Assim, um melhor entendimento e representação estrutural dos requisitos tornam-se fundamental. Logo, esta pesquisa aplica o conceito das técnicas de refatoração de código dentro da Engenharia de Requisitos, que é focado na metodologia XP, por meios das User Stories. O trabalho aplica um conjunto de padrões e regras que permite aos requisitos expressos em cartões CRC serem refatorados através de pré e pós-condições, sendo que esses requisitos são descritos por mapas conceituais (MC) em formato OWL. Por sua vez, os MCs são convertidos em diagramas de classes da UML por meio da UML-MC que formaliza esta transformação. Dessa forma, o ambiente UStory-Refactory automatiza parcialmente o processo de refatoração e permite que os requisitos refatorados / The emergence of new agile methodologies to support systems development, as the Extreme Programming (XP), has been causing impact on software development companies, specially for its flexibility in the requirements changes during the project. Thus, a better understanding and structural representation of the requirements become basic. Then, this research applies the concept of the code refactoring techniques, inside of the Requirements Engineering, which is focused at XP methodology, through the User Stories. The work applies a set of standards and rules that allows the requirements expressed in CRC cards to be refactored through pre and post-conditions, and the requirements are described for conceptual maps (CMaps) in OWL format. In their turn, the CMaps are converted into UML classes diagrams by the UML-MC that formalizes this transformation. This way, the UStory-Refactory environment partially automatizes the refactoring process and allows the refactored requirements to be exported in OWL format, promoting

Currently published statistics focused on the area of software projects are very disturbing. It is alarming that, according to research company Standish Group only 32% of IT projects end successfully. The percentage of cancelled projects, 24%, is even more disturbing. The applied methodology should contribute to the increase success of the software engineering projects. Statistics show that the methodology applied in the work sphere, is currently used by more than 50% of firms. This work shows the development of specific software in a small IT company, which currently is not supported by any methodology of IS / ICT. The primary objective of this work is the evaluation of the methodology best suited to the needs of business presented. The first chapter of the theoretical part deals with the issues of software engineering and is focused mainly on the area of IT projects success rates and related critical factors of software engineering. The second chapter is then devoted to the history of software engineering and describes the important milestones leading to the development of the most well-known life cycle models and methodologies. The main part of the theoretical block is devoted to methodologies of IS / ICT. This passage is particularly concentrating on the meaning of methodologies in the management of development projects. It also focuses on comparing agile and rigorous methodologies and deals with the assessment of appropriate methodologies for the development of IS / ICT in small businesses. The first part of the practical unit focuses on the introduction of the presented company. The following chapters are devoted to analyzing the current state of software engineering of the client, leading to the detection of the major problems of current development. The analysis is followed by chapter, which is devoted to the presentation of five agile methodologies which were selected on the basis of criteria based on client's specific requirements and needs. The final part is devoted to the evaluation of methodologies based on meeting the given criteria and according to the level of support solutions to the problems analyzed. Based on the resulting findings the client is recommended specific methodology and the appropriate procedure outlined in the implementation of the chosen methodology.

