Comparé aux services traditionnels du secteur tertiaire, les services facilités par les technologies de l'information et des communications (ITeS, à partir du sigle en anglais, IT-enabled Services) suscitent un intérêt croissant de clients et fournisseurs d'une part du fait de l’automatisation des processus et d'autre part grâce aux nouveaux canaux de communication (Internet, réseaux mobiles, …) que ces services supportent. De ce fait, les ITeS co-créent de la valeur ajoutée due à la collaboration entre les clients et les fournisseurs lors de la conception et la livraison de services. Cet enrichissement des services traditionnels conduit à une remise à plat des méthodes actuelles de conception de biens et de services. En effet, elles ne permettent pas de répondre aux exigences imposées par ce contexte de collaboration multidisciplinaire qui intègrent les entreprises, les technologies de l'information et de la communication et les acteurs sociaux. Les caractéristiques intrinsèques des services (à savoir, l'intangibilité, l'inséparabilité, la périssabilité, la simultanéité) et leur nature sociotechnique requière à la fois une méthodologie de conception globale dirigée par les exigences des clients en vue de leur satisfaction et une approche systémique prenant en compte la dimension collaborative, le cycle de vie des services et les changements organisationnels, métiers et technologiques. Pour faire face à ces enjeux, nous proposons une méthodologie descendante pour modéliser et concevoir un système de services dirigé par les exigences des clients et supportant la collaboration entre tous les acteurs afin de permettre la co-création de ce système. Notre méthodologie repose sur une approche pluridisciplinaire et offre un ensemble de modèles interconnectés (modèle de référence de service, modèle d’exigence et modèle de collaboration) ce qui permet d’une part de donner de la flexibilité au système et de la rendre adaptable en cas de changements des exigences et d’autre part de supporter la collaboration entre tous les acteurs. Le modèle de référence offre une description des différentes dimensions du système de services (ontologique, caractéristiques et systémique) et explicite ainsi les connaissances liées aux domaines différents. En se basant sur le modèle d’exigences, les besoins du client sont spécifiés dans un langage commun et compréhensible par tous les acteurs. Ceci permet leur propagation dans tout le cycle de vie de service et leur diffusion à tous les acteurs. Le modèle de collaboration préconise une approche guidée par les données - une approche opposée aux processus métiers collaboratifs traditionnels - ce qui favorise l'interopérabilité technique et sémantique et augmente la stabilité du système face aux changements. Enfin, La collaboration s’appuie sur les canaux de communication qui engendrent des flux d'objets métiers selon lesquels des règles d'affaires sont générées afin d’invoquer les composants logiciels sous-jacents. / Compared to traditional business services, IT-enabled services provide more value to customers and providers by enabling traditional business services with Information and Communication Technologies (ICT) and delivering them via e-channels (i.e., Internet, Mobile networks). Although IT-enabled service systems help in co-creating value through collaboration with customers during service design and delivery, they raise challenges when we attempt to understand, design and produce innovative and intelligent IT-enabled services from a multi-disciplinary perspective by including businesses, technology and people for value addition and increasing benefits. Due to their social-technical nature and characteristics (i.e., Intangibility, Inseparability, Perishability, Simultaneity), IT-enabled services also lack common methods to systemize services driven by customer requirements and their satisfactions and co-produce them through ad-hoc collaboration. In this thesis, we propose a middle-out methodology to model, design and systemize advanced IT-enabled service driven by customer requirements and collaboration among all actors to jointly co-create service systems. From a multi-disciplinary perspective, the methodology relies on a multi-view models including a service system reference model, a requirement model and a collaboration model to ensure system flexibility and adaptability to requirement changes and take into account joint efforts and collaboration of all service actors. The reference model aims at a multi-disciplinary description of services (ontological, systematical and characteristic-based descriptions), and formalizing business knowledge related to different domains. As for the requirement model, customer needs are specified in common expressiveness language understandable by all service actors and made possible its top-down propagation throughout service lifecycle and among actors. The collaboration model advocates a data-driven approach, which increases busi-ness, technical and semantic interoperability and exhibits stability in comparison to business processes centric approaches. Finally, the collaboration hinges on de-livery channels expressed as data flows and encapsulating business artifacts as per which business rules are generated to invoke underlying software components.

