Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Software development organizations are involved in different scenarios with distinct projects in relation to specific project characteristics and demands. There isn´t a software process model appropriate for all projects and/or organizations. The best process depends of the project context. Situational Method Engineering (SME) proposes the building of specific software development methods for each project according to its situational characteristics from method fragments stored in a repository. This work proposes a systematic approach for building a specific development software process for each project through tailoring process based on SME concepts, called OSPTA Octopus SME Process Tailoring Approach. OSPTA uses stored method fragments which include practices recommended by agile and planned process. These fragments are retrieved according to one or more tailoring criteria (tailoring process requirements) and are prioritized from contextual factors defined by Octopus Model. The technique used for this prioritization is Analytic Hierarchy Process (AHP) technique to guide the process engineers in choosing the best fragments to include into organization s standard software process (PSPO). A metamodel was proposed to define method fragments. A support tool was developed to validate the proposed approach through case studies which use project risks as tailoring criteria. / As organizações de desenvolvimento de software estão envolvidas em um ambiente dinâmico, com diferentes cenários de acordo com as características e demandas específicas de cada projeto de software. Não há um processo de software que atenda as necessidades específicas de todos os projetos e/ou organizações. Assim, a adequação de um processo de desenvolvimento de software depende do contexto do projeto. Situational Method Engineering (SME) propõe a construção de métodos de desenvolvimento de software específicos para cada projeto de acordo com as características situacionais dos mesmos a partir de fragmentos de métodos armazenados em um repositório. Este trabalho propõe uma abordagem sistemática para a construção de processos de desenvolvimento de software específicos para cada projeto a partir da adaptação de processos, com base em conceitos de SME, chamada OSPTA Octopus SME Process Tailoring Approach. OSPTA utiliza fragmentos de métodos armazenados em um repositório, os quais incluem práticas preconizadas por processos ágeis e planejados. Tais fragmentos são recuperados de acordo com um ou mais critério de adaptação, ou requisitos para o processo adaptado, e são priorizados de acordo com fatores de contextualização de projetos de software definidos no Octopus Model. A técnica usada para esta priorização é Analytic Hierarchy Process (AHP), para guiar os engenheiros de processo na escolha dos melhores fragmentos para serem incluídos no processo de software padrão da organização (PSPO), dando origem ao processo adaptado, específico para o projeto. Um metamodelo foi proposto para a definição de fragmentos de métodos para serem utilizados na abordagem. Foi desenvolvida uma ferramenta para apoiar a abordagem proposta. Estudos de caso considerando riscos do projeto como critério de adaptação foram elaborados para validar a abordagem.

Capability is a long-established term and concept that has found its way to be used to describe organisations. It provides the basis for a genre of analysis, design and planning methods used in several fields. In enterprise architecture  frameworks, capability has become a central architectural and fundamental element. In the field of strategic management, it was used in the 1990s to describe the resources and core competencies that a company needs in order to compete in a market, while in military applications, the concept of capability is used for mission planning. It has also been suggested that the design of information systems could be based on the concept of capability. There is no broad agreement on the nature of capability in the enterprise architecture, strategy, planning and engineering literature. This may lead to problems, as differences in perception and use in and across work practices may hamper the utility of the concept of capability in practical approaches encompassing many different kinds of stakeholders, perspectives and work practices. The overall research goal of this thesis is to design a general concept of capability, a capability viewpoint and a capability situating method that can be used to adapt the concept of capability for use within enterprise architecture frameworks, to support different work practices, and at the same time to support coherence between work practices. The research methodology used in this thesis is based on the design science paradigm, which has the primary aim of creating innovative artifacts and new knowledge to solve general and practical problems. The thesis contributes to a deepened understanding of the varying uses and utility of the concept of capability in different work practices, through an empirical case study of a mega-scale programme. This work also presents three novel artifacts, a general capability pattern, a base capability viewpoint and a capability situating method, which can be used to increase the relevance, use and utility of the concept of capability in the different types of work people do themselves and together with others in organisations. The method provides a way to adapt and tailor the concept of capability to existing enterprise architecture frameworks and to different work practices, in order to lower the barriers of application, and to improve the facilitating conditions for and actual use of capability analysis, design and planning. The results contribute to the field of enterprise architecture by enabling the creation of ISO 42010 compliant situated capability viewpoints through the application of this method.

