Today, the design of business enterprises is much more art than science. The complex structure and behavior of enterprises makes it difficult to untangle cause and effect amidst its components and their relationships. In order for managers to understand how an enterprise's architecture affects its behavior, they need tools and techniques to help them to manage the complexity of the enterprise. The practice of enterprise architecting continues to make advances in this area with reference frameworks that can be used to guide the decomposition and communication of enterprise architectures, but it does not provide tools to analyze the potential behavior of a proposed enterprise architecture. This research seeks to extend the practice of enterprise architecting by developing an approach for creating simulation models of enterprise architectures that can be used for analyzing the architectural factors affecting enterprise behavior and performance. This approach matches the content of each of the "views" of an enterprise architecture framework with a suitable simulation methodology such as discrete event modeling, agent based modeling, or system dynamics, and then integrates these individual simulations into a single hybrid simulation model. The resulting model is a powerful analysis tool that can be used for "what-if" behavioral analysis of enterprise architectures. This approach was applied to create a hybrid simulation model of the enterprise architecture of a real-world, large-scale aerospace enterprise.
(cont.) Simulation model analysis revealed potential misalignments between the current enterprise architecture and the established strategy of the enterprise. The simulation model was used to analyze enterprise behavior and suggest relatively minor changes to the enterprise architecture that could produce up to a 20% improvement in enterprise profitability without increasing resources to the enterprise.