Web applications provide the information technology (IT) implementation of business and align IT with business. Retirement of IT applications should ensure stability of business and IT alignment. The current study investigated the alignment gaps created between business and IT resulting from retiring IT software applications. The purpose of this study was to identify IT integration points with business and provide a process-based solution that sustained IT alignment with business after retiring IT applications. The theoretical framework strategic alignment model aided in identifying 3 IT domains as the IT integration points with business: enterprise architecture, configuration management database, and service-level agreement. The research methodology was grounded theory method. A process-in-operation facilitating application retirement generated the data. The grounded theory approach revealed the core category as IT and business alignment and established that the identified IT domains enabled IT alignment with business. The research findings revealed that structured decommissioning, timely repository updates, and 2-way communication between IT and business ensured continued accuracy and reliability of the repositories so business made valid interpretations. The findings may enable employees to realize their self-worth and dignity, leading to increased collaboration and coordination. The positive social change implications of these findings are in the increased alignment between IT and business, resulting in improved overall employee performance.

En systemarkitekts praktik består till stor del av att tolka, beskriva och strukturera verksamhetsprocesser och -information som underlag för förändrings- och utvecklingsarbete, oftast med stöd av it-system. Professionen betraktas traditionellt som en teknisk ingenjörskonst. Men de problem jag ställs inför som arkitekt handlar inte enbart om att designa tekniska system och kommunikation mellan maskiner, utan minst lika ofta om att hantera utmaningar relaterade till mellanmänsklig kommunikation i komplexa situationer. Vad händer om vi fokuserar på denna andra del av arkitektens praktiska kunskap? Denna magister- uppsats handlar om språkets och kommunikationens roll i kontexten av ett systemutvecklingsprojekt. Författaren använder sig av metaforer i en gestaltande skönlitterär kontext som kreativ metod för att visualisera och förmedla olika aspekter på systemarkitektens yrkesroll och praktik. På så vis utnyttjar uppsatsen den mer experimentella form som essän erbjuder för att även utforska sina egna uttrycksmöjligheter. Essäns teoretiska material baserar sig på den språkfilosofiska tradition som utvecklats av Ludwig Wittgenstein och Gilbert Ryle. Utifrån dessa båda tänkares verk förs ett resonemang runt språkets och den kontextuella förståelsens betydelse för systemarkitektens praktiska kunskap. Essän väver även in tankegångar från Thomas Kuhn, Peter Naur och Donald Schön i syfte att utforska just metaforens, improvisationens och den kreativa kommunikationens roll som verktyg i systemarkitektens praktik. / The system architect ́s practice is mainly about interpreting, describing and structuring the processes and information of an enterprise in order to create a foundation for change and development, often supported by IT systems. The profession is traditionally regarded as an art of technical engineering. But the problems I face as architect is not exclusively about designing technical systems and communication between machines, but just as much about handling challenges related to inter-subjective communi- cation between human beings in situations of complex interaction. What happens if we focus on this second aspect of the practical knowledge of the architect? This essay is about the role of language and communication in the context of a system development project. The author uses metaphors in fictional context as a creative method to visualize and mediate different aspects on the architect ́s professional role and practice. In that sense the text utilizes the more experimental form offered by the essay in order to explore its own expressive possibilities. The theoretical material of this essay is based on the language philosophical tradition developed by Ludwig Wittgenstein and Gilbert Ryle. Starting out from these two thinkers, the author reasons around the importance language and contextual understanding has for the practical knowledge of the system architect. Further on the essay weaves in thoughts from Thomas Kuhn, Peter Naur and Donald Schön with the purpose of exploring the role of the metaphor, improvisation and creative communication as tools in the practice of the system architect.

This dissertation focuses on the re-use of business process reference models, available in a business process model warehouse, to enable the definition of more comprehensive business requirements. It proposes a business process model warehouse framework to promote the re-use of multiple business process reference models and the flexible visualisation of business process models. The critical success factor for such a framework is that it should contribute to minimise to some extent the causes of inadequate business requirements. The proposed framework is based on an analogy with a data warehouse framework, consisting of the following components: usage of multiple business process reference models as source models, the conceptual design of a process to extract, load and transform multiple business process reference models into a repository, a description of repository functionality for managing enterprise architecture artefacts, and motivation of flexible visualisation of business process models to ensure more comprehensive business requirements. / Computer Science (School of Computing) / M.Sc.