Entretanto, revelou baixa uniformidade fenotípica (± 50,0%) e produção de sementes puras (5-10,0%). Através de seleção recorrente, obtiveram-se duas populações (Corte e Pastoreio) com elevada uniformidade fenotípica (= 80,0%) e boa produção de sementes puras (± 30,0%). Para facilitar o uso e o estabelecimento dessas sementes, tornou-se necessário pesquisar o seu comportamento em relação às condições de armazenamento e à deterioração controlada. Foram utilizados para cada híbrido, cinco graus de umidades e três temperaturas (40, 50 e 65°C). Para cada combinação de umidade e temperatura, as sementes foram embaladas em papel de alumínio multifoliado e semeadas periodicamente, permanecendo nas estufas até se obter curvas completas de deterioração. O teste de envelhecimento acelerado detectou diferenças de vigor entre os períodos de tempo para cada híbrido e, entre os híbridos, para 72 horas de envelhecimento. A seleção recorrente não alterou a armazenabilidade das sementes dos híbridos, mas alterou o tamanho das sementes. A seleção recorrente aumentou a qualidade inicial (Ki) e o tamanho das sementes na população de Pastoreio (plantas mais baixas e mais perfilhadas), sendo que o inverso ocorreu na população de Corte (plantas mais altas e menos perfilhadas). As constantes obtidas para os híbridos Corte, Paraíso e Pastoreio foram: Ke = 8,417; 7,735; 8,285; Cw = 5,037; 4,658; 4,522; Ch = 0,02309; 0,01969; 0,03655;Cq = 0,000436; 0,000403; 0,000300. Foi possível obter uma equação única de viabilidade para os híbridos, com constantes iguais a: Ke = 8,033; Cw = 4,662; Ch = 0,02544; = 0,000386 / Abstract: The interespecific hybrid Pennisetum purpureum (elephant grass) x P. glaucum (pearl millet) has been developed aiming to get the rusticity and high forage production of elephant grass and the high production of pure seeds of pearl millet. However, it revealed low phenotypic uniformity (around 50.0%) as well as low pure seed production (5 -10.0%). A recurrent selection scheme has been applied, resulting in two populations (Cutting- and Grazing-types), showing high phenotypic uniformity (around 80.0%) and a good pure seed production (around 30.0%). In order to allow the using and the establishment of those hybrid seeds, it has been necessary to analyze their performances in relation to storage conditions and controlled deterioration. Five moisture content levels and three storage temperature (40, 50 and 65°C) have been used for each hybrid. Seed sub samples for each moisture content and storage temperature combination were sealed in laminated aluminum foiled packets and stored at those temperatures until complete survival curves have been obtained. Accelerated aging test revealed vigour differences among storage periods for each hybrid as well as at 72-hour period among the hybrids. The recurrent selection has not changed seed storability of the hybrids however altered their seed sizes. The recurrent selection increased seed initial quality (Ki) and seed size for Grazing-type population (lower and high-tillered plants); however inverse results were observed at Cutting-type population (higher and low-tillered plants). Viability equation constants estimated for hybrids Cutting-type, Paraíso and Grazing-type were: e = 8,417; 7,735; 8,285; Cw = 5,037; 4,658; 4,522; Ch = 0,02309; 0,01969; 0,03655;Cq = 0,000436; 0,000403; 0,000300, respectively. It has been feasible estimating the viability equation for the hybrids, through the constants Ke = 8,033; Cw = 4,662; Ch = 0,02544; = 0,000386 / Mestrado / Tecnologia Pós-Colheita / Mestre em Engenharia Agrícola

Agile methods change the software processes. Agile processes such as Scrum, ExtremeProgramming (XP), Open Unified Process (OpenUP) etc. have techniques that improve softwarequality. No doubt that the purpose of these techniques is to inject quality assurance into theproject under development. This thesis presents quality assurance techniques in Open UnifiedProcess (OpenUP) along with comparative study to extreme programming (XP) for agilesoftware development. OpenUP is an agile and unified process that contains the minimal set ofpractices that help teams to be more effective in developing software. It assists to achieve qualityby an iterative and incremental approach with artifacts, checklists, guidelines, disciplines androles. On the other side XP emphasizes on values such as communication, feedback, respect,and courage. In addition, XP prescribes a collection of techniques, which aim to improvesoftware quality. Both these processes have the same purpose, to develop software that meets the stakeholder’sneeds and expectations, however they uses different approaches to achieve their goals. Thisthesis compares both processes in four different points of view, by comparing their qualitytechniques, focus in time, and cost of usage and social perspective. We have proposed an extrarole of the quality coordinator (QC) in OpenUP/XP. QC can support and coordinate project inall quality assurance activities. The objective of an extra role is to use the knowledge of QC toachieve highest possible product quality in software development process.Keywords: Agile Development, Quality assurance (QA), Open unified process (OpenUP),extreme programming (XP), Quality coordinator (QC)
