risks due to changes in political, operational, and financial factors, the second capital budgeting criterion – discounted payback period is profoundly important, particularly for the Russian environment. Those statements represent contradictions that exist in the theory and practice of the applied science. Therefore, it would be desirable to relax the assumptions of portfolio theory and regard DPP as not fewer relevant appraisal approach for the assessment of the investment and risk measure. At the same time, the rationality of the use of both project performance criteria depends on the methods and models, with the help of which these appraisal approaches are calculated in feasibility studies. The deterministic methods cannot ensure the required precision of the results, while the stochastic models guarantee the sufficient level of the accuracy and reliability of the obtained results, providing that the risks are properly identified, evaluated, and mitigated. Otherwise, the project performance indicators may not be confirmed during the phase of project realization. For instance, the economic and political instability can result in the undoing of hard-earned gains, leading to the need for the attraction of the additional finances for the project. The sources of the alternative investments, as well as supportive mitigation strategies, can be studied during the initial phases of project development. During this period, the effectiveness of the investments undertakings can also be improved by the inclusion of the various investors, e.g. Russian Railways’ enterprises and other private companies in the dry port projects. However, the evaluation of the effectiveness of the participation of different investors in the project lack the methods and models that would permit doing the particular feasibility study, foreseeing the quantitative characteristics of risks and their mitigation strategies, which can meet the tolerance of the investors to the risks. For this reason, the research proposes a combination of Monte Carlo method, discounted cash flow technique, the theory of real options, and portfolio theory via a system dynamics simulation approach. The use of this methodology allows for comprehensive risk management process of dry port development to cover all aspects of risk identification, risk evaluation, risk mitigation, risk monitoring, and control phases. A designed system dynamics model can be recommended for the decision-makers on the dry port projects that are financed via a public-private partnership. It permits investors to make a decision appraisal based on random variables of net present value and discounted payback period, depending on different risks factors, e.g. revenue risks, land acquisition risks, traffic volume risks, construction hazards, and political risks. In this case, the statistical mean is used for the explication of the expected value of the DPP and NPV; the standard deviation is proposed as a characteristic of risks, while the elasticity coefficient is applied for rating of risks. Additionally, the risk of failure of project investments and guaranteed recoupment of capital investment can be considered with the help of the model. On the whole, the application of these modern methods of simulation creates preconditions for the controlling of the process of dry port development, i.e. making managerial changes and identifying the most stable parameters that contribute to the optimal alternative scenarios of the project realization in the uncertain environment. System dynamics model allows analyzing the interactions in the most complex mechanism of risk management process of the dry ports development and making proposals for the improvement of the effectiveness of the investments via an estimation of different risk management strategies. For the comparison and ranking of these alternatives in their order of preference to the investor, the proposed indicators of the efficiency of the investments, concerning the NPV, DPP, and coefficient of variation, can be used. Thus, rational investors, who averse to taking increased risks unless they are compensated by the commensurate increase in the expected utility of a risky prospect of dry port development, can be guided by the deduced marginal utility of investments. It is computed on the ground of the results from the system dynamics model. In conclusion, the outlined theoretical and practical implications for the management of risks, which are the key characteristics of public-private partnerships, can help analysts and planning managers in budget decision-making, substantially alleviating the effect from various risks and avoiding unnecessary cost overruns in dry port projects.

Collaborations complexes : modèle théorique et vérification empirique préliminaire en contexte de projets interdisciplinaires et interorganisationnels

La collaboration constitue une stratégie efficace pour aider les organisations et les individus à évoluer dans des environnements dynamiques et complexes, et génère de nombreux avantages cognitifs, affectifs et pécuniaires. De plus en plus, les équipes de travail sont impliquées dans des collaborations complexes, lesquelles requièrent de transiger à travers les frontières nationales, organisationnelles et disciplinaires. Bien que les collaborations complexes soient de plus en plus courantes en milieux organisationnels et étudiées par les scientifiques, peu d’études empiriques ont été réalisées sur le sujet et la documentation inhérente est disséminée dans divers silos parallèles de connaissances, donnant lieu à des modèles conceptuels divergents et incomplets. L’importance croissante de ces formes de collaboration crée l’impératif scientifique et pratique d’en acquérir une meilleure compréhension ainsi que d’identifier et d’évaluer les conditions et les facteurs qui favorisent leur succès et leur efficacité. Cette thèse vise à combler les lacunes susmentionnées et permettre un avancement des connaissances sur le sujet par l’entremise de deux articles répondant à divers objectifs de recherche. Le premier article avance une définition claire des collaborations complexes, en vue de réduire la confusion entourant ce construit. Il présente également la première revue de documentation sur les facteurs favorisant le succès des collaborations complexes, unifiant les résultats issus de divers contextes et disciplines scientifiques. Cette démarche a permis d’identifier 14 variables clés provenant de 26 études empiriques. À partir de ces données, un modèle conceptuel fondé sur des assises théoriques solides et reconnues en psychologie du travail et des organisations est proposé, offrant ainsi un canevas systémique et dynamique du phénomène ainsi qu’une orientation détaillée des pistes de recherches pertinentes. Le deuxième article part des résultats obtenus dans le premier article afin d’évaluer empiriquement les relations entre certains facteurs clés ayant un impact sur des extrants importants de collaborations complexes. L’étude multiphasique est réalisée auprès de 16 équipes de projets (N=93) interdisciplinaires et interorganisationnelles prenant part à des sessions de travail intensives visant la production de concepts novateurs en design intégré lié au développement durable. Les analyses corrélationnelles montrent des liens positifs entre l’ouverture à la diversité, les processus collaboratifs, la viabilité, la performance d’équipe et la performance de projet, ainsi que des liens négatifs entre les conflits et ces mêmes extrants. De plus, les analyses de médiation multiple révèlent qu’une plus grande ouverture à la diversité influence positivement la viabilité, la performance d’équipe et la performance de projet en favorisant les processus collaboratifs efficaces et en réduisant les conflits. Les implications théoriques et pratiques découlant de ces résultats sont discutées.