Knowledge and knowledge work are key factors of today’s successful companies. This study devises an approach for increasing the performance of knowledge work by shifting it towards a process orientation. Business process management and workflow management are methods for structured and predefined work but are not flexible enough to support knowledge work in a comprehensive way. Case-based reasoning (CBR) uses the knowledge of previously experienced cases in order to propose a solution to a problem. CBR can be used to retrieve, reuse, revise, retain and store functional and process knowledge. The aim of the research was to develop an approach that combines CBR and process execution to improve knowledge work. The research goals are: a casedescription for knowledge work that can be integrated into a process execution system and that contains both functional and process knowledge; a similarity algorithm for the retrieval of functional and procedural knowledge; and an adaptation mechanism that deals with the different granularities of solution parts. This thesis contains a profound literature framework and follows a design science research (DSR) strategy. During the awareness phase of the design science research process, an application scenario was acquired using the case study research method, which is the admission process for a study programme at a university. This application scenario is used to introduce and showcase the combined CBR and process execution approach called ICEBERG-PE, which consists of a case model and CBR services. The approach is implemented as a prototype and can be instantiated using the ICEBERG-PE procedure model, a specific procedure model for ontology-based, CBR projects. The ICEBERG-PE prototype has been evaluated using triangulated evaluation data and different evaluation settings to confirm that the approach is transferable to other contexts. Finally, this thesis concludes with potential recommendations for future research. / Computing / D. Phil. (Information Systems)

Thesis submitted in fulfilment of the requirements for the degree Master of Technology: Information Technology in the Faculty of Informatics and Design at the Cape Peninsula University of Technology, 2012 / The purpose of this research is to investigate Enterprise Architecture (EA) strategies, and experiences with EA in the Provincial Government of the Western Cape (PGWC). This research examines the organizational and individual impacts as well as the organizational and technological challenges associated with implementing EA. The principles of EA are conceptualised and mapped in a structured manner to obtain a means to assess the EA experiences of the PGWC. The problem statement is: The efforts to implement Enterprise Architecture in the Provincial Government of the Western Cape have not delivered the desired benefits. This leads to the following objectives namely:  To establish an understanding of EA concepts and the basis for these concepts.  To investigate the current deployment status of the PGWC IT and business strategies.  To identify the stakeholders involved in EA deployment and how they participate in the deployment process.  To develop and propose a suitable framework for EA strategy deployment for PGWC. The main research question for this study is: How can enterprise architecture be deployed in PGWC in order to deliver EA benefits (of reducing redundancy, achieving alignment between business and IT, minimising costs) to PGWC? The main research sub-questions for this study are namely:  How did PGWC choose EA frameworks for their EA strategies?  How do PGWC deploy the chosen frameworks within the organisation?  What steps could be taken in order to deliver the benefits of EA at PGWC? The research philosophy is an interpretive qualitative approach. The methods for this research were an in-depth literature review, interviews with key role players, and questionnaires that gained information from a wider set of respondents. The aim of this study was to understand and explain the problems of implementing EA in PGWC. A guideline and an EA framework are proposed for organizations to assist in the deployment of an EA strategy.

eFörvaltning ses som ett medel för att göra kommunalt förvaltningsarbete mer effektivt och interoperabelt. Dock begränsas kommuner av oförmåga att uppnå det vilket försvårar genomförandet av deras uppdrag. En orsak till varför införandet av eFörvaltning inte ger de systematiska fördelar som efterfrågas beror på att införandet av informations och kommunikations teknologier (IKT) inte är tillräckligt. Förändringen som krävs kan inte ske över en natt utan är en gradvis förändring över tid som även kräver nya sätt att arbeta på. Kommuner behöver hantera sin eFörvaltningsutveckling på ett mer strukturerat sätt för att öka möjligheterna att förverkliga de fördelarna som sägs kunna erhållas. Enterprise Architecture (EA) har på senare tid kommit att ses som en möjlig lösning för att komma tillrätta med denna problematik. Genom att arbeta mot en EA skapas möjligheten att brygga IKT system med affärsprocesser och därigenom leda till effektivitet och interoperabilitet. Dock är EA inom offentlig sektor ifrågasatt. Forskare menar att EA saknar tydlig definierad omfattning och begreppsvärld, vilket gör användningen av EA inom förvaltningsarbete svår. De omfattande logiska EA ramverk som finns idag saknar innehåll som är specifikt relaterade till offentlig sektor. Vari det blir problematiskt att arbeta mot en EA inom offentlig sektor. Denna licentiatavhandling lägger följande forskningsfråga: ”Vilken roll har EA för införandet av eFörvaltning inom Svenska kommuner?” Samt följande underfrågor ”Vilka förutsättningar finns för att använda EA vid eFörvaltningsutveckling?” ”Vad har Örebro kommun uppnått genom att arbete mot en EA i deras eFörvaltningsutveckling?” Och ”Vilka problem har Örebro kommun upplevt av att arbeta mot en EA vid eFörvaltningsutvecklingen?”