Die Krise der Hochschulen scheint seit den frühen 90er Jahren nicht mehr abzureißen. Die angestrebte Strukturreform, die Gesetzesänderungen im Hochschulrahmengesetz und die in der Öffentlichkeit diskutierten Reformansätze machen das sehr deutlich. In dieser Arbeit werden bereits erkannte kritische Erfolgsfaktoren der universitären Anpassung an die Umweltbedingungen aufgegriffen und ausgehend von der gegenwärtigen Situation der Hochschulen ein Ansatz zur Unterstützung der Reformbemühungen vorgeschlagen. Dazu werden Konzepte zur Strukturierung von Handlungsebenen an Universitäten und deren Versorgung mit Entscheidungsrelevanten Informationen mittels adäquater Informations- und Kommunikationstechnologien in Form eines Management-Support-Systems (MSS) vorgestellt. Insbesondere wird die Konzeption eines Online-Lehrevaluationsinstrumentes für die Universität Osnabrück als Teilsystem eines Hochschul-MSS bearbeitet und die Eingliederung des Systems in die IT-Infrastruktur der Hochschule verdeutlicht. Die Erweiterung des Typenspektrums des MSS durch die mittels der Evaluation gewonnenen qualitativen Daten, deren Integration in die MSS-Datenbasis, die Funktionsweise des Evaluationsinstrumentes und der verbundenen Komponenten wird anhand einer prototypischen Implementierung erläutert. Abschließend wird ein Ausblick auf Erweiterungsmöglichkeiten gegeben, die Nutzenpotentiale der vorgeschlagenen technisch-organisatorischen Infrastruktur identifiziert und kritische Erfolgsfaktoren bei deren Einführung respektive Übertragung auf andere Bereiche der Hochschule betrachtet.

Introduction: A trend for organisations to change from single to multiple project management has been observed over the last couple of decades. Organizations shifted their focus from single project management towards the simultaneous management of the whole set of projects as one entity – project portfolio. New multi-project settings require a new management approach and practices to successfully manage a portfolio. A common practice in organizations is to evaluate projects after they had been carried out. At that point not much can be done and it is impossible to improve performance and prevent failure. Hence, problems that occur in projects’ implementation phase remain unsolved and even unidentified. Constant control, review and monitoring of projects’ performance in the implementation phase could lead to the problematic portfolio areas being spotted and timely management decisions being made in order to improve the overall portfolio performance. Problem: How do organisations manage projects within a portfolio that perform poorly in the implementation phase? Purpose: The purpose of this thesis is: to describe to what extent and in what ways organizations control, review and monitor project performances in the implementation phase; to identify if organisations use any methods, tools or techniques in order to spot projects that perform poorly according to their expectations; and to discover what happens to the poorly performing projects in the implementation phase after they were identified. Method: An electronic qualitative questionnaire had been constructed and sent out to the 46 sampled Swedish companies currently running project portfolios. 115 most suitable respondents had been chosen to answer the survey. Frame of Reference: Theoretical framework is built on the literature within project portfolio management field, mostly concerning control, review and monitoring of projects of projects’ performance within their implementation phase; practices used to manage poorly performing projects as well as the value of organizational learning. Conclusion: The research results show that even though majority of the studied organizations are aware and striving towards efficient project portfolio control, review and monitoring, a lot of space for improvement still remains. Results reveal that organizations are trying to keep track of projects’ performance within a portfolio, however, very few poorly performing are identified. Moreover, the management practices for underperforming projects are still very limited if not non-existent.

