With its core in adaptability and change responsiveness, the Agile methodology has become a popular application of the project process within the often volatile environment of today’s software development projects. The Agile methodology emphasizes interaction between project roles over documentation and formal processes. This higher interaction increases the need for functioning information dissemination throughout the entire project process. The study was carried out at a small sized Swedish IT consultancy firm. The company wished to acquire a project management and planning software tool to support the entire project process and all involved project roles. However, awareness of areas in the project process in need of support was not entirely clear. Therefore, the objective of the study was to investigate the company’s application of the Agile project process and identify potential challenges. Furthermore, the objective was to investigate how a project management and planning software tool can support the Agile project process within software development. The thesis was carried out as an abductive case study, where qualitative data collection methods and literature studies were combined. As a result from the study, two main conclusions have been drawn. Firstly: requirements engineering, the customer role, communication, and knowledge transfer were concluded as prominent challenges in the project process in need of increased support. Secondly, a project management and planning software tool can support the project process by: increasing the communication and collaboration abilities, providing holistic and historical project overview, providing a single storage location, and providing structure. Furthermore, the study has also shown that the project management and planning software tool needs to interact with the Agile project process in order to provide successful support. As final contribution, the Interaction model was created. The model visualizes the main areas in which a project management and planning software tool must interact with the Agile process, in order to support the entire project process successfully. / Genom dess anpassningsförmåga och förändringsmottaglighet har den Agila metodiken blivit en populär tillämpning för projektprocessen inom mjukvaruutveckling, en miljö där snabba förändringar tillhör vardagen. Den Agila metodiken framhäver interaktion mellan projektroller  framför  dokumentation  och  formella  processer,  vilket  ökar  behovet  av fungerande informationsspridning genom hela projektprocessen. Studien  har  utförts  hos  ett  mindre  svenskt  IT-konsultföretag,  vilket  önskade  att införskaffa en programvara för ett projektlednings- och planeringsverktyg som kan stötta hela  projektprocessen  och  alla  involverade  projektroller.  Medvetenheten  kring  de områden i projektprocessen som är i behov av stöd var däremot inte helt tydlig. Målet med   studien   var   därför   att   undersöka   företagets   tillämpning   av   den   Agila projektprocessen  och  identifiera  eventuella  utmaningar.  Vidare  var  målet  också  att undersöka hur en programvara för ett projektlednings- och planeringsverktyg kan stödja den Agila projektprocessen inom mjukvaruutveckling. Examensarbetet utfördes som en abduktiv fallstudie där flera kvalitativa datainsamlingsmetoder användes tillsammans med litteraturstudier. Som resultat av studien har två huvudslutsatser dragits. För det första; kravhantering, kundrollen, kommunikation  och  kunskapsöverföring  identifierades som framträdande utmaningar i projektprocessen i behov av ökat stöd. För det andra, att en programvara för ett projektlednings- och planeringsverktyg kan stödja projektprocessen genom att; förbättra  kommunikations-  och  samarbetsmöjligheterna,  ge  en  övergripande  och historisk projektöverblick, fungera som en gemensam lagringsplats och tillhandahålla struktur.  Vidare  har  studien  visat  att  en  programvara  för  ett  projektlednings-  och planeringsverktyg  måste  interagera  med  den  Agila  projektprocessen  för  att  ge  ett effektivt  stöd.  Som  ett  slutligt  bidrag  skapades  "the  Interaction  model",  vilken visualiserar huvudområdena inom vilka en programvara för ett  projektlednings- och planeringsverktyg måste interagera med projektprocessen för att ge ett fullt stöd till processen.