. En longitudinell fallstudie av ett eFörvaltningsutvecklingsprojekt i Örebrokommun genomfördes mellan 2007 och 2009 med syfte att utröna dessa frågor och för att skapa insikt om EAs roll för eFörvaltningsutveckling. Förutsättningar, resultat och upplevda problem vid eFörvaltningsutvecklingen studerades. I anslutning till detta empiriska arbete genomfördes även en jämförandestudie av eFörvaltningsmål såsom de anges i officiella statliga dokument inom så väl Sverige som i EU gentemot förmodade fördelarna med EA som diskuteras i samtida EA-litteratur. Studien visar att EA som fenomen ses som en förutsättning för att lyckas med eFörvaltning. 7 viktiga aspekter gällande förutsättningen för att lyckas med kommuners eFörvaltningsutveckling identifierades: Skillnaden mellan administrativa och politiska ansvaret, Politiskt mandat, Politisk timing, Resursfördelning, Samordning under NPM, Leverantörsberoende, Val av standard och bäst praxis. För att förbättra möjligheten att röna framgång i eFörvaltningsutveckling behöver dessa aspekter aktualiseras och hanteras. New Public Management (NPM) som styrmodell utgör ett strukturellt hinder för eFörvaltningsutveckling som förhindrar en mer explicit användning av EA-ramverk, vilket påverkar möjligheten att uppnå uppsatta mål negativt. Trots den strukturella problematik som föreligger, kan stöd erhållas genom att arbeta utifrån ett ”EA-tänk”. Ett ”EAtänk” kan här ses som ett medel för att påbörja förändringen mot en EA utan att för den delen explicit använda sig av ett EA-ramverk, eller -metod. Dock är det viktigt skapa en förståelse för att ”EA-tänk” som fenomen i sin tur ger upphov till strukturer och således kan leda till problem som även de måste hanteras för att eFörvaltningsutveckling skall lyckas. eFörvaltning, NPM och ett ”EA-tänk” skapar en strukturell triad där olika strukturella egenskaper i vissa fall sammanfaller med varandra vari de kan stödja kommuner i dess arbete och således bidra till positiv utveckling. Medan det i andra fall leder till negativ utveckling där administrationen upplever problem att ta till sig av de rekommendationer eFörvaltningsprojektet kan tänkas ge till organisationen som helhet. Paradoxalt nog skapar denna strukturella triad en situation där kommuner måste arbete runt sig själv för att komma framåt. Normer och befintliga strukturer i kommuner förhindrar effektiv samarbete både internt mellan olika förvaltningar och externt gentemot andra kommuner och landsting vilket leder till fragmentariska framsteg mot projektmålen och i slutänden även kommunens övergripande mål gällande eFörvaltningsutveckling. Givet de i många fall motstridiga strukturella egenskaper som finns mellan NPM och eFörvaltning innebär att det initiala arbetet mot EA i eFörvaltningsutveckling är ett ytterst komplext fenomen. För att öka möjligheten att eFörvaltningsutvecklingen blir lyckad krävs det att kommuner känner till och hantera den negativa inverkan NPM har på eFörvaltningsutveckling. Samtidigt behöver de känna till och hanterar problematiken som uppstår av att arbeta mot en EA genom ett ”EA-tänk”, Samt att som studien visat, EA ger inget stöd för mer politiseras mål, vari kommuner behöver annat sätt och andra strategier för sådant arbete. Detta är viktigt att beakta, speciellt med tanke på att mer politiserade mål i mångt och mycket är de mål som kommer premieras av politiker. Av just den enkla orsaken att politiker inte blir omvalda på grund av “effektiva IKT integrerade interna processer” utan blir omvalda utifrån förbättringar som är synliga och som gagnar medborgare positivt. Avhandlingen bidrar till forsknings genom att öka förståelse för och behovet av att hantera både positiva och negativa faktorer som påverkar möjligheten att lyckas med eFörvaltningsutveckling inom kommunalt arbete. Vilket inkluderar de 7 identifierade kritiska faktorer måste aktualiseras och hanteras för att öka möjligheten att lyckas. Den negativa effekt NPM har på eFörvaltningsutveckling och hur ett ”EA-tänk” kan leda till positiv utveckling, även om det som denna studie visat inte kan bidra till mer politiserade mål. Vad gäller denna licentiatavhandlings bidrag till praktiken så bidrar den med att belysa den problematiska situation som föreligger av att institutionaliserade strukturer i många fall verkar som ett hinder mot förändring. Studien möjliggör även till att kommuner kan skapa en förståelse för sin egna eFörvaltningsutveckling och möjligtvis kan verka för att inte uppleva samma problematik som identifierats i Örebros eFörvaltningsutveckling samt visa på hur en kommun kan arbeta för att hantera den problematik som inte kan förhindras alternativ som uppstår trots denna kunskap. / Governments struggle with inefficiencies and an inability to achieve interoperable information communication technology (ICT) systems. Apparent issues include a failure of local government to realize the benefits of electronic government (eGov) initiatives, high project failure rates, administrations hampered with inefficiencies, and a lack of interoperability between systems within the local government. Thus, local governments need to address their eGov initiatives in a structured way to improve their chances of providing the benefits that are sought after. Sweden’s eGov model is