[EN] Software development projects are diverse in nature. For this reason, software companies are often forced to define their methods in-house. In order to define methods efficiently and effectively, software companies require systematic solutions that are built upon sound methodical foundations. Providing these solutions is the main goal of the Method Engineering discipline. Method Engineering is the discipline to design, construct, and adapt methods, techniques, and tools for the development of information systems. Over the last two decades, a lot of research work has been performed in this area. However, despite its potential benefits, Method Engineering is not widely used in industrial settings. Some of the causes of this reality are the high theoretical complexity of Method Engineering and the lack of adequate software support. In this thesis, we aim to mitigate some of the problems that affect Method Engineering by providing a novel methodological approach that is built upon Model-Driven Engineering (MDE) foundations. The use of MDE enables a rise in abstraction, automation, and reuse that allows us to alleviate the complexity of our Method Engineering approach. Furthermore, by leveraging MDE techniques (such as metamodeling, model transformations, and models at runtime), our approach supports three phases of the Method Engineering lifecycle: design, implementation, and execution. This is unlike traditional Method Engineering approaches, which, in general, only support one of these phases. In order to provide software support for our proposal, we developed a Computer-Aided Method Engineering (CAME) environment that is called MOSKitt4ME. To ensure that MOSKitt4ME offered the necessary functionality, we identified a set of functional requirements prior to developing the tool. Then, after these requirements were identified, we defined the architecture of our CAME environment, and, finally, we implemented the architecture in the context of Eclipse. The thesis work was evaluated by means of a study that involved the participation of end users. In this study, MOSKitt4ME was assessed by means of the Technology Acceptance Model (TAM) and the Think Aloud method. While the TAM allowed us to measure usefulness and ease of use in a subjective manner, the Think Aloud method allowed us to analyze these measures objectively. Overall, the results were favorable. MOSKitt4ME was highly rated in perceived usefulness and ease of use; we also obtained positive results with respect to the users' actual performance and the difficulty experienced. / [ES] Los proyectos de desarrollo de software son diversos por naturaleza. Por este motivo, las compañías de software se ven forzadas frecuentemente a definir sus métodos de manera interna. Para poder definir métodos de forma efectiva y eficiente, las compañías necesitan soluciones sistemáticas que estén definidas sobre unos fundamentos metodológicos sólidos. Proporcionar estas soluciones es el principal objetivo de la Ingeniería de Métodos. La Ingeniería de Métodos es la disciplina que aborda el diseño, la construcción y la adaptación de métodos, técnicas y herramientas para el desarrollo de sistemas de información. Durante las dos últimas décadas, se ha llevado a cabo mucho trabajo de investigación en esta área. Sin embargo, pese a sus potenciales beneficios, la Ingeniería de Métodos no se aplica ampliamente en contextos industriales. Algunas de las principales causas de esta situación son la alta complejidad teórica de la Ingeniería de Métodos y la falta de un apropiado soporte software. En esta tesis, pretendemos mitigar algunos de los problemas que afectan a la Ingeniería de Métodos proporcionando una propuesta metodológica innovadora que está basada en la Ingeniería Dirigida por Modelos (MDE). El uso de MDE permite elevar el nivel de abstracción, automatización y reuso, lo que posibilita una reducción de la complejidad de nuestra propuesta. Además, aprovechando técnicas de MDE (como por ejemplo el metamodelado, las transformaciones de modelos y los modelos en tiempo de ejecución), nuestra aproximación da soporte a tres fases del ciclo de vida de la Ingeniería de Métodos: diseño, implementación y ejecución. Esto es a diferencia de las propuestas existentes, las cuales, por lo general, sólo dan soporte a una de estas fases. Con el objetivo de proporcionar soporte software para nuestra propuesta, implementamos una herramienta CAME (Computer-Aided Method Engineering) llamada MOSKitt4ME. Para garantizar que MOSKitt4ME proporcionaba la funcionalidad necesaria, definimos un conjunto de requisitos funcionales como paso previo al desarrollo de la herramienta. Tras la definción de estos requisitos, definimos la arquitectura de la herramienta CAME y, finalmente, implementamos la arquitectura en el contexto de Eclipse. El trabajo desarrollado en esta tesis se evaluó por medio de un estudio donde participaron usuarios finales. En este estudio, MOSKitt4ME se evaluó por medio del Technology Acceptance Model (TAM) y del método Think Aloud. Mientras que el TAM permitió medir utilidad y facilidad de uso de forma subjetiva, el método Think Aloud permitió analizar estas medidas objetivamente. En general, los resultados obtenidos fueron favorables. MOSKitt4ME fue valorado de forma positiva en cuanto a utilidad y facilidad de uso percibida; además, obtuvimos resultados positivos en cuanto al rendimiento objetivo de los usuarios y la dificultad experimentada. / [CA] Els projectes de desenvolupament de programari són diversos per naturalesa.

Proporcionar aquestes solucions és el principal objectiu de l'Enginyeria de Mètodes. L'Enginyeria de Mètodes és la disciplina que aborda el diseny, la construcció i l'adaptació de mètodes, tècniques i eines per al desenvolupament de sistemes d'informació. Durant les dues últimes dècades, s'ha dut a terme molt de treball de recerca en aquesta àrea. No obstant, malgrat els seus potencials beneficis, l'Enginyeria de Mètodes no s'aplica àmpliament en contextes industrials.

Açò és a diferència de les propostes existents, les quals, en general, només suporten una d'aquestes fases. Amb l'objectiu de proporcionar suport de programari per a la nostra proposta, implementàrem una eina CAME (Computer-Aided Method Engineering) anomenada MOSKitt4ME. Per garantir que MOSKitt4ME oferia la funcionalitat necessària, definírem un conjunt de requisits funcionals com a pas previ al desenvolupament de l'eina. Després de la definició d'aquests requisits, definírem la arquitectura de l'eina CAME i, finalment, implementàrem l'arquitectura en el contexte d'Eclipse.

En aquest estudi, MOSKitt4ME es va avaluar per mitjà del Technology Acceptance Model (TAM) i el mètode Think Aloud.

En general, els resultats obtinguts van ser favorables. MOSKitt4ME va ser valorat de forma positiva pel que fa a utilitat i facilitat d'ús percebuda; a més a més, vam obtenir resultats positius pel que fa al rendiment objectiu dels usuaris i a la dificultat experimentada. / Cervera Úbeda, M.
