is study has focused on the technical sustainability dimension of sustainable soŸware engineering. Sustainabilitywithin soŸware engineering is something that has recently started to gain traction, where most of theresearch has focused on the environmental dimension.e purpose of this study was to investigate the technicalsustainability dimension, and contribute by continuing to build upon previous research which has suggestedsustainability as a part of non-functional requirements and as a part of soŸware quality.is study was conducted with a qualitative approach. is approach used interviews with people withexperience of working in soŸware development to collect data. e interviews were used to gain in-depthinformation of the dišerent aspects in soŸware development, e.g. development processes.e results, based on the interviews, showed that from a technical sustainability perspective there are issueswith where the focus of the work is in soŸware development and also problems related to how timemanagementis used.e results also showed that there was some lacking in understanding the benets and tradeošs ofdecisions made in the project, for example regarding the soŸware design, which can result in unnecessarycomplexity is acquired.e study found that the culture within soŸware development projects and companies needs to be changedtowards a culture which promotes the development of high quality soŸware. Because non-functional requirementsand soŸware quality are components of technical sustainability, therefore is the technical sustainabilityhigher if the quality is high. It was further found that this culture would be possible if changes were made tothe way prioritisations are made, and the way testing is performed should be extended. Finally it was foundthat the understanding of the benets and tradeošs of decisions and ideas needs to be increased and extendedcollectively.e study concluded that the technical sustainability dimension can be achieved through these changes andthat the problem and solution therefore are not small and local but rather a big and complex issue where thesolution spans several solutions that encompasses dišerent aspects and perspectives.

Information Technology (IT) has become a vital tool for most industrial businesses and Scania CV AB is no exception. As the importance of IT generally has increased, the usage and number of applications has grown as well. Applications are substantial assets for an organization that is heavily supported by IT. Consequently, a way of managing applications efficiently and sustaining the costs of applications rather low ? doing more with less ? is required. In addition it is also important, from a business perspective, that applications as part of IT are aligned with business strategies and goals. Application Portfolio Management (APM) is a practice and a business-centric activity aimed to allocate IT resources to support business objectives and strategies; it helps determining the impact of applications and the relative importance of each application in the portfolio to the business. APM attempts to justify and measure the financial benefits of each application relative to the costs of the applications? maintenance and operations. Performing APM successfully is nevertheless a complicated issue, and something that many businesses are challenged with on a daily basis. New applications are constantly and regularly added, downloaded, purchased or selfdeveloped ? too often without any further control. In order to regain the control of the software that automates the business, and ensuring that the applications adds value and reliability to the company, Scania CV AB requires a rigorous and comprehensive method for an APM approach. In this master thesis together with Camilla Palomeques?s thesis1, such a method is provided. These two theses also offer a suggestion on how to proceed with the APM effort at Scania CV AB.

Low response time is an important factor for any interactive system. However, web-based applications suffer sometimes from bad response times. This fact is not always important but for services depending on a  high degree of interactivity it can be severe. This thesis attempts to give an answer to the question whichi s the requirements engineering for best response time on a highly interactive Web-based application? The research approach is deductive based on a single-case study and using qualitative method. The case system is a web-based system that supports an experimental technique called Wizard-of-Oz. To tackle the research question an extensive review of literature on requirements engineering was made, and, for the case study itself, system requirements documents and interviews were included. The results include information about the specific requirements engineering process for the case system, response time, and quality attributes.The conclusion indicates the importance of response time requirements, hardware and software requirements, testing, but also a demonstration phase for desired interactive behaviour including response time. The latter is not previously identified as a major step in the general literature on requirements engineering but should definitively be noted by researchers and practitioner alike.

The increased sophistication of customer needs pushes manufacturers toward integrated offerings where physical products and intangible services collaboratively generate value, also known as Product-Service Systems (PSS). This shifts the focal point from product performance to overall system functionality. However, this naturally increases the importance of requirements linked to the operation and the system's behavior, e.g., reliability, safety, and flexibility. These kinds of requirements that dictate how a system should behave and operate in its context are called non-functional requirements. However, most manufacturing firms have a legacy of focusing mainly on functional requirements.  Alongside this trend, there has been an increasing affordability and availability of data. However, how this data can be utilized for value creation remains a question for the industry. Operational data can serve as a vital source of information about the PSS behavior and value delivery process. Since non-functional requirements depend on the operational context for measuring their performance, operational data can thus provide new insights.  This thesis aims to study the motivation for and challenges of working with non-functional requirements and value within Digital PSS design by manufacturing firms. Firstly, the management of non-functional requirements in the design process is studied. The empirical research determined that there are six challenges that a design team and organization face when working with non-functional requirements. The challenges highlight that non-functional requirements’ fuzzy and intangible aspects make them easy to neglect and hard to include in design and decision-making. A state-of-the-art review is conducted to identify possible remedies. Onward, the intersection between data and value is explored. An overarching classification of operational data and how these can contribute to different forms of value creation is presented based on previous literature. Further, the analysis shows what kind of operational data can be collected using three levels of granularity. Experiences and reflections from multiple companies at different stages in their servitization journey are gathered to complement and expand the perspective on operational data and value.