Full textENGLISH ABSTRACT: Knowledge assets can be defined as anything that affects a business’s disposition to act on data received from the environment. Knowledge assets are embedded in the objects within an organisation and are the source of an organisation’s competitive advantage, by being closely linked to what the organisation knows and by allowing the organisation to act and to be innovative. Knowledge assets evolve over time as knowledge agents, through a process of sense making, substitute physical resources for informational resources by codifying and abstracting knowledge assets, in the process increasing their value and ability to be diffused to wider audiences. These knowledge assets are internalised in an organisation and impact on the organisation when they are applied to concrete problems. Knowledge assets play an important role in the creation of information assets in an organisation. Information assets are created when a knowledge agent makes use of his or her knowledge to make sense of data received from sources in the environment. The creation of information through the sense making process creates new knowledge which is added to the agent’s knowledge base. Enterprise architecture is the process of designing future states for an organisation and then planning, leading and governing the organisation towards that future state. Enterprise architecture focuses mostly on the organisational process, on information and technology. Enterprise architects make use of enterprise architecture frameworks such as TOGAF or the Zachman framework, which are primarily concerned with the domains of business, information and technology architecture, yet none of these mainstream frameworks used by enterprise architects takes knowledge assets into account, despite the obviously important role that they play in the organisation and especially in the information creation process. This research proposes to show that knowledge assets have an important role to play in enterprise architecture by allowing enterprise architects to • identify or facilitate the creation of knowledge assets pertaining to a specific problem; • understand whether information assets are located in the ordered and complex or the chaotic regimes and what would be the implication of moving them between regimes; • plot knowledge assets movements and relationships to each other on the social learning cycle path, which would enable enterprise architects to balance the types of learning that the organisation employs; • define the level of codification, abstraction and diffusion of knowledge assets, based on the intended audiences and to understand where knowledge assets could be developed to improve quality and when outdated knowledge should be destroyed in favour of new knowledge. Knowledge assets are related to Enterprise Business Architecture (EBA) through the specific knowledge domains that exist within an organisation. Understanding whether knowledge assets exist in the ordered, complex or chaotic regimes will provide a more complete view of the organisation. Architecture of knowledge assets in this space will provide a better understanding of an organisation’s culture: this understanding can compensate for differences in knowledge agents’ spatio-temporal positions, how and when they receive data and their particular cognitive styles. The importance of knowledge assets in the creation of information links it emphatically with Enterprise Information Architecture (EIA). Knowledge asset architecture provides a better understanding of how information is created and flows through an organisation, taking into account the meaning of the information to the organisation, which compensates for that oversight in information theory, which regards the accuracy of data that is communicated as the only concern. Information technology has exponentially increased mankind’s ability to codify, abstract and diffuse knowledge assets. Enterprise Technical Architecture (ETA) is mainly concerned with the technology infrastructure implemented within an organisation. Enterprise architects can apply knowledge asset architecture to decide whether the technology should be used to enhance the codification and abstraction of information, allowing more efficient diffusion of information to a larger audience, or whether more concrete information should be diffused to a more closely-knit audience. This research will argue that the use of knowledge assets as a domain within enterprise architecture will greatly enhance the enterprise architect’s ability to understand and lead the organisation to a more desirable future state.
AFRIKAANSE OPSOMMING: Kennisbates is vasgelê in die konkrete en abstrakte voorwerpe in die organisasie. Hierdie voorwerpe omsluit alle voorwerpe wat ‘n effek het op hoe die organisasie reageer op data wat vanaf die omgewing ontvang word. Kennisbates is ‘n bron vir die kompeterende voordeel wat ‘n organisasie geniet omdat dit verband hou met wat die organisasie weet en dit die organisasie in staat stel om te innoveer. Kennisbates sal aangaande evolueer soos wat kennisdraers, deur die sinmaak proses, fisiese hulpbronne vervang met inligtings hulpbronne gedurende die proses van kodifisering en abstraksie en sodoende die kennisbates se waarde vir die organisasie te verhoog en beskikbaar te stel vir groter gehore. Die kennisbates word dan vasgelê in die organisasie wanneer die kennis toegepas word op konkrete probleme. Kennisbates speel ‘n belangrike rol in die skepping van inligtingsbates in die organisasie. Inligting word slegs geskep wanneer die kennisdraer gebruik maak van sy kennis om sin te maak van data onvang vanuit die omgewing. Die nuwe inligting word dan intern vasgelê in die kennisdraer as nuwe kennis. Ondernemingsargitektuur is ‘n proses waardeur die toekomstige staat van ‘n organisasie ontwerp word deur beplanning, en daar verder leiding gegee word ter uitvoering daarvan. Ondernemingsargitektuur fokus meestal op die organisasie se prosesse, inligting en tegnologie. Ondernemingsargitekte maak gebruik van ondernemingsargitektuurraamwerke soos TOGAF en die Zachmanraamwerk as riglyne vir hulle werk. Hierdie raamwerke fokus primêr op die besigheid, inligting en tegniese domeine van argitektuur. Nie een van die hoofstroom ondernemingsargitektuurraamwerke neem kennisbates in ag nie, ten spyte van die voordiehandliggende belangrike rol wat kennisbates in die organisasie se inligtingskeppingsproses speel. Hierdie navorsing stel voor dat kennisbates deel kan vorm van ondernemingsargitektuur deur ondernemingsargitekte toe te laat om • kennisbates aangaande ‘n spesifieke probleem te identifiseer of die skepping daarvan die fasiliteer, • te bepaal of die kennisbates in die geordende, komplekse of chaotiese regime bestaan en wat die implikasie sou wees om hulle na ‘n ander regime te skuif, en • die kennisbates op die sosiale leersiklus aan te stip, wat die ondernemingsargitek in staat sal stel om die leerbenaderings van die organisasie te balanseer, die vlak van kodifisering, abstraksie en verspreiding te definieer, gebaseer op die voornemende gehoor vir die spesifieke inligting. • beter begrip te hê daarvoor of die kennisbate na ‘n beter kwaliteit ontwikkel moet word of vernietig moet word om plek te maak vir nuwe kennisbates. Daar bestaan ‘n verwantskap tussen OBA (Ondernemingsbesigheidsargitektuur) deur die spesifieke kennisdomein wat reeds in die organisasie bestaan. Deur te verstaan of die kennisbates binne die geordende, komplekse of chaotiese regimes val sal beter begrip bied van die organisasie as geheel. Al hierdie gesigshoeke word in die geordende domein beskryf. Kennisbateargitektuur sal ‘n beter begrip van die organisasie se kultuur bewerkstellig. Die kultuur in ‘n organisasie word gebruik om te vergoed vir die verskille in die kennisdraer se tyd-ruimtelike ligging tydens die ontvangs van data asook hulle kognitiewe styl. Daar bestaan ‘n daadwerklike verwantskap tussen kennisbateargitektuur en Ondernemingsinligtingsargitektuur (OIA). Kennisbateargitektuur sal bydra tot die begrip van hoe inligting geskep word en vloei deur die organisasie. Dit sal die betekenis van inligting in ag neem en daardeur vergoed vir die tekortkoming van inligtingteorie wat slegs die korrektheid van die data wat vervoer word in ag neem. Inligtingstegnologie het die mens se vermoë om inligting te kodifiseer, abstraksie toe te pas en te versprei eksponensieël verbeter. Ondernemingstegnieseargitektuur (OTA) is hoofsaaklik verantwoordelik vir die tegnologiese infrastruktuur wat geïmplimenteer word binne die organisasie. Ondernemingsargitekte kan kennisbates gebruik om te besluit of tegnologie gebruik moet word om beter inligting te skep deur hoër kodifisering en abstraksie toe te pas, om daardeur die vermoë te skep om die inligting vir ‘n wyer gehoor beskikbaar te stel, of om meer konkrete inligting vir ‘n meer intieme gehoor beskikbaar te stel. Hierdie navorsing stel voor dat kennisbates as ‘n domein binne die ondernemingsargitektuur vervat word. Dit sal die ondernemingsargitek in staat stel om die organisasie beter te lei na ‘n wenslike toekomstige staat.