É notório que o emprego de unidades de processamento gráfico (GPU) pode acelerar significativamente métodos numéricos de aplicações científicas. Para suportar essa nova tecnologia, é necessário que programas sejam readaptados, exigindo flexibilidade do código. Nesse trabalho, é apresentada a arquitetura de um programa de elementos finitos (MEF) para a análise de estruturas, com suporte ao processamento em GPU. A orientação a objetos é usada para guiar o desenvolvimento e modelar o código em uma estrutura flexível. A escalabilidade do programa é dada pela extensão de suas funcionalidades através de componentes carregados em tempo de execução. Para ilustrar a robustez do código, o software é aplicado para o estudo de dinâmica estrutural, considerando aspectos complexos de não linearidade de material (plasticidade) e geometria (grandes deslocamentos). A acurácia do código é verificada através da comparação com problemas conhecidos da literatura e com as soluções MEF comerciais (ABAQUS). As comparações mostraram uma boa concordância nos resultados. O speedup da GPU é analisado em relação aos tempos de CPU do próprio programa, sendo observado ganhos de desempenho de até 10 vezes. / It has been recognized that the adoption of graphics processing units (GPU) can significantly boost numerical methods in scientific applications. In order to support such technology, it is necessary to readapt the program, which requires code flexibility. In this work, it is presented the architecture of a finite element (FEM) analysis program for structural analysis with GPU support. Object-oriented design is used to guide development and to build code into a flexible structure. Program scalability is achieved by extensibility of its features, provided by run-time loaded components. In order to demonstrate code robustness, the software is directed to the study of structural dynamics, considering complex non-linear aspects of material (plasticity) and geometry (large displacements). Code accuracy is checked by comparing with known literature problems and with commercial solver packages (ABAQUS). The comparison shows good agreement in the results. The GPU code speedup is analysed against timings of CPU program code, where it is observed performance gain up to 10 times.

Successful projects increase sales, reduce costs, improve quality, customer satisfaction, the work environment; among other benefits. An increasing number of companies use project management as a key strategy for maintaining competitiveness, increasing the value possibility to their business. However, many projects with all the ingredients for success fail. One reason for this is related to failure in assessing the uncertainties by executives, managers and project team. In a typical software development environment it is not different. Thus, the aim of this work is to propose an approach to manage uncertainties in software projects to contribute to their better performance and influence their success. The research method used in this work is based on the principles of Evidence-Based Software Engineering. During the guide conception stage an exploratory literature research on managing uncertainty in software projects and a systematic literature review on the state of the art theme in a more structured way along with an action research conducted in a software development project were conducted. In addition, semi-structured interviews with software industry experts and researchers in the field were carried out in order to obtain improvement to the approach. In the evaluation phase a focus group was conducted to evaluate the proposed approach. The results showed that an exploratory literature review helped to characterize the difference between risk and uncertainty and mapped the uncertainty sources. The systematic literature review found 5 ways to manage uncertainties in projects; 18 practices for project management focusing on reducing uncertainties; a confirmation of the uncertainty sources mapped in primary studies and the relationship between uncertainty and innovative projects was assessed. In the action research there was an application of techniques and strategies in projects and investigation on whether those contributed to uncertainty; in semi-structured interviews the addition of the practical point of view for the approach was evaluated and added. Finally, the focus group was performed to assess the elaborated approach. The results of this research contribute to software project management by defining an approach to uncertainty management, as well as describing strategies and guidelines for team members. / Vários tipos de projetos são propostos, com diferentes objetivos, em que é preciso gerenciálos estrategicamente de acordo com metas organizacionais. Projetos bem sucedidos aumentam as vendas, reduzem os custos, melhoram a qualidade, a satisfação do cliente, o ambiente de trabalho, entre outros benefícios. Assim, um número crescente de empresas utilizam o gerenciamento de projetos como uma estratégia fundamental para manter a competitividade, aumentando a possibilidade de valor aos seus negócios. No entanto, muitos projetos com todos os ingredientes para o sucesso, falham. Um dos motivos porque isso acontece relaciona-se com a não avaliação das incertezas pelos executivos, gerentes e equipe do projeto. Em um ambiente de desenvolvimento de software típico não é diferente. Baseado nisso, o objetivo geral deste trabalho é propor uma abordagem para gerenciar as incertezas em projetos de software, contribuindo