Nesse contexto, o gerenciamento de TI vem evoluindo para incluir gerenciamento de serviços e governança de TI, apontando para paradigmas de gerenciamento de TI orientado ao negócio. Dessa forma, o alinhamento entre a TI e o negócio tem sido considerado como um dos fatores preponderantes para a efetividade de tais paradigmas. Em adicional, são mencionadas as contribuições provenientes da automação das atividades de gerenciamento. Acompanhando essa evolução, o gerenciamento de configuração desempenha um papel fundamental, fornecendo informações precisas da TI a todos os envolvidos no gerenciamento. Todavia, em função desse estreito relacionamento com todas as entidades ligadas ao gerenciamento, a interoperabilidade entre esses componentes tem sido caracterizada como um dos principais desafios de pesquisa em gerenciamento de redes e serviços. Nesse sentido, o uso de ontologias, em especial ontologias de fundamentação, tem sido indicado como uma maneira pro issora de se obter interoperabilidade semântica no domínio de gerenciamento de configuração, uma vez que elas expressam o significado dos conceitos do domínio, bem como os relacionamentos existentes entre eles, de forma clara e explícita. Além disso, ontologias permitem que esse significado seja definido em um formato legível por máquinas, tornando o conhecimento compartilhado não apenas por agentes humanos, mas também por sistemas computacionais, possibilitando a automação de processos. Assim, esta dissertação apresenta uma proposta de modelagem conceitual do domínio de gerenciamento de configuração, no contexto do gerenciamento de serviços e governança de TI, baseada em ontologias de fundamentação. O propósito dessa ontologia é prover um modelo conceitual desse domínio, comprometido em maximizar a expressividade, a clareza e a veracidade dos conceitos pertencentes a ele. Ademais, esta dissertação apresenta uma proposta de modelo de implementação, derivado do modelo conceitual desenvolvido. O objetivo é realizar uma prova de conceito da ontologia e também demonstrar como essa ontologia pode apoiar as atividades de gerenciamento de maneira automatizada / Information technology (IT) is becoming essential for organizations. In this context, IT management has evolved to include service management and IT governance, towards business driven IT management paradigms. Thus, the alignment between IT and business has been regarded as one of the leading factors for the effectiveness of such paradigms. Furthermore, contributions arising from management activities automation are mentioned. Following this evolution, configuration management plays a key role in providing accurate IT information to all involved in management. However, due to this close relationship with all entities related to management, interoperability among these components has been characterized as one of the main research challenges in network and service management. In this sense, the use of ontologies, foundational ontologies in particular, has been indicated as a promising way to achieve semantic interoperability in the configuration management domain, since they express the meaning of domain concepts, as well as the existing relationships between them, in a clear and explicit way. Moreover, ontologies allow that this meaning be defined in a machine readable format, making the knowledge shared not only by human agents, but also by computer systems, enabling process automation. Thus, this dissertation proposes a conceptual model of configuration management domain in the context of service management and IT governance, based on foundational ontologies. The purpose of this ontology is to provide a conceptual model of this domain, committed to maximizing the expressiveness, clarity and truthfulness of concepts that belong thereto. Moreover, this dissertation proposes an implementation model, derived from the developed conceptual model. The goal is to perform an ontology proof of concept and also demonstrate how this ontology can support the management activities in an automated way