[pt] Mesmo com o processo de refatoração sendo investigado cada vez mais nos últimos anos, muitas de suas características se mantém pouco compreendidas. Refatoração de software é o processo de melhorar a manutenibilidade de um sistema por meio de mudanças estruturais que não alteram seu comportamento. Estudos recentes revelaram que projetos de software frequentemente recebem refatorações compostas. Em tais refatorações, desenvolvedores aplicam uma série de transformações únicas em conjunção e em um único commit, e se espera que estas refatorações tenham um efeito maior e mais positivo do que refatorações singulares. Porém, refatorações frequentemente causam mudanças que ou mantém a qualidade do software da mesma forma, ou causam a piora do mesmo, levando trabalhos recentes a procurar causas em potencial para este comportamento. Porém, o porquê da complexidade destas mudanças compostas frequentemente afetarem seus resultados de alguma forma positiva ou (inesperadamente) negativa continua não investigado. O mesmo ocorre com o potencial efeito das preocupações dos desenvolvedores durante a aplicação de refatorações. Sobre estas preocupações, alguns trabalhos anteriores foram desenvolvidos em torno da caracterização e detecção de discussões de desenvolvedores relacionadas a refatorações. Porém, não se sabe se e como estas preocupações de desenvolvedores com refatorações, tornando-se explícitas em tais discussões, podem influenciar os efeitos de refatorações em um sistema. Portanto, este trabalho apresenta dois estudos com o objetivo de preencher a lacuna no conhecimento de que causas levam aos efeitos não-positivos frequentemente encontrados em refatorações, procurando entender: (i) se refatorações mais complexas realmente são mais efetivas do que refatorações simples, como esperado; (ii) em que situações desenvolvedores tendem a explicitar suas preocupações com refatoração do código; e (iii) qual é o impacto de tais preocupações na efetividade de uma refatoração em melhorar a qualidade estrutural do código. Nós analisamos estas características e atingimos os seguintes resultados: Primeiro, conforme a complexidade das refatorações aumenta, a efetividade das mesmas aumenta conjuntamente. Segundo, há uma relação entre a efetividade de refatorações e preocupações explícitas com refatorações, onde a possibilidade de efeitos negativos é menor quando desenvolvedores estão explicitamente preocupados com refatoração. Finalmente, desenvolvedores tendem a explicitar mais frequentemente suas preocupações com o processo de refatoração quando deparados com tarefas de refatoração mais complexas. / [en] Even though the refactoring process has been increasingly investigated in the last years, many of its characteristics remain poorly understood. Software refactoring is the process of improving the maintainability of a system through structural changes that do not alter its behaviour. Recent studies revealed that software projects frequently have to undergo composite refactorings. In such refactorings, developers perform a series of single transformations in conjunction and in a single commit, which are expected to have a larger and more positive impact than single refactorings. However, refactorings frequently cause changes that either keep the software quality the same, or cause it to worsen, which lead recent works to look for potential causes of this behavior. However, the complexity of these composite changes often affecting their outcomes in some positive or (unexpectedly) negative way remains not investigated, much like the developers concerns while performing refactoring. For the latter, some previous work was performed around characterizing and detecting refactoring-related developer discussions. However, it is unknown whether and how developers refactoring concerns made explicit in such discussions can influence the refactorings effects on a system. Thus, this work reports two studies aimed at bridging some of those gaps in knowledge in which causes lead to the non-positive effects frequently found in refactoring, by understanding: (i) if more complex refactorings are indeed more effective than simple refactorings, as one would expect; (ii) in which situations developers tend to have explicit concerns while refactoring the code; and (iii) what is the impact of such concerns on the effectiveness of a refactoring to improve structural quality. We analyze these characteristics and reach the following results: First, as refactoring complexity increases, the effectiveness of such refactorings increases as well. Second, there is a relationship between refactoring effectiveness and explicit refactoring concerns, in which the possibility of negative effects is lower when developers are explicitly concerned about refactoring. Finally, developers tend to be more explicit about their concerns on the refactoring process when they are faced with more complex refactoring tasks.