Os principais problemas enfrentados pelas cidades em relação aos resíduos de construção e demolição (RCD) estão associados à disposição irregular das enormes quantidades produzidas. O descarte clandestino dos RCD pode provocar a degradação dos ecossistemas água, ar e solo. O acúmulo de resíduos espalhados em diferentes locais das cidades leva à proliferação de vetores de doenças com danos à saúde pública. Além disso, provocam problemas nos sistemas de drenagem urbana. Do ponto de vista econômico, os custos de limpeza pública para remoção dos resíduos demonstram a não sustentabilidade do modelo corretivo. Essa situação pode ser explicada pela ausência de políticas específicas de gestão. Com a introdução do marco regulatório nacional para os RCD, vários municípios têm procurado implantar um modelo mais sustentável, mas as dificuldades para operação e manutenção têm inviabilizado sua continuidade. Assim, o objetivo desta pesquisa foi avaliar os modelos de gestão dos resíduos de construção e demolição na Bacia Hidrográfica do Turvo Grande (BH-TG) pertencente a 15ª Unidade de Gerenciamento de Recursos Hídricos (UGRHI-15) do Estado de São Paulo, bem como desenvolver um software para apoio à gestão municipal dos RCD - SISRCD. Ainda dentro da proposta do estudo, também são apresentados a situação dos RCD em Portugal e os resultados da experiência realizada em uma obra predial na cidade de Guimarães. Para estudo na UGHRI-15, foram coletados dados da situação dos entulhos nos 64 municípios integrantes, que permitiram fundamentar e sistematizar a metodologia. Os dados foram levantados nos anos de 2008 e 2009 com aplicação de questionário aos gestores e por meio de visitas aos municípios para levantamentos in loco das áreas de disposição final. Os principais itens avaliados foram os sistemas de manejo em operação, a produção de RCD, os custos com gestão, formas de tratamento e descarte. Com base nos resultados obtidos, dos municípios que fizeram parte desta pesquisa, foi possível concluir que apenas São José do Rio Preto possui um plano integrado de Gerenciamento de Resíduos da Construção Civil, conforme diretrizes da resolução n.º 307 do Conselho Nacional do Meio Ambiente. Por esta razão, a implantação do sistema de apoio à gestão municipal dos resíduos da construção civil - SISRCD - pode ser transformada em excelente ferramenta para orientação e auxílio no controle municipal dessas atividades. O SISRCD é uma proposta original de uma ferramenta computacional cuja principal característica é a simplicidade de utilização pelos usuários a qual, após validação poderá ter ampla aplicação nos mais diferentes municípios do país. / The main problems faced by the cities related to construction and demolition wastes (CDW) are associated to the illegal disposal of huge quantities produced. The illegal CDW discharge may cause water and soil degradation problems. The accumulation of wastes scattered in different city locations leads to diseases caused by vectors proliferation with damage to public health. Moreover, they cause problems in urban drainage systems. From an economic perspective, the costs of public cleaning services for waste removal have indicated the nosustainability of the corrective model. This can be explained by the absence of specific policies for CDW management. By introduction of the national regulatory framework for the CDW, several municipalities have attempted to implement a more sustainable model, however difficulties related tosystem operation and maintenance have not allowed its continuance. So, the purpose of this study was to evaluate models for the management of construction and demolition wastes in Turvo Grande Watershed (RTG) which is included in the 15th Water Water Resources Unit Management (UGRHI-15) of São Paulo State, as well as to develop a prototype system to support municipal management of CDW - SISRCD. The work also includes and overview of Portugal CDW situation and the results of an experience carried out on a building location at Guimarães city - Portugal. Information and data related to construction and demolition wastes from 64 municipalities members of UGRHI-15 were collected in order to support and optimize the methodology. The data were collected for the years 2008 and 2009 based on a questionnaire applied to municipal managers and also technical visits to municipalities along with surveys of final disposal areas. The main evaluated issues encompassed management systems in operation, production of the CDW, management costs, and treatment and disposal models. Based on the results, it appears that only Sao Jose do Rio Preto has an Integrated Waste Management of Construction Plan, in accordance to guidelines of in the resolution 307 of the National Environmental Council. Thus, the implementation of a prototype system to support the management of municipal construction waste - SISRCD - may become an important tool for guidance and assistance to the control of municipal activities. The SISRCD is an original proposal for a computer tool based on a simple user interface. The system after is validation may have a broad application at different municipalities around the country.