assim para um melhor desempenho dos projetos de software e influenciando no seu sucesso. O método de pesquisa adotado neste trabalho está fundamentado nos princípios da Engenharia de Software baseado em evidências. Foi realizada uma pesquisa exploratória da literatura sobre gerenciamento das incertezas em projetos de software. Em seguida, de forma mais estruturada, foi realizada uma revisão sistemática da literatura sobre o estado da arte do tema juntamente com uma pesquisa-ação, conduzida em um projeto de desenvolvimento de software. Além disso, entrevistas semi-estruturadas foram realizadas com especialistas da indústria de software e pesquisadores na área a fim de avaliar as evidências encontradas e adicionar insumos para a abordagem. Na fase de avaliação foi realizado um grupo focal com especialistas que avaliaram a abordagem proposta. Os resultados da revisão da literatura exploratória serviu para caracterizar a diferença entre riscos e incertezas e foram mapeadas as fontes de incertezas. Da revisão sistemática da literatura encontramos 5 formas de gerenciar as incertezas nos projetos e 18 práticas para o gerenciamento de projetos focando na redução das incertezas. Foi realizada uma confirmação das fontes de incertezas mapeadas nos estudos primários e avaliada a relação entre incertezas e projetos inovadores. Na pesquisa-ação pôde-se aplicar técnicas e estratégias em projetos e investigar se essas contribuíram para gestão da incerteza. Nas entrevistas semiestruturadas foi avaliado e adicionado o ponto de vista prático para a abordagem. Finalmente, um grupo focal foi realizado para avaliar a abordagem elaborada. Os resultados desta pesquisa contribuem para a gestão de projetos de software por definir uma abordagem para o gerenciamento de incerteza, bem como descrevendo as estratégias e orientações para os membros da equipe.

The conception phase is one of the most important phases of software projects. In this phase it is determined which software development company will perform a software project. To obtain a software project, companies can have several bidding strategies. This thesis investigates if and how game theory can be a helpful tool to evaluate bidding for software projects. This thesis can be divided into two different parts: a theoretical and a practical. The theoretical part investigates the applicable parts of game theory in this thesis, explains what software projects are, explains the difference between costing and bidding and provides results of a literature survey about bidding behaviour. The practical part introduces a study to investigate strategies and bidding behaviour of software engineers, explains the experimental design that found the study, provides the results of the performed study and a discussion of the results. This thesis concludes that game theory contains some concepts that make it possible to evaluate bidding for software projects. / Jacco Buisman Bonairestraat 32 9715 SE Groningen The Netherlands

Conselho Nacional de Desenvolvimento Científico e Tecnológico / The tasks allocation process is a key activity in project management. Being able to conciliate the people profile, as well their professional aspirations is a real challenge for managers. Software projects differ from the rest because of its intangibility and complexity, characteristics that contribute to the failure of these projects. In addition, such projects depend on skilled and highly specialized manpower and the knowledge to motivate and develop them is an extremely important factor for achieving success in this area. Thus, this document sought to present a model of task allocation in software projects that considers, in addition to organizational goals (cost, time, etc.), the professional aspirations of the participating members. The proposed strategy for research is through the simulation of multi-agent systems, systems generally used for behavioral simulation entities. Through this model was intended to provide the manager a tool to aid in decision making in the process of task allocation in software development companies, allowing them to view different scenarios and strategies, looking for producing a better performance in project implementation and greater people satisfaction. / O processo de atribuição de tarefas é uma atividade chave na gerência de projetos. Ser capaz de conciliar o perfil das pessoas, bem como seus anseios profissionais nesse processo é um desafio para gestores. Projetos de software diferem dos demais devido a sua intangibilidade e complexidade, características que contribuem ao fracasso desses projetos. Além disso, tais projetos dependem de mão-de-obra altamente especializada e capacitada e saber motivá-las e desenvolvê-las é um fator de extrema importância para alcançar êxito nessa área. Dessa forma, o presente trabalho buscou apresentar um modelo de alocação de tarefas em projetos de software que considera, além dos objetivos organizacionais (custos, prazos, entre outros), os anseios profissionais dos membros participantes. A estratégia proposta para a investigação é através da simulação de sistemas multiagentes, sistemas geralmente utilizados para simulação de entidades comportamentais. Com esse modelo pretendeu-se prover ao gestor uma ferramenta de auxílio na tomada de decisão no processo de alocação de tarefas em empresas de desenvolvimento de software, permitindo a visualização de diversos cenários e estratégias, gerando dessa forma melhor desempenho na execução de projetos e maior satisfação dos profissionais.

