This thesis proposes a framework to support the inexperienced student user to undertake the elicitation, analysis and specification of web user requirements. It is designed to support the student during web projects and to encourage more rigorous analysis by documenting web user requirements before the student commences design and implementation. The framework comprises a process meta-model, object model, rules model, support and guidance model, consistency, completeness and correctness model, learning model, student data model and a requirements specification model. The framework was transformed into an automated Computer Aided Web Environment (CAWE) tool and tested on a number of web modules within a Higher Education Institute (HEI). The research programme adopts the Canonical Action Research (CAR) methodology, which involves one or more iterations of diagnosing, action planning, action taking, evaluating and specifying what has been learned through reflection and allows interventions to take place within the next research cycle. Students were active participants in the research programme and contributed to the development of the intervention with continuous feedback. Analysis of usage data generated by the CAWE tool provided a valuable insight into how the framework and support mechanism was used by the students. Main contributions include the extension of knowledge and understanding of Web User Requirements in Web Engineering. Contribution is made to the curriculum of Web Engineering by identifying gaps in knowledge and understanding regarding the lack of analysis techniques used by the student. ii Contribution is also made to Web and User Requirements Engineering by proposing, implementing and evaluating a range of novel methods and frameworks through student collaboration.

We are concerning about mobile devices limitations, especially its reduced screen dimension that complicates the presentation and manipulation of information. The research was based on a collaborative game of questions and answers entitled Warming Up The Brain. The research method used was the action-research. We performed two cycles of research. In the first cycle, we applied visualization techniques of awareness information in a collaborative game, such as peripheral view, telepointers, list of participants, representative icons/avatars, and colors. In the second cycle, were applied filtering techniques of awareness information, considering user context information, such as information about the group, screen size, device orientation, and individual preferences. Based on the filtering techniques it was possible to build an WYSIWIS context-aware interface (What You See Is What I See) interface. Thus, the collaborative game automatically adjusts the content displayed on the screen based on contextual information - automatic reconfiguration. The game was used by 41 students from three different groups. To evaluate visualization and filtering of awareness information, we defined a set of 24 requirements for mobile groupware development. Based on this set of requirements, it is possible to evaluate the usability of techniques for visualization and filtering of awareness information in four main aspects: the presentation of the awareness information, performance of collaborative tasks, users needs, and mobile devices features. / Este trabalho investiga técnicas de visualização e filtragem de informações de percepção em groupwares móveis. Considera-se que as limitações dos dispositivos móveis, em especial sua dimensão de tela reduzida, dificultam a apresentação e a manipulação das informações. A pesquisa foi fundamentada adaptando o jogo colaborativo de perguntas e respostas intitulado Warming Up The Brain. O método de pesquisa utilizado foi a pesquisa-ação. Foram realizados dois ciclos da pesquisa. No primeiro ciclo, foram empregadas técnicas de visualização de informações de percepção no jogo colaborativo, a saber, visão periférica, teleapontadores, lista de participantes, ícones representativos/avatares, e cores. No segundo ciclo, foram empregadas técnicas de filtragem de informação de percepção, considerando informações de contexto do usuário, a saber, informações sobre o grupo, dimensão e orientação da tela dos dispositivos, e preferências individuais. Com base na filtragem das informações de percepção foi possível construir uma interface WYSIWIS (o que você vê é o que eu vejo) sensível ao contexto. Desta forma, o jogo colaborativo ajusta automaticamente o conteúdo apresentado na interface com base nas informações contextuais reconfiguração automática. O jogo foi utilizado por 41 alunos de três grupos distintos. Para avaliar as técnicas de visualização e filtragem de informações de percepção foi definido um conjunto de 24 requisitos para o desenvolvimento de groupwares móveis. Com base neste conjunto de requisitos é possível avaliar a usabilidade das técnicas de visualização e filtragem em função de quatro aspectos principais: a apresentação das informações de percepção; o desempenho das tarefas colaborativas; as necessidades dos usuários; e as características dos dispositivos móveis.

This thesis deals with managerial competencies in one particular company. The thesis is divided into two parts, the practical and the theoretical one. The theoretical part explains basic notions concerning especially competencies in connection with management. In the practical part, analysis of key managerial competencies of the company is carried out. The terrain data collection is drafted on the basis of quantitative research strategy. The aim of the thesis is to characterize key managerial competencies in the particular company and following carrying out of a detail analysis of these key competences at individual managers. In my work, I recommend a proposal of possible competency development, the state emerged as undesirable; in the form of formal education, informal education or in the form of working experience.

Der weltweit steigende Bedarf an Energie und natürlichen Ressourcen, insbesondere an fossilen Brennstoffen und seltenen Metallen, sowie die angestrebte Reduktion des CO2-Ausstoßes führen zu steigenden Preisen für Energie und Rohstoffe. Der Energie- und Ressourcenbedarf muss daher neben der Funktionalität und den Kosten eines technischen Produkts in Planungs- und Entwicklungsprozesse einbezogen werden. Für eine Minimierung des Energie- und Ressourcenbedarfs sind insbesondere die frühen Phasen der Produktentwicklung von großem Interesse, da in diesen Phasen die wesentlichen Eigenschaften eines Produkts für den gesamten Lebenszyklus zu großen Teilen festgelegt werden. Durch die Forderung nach kürzeren Markteinführungszeiten bei gleichzeitigem Anstieg der Komplexität technischer Produkte ist der Einsatz von Softwaresystemen zur Unterstützung der Planungs- und Entwicklungsprozesse unabdingbar. Die Zielstellung der vorliegenden Arbeit ist die Entwicklung und Realisierung von Methoden und Verfahren zur softwaretechnischen Unterstützung ausgewählter Abläufe der Produktentwicklung. Die gewählten Abläufe sind die Ausarbeitung von Anforderungsspezifikationen für technische Produkte, die Priorisierung von Anforderungen sowie die Analyse und Bewertung des Energiebedarfs von Werkzeugmaschinen. Der Schwerpunkt der Methoden und Verfahren liegt einerseits auf der Strukturierung und Koordinierung der Zusammenarbeit von Domänenexperten in den ausgewählten Abläufen der Produktentwicklung und andererseits auf der Erweiterung der Abläufe um Energie- und Ressourcenbetrachtungen. Die softwaretechnische Unterstützung der gewählten Abläufe ermöglicht es, die Komplexität der zu entwickelnden Produkte beherrschbar zu machen und den manuellen Aufwand der Domänenexperten in den Abläufen zu verringern.