Full textWith the introduction of networking into telemetry applications, these systems have become increasingly complex. This imposes significant strain on information security for architecture designs. It has been recognized that an organized or structured approach to developing security architectures is needed. Several enterprise architecture frameworks are available today that address system complexity. However they fall short of addressing security at a high enough level in the enterprise and address security too late in the design process. In this paper a methodology is proposed that bridges the gap between security requirements and architecture design development at the enterprise level. This approach is consistent with and traceable to the original needs of the customer. This paper introduces a systems engineering approach to develop an enterprise level methodology, and presents a worked example of this approach for the integrated Network Enhanced Telemetry system.

Full textEn vanlig utmaning inom organisationer är uppfattningen av att olika språka talas på IT-avdelningen och övriga avdelningar. Medarbetare kommer från olika bakgrund, har olika kunskapsbas och ibland till och med olika mål, vilket kan göra fastställandet av riktning mer utmanande. Enterprise Architecture (EA) kan säkerställa att IT investeringar och affärs direktiv går i samma riktning och kan därmed potentiellt lösa problem i anslutning till IT och övrig affärsverksamhet som uppstått på grund av detta och skapa värde till organisationen. Teknisk skuld är ett väletablerat koncept inom mjukvaruutveckling och syftar till att enlösning som är ”quick and dirty” tillämpas för att vinna tid på kort sikt och kunna tillämpa en funktionalitet i ett system snabbare. Denna primitiva implementation kommer vid senare tillfälle behöva korrigeras och skrivas om. Ju längre tid det tar desto mer avancerad, komplex och tidskrävande kommer ändringen att bli. I takt med att EA har vuxit har stora vetenskapliga och akademiska bidrag utvecklats. Vad som fortfarande saknas är insikt och förmåga att inkludera ett skuldkoncept som inte bara adresserar tekniks skuld utan även affärsaspekter. Genom att introducera konceptet teknisk skult i EA domänen har en ny metafor, som tillhandahåller ett helhetsperspektiv, föreslagits; Enterprise Architecture Debt (EA Debt). Fram tills idag har skulder för att mäta EA Debt blivit identifierade, men aktuella forskningsprojekt har ännu inte identifierat när en viss EA Debt är hög eller låg. Det finns ett behov av att utveckla en process för att härleda sådana gränsvärden och identifiera dem. För att kunna kommunicera all varlighetsgraden för en EA Debt till intressenter kan gränsvärden för EA Debt spela en viktig roll. Dessa gränsvärden kommer på lång sikt spela en roll när det kommer till att tillhandahålla verktyg för datavetare som arbetar i organisationer som tillämpar EA, och också bidra till aktuell forskning inom IT-förvaltning och EA. Genom att anta en systematisk process för att definiera expertdrivna gränsvärden har en första version av en process för att definiera EA Debt-gränsvärden kunnat presenteras och testas med domän-experter. Fem vanliga uppfattningar, gällande processen, kunde uppräckas bland experterna. Processens skulle också potentiellt kunna främja användbar kommunikation och det ansågs positivt att den belysta och tog hänsyn till kontext gällande EA Debt. Att tydligare processbeskrivning och verklighetstrogna EA-modeller som exempel behövdes samt att momentet där medlemsfunktion skulle väljas var onödigt kom också upp. Vidare så fokuserade studien på drivkrafter för att ta fram gränsvärden för EA Debt och områden där uppfattningen är att detta är viktigt. Kostnad och tid, ansvar och engagemang och kontext är uppfattade som viktiga drivkrafter när det kommer till gränsvärden för EA skuld, medan inriktningen för IT och övrig affärsverksamhet och basdata ses som viktiga områden. Även kontexten kan ha en viktig roll när det kommer till att avgöra vilka områden som är viktiga.