Omvärlden förändras i en allt snabbare takt, vilket också försvårar driften av organisationer. Detta leder till ökad komplexitet av verksamheters applikationer och ökar kraven på IT-tjänsterna. Fokus behöver därför skiftas från den traditionella synen på IT och IT-förvaltning till en mer kund och tjänsteorienterad syn vilket kallas för IT Service Management (ITSM). Inom ITSM finns det ett antal ramverk och IT Infrastructure Library (ITIL) är det mest populära. ITIL är ett ramverk som fokuserar på processer och funktioner för att leverera och hantera en verksamhets IT-tjänster. ITIL syftar till att skapa fördelar såsom att förbättra tjänstekvalitén, minska kostnader, bli mer tidseffektiva, skapa bättre standarder och i slutändan förbättra kundnöjdheten.Det finns dock ett antal problem som verksamheter stöter på vid användningen av ITIL. För att kunna utnyttja och ta del av de fördelar som ITIL bidrar med, är det viktigt att kunna hantera dessa problem. Ett vanligt misstag är dock att fokus läggs på symptomen istället för den grundläggande orsaken. Syftet är därför att få en helhetsförståelse för de problem som uppstår vid användandet av ITIL, vilka orsakerna är och hur de kan hanteras. För att besvara frågeställningen utfördes en kvalitativ undersökning via semi-strukturerade intervjuer med tre respondenter som har praktisk erfarenhet av ITIL.Intervjuerna visade att respondenterna till stora delar plockade fram liknande problem, och att många av dem grundar sig i samma orsak. Exempel på problem som identifierades var att många hoppar över de strategiska processerna och att det råder en missuppfattning gällande ITIL. Den vanligaste orsaken visade sig vara okunskap, och att de inte vet hur det skall användas. Ett annat problem var att tjänsteleverantören inte efterföljer de införda ITIL-processerna och en orsak till detta visade sig vara att verksamheter har svårt att påvisa nyttan med ITIL. Detta visade sig kunna hanteras genom att analysera mätningar och använda dessa som underlag för att förklara varför ramverket används. / The world is changing rapidly, which complicates the management of organizations and leads to an increased complexity of an organisations applications as well as increased demands. Therefore the focus needs to change from the traditional aproach of IT-management to a more customer and service oriented view, which is called IT Service Management (ITSM). Within ITSM there is a couple of frameworks and standars, and the most popular is IT Infrastructure Library (ITIL). ITIL is a framework that focus on processes and functions to deliver and manage an organizations IT-services. ITIL aims to create advantages such as improved service quality, reduced costs, to be more time-efficient, create better standards which leads to improved customer satisfaction.However, there are a number of problems that businesses encounter when using ITIL. In order to utilize and take advantage of the benefits that ITIL is supposed to create, it is important to deal with these problems. However, a common mistake is to focus on the symptoms rather than the root cause. Therefore the aim of this study is to offer a holistic view of the problems arising from the use of ITIL, what the causes are and how they can be managed. To answer theese questions a qualitative study was conducted using semi-structured interviews with three respondents that have practical experience of ITIL.The analysis showed that the respondents identified similar problems, and that many of them are based in the same cause. Examples of identified problems is that it´s common to ignore the strategic processes and that there is a misconception regarding ITIL. The most common cause were found to be lack of knowledge, and that they don´t know how to use the framework. Another identified problem is that the service provider does not comply with the introduced ITIL processes. One of the reasons for this proved to be that the organizations have difficulties to demonstrate the value of ITIL to the staff working with the processes. One way to manage this problem appeared to be by analyzing the metrics and use this as a basis to explain why the framework is used.

Aims and Objectives: Information Technology (IT) service management has gained importance in the recent years. A service is a means of delivering value to the customers by facilitating outcomes, which customers want to achieve without ownership of the specific costs and risks. As IT services’ efficient execution revolves around its implementation through software management, the need for understanding the relationship between IT service management and software management has become crucial. The aim of this thesis is to explore this relationship. Methodology: We designed this thesis study as an exploratory study. First, a systematic literature review was conducted to explore the role of software engineering in IT service management and the interconnection between them. Then, we performed a case study at Telenor Sweden AB by conducting interviews in order to further investigate the intersecting elements between ITIL v3 Framework, which is an international standard for IT service management and software engineering considering ISO/IEC 12207 standard on software processes. Results: The outcome of this thesis is a mapping between IT service management and software engineering considering ISO/IEC 12207 for software engineering processes and ITIL V3 Framework for IT service management. These mappings have been recommended to use by the case company to incorporate ‘in-house’ software models in line with ITIL V3 Framework implementation. Conclusion: Though ITIL V3 framework gives in depth guidelines for IT Service Management, it does not give sufficient details for managing applications that constitute IT Services. As ITIL V3 is a framework, it is flexible to accommodate the software engineering processes defined in ISO/IEC 12207 standard. Though we brought three-way relationship between ITIL V3, ISO/IEC 12207 and case company’s software process models, it is found out that replacing existing models with ISO/IEC 12207 shall be difficult as it would be two new standards for the employees. The in house software process models are already inspired from standards. In this thesis, we provide a mapping between ITIL V3 and inhouse models of the case company to support the implementation of ITIL V3 for managing software applications to realize IT Services. / The thesis gives mapping between ITIL V3 Framework and ISO/IEC 12207 Software Engineering processes to incorporate them in integrated Service Management and Software Management / +46762509249

