Network documentation is often a low-priority task at many companies. Despite this, there are many benefits that should be considered against the fact that it is a comprehensive job. Good network documentation can provide companies the opportunity to reduce dependence on individuals, take proactive decisions and save money. Network documentation mainly consist of physical and/or logical topology descriptions that describes the logical and/or physical layout of the network. These so-called architectural views focus on technology rather than the services and features that the company's network provides. To simplify communication between stakeholders with different areas of knowledge, e.g. between an engineers and corporate management, I propose a model that complement traditional visual description of a network. With the help of viewpoint frameworks such as Kruchten's "4+1" model, I want to visualize relationships between corporate services, business processes, applications and the underlying infrastructure. A qualitative case study at a company with needs of network documentation has resulted in a prototype, a viewpoint framework, based on concepts of enterprise architecture. Analyzing a use case together with the prototype demonstrated that the prototype can visualize relationships between different layers in an organization. The prototype can be used as a starting point or guidance for those who want to document architecture of an enterprise network. The prototype can serve as means of communication in order to justify the investment that in turn ensures a modern energy-efficient operating environment that creates conditions for sustainable information- and communication technology. / Nätverksdokumentation är ofta lågt prioriterat på många företag idag. Men det finns många fördelar som borde vägas mot det faktum att det är ett omfattande jobb. Bra nätverksdokumentation kan ge företag möjligheten att minska personberoende, ta proaktiva beslut och spara pengar. Nätverksdokumentation består huvudsakligen av fysiska och/eller logiska topologidiagram, som beskriver nätverkets utformning. Dessa så kallade vyer fokuserar mer på teknik än de tjänster och funktioner som företagets nätverk tillhandahåller. För att förenkla kommunikation mellan olika intressenter med olika kunskapsbakgrund, t.ex. mellan ingenjörer och ledningen på ett företag, föreslår jag en modell som kompletterar den traditionella visuella beskrivningen av ett nätverk. Med hjälp av ramverk för vyer som t.ex. Kruchtens "4+1" modell, vill jag synliggöra samband mellan företagets tjänster, affärsprocesser, applikationer och den underliggande infrastrukturen. En kvalitativ fallstudie hos ett företag med behov av nätverksdokumentation har resulterat i en prototyp, ett ramverk för vyer, som bygger på koncept inom verksamhetsarkitektur. Analys av ett användarfall med prototypen som underlag demonstrerade att modellen kan synliggöra samband mellan olika skikt i en organisation. Prototypen kan användas som utgångspunkt för den som vill dokumentera arkitekturen hos ett företagsnätverk. Min modell kan fungera som ett kommunikationsmedel för att kunna motivera investeringar i nätverket, som i sin tur säkerställer en modern driftmiljö som skapar förutsättningar för hållbar informations- och kommunikationsteknik.

Information Technology (IT) has evolved over the decades, where its role and impact have transitioned from being a tactical tool to a more strategic one for driving business strategies to transform organizations. The right alignment between IT strategy and business has become a compelling factor for Chief Information Officer (CIO)s where misalignment could lead to a degradation of organization performance and slow them down in the landscape of market competition. Enterprise Architecture (EA) in practice is one of the approaches where this alignment can be achieved. Through Enterprise Modeling (EM), EA supports all the stakeholders (Business and IT) of an organization to have a common understanding for communication of information, making decisions, and coordinating actions. EM results in EA models that are composed of enterprise components and relationships, that are stored in a repository. Over time, the repository grows as architects design new models or update existing models with complex structures. This opens up new avenues of research where the data can be used to provide intelligence. One such field is Recommender Systems (RS) which are software tools and techniques to provide meaningful suggestions to the user. RS can take different forms in the EM domain. For instance, identifying semantically similar components [8] or modeling assistance during the EM process [40]. Each form of recommendation can be enhanced with sophisticated recommendation models over time implemented in different technologies. We focus on the latter problem in this thesis where we implement a recommender framework that contains a robust architecture that easily integrates with different RS. We present the robustness and the ease of integration criteria for the framework. The framework is distributed as a plugin for Archi, a modeling toolkit used by Enterprise Architects to create EA models. / Information Technology (IT) har utvecklats under decennierna, där dess roll och inverkan har övergått från att vara ett taktiskt verktyg till ett mer strategiskt verktyg för att driva affärsstrategier för att transformera organisationer. Den rätta anpassningen mellan IT-strategin och verksamheten har blivit en övertygande faktor för Chief Information Officer (CIO):er där felanpassning kan leda till en försämring av organisationens prestanda och sakta ner dem i konkurrensen på marknaden. Enterprise Architecture (EA) är i praktiken ett av tillvägagångssätten där denna anpassning kan uppnås. Genom Enterprise Modeling (EM) stöder EA alla intressenter (Business och IT) i en organisation att ha en gemensam förståelse för kommunikation av information, fatta beslut och samordna åtgärder. EM resulterar i EA-modeller som är sammansatta av företagskomponenter och relationer, som lagras i ett arkiv. Med tiden växer förvaret i takt med att arkitekter designar nya modeller eller uppdaterar befintliga modeller med komplexa strukturer. Detta öppnar för nya forskningsvägar där data kan användas för att tillhandahålla intelligens. Ett sådant fält är Recommender Systems (RS) som är mjukvaruverktyg och tekniker för att ge meningsfulla förslag till användaren. RS kan ha olika former i EM-domänen. Till exempel identifiera semantiskt liknande komponenter [8] eller modelleringshjälp under EM-processen [40]. Varje form av rekommendation kan förbättras med sofistikerade rekommendationsmodeller över tid implementerade i olika teknologier. Vi fokuserar på det senare problemet i den här avhandlingen där vi implementerar ett recommender-ramverk som innehåller en robust arkitektur som enkelt integreras med olika RS. Vi presenterar robustheten och enkelheten i integrationskriterierna för ramverket. Ramverket distribueras som en plugin för Archi, en verktygssats för modellering som används av Enterprise Architects för att skapa EA-modeller.