Full textSouth Africa has a complex financial and retail service industry with high reliance on the use of IT systems to ensure effectiveness and maintainability. Decision making and improved outcomes may be done through an IT aligned enterprise architecture (EA) strategy. EA is a capability that contributes to the support and success of an organisations' IT. Organisations are currently using EA to better align IT and the business strategy which provides a comprehensive v.ew of the IT system. Thus, EA is increasing in organisations yet the measurement and value of EA is limited to organisations and enterprise architects. The discussions of the benefits and value of EA has been discussed for several years, however there are still no consensus about how the benefits and value of EA can be measured. The lack and clear understanding of the benefits and value of EA needs to consider different aspects of IT as well as the shareholders when measuring the benefits and value of EA to an organisation.

This paper reports results of a study done to understand the Enterprise Architecture (EA) landscape in Singapore Government Agencies, to gather some best practices in doing EA in these agencies, and to postulate how the Singapore Government might get more value out of EA. Firstly, this paper reviews the EA field on why EA is important and what are some key challenges EA practitioners face. Secondly, this paper reviews and analyzes data from a EA survey of 18 Singapore Government Agencies. The analysis is done by comparing against data from a similar survey collected from over 100 organizations worldwide. In addition, the analysis also draws upon EA research done by MIT's Center for Information System Research. Thirdly, this paper reviews best practices and a case study collected from a subset of the studied Singapore Government Agencies. This paper concludes by rounding up the key findings and hypothesizing that there is a need for stronger inhouse design/architecting capabilities within the Singapore Government.

Belfadel, Abdelhadi. "Enterprise Architecture Capability Profile for Software Reuse." Thesis, Lyon, 2019. http://www.theses.fr/2019LYSE2125.
Full textMost of today's software development projects depend on the usage of existing solutions to save time and development cost. To achieve this goal, companies should take advantage of the features provided by services or application programming interfaces exposed by existing solutions. Collecting and qualifying IT components and services helps to reuse them directly or via orchestration. The goal of this work is twofold. First, we target the design of a software capability container that provides a broader view of an organization’s internal and external software. The second objective is to define an exploitation model of the software capability profiles in line with requirements engineering and enterprise architecture, to fill the gap between the goals of the stakeholders and what can be delivered as a practical solution. However, to achieve the above-stated objectives, there are many challenges to manage the complexity of the exploitation of internal or external’s software capability profiles, to select the best candidate components to act as a building blocks in a new system. Among those challenges, one can mention the identification of architectural artifacts for the evaluation and reuse of software components. Adding to this challenge, the alignment of requirements and architectural artifacts in engineering cycle for requirements consolidation and refinement to facilitate the discovery and reuse of existing solutions.For this purpose, we define a Framework offering a qualification process that helps to retrieve and gather initial requirements used to guide the development of existing software and related services. The qualification process is based on a proposed Enterprise Architecture Capability Profile and its associated ontology. This latter is useful to formally specify and encode the produced capability2profile that offers a qualification and covers business, operational and technical aspects for service-oriented software. Furthermore, an exploitation methodology of the designed container is proposed along with the Framework and based on the alignment of requirements engineering process with an architecture development method. These latter evolve together to investigate the highest functional and technical compatibility of the desired functionalities and related constraints, to respond to end-user’s requirements and efficiently reuse the qualified solutions.Our contribution aims to improve the evaluation, discovery, and reuse of existing software and related services. Besides, the originality of this research work consists in upgrading research on services consumption and orchestration to the level of end-users’ requirements, mapped with advanced service assets as an enabler for accelerating business application development. An implementation of the Framework along with an industrial case study are proposed to validate and demonstrate the effectiveness of this approach

