Concept of Government Enterprise Architecture for Czech Public Administration
Hrabě, Pavel ; Basl, Josef (advisor) ; Skrbek, Jan (referee) ; Čapek, Jan (referee)
The subject of the dissertation is exploring the use of enterprise architecture as a managerial method to support the transformation (reform) of Czech public administration. The dissertation shows that enterprise architecture is in the public sector of Czech Republic still not used, even though public sector organizations want to continue improving its services and management in a way where enterprise architecture could be beneficial. The thesis aims to understand the needs of public authorities towards the possibilities and benefits of enterprise architecture and propose such a customization that could increase the adoption and use of enterprise architecture by these organizations. The main objective of thesis is to summarize individual partial results of author's research into the design of overall Concept of the structure and procedure of implementation of National Public Administration Architecture of Czech Republic. Research within the dissertation combines two basic research methods. Both represent qualitative research methods, suitable for the development of new methods and artefacts (Design Science Research) and for proof the hypotheses and outputs (Case Studies). To create preconditions of the proposed concept was necessary to verify the status of the Czech public administration from the perspective of current rate, needs and interest for the use of enterprise architecture to support the reform of public administration. To verify the status of environment and the needs served basic research questions, further elaborated into detailed questions of multiple case study. In the analytical part of the thesis are summarized significant findings the analysis of information resources and literature in the areas of a) the definition of enterprise architecture, its position, role and development trends for design changes in the structure and metamodel of TOGAF framework, b) the existence of available models and key design principles of application architecture reference model and c) experience of the implementation and use of enterprise architecture for public administration reform. The main part of the thesis focuses on the proposals in three areas. In the first part are designed theoretical and practical changes in the definition, structure and metamodel of enterprise architecture to better support its application for real reform of public administration, not only to improve the management of IT. Presented proposals are in the same time providing solutions to some identified discrepancies in the trends of development of enterprise architecture. General proposals are in parallel applied as changes in the standard TOGAF, which is then recommended as the initial framework for the National Public Administration Architecture of the Czech Republic. In the second part of the proposals are presented principles and content of the reference model of application architecture. This is an example the accelerator necessary to solve the discrepancy between the scope of enterprise architecture and its feasibility with limited resources. The thesis emphasize the industry adjusted model for public administration and its application in a hierarchical, fractal environments typical of public administration. In the third part are presented key components of the overall concept, using as well as previous research results of this thesis. As the key elements are presented proposal for the structure of National Public Administration Architecture of the Czech Republic environment, proposal for the procedure of implementation of National Architecture and the proposal of products (outputs) for deploying National Architecture in Czech Republic. Additionally are formulated proposals of ways of using National Architecture in Czech public administration and conditions and prerequisites for introduction of National Architecture in the Czech public administration.

Enterprise Architecture as a Service
Gála, Libor ; Jandoš, Jaroslav (advisor) ; Zuzák, František (referee) ; Havlíček, Zdeněk (referee)
Although architectural services have been for a long time a common part of civil engineering, they are very rarely mentioned in theory and practice of enterprise architecture. Author of this thesis deals with formulation of the model of enterprise architecture as a service and its solution. The model is defined by a set of constructs and assumptions, which take into account current knowledge in the fields of enterprise architecture and services. In model solution a set of architectural services, which provide Enterprise Architecture agile and flexibly, is identified and defined. Validity of the model and of its solution is practically verified in two real-world cases: in a shared services center and in an external service provider.

Information model implementation in systems architecture
Pořádek, Jiří ; Říhová, Zora (advisor) ; Tumová, Jindra (referee)
This thesis deals with a field of information modeling and its relation to systems architecture. It is divided into two notional parts -- theoretical (first and second chapter) and practical (third and fourth chapter). First chapter explains the meaning of the term 'information model', compares it to the term 'data model' and then introduce its practical use in an enterprise modeling. It also defines the term of 'systems architecture' in its broad meaning and reduces it to three narrow meaning -- enterprise architecture, information architecture and information systems architecture, while it explains their relation to the information modeling. Finally this chapter provides the base for information model implementation methodology created later in the practical part of this thesis. Second chapter introduces architecture framework called TM Forum Frameworx specialized for a telecommunication services provider. It consists of three standards for business process, information and application architecture. The second one defines specific information model which is described partly in the second chapter and partly in the appendix B of this thesis. Third chapter describes the first of two contributions of this thesis - the information model implementation methodology. This methodology is applicable to any implementation of an information model. Three sections of this chapter contains diagrams and description of three phases of the methodology - pre-implementation phase, implementation phase and post-implementation phase. In the end of the chapter there is a table containing outputs of every single activity performed during all the phases. Fourth and last chapter then describes and evaluates real implementation of the information model from TM Forum Frameworx in the systems architecture department of an enterprise providing telecommunication services. This implementation based on the created methodology and its successful results then became the second contribution of this thesis.

Analysis and optimisation design of information system
Plojhar, Jan ; Vencovský, Filip (advisor) ; Voříšek, Jiří (referee)
This thesis is focused on information systems from the point of view of enterprise architecture. The theoretical part contains definitions and description of the key domains that are essential to understand for analysis and design of information system, which is in the practical part of the thesis. In this thesis in particular, the design of information system is about optimization of information systems of two petrol station branches that are part of OMV business network. This is done due to reduction of operation costs. After clarification of necessary concepts, three enterprise architecture frameworks are chosen and compared based on several criteria in the terms of their suitable utilization in the selected petrol stations. Then analysis of the problematic parts of information system is made according to the selected framework. Afterwards a design of information system is made according to the operator's requirements, owner's limitations and selected framework. The conclusion encompasses efficiency evaluation of the solution and its possible usage on different scope levels.

Designing integrated information system for product portfolio management support
Šebelík, Ondřej ; Koliš, Karel (advisor) ; Švecová, Lenka (referee)
Information is the currency of our world. Making right decisions requires having reliable, comprehensive and thorough information still at hand. The tools that can provide it? Information systems. However, the purpose of today's information systems is more than to just collect and store information: they need to integrate numerous data sources (both internal and external), identify essential pieces of information and set them apart from the rest, and provide the people relying on them a clear picture of the situation. In short: they should offer unified, user-friendly, well-structured and comprehensive view of business reality. This paper focuses on the first stage of an information system design. Concerned primarily with the business analytical phases of an IT project, it presents an insight into the process of business reality exploration and description through conceptual data model and architecture vision articulation.

Cooperation model for architecture and integration areas
Rubeš, Milan ; Jandoš, Jaroslav (advisor) ; Havlíček, Zdeněk (referee) ; Zuzák, František (referee)
In today's economics, medium and large-size companies are trying to gain a competitive advantage from specialization and centralization of supporting services. This trend affects also areas of enterprise architecture and integration where they establish particular teams to support the disciplines in regular manner. Despite a lot of research activities oriented towards these topics, there are only a few focusing on organizational aspects and cooperation between enterprise architecture and integration teams. As the companies are on different levels of the maturity in both areas and focusing on different aspects of architecture and integration, there is no simple solution that could provide detailed guidelines for establishing the right cooperation approach. Goal of this dissertation is to propose a cooperation model for architecture and integration teams that should make cooperation between such teams more efficient. Integral part of the dissertation is to verify the model in real environment. The model is built on top of integration activities performed either in enterprise architecture or integration teams or both. These activities are categorized into particular integration areas and relations are identified between integration areas and architecture areas defined according to TOGAF architecture framework. The resulting model is then being used to depict various kind of cooperation between architecture and integration teams based on the companys' integration goals. Verification of the model is performed in financial enterprise in two cases and confirms the benefits of the model.