Há um consenso entre os pesquisadores atualmente de que as organizações precisam estar constantemente mudando e adaptando as suas operações e estratégias para atender a novos requisitos econômicos e de mercado. A capacidade de uma empresa de mudar rapidamente as suas metas e estratégias e de reconfigurar rapidamente as suas operações é chamada de “flexibilidade estratégica”. Essa capacidade tem sido identificada como um fator crítico para o sucesso das organizações de hoje. Contudo, o apoio da tecnologia da informação à flexibilidade estratégica tem sido limitado. Na maioria das organizações, há ainda uma grande lacuna que separa as atividades de planejamento estratégico das atividades de desenvolvimento de sistemas. Isso reduz a agilidade da companhia em responder a novas necessidades do mercado. Um estudo da literatura em gestão mostra que as necessidades atuais de gerentes em ambientes incertos e mutáveis não tem sido satisfeitas pelos sistemas de apoio à gestão disponíveis hoje. Nesta tese, nós propomos um mecanismo para tornar sistemas da informação “conscientes da estratégia”. Essa consciência estratégica é definida como uma funcionalidade que permite a atualização rápida das funções do sistema em resposta a mudanças estratégicas. Essa funcionalidade também aumenta a capacidade de alinhamento estratégico e monitoramento de desempenho da organização. Mais especificamente, nós propomos uma arquitetura de software que permite que os usuários de um sistema se tornem mais conscientes das necessidades estratégicas da companhia durante a realização do seu trabalho. Nosso foco nesse trabalho é na gestão de processos de negócio e o conceito que nós desenvolvemos é chamado de Gestão de Processos de Negócio Consciente de Estratégia (Strategy-Aware Business Process Management - SA-BPM). A consciência estratégica é obtida por meio de uma infraestrutura modular que muda o comportamento do sistema de gestão de processos em tempo real. O sistema passa a ser capaz de capturar informações derivadas diretamente dos sistemas de apoio à decisão da organização (ex.: sistema de planejamento estratégico). Por meio desse instrumento, as organizações podem desenvolver a capacidade de realizar mudanças frequentes nas suas estratégias e de tornar essas mudanças operacionais de maneira rápida, contribuindo assim para a sua flexibilidade estratégica. / Over the past two decades, management research has demonstrated a growing interest in the subject of uncertainty and in the means employed by organizations to cope with it. There is a consensus among researchers nowadays that organizations must be constantly changing and adapting their operations and strategies to match new market and economic requirements. The ability of a firm to rapidly change its goals and strategies and to readily reconfigure its operations is called “strategic flexibility”. Such ability is being identified as a critical success factor for contemporary organizations. Nevertheless, information technology support for strategic flexibility has been limited. In most organizations, there is still a large gap that separates strategic planning activities from information systems development activities. This reduces the agility of the company to respond to new market necessities. A study of the management literature demonstrates that current requirements of managers in uncertain and changing environments have not been fulfilled by the management support systems available today. In this thesis, we propose a mechanism to make information systems “strategy-aware”. Such strategy awareness is defined as a feature that allows for the rapid update of a system’s functions in response to strategic changes. This feature also improves an organization’s capacity for strategic alignment and performance monitoring. More specifically, we propose a software architecture that makes information system’s users become aware of the company’s strategic necessities while performing their job. Our focus in this work is on business process management and the concept developed by us is called Strategy-Aware Business Process Management (SA-BPM). The strategy awareness is achieved through a modular adaptation infrastructure that changes the behavior of the business process management system at run-time. The system becomes able to capture information derived directly from the organization’s management support systems (e.g., its strategic planning systems). Through our framework, organizations can develop the capacity to make frequent changes to their strategies and to rapidly make these changes operational, contributing to the improvement of their strategic flexibility.

Die Arbeit untersucht die Realisierungsmöglichkeiten der Potenziale des objektorientierten Paradigmas im Bereich der Management Support Systems (MSS). Die Untersuchung konzentriert sich dabei auf die grundlegende Datenhaltungskomponente, das Data Warehouse (DWH) respektive Object Warehouse. Dazu wird im ersten Teil zunächst nach einer ausführlichen Analyse der Begriffslandschaft im Bereich der Management Support Systems und einer geeigneten Neudefinition und Einordnung des Data Warehouse auf den Entwicklungspfad des Data Warehouse eingegangen, bei welchem insbesondere die Anforderungen und Zielsetzungen des Data-Warehouse-Konzeptes herausgearbeitet werden. Darauf aufbauend wird ein generelles, systemunabhängiges Data-Warehouse-Konzept entwickelt und gegenüber den in der Literatur und Praxis vorherrschenden, konventionellen Konzepten bewertet. Basierend auf einer umfassenden Klassifizierung und Analyse des objektorientierten Paradigmas und seiner MSS- und DWH-spezifischen Verbesserungspotenziale erfolgt anschließend die Konzeption für ein Object Warehouse. Angesichts der erheblichen Anzahl bezüglich Konzepten und Zielsetzungen sehr unterschiedlicher Objekt-Paradigmata, muss die gleichwohl notwendige Paradigmen-Diskussion und Integration teilweise beschränkt auf den Teilaspekt der Objectbase Management Systems (OBMS) erfolgen, speziell auf solche, die die geforderten semantischen Modellierungsmöglichkeiten des Objekt-Paradigmas für den Reconciled Object Layer des Data Warehouse unterstützen. Im zweiten Teil der Arbeit werden die in konkreten Projekten gewonnenen Erkenntnisse bezüglich der Umsetzung des Object-Warehouse-Konzeptes in der Praxis vorgestellt und einer kritischen Würdigung unterzogen. Dabei werden erhebliche Diskrepanzen bezüglich der Umsetzung methodischer Konzeptionen in realen Software-Werkzeugen expliziert, was eine umfassende Umsetzung des Object-Warehouse-Konzeptes zur Zeit noch erheblich einschränkt.