In a country like Ethiopia, where information and communication systems are in the early stage of development, software projects may face several challenges. Projects may suffer from schedule or budget overrun or unmet specifications, leading to failure. Risk is one of the factors that challenges project performance, and even causes failure. Hence, risk management helps project managers to control the effect of risks. However, risk management appears to be the least practiced component of project management. This study aims at assessing the risk management practice in the Ethiopian software projects. This study was undertaken using a survey conducted on 45 banks, insurance companies and UN agency offices in Addis Ababa, Ethiopia. The findings of the study suggest that formal risk management is not widely practiced in Ethiopian software projects. Only 16% of organisations reported that they applied one or more documented formal risk management techniques. Overall, 67% of organisations were found to exercise one or more risk management process steps. Though the risk management practice was found to be reasonably high, the proportion of organisations that carry out all the risk management process phases, through formal or informal methods, was only 27%, showing that risk management practice in Ethiopia cannot be considered adequate. The study thus recommends that Ethiopian software project managers should give more emphasis for risk management in their project management. The risk items that Ethiopian software projects face most were found to be technical complexity risks, with the highest risk item being use of new technology. This may be an indication that project managers should give adequate attention to the risks arising from technical complexity. No statistically significant relationship was observed between formal risk management and project success, and also between risk management practice and project success. / College of Engineering, Science and Technology / M.Sc.

為提升國內軟體專案生產力和品質，建立度量與分析的機制，本研究參考能力成熟度整合模式(Capability Maturity Model Integration, CMMI)之度量與分析流程領域作為指引，結合GQM (Goal-Question-Metric)及PSM (Practical Software & Systems Measurement)的度量方法論，發展一套提問式驅動度量與分析流程規劃法，稱為QMAP (Questions driven- Measurement & Analysis Process Planning)—運用5W1H (Why, Who, When, What, Where & How) 提問方式，有系統地依據CMMI度量與分析流程的要求，找出軟體專案的成功因素，逐步建立組織內部的度量與分析流程的基準。首先，以某公司之個案情境為例進行背景分析、目標分析和流程分析，接著以使用分析—使用案例及其描述之資訊需求，建議整合運用PSM Insight, MS Project及IBM Rational ClearQuest等工具來支援軟體專案度量與分析流程之自動化。經工具系統之實作展示，再以自我評鑑來檢視QMAP於CMMI度量與分析流程之目標及執行方法的符合程度，而部分未達成的項目則作為未來研究之方向。 / This research proposes a method called QMAP (Questions driven- Measurement and Analysis Process Planning) in order to meet goals and practices in Capability Maturity Model Integration (CMMI). QMAP is about 5W1H questions which begin with why, who, when, what, where and how. Before answering the 5W1H questions, we start with background analysis, goal analysis, and process analysis based on a sample company’s management context. Use Cases are then described as the formal information requirements of the MA process support system. In the implementation, we suggest to integrate some tools, such as MS Project, PSM Insight, and IBM Rational ClearQuest, to facilitate the measurement data collection and analysis activities during the software project development. After illustrating the implementation prototype, a checklist for self-appraisal is presented to identify the compliances of CMMI goals and practices, and the incomplete parts for future research extension.