Construction management research at the individual-level of analysis: current status, gaps and future directions

Individual-level constructs are seldom taken into consideration in construction management research relating to project performance. This is antithetical to the objectives of properly conceptualizing and contextualizing the research we do because many project performance outcomes, such as the extent of cooperation and level of communication or teamwork are influenced and moderated by individuals’ perceptions, values and behaviour. A brief review of the literature in organizational studies centred on culture, identity, empowerment and trust is offered. These constructs are then explored in relation to project performance issues and outcomes, and it is noted that they are predominantly studied at the project and industry levels. We argue that focusing these constructs at the individual unit of analysis has significant implications for project performance and therefore their effects need to be systematically accounted for in explanations of the success and failure of projects. Far from being prescriptive, the aim is to generate interest and awareness for more focused research at the individual level of analysis in order to add new insights and perspectives to critical performance questions in construction management. To this end, a research agenda is outlined, arguing that construction management research integrating individual-level constructs and broader, macro-contextual issues will help define and enhance the legitimacy of the field.

Uma análise sobre o desempenho de uma unidade de projetos compartilhada numa instituição financeira de grande porte

Na realização deste trabalho foi utilizado o método de estudo de caso para estudar uma grande instituição financeira pública brasileira que decidiu substituir a estrutura organizacional funcional de projetos por outra que pudesse ser compartilhada por outras unidades organizacionais. Esta pesquisa analisa o desempenho desta unidade compartilhada de projetos, uma organização matricial de projetos, criada como um centro de serviços compartilhado. A concentração dos projetos neste centro buscou dentre os benefícios esperados em outros centros de serviço compartilhado a melhoria de desempenho dos projetos, quanto a maior pontualidade, melhor planejamento, controle dos atrasos e maior dedicação aos projetos. Porém não havia indicadores para verificação da melhoria após a implantação deste novo arranjo organizacional e, portanto, não era possível afirmar que seu desempenho havia melhorado conforme esperado. Foram então utilizados novos indicadores que permitiram efetuar o diagnóstico do desempenho dos projetos antes e depois da mudança organizacional. Para isto foram utilizadas as informações dos relatórios de acompanhamento do Escritório de Projetos do período de 2009 a 2013 para obtenção de indicadores de eficiência, eficácia e efetividade. Estes indicadores permitem afirmar que esta unidade compartilhada de projetos é mais eficiente, mais eficaz e mais efetiva que a estrutura organizacional funcional anterior quanto a maior pontualidade, melhor planejamento, menores atrasos e maior dedicação aos projetos.

Práticas operacionais e objetivo de desempenho como influenciadores do comportamento da equipe de projetos

Práticas em gestão de projetos (GP), apesar de amplamente difundidas, utilizadas e pesquisadas, não garantem o desempenho (sucesso) do projeto em suas entregas em tempo e custos conforme planejamento. Observa-se que, apesar do uso extensivo de práticas de GP, falhas em relação ao atendimento do cronograma e orçamento são amplamente relatadas. Portanto, este trabalho tem como objetivo principal analisar a influência das práticas de gestão de projetos e do objetivo de desempenho no Comportamento de Cidadania Organizacional (OCB) da equipe de projetos. As dimensões que compuseram o OCB foram: Ajuda, Iniciativa e Compliance. Para testar a relação entre os fatores de práticas de GP (incipientes ou avançados) e objetivo de desempenho (normal ou desafiador) no comportamento da equipe foi utilizada a metodologia do experimento baseado em cenários (SBRP experiment). A amostra contou com 216 alunos de graduação e pós-graduação em administração. O estudo mostrou que a utilização de práticas em gestão de projetos não influenciou o Comportamento de Cidadania Organizacional da equipe de projetos. Entretanto, o objetivo de desempenho nas dimensões de tempo e custos influenciou o Comportamento Cidadão da equipe de projetos. Além desses resultados, a pesquisa mostrou que características pessoais, como experiência em liderar projetos, influenciou a propensão em aumento do comportamento cidadão mediante uma remuneração adicional. Como contribuição adicional este estudo mostra que existem diferenças de resultados nos diferentes grupos de respondentes (alunos de graduação e pós-graduação em administração), conforme encontrado em outros estudos. A utilização do experimento também foi um diferencial metodológico, em virtude de sua ainda baixa utilização em gestão de operações. Finalmente, este estudo também identificou as principais práticas utilizadas na gestão de projetos.

Interface entre arquitetura bioclimática e decisões projetuais

This research has as its object study focus bioclimatic in architecture and its conection with projects decisions, on what regards to environmental comfort for single-family dwelling. From the analysis of five architectural projects inserted in Natal/RN, warm-moist weather, this research gather informations regarding architectural features guided by shape and space arrengement, which embody important elements for the project design development. Computer simulations assisted as foundation to verify the efficiency grade for these projects strategies from shading analysis. Related strategies for the demands of natural ventilation circulation and thermal mass for refrigeration were analysed as well. Results show that there is an hierarchizing of priorities for the decisions made when it comes to shape and space disposition variables, as well as the way these variables will consider the bioclimatic demands. The analysis, even, show that there is no single way to respond to specific bioclimatic demands, as it points out the value of examination of the projectual solutions throughtout the conception process, in order to achieve an efficient project performance for the envimonment comfort