Full textThe adoption of Enterprise Architecture (EA) methodologies within organizations is causing an interest in the methodologies and supporting technologies available. Service Oriented Architecture (SOA) supports EA in many facets. However, there is much suspension with regard to the relationship between EA and SOA within organizations as well as the guidelines that organisations should follow in order for SOA to enable EA. There are potential problems that may arise if this relationship between SOA and EA is not agreed to at the outset of implementing an EA. The purpose of this research is to investigate the guidelines that are needed for SOA to enable EA, in order to provide practical steps that organisations can use to begin aligning SOA and EA, ensuring that these initiatives are driven from a business perspective. A qualitative approach using a case study was used as a methodology for this research. The data collection was conducted using semi-structured interviews, and the guidelines that were derived were validated through a survey that was distributed to industry architecture practitioners. The contribution of this research was a set of guidelines that can be used for SOA to enable EA. Further research areas were highlighted, including investigating the mapping of the guidelines that were derived from this research, into the EA frameworks that exist such as TOGAF and ZACHMAN.

Full textThe 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.

Dålig kodkvalitet “code smell” är vanligt förekommande teknisk skuld. Det uppkommer i vanliga dåliga metoder “anti-patterns” som försämrar programvarans framtida kvalitet. För att kunna identifiera bristande kodkvalitet är det möjligt att skapa en förbättrad lösning eller göra utvecklare medvetna om de möjliga bristerna. Jag undersöker förutsättningarna att en sådan teknisk skuld i företag bör undersökas med en programvara. Utbyggbara och ändamålsenliga programvaror kan analysera källkod och hitta var kvaliteten behöver förbättras. Företagens tekniska skuld kan definieras som ett mått som visar avvikelsen från ett hypotetiskt idealtillstånd genom att jämföra det aktuella tillståndet med praktiska rekommendationer “best practice”. I detta examensarbete introducerar jag SmellCull som ett utbyggbart verktyg för att hitta, spåra och hantera bristfällig kodkvalitet inom företagsarkitektur (EA). SmellCull tillåter mätning av olika typer av tekiska skulder för EA modellen. SmellCull är utbyggbart genom att olika typer av datamodeller kan integreras som indata i miljön, och det ger utveck-lare ett lätt verktyg för att hantera teknisk skuld i programmeringsprojekt och hjälpa projektdeltagarna i programmeringsprojekt att förstå vad orsakar brister i kodkvalitet. Eftersom verktyget är tillräckligt sofistikerat finns det automatiserad spårning, designprocess och kontinuerlig förbättring av EAS (Enterprise Architecture System). Detta inkluderar strategisk utveckling av EAS med motsvarande färdplan, samt konstruktionssäkerhet och prestandäovervakning för att bedöma kvaliteten på data i EA förvar och efterlevnaden av vissa standarder som definieras av EA code smell detection. På grund av den begränsade omfattningen av examensarbetet kommer verktyget att identifiera några få EA skuld. I slutet, några framtida arbetsförslag i samband med identifiering mer säljbara företagsarkitekturskulder med detta verktyg ges.

Full textEnterprise architecture frameworks (EAFs) have been used to plan and manage large-scale enterprise deployments for more than four decades. EAFs are important tools used by systems engineers and are integral to characterize enterprise information architectures. They are increasingly being used as a proxy for managing entire organizations – enterprises. Enterprises represent complex, multi-disciplinary, socio-technical systems. They are ubiquitous, and involve and affect a vast number of humans every day. However, as inter-disciplinary tools for the management of the enterprise, there are certain limitations to the efficacy of existing enterprise architecture frameworks. The effective management of enterprises presents significant challenge and opportunity for the systems engineering community. This research discusses the limitations of, and proposes enhancements to, existing EAFs, based on research into extant business management frameworks. An historical perspective is provided on both systems engineering and business enterprise domain frameworks. Research into the common elements of successful business management frameworks confirms the limitations of existing systems engineering frameworks and suggests key additions for enhanced efficacy. The applicability and relevance of enhancing extant enterprise architectures with elements from extant business frameworks is examined. Finally, recommendations are made for enhancements to extant frameworks and suggestions advanced on future research into efficacy. This dissertation concludes with implications of these findings for systems engineers engaged in enterprise architecture and enterprise transformation efforts and a recommendation that systems engineers take a more holistic approach in their enterprise architecture and enterprise transformation efforts.