decentralized, following a strict new public management (NPM) model. Whilst eGov ought to bring benefits to local government, Sweden is still hampered by inefficiencies and an inability to achieve interoperable ICT systems. This has been the case for quite some time. One reason why systemic gains from adopting eGov have not reached the levels sought after could be that, in many cases, ICT implementations are not enough. The transformation needed for eGov is not instantaneous; it requires various new ways of working. Enterprise Architecture (EA) has come to be seen as a possible solution to the apparent issues of developing, adopting and managing eGov successfully. By utilizing EA, it is argued that it is possible to bridge ICT systems and business processes, thus making the organization more efficient. However EA’s usefulness for eGov development and adoption is the subject of debate. Some researchers argue that EA lacks clearly defined scopes and concepts, which makes the use of EA in government difficult. Whereas other argues that although EA frameworks are comprehensive logical frameworks, they lack content that is related specifically to government organizations. The thesis posits the following research questions: What is the role of EA in eGov adoption in Swedish local government? together with three sub questions: What are the prerequisites for using EA in Swedish local eGov adoption? What has the Swedish local government in Örebro achieved with its use of EA in eGov adoption? And What problems have the Swedish local government in Örebro experienced in its use of EA when adopting eGov? To explore the role of EA in eGov adoption a longitudinal case study is carried out on the municipality of Örebro’s eGov project MovIT, a project launched in 2007 that ended in 2009. I study the prerequisites, results and problems associated with using EA in Swedish local government as part of eGov adoption. A comparative study is conducted of the goals of eGov, as stated in official eGov documents at EU and Swedish governmental levels will attest as to the supposed benefits of EA in contemporary EA-literature. From the study, it can be concluded that EA, as a phenomenon, is thought to be, if not a silverbullet, then at least a prerequisite to eGov success. In term of prerequisites, EA use cannot assist Swedish local government where there are more politicized objectives; in this situation, local government is required to look elsewhere to find support for its work. The study identify several critical issues from the empirical study of the prerequisites: distinction between administrative and political responsibilities; political mandate; political timing; resource allocation; coordination under NPM; dependence on providers; and choosing among standards and best practices. These issues need to be acknowledged and handled appropriately by Swedish local government in order to improve the chances for success in eGov adoption. The study also showed that NPM as governance model becomes a hindrance in eGov adoption, preventing the project from a more explicit use of an EA-framework and negatively affecting the projects possibility to adopt eGov. However, despite this structural problem, it is still possible – as observed – for a project that is based on EA-thinking to begin working. EGov, NPM and EA-thinking form a triad, with structural properties that, in some instances, correlate. In such cases, this can lead to positive changes. However, in other situations, they are contradictory, resulting in Swedish local government having a difficult time in adhering to the suggestions endorsed by the eGov project. This lead to incoherent progressions towards requested results. The existing structures hindered effective cooperation, both internally between different departments and externally with other local governments. This licentiate thesis has shown that the initial use of EA in local government eGov adoption is complex. Given the contradictory nature of NPM and eGov, local government has to acknowledge the negative impacts of NPM on eGov adoption. As well as acknowledging the issues that arise from EA use, a key area is a lack of support of local government in an area that is most likely to be endorsed by politicians. Politicians do not get re-elected based on efficient internal processes with a highly integrated ICT; rather, changes must be visible to citizens and businesses. This licentiate thesis has also shown that ‘EA-thinking’, as a means for local government, can move towards an EA without the explicit use of an EA framework or EA method. However, ‘EA-thinking’ may give rise to other issues that need to be acknowledged and dealt with. This licentiate thesis contributes to research by improving our understanding of the nature and importance of promoting and inhibiting different factors. Including critical issues for succeeding with eGov adoption, the negative effects of NPM and how EA-thinking can lead to positive changes, even though it cannot assist local government in all aspects deemed important to eGov adoption. In terms of practice, this thesis contributes by highlighting the problematic nature of institutionalized structures and the effect that this has on eGov adoption. It also contributes by enabling local governments to acknowledge the problems identified. This allows them to better understand their own development and possibly avoid similar problems or at least have a better understanding of how to handle the issues that arise.

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.

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.
