Tato diplomová práce se zabývá problematikou servisně orientované architektury a služeb, které tvoří její základní stavební prvky. Jejím cílem je vymezení způsobu, jakým lze navrhovat jednotlivé podnikové aktivity jako služby, které jsou založeny na podobném principu a disponují stejnými charakteristikami jako služby, které jsou navrhovány na technologické úrovni SOA. Práce je rozdělena do pěti částí. Smyslem prvních čtyřech je vytvoření určitého teoretického základu, který je následně využit pro účely prakticky orientovaného příkladu, který se zabývá identifikací služeb. První část je věnována vysvětlení podstaty a významu enterprise architektury. Na ní navazuje další část, která ze zabývá architektonickými frameworky a jejímž smyslem je popsání charakteristik frameworku NGOSS (New Generation Operations Systems and Software), který je určen pro poskytovatele telekomunikačních služeb. Nástroje tohoto frameworku, kterými jsou datový model eTOM (enhanced Telecom Operations Map) a datový model SID (Shared Information/Data Model) jsou využívány v již zmiňované závěrečné části. Předposlední část práce je věnována teoretickému pojednání o servisně orientované architektuře a službách. Kapitola obsahuje popis procesu zavádění servisně orientované architektury a dále uvádí charakteristiky, kterými by měli služby disponovat. Závěr práce je věnován názornému příkladu, jak přistupovat k identifikaci služeb. V rámci závěrečné části je jednak navrhován postup, jak služby identifikovat na základě podnikových procesů a jednak jsou zde demonstrovány a hodnoceny možnosti využití obou zmiňovaných nástrojů frameworku NGOSS v rámci tohoto postupu

This diploma thesis concerns Service-Oriented Architecture and possibilities of using framework NGOSS (New Generation Operations Systems and Software) by its adoption to organization. Diploma thesis is divided into four main parts. The first three parts are theoretical and are the foundation for the last practical part of diploma thesis. The first part is devoted to enterprise architecture and to their importance for a big company. The second part of the diploma thesis is devoted to framework, to their principles and importance in connection with enterprise architecture. In first chapters of this part is devoted to description of framework generally, while the last parts contain the description of particular framework for telecommunication industry named NGOSS. I describe its main characteristics and its main parts with emphasis on its part concerning architecture of information system named TNA (Technology Neutral Architecture). This TNA description also contains description of NGOSS contract, which is very important for practical part of diploma thesis. The third and the last theoretical part is concerned with service oriented architecture and its main architectural elements -- services. In the last and practical part of diploma thesis, I am trying to design NGOSS contract for the chosen SOA service and demonstrate its importance for SOA adoption. The end of the practical part contains conclusion on possibilities and benefits of NGOSS framework by SOA adoption.

Este trabalho apresenta um conjunto de conceitos, ferramentas e metodologias que, se aplicados em conjunto, permitem às entidades responsáveis por desenvolver e oferecer serviços de telecomunicações atender melhor às expectativas dos seus clientes. Esse conjunto de ferramentas foi criado a partir da identificação e seleção de conceitos e metodologias desenvolvidos originalmente para serem aplicados em diversas atividades: produção fabril, projeto de produtos para consumo massificado, gestão de redes de telecomunicações, gestão empresarial e outros. As ferramentas selecionadas incluem conceitos das áreas de Gestão da Qualidade Total, dos trabalhos do TeleManagement Forum e da Fundação Nacional da Qualidade. Os conceitos e metodologias selecionados foram então posicionados sobre um conjunto de mapas e diagramas que visam representar a interação entre consumidores, seus prestadores de serviço e as entidades que desenvolvem serviços para estes. Assim, este trabalho parte de uma ampla gama de conhecimentos originários de diversas disciplinas diferentes e propõe uma maneira de integrá-los de forma otimizada para aplicação em serviços de telecomunicações. / This work presents a set of concepts, tools and methodologies that, if applied together, allow telecommunications service providers and developers to better fulfill their customers\' expectations. This set of tools was created by identifying and selecting concepts and methodologies originally developed for deployment on different industries: manufacturing, consumer goods development, communications network management, corporate management and so on. The selected tools include concepts from Total Quality Management, the works of the TeleManagement Forum and the models developed by the Brazilian National Foundation for Quality (FNQ). These selected concepts and methodologies were then positioned over a set of conceptual maps and diagrams that aim to model the interaction between consumers, their service providers and the entities that develop services for the later. As such, this work starts from a broad range of techniques that come from very different knowledge fields and proposes a way to integrate them in an optimized set for application on the telecommunications industry.