Full textO crescimento do tamanho, complexidade e demanda por qualidade dos sistemas de software são alguns dos motivos que tem aumentado o interesse na área de arquitetura de software. Consequentemente, processos de arquitetura de software surgiram a fim de auxiliar os arquitetos na construção dessas arquiteturas. Arquitetura Orientada a Serviços (SOA) surgiu como um tipo de arquitetura de software para construir sistemas através da composição de serviços. Assim como o paradigma de orientação a objetos, o paradigma de orientação a serviços tem trazido uma abordagem de projeto distinta que introduz princípios que governam o posicionamento e o projeto dos componentes arquiteturais. Além disso, SOA é um paradigma para organização e utilização de capacidades distribuídas que podem estar sob o controle de diferentes domínios. No contexto empresarial, SOA permite que organizações, que tenham uma infra-estrutura de aplicações fragmentadas sob a administração de diferentes áreas de negócio, possam integrar estas aplicações no nível de serviço. Por um lado, os processos de arquitetura tradicionais não abrangem estes aspectos de SOA. Por outro lado, as abordagens de SOA disponíveis não satisfazem todos os fundamentos da arquitetura de software. Neste sentido, esta dissertação propõe um processo sistemático de arquitetura de software baseado em SOA que compreende os principais fundamentos da arquitetura de software e características inerentes a SOA a fim de guiar os arquitetos na construção de uma descrição arquitetural para SOA. Adicionalmente, um estudo experimental foi definido, planejado, executado e analisado a fim de avaliar o processo proposto

Full textInformationsteknik blir allt viktigare för både enskilda individer och för organisationer. IT låter oss inte bara arbeta snabbare och effektivare med det vi redan gör, utan låter oss också göra helt nya saker, organisera oss annorlunda och arbeta på nya sätt. Tyvärr har dessa fördelar ett pris: i takt med att vi blir alltmer beroende av IT-tjänster ökar också våra krav på att de är ständigt tillgängliga för oss, utan avbrott. Trots att tillförlitlighetstekniken går framåt utgör dagens alltmer sammankopplade system en svår utmaning i detta avseende. Hur kan man säkerställa hög tillgänglighet hos IT-tjänster som ständigt byggs ut och uppgraderas, som har livscykler på tiotals år, som är beroende av tredjepartsleverantörer och som dessutom måste leva upp till verksamhetskrav på att vara flexibla och agila? Den här avhandlingen innehåller (i) ett arkitekturramverk som på ett unikt sätt kan analysera IT-tjänsters tillgänglighet och ta fram rekommenderade åtgärder, (ii) ett antal identifierade kausalfaktorer som påverkar IT-tjänsters tillgänglighet, (iii) en studie av hur felträd kan användas för arkitekturanalys av tillgänglighet samt (iv) en uppsättning principer för beslutsfattande kring tillgänglighet. Avhandlingen är en sammanläggningsavhandling med fem artiklar. Artikel 1 innehåller ett konceptuellt ramverk för beslutsfattande kring IT-tjänsters tillgänglighet som understryker vikten av variansen hos nertidskostnaderna. Artikel 2 visar hur ramverk för organisationsövergripande arkitektur (s.k. enterprise architecture -- EA) kan utvidgas med felträdsanalys (FTA) och bayesianska nätverk (BN) för analys av beroenden mellan komponenter. FTA och BN är bägge etablerade metoder för tillförlitlighets- och tillgänglighetsmodellering. Artikel 3 beskriver en bayesiansk prediktionsmodell för systemtillgänglighet, baserad på utlåtanden från 50 experter. Artikel 4 kombinerar FTA med modelleringselement från EA-ramverket ArchiMate till en metod för tillgänglighetsanalys på verksamhetsnivå. Metoden har validerats i fem fallstudier, där de estimerade årliga nertiderna alltid låg inom åtta timmar från de faktiska värdena. Artikel 5 utvidgar den bayesianska prediktionsmodellen från artikel 3 och modelleringsmetoden från artikel 4 till ett fullständigt EA-ramverk som uttrycks i en probabilistisk version av Object Constraint Language (OCL). Det resulterande modelleringsramverket har testats i nio fallstudier på verksamhetsstödjande IT-system.

Full textGovernments 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.