This thesis deals with the topic of benefits and challenges of Enterprise Architecture (EA) use in organizations. The main objective of this thesis is the critical analysis of EA potential use in sample organization by examining its benefits and challenges, which results in form of recommendations necessary for efficient management of the organization using EA. Firstly, the thesis introduces the topic of EA along with its core concepts and principles. Then, the author discusses main drivers for EA and its typical application. Perceived in the field of EA benefits and challenges are identified and classified. The result is then confronted with a practical case study, which describes EA application in a sample organization. The author conducts the experimental EA initiative in that organization, by modeling current state (as-is) and potential solution architectures. The main deliverable of this initiative for the organization is the critical analysis of potential EA use within the organization with the identification of its added value and challenges. The findings are then summarized in form of recommendations for the future development of information systems of the organization.

No. of bitstreams: 1 Romulo Arpini - Parte 1.pdf: 1684521 bytes, checksum: 258db1cddcd5120d8961c4a55aa1c741 (MD5) Previous issue date: 2012-08-31 / The need to relate the various architectural domains captured in partial descriptions of an enterprise is addressed in virtually all enterprise modeling approaches. One of these domains, namely that of organizational behavior, has received significant attention in recent years in the context of business process modeling and management. Another important domain, that of organizational structure is strongly inter-related with the process domain. While the process domain focuses on how the business process activities are structured and performed, the organizational structure domain focuses on who performs these activities, i.e., which kinds of entities in an organization are capable of performing work. Given the strong connection between the organizational behavior and organizational resources, we argue that any comprehensive enterprise modeling technique should explicitly establish the relations between the modeling elements that represent organizational behavior, called here behavioral elements, and those used to represent the organizational resources (organizational actors) involved in these activities, called here active structure elements. Despite the importance of the relations between these architectural domains, many of the current enterprise architecture and business process modeling approaches lack support for the expressiveness of a number of important active structure allocation scenarios. This work aims to overcome these limitations by proposing a framework for active structure assignment that can be applied to enterprise architecture and business process modeling approaches. This framework enriches the expressiveness of existing techniques and supports the definition of precise active structure assignments. It is designed such that it should be applicable to a number of enterprise architecture and business process modeling languages, i.e., one should be able to use and apply different (enterprise and business process) modeling languages to the framework with minor changes / A necessidade de se relacionar os vários domínios arquiteturais capturados em descrições parciais de uma organização é, virtualmente, tratado em todas as abordagens de modelagem de arquiteturas organizacionais. Um destes domínios, particularmente chamado de comportamento organizacional, tem recebido atenção significativa nos últimos anos no contexto de modelagem e gerenciamento de processos de negócio. Outro domínio importante, chamado de estrutura organizacional, é fortemente inter-relacionado com o domínio de processo. Enquanto o domínio de processo foca em "como" as atividades de processos de negócio são estruturadas e executadas, o domínio de estrutura organizacional foca em "quem" executa essas atividades, i.e., quais tipos de entidades em uma organização são capazes de executar trabalho. Dada a forte conexão entre o comportamento organizacional e os recursos organizacionais, nós argumentamos que qualquer técnica de modelagem de arquitetura organizacional deve explicitamente estabelecer relações entre os elementos de modelagem que representam o comportamento organizacional, chamado aqui de elementos comportamentais e aqueles suados para representar recursos organizacionais (atores organizacionais) envolvidos nestas atividades, chamados aqui de elementos da estrutura ativa. Apesar da importância das relações entre esses domínios arquiteturais, muitas das abordagens de modelagem de processo de negócio e modelagem de arquiteturas organizacionais tem um suporte insuficiente para expressar uma quantidade importante de cenários de alocação da estrutura ativa. Este trabalho visa superar essas limitações propondo um framework para a atribuição da estrutura ativa que pode ser aplicado a abordagens de modelagem de processo de negócio e modelagem de arquitetura organizacionais. Esse framework enriquece a expressividade das técnicas existentes e dá suporte à definição de atribuições precisas da estrutura ativa. Ele é desenvolvido tal que pode ser aplicável a linguagens de modelagem de processo de negócio e linguagens de modelagem de arquiteturas organizacionais, i.e., é possível utilizar e aplicar diferentes linguagens de modelagem ao framework com mudanças mínimas