More than ever, businesses heavily rely on IT service delivery to meet their current and frequently changing business requirements. Optimizing the quality of service delivery improves customer satisfaction and continues to be a critical driver for business growth. The routine maintenance procedure plays a key function in IT service management, which typically involves problem detection, determination and resolution for the service infrastructure. Many IT Service Providers adopt partial automation for incident diagnosis and resolution where the operation of the system administrators and automation operation are intertwined. Often the system administrators' roles are limited to helping triage tickets to the processing teams for problem resolving. The processing teams are responsible to perform a complex root cause analysis, providing the system statistics, event and ticket data. A large scale of system statistics, event and ticket data aggravate the burden of problem diagnosis on both the system administrators and the processing teams during routine maintenance procedures. Alleviating human efforts involved in IT service management dictates intelligent and efficient solutions to maximize the automation of routine maintenance procedures. Three research directions are identified and considered to be helpful for IT service management optimization: (1) Automatically determine problem categories according to the symptom description in a ticket; (2) Intelligently discover interesting temporal patterns from system events; (3) Instantly identify temporal dependencies among system performance statistics data. Provided with ticket, event, and system performance statistics data, the three directions can be effectively addressed with a data-driven solution. The quality of IT service delivery can be improved in an efficient and effective way. The dissertation addresses the research topics outlined above. Concretely, we design and develop data-driven solutions to help system administrators better manage the system and alleviate the human efforts involved in IT Service management, including (1) a knowledge guided hierarchical multi-label classification method for IT problem category determination based on both the symptom description in a ticket and the domain knowledge from the system administrators; (2) an efficient expectation maximization approach for temporal event pattern discovery based on a parametric model; (3) an online inference on time-varying temporal dependency discovery from large-scale time series data.

This thesis is concerned about Business Continuity Management with the focus on determination of the RTO and RPO parameters. The work is divided into two main parts. The first section briefly describes theoretical issues of Business Continuity Management in conjunction with IT Service Continuity Management. Then there are described various technologies that are currently used to ensure continuity and recovery of IT systems. In conclusion of the theoretical part, the work focuses on the process of Business Impact Analysis. This thesis thus offers a comprehensive view of main principles and benefits that these concepts have for company and how they should be integrated with each other. It provides an overview of various technologies, their link to RTO and RPO parameters and also the definition of steps of disaster recovery procedure. The work also briefly defines the basic procedure for determination of the RTO and RPO parameters, subsequent steps needed to design recovery solutions and analyzes various aspects which need to be considered when defining the parameters of continuity. The second practical part is based on the previous theoretically defined procedure and its aim is to analyze the data acquired during the questionnaire investigation in chosen company to determine the parameters of continuity for the applications in use and then suggest appropriate ways of addressing their backup and recovery. The result of this thesis is therefore a description of the analysis and practical application of methods for setting the parameters for continuity of information systems and the subsequent establishment of necessary measures.

Thesis Price models and SLA for shared services of data centers has as objective to establish best practice, so-called "best practices" of SLA and price models for data center services. Work is divided into two parts, theoretical and practical part. The theoretical section is wants to familiarize the reader with the basic concepts such as outsourcing, reasons and risks of use. I describe the base models for providing IT services as well as pricing models for services as described in the literature. I will focus on data centers and TIER standard categorization, too. The practical part is based on an analysis of information that I got from an interview with the experts working for the biggest data center companies in the Czech Republic. Based on this information, I tried to compile the best practices for creating pricing models for data center services that are actually used in practice. Specifically, the server housing, server hosting and virtual server services. Also, for these services create an SLA that can be used by some data center company in the Czech Republic.

The aim of the thesis is to provide a project delivery framework for IT Consultancy organizations. The framework will foster efficient planning, tracking and communication of requirements and deliverables between IT Consultancy and their customer during entire project lifecycle and will therefore enable repeatable and consistent high quality delivery of customer success.

This master's thesis is focused on Information Technology Infrastructure Library (ITIL). Objective of the project was to analyze, design and implement a game engine, which would provide simulation of IT service operation in real or accelerated time or in turns. Basic part of the engine is a creators mode, which allows users to create custom IT services and specify their behaviour during operation, like the service would be used in real. Another part of the engine is a players mode and simple service desk. In this mode, players can take care of fluent operation of their services. Thanks to this, they can learn and train practices, which are described in ITIL.