[pt] Em função do ritmo acelerado com que tem surgido inovações de mercado, com as incertezas econômicas, a ascensão de mídias sociais, violações cibernéticas, e diversos outros fatores, os riscos organizacionais tem se tornado cada vez mais complexos e difíceis de serem geridos. É necessário que pensemos em modelos mais completos de representação de informações que possam interpretar os riscos aos quais as empresas estão expostas da maneira mais clara e detalhada possível. A modelagem i-estrela permite que informações sejam representadas sem que sejam excluídos detalhes relevantes para a gestão de riscos das organizações. Este artigo propõe uma modelagem de gestão de riscos por meio do modelo i-estrela, de forma a atender a necessidade de representação de informações complexas no atual ambiente de negócios empresarial. / [en] Due to the accelerated pace with which market innovations have emerged, with economic uncertainties, the rise of social media, security issues, and many other factors, organizational risks have become increasingly complex and challenging to manage. It is essential to think about more complete models of information representation that can interpret the risks to which companies are exposed, as clearly, and detailed as possible. The intentional modeling approach allows information to be represented without excluding details relevant to organizations risk management. This paper proposes a risk management modeling strategy using the iStar language to address the need for enhanced information representation in today s enterprise business environment.

Purpose - This study investigated how practice theory could enhance the Requirements Engineering elicitation process in IS development, focusing on addressing the misalignment between user needs and system functionalities. The research centered on the question: How can practice theory be used to formulate functional requirements specifications in system development? The specific practice examined was the Cybersecurity Maturity Assessment (CMA) at a cybersecurity company. Methodology - This qualitative study used semi-structured interviews to collect data from seven participants with expertise in conducting or overseeing CMA processes. The interview questions were based on Schatzki's Practice Theory: teleoaffective structures, understandings, rules, and material arrangements. Thematic analysis was applied to extract relevant themes and patterns. Findings - The results reveal that integrating practive theory in the elicitation stage of RE deepens the understanding of user practices and challenges. It helps to reveal not only the explicit needs but also the implicit and tacit knowledge that shapes user's interactions with systems. Conclusion - The study concludes that practice theory provides a valuable addition to the traditional elicitation step of the RE process. This research contributes to both the practice and theory of IS development by showing how the integration of sociological theories can improve technological processes and lead to the creation of more efficient and user-centered information systems.

In this context, a theoretical model for cataloguing known as Functional Requirements for Bibliographic Records (FRBR) was published in 1998. Generally speaking, the cataloguing codes are divided into two parts: one related to description and another to the access points. This work aims to analyse the procedures to choose the access points of personal responsibility of the bibliographic records, in order to relate them to the concepts shown in the FRBR. The present work is characterized as a theoretical search and the investigation resorts to deductive approach to analyse the rules and the internationally accepted principles utilized in the choice of the access points. This search also has an empirical part to collect factual data about the use of cataloguing rules and to compare the registers with or without the use of the FRBR. As a result, it is observed that the cataloguing rules are still directed to the impressed catalogues. However, the concepts presented by the FRBR are related to the automated catalogues. The FRBR enlarge the dimensions of the responsabilities about the content of work and expression, and they translate the social changes to the possibilities of information representation in the bibliographic records. With the FRBR the rules have to be stipulated to facilitate the user activities. This implies in the review of the cataloguing rules, mainly the ones related to the choice of the access point. In this way, the professional of information will pay more efforts to determine which the access points for the user are. Among the uncountable impacts caused by the FRBR, perhaps the most important are to resume the discussion about the cataloguing in theoretical level and to highlight the importance of intellectual work of professional of information. / As altera??es na forma de produ??o do conhecimento e o grande volume de documentos pressionaram e estimularam mudan?as na cataloga??o. Nesse contexto, foi publicado em 1998 um modelo te?rico para a cataloga??o conhecido como Requisitos Funcionais para Registros Bibliogr?ficos (FRBR . Functional Requirements for Bibliographic Records). Em geral, os c?digos de cataloga??o s?o divididos em duas partes: uma destinada ? descri??o e outra aos pontos de acesso. Este estudo teve como objetivo analisar os procedimentos para a escolha dos pontos de acesso de responsabilidade pessoal do registro bibliogr?fico, relacionando-os com os conceitos apresentados nos FRBR. Caracterizada como uma pesquisa te?rica, a investiga??o recorreu ? abordagem dedutiva para analisar as regras e os princ?pios aceitos internacionalmente utilizados na escolha dos pontos de acesso. A pesquisa tamb?m possui uma parte emp?rica para coletar dados factuais sobre a aplica??o de regras de cataloga??o e comparar os registros com e sem a base dos FRBR. Como resultado, observou-se que as regras da cataloga??o ainda se direcionam aos cat?logos impressos. No entanto, os conceitos apresentados pelos FRBR se relacionam aos cat?logos automatizados. Os FRBR ampliam as dimens?es das responsabilidades sobre o conte?do de uma obra e express?o, traduzindo as altera??es sociais para as possibilidades de representa??o da informa??o nos registros bibliogr?ficos. Com os FRBR as regras devem ser estipuladas para facilitar as atividades dos usu?rios. Isto implica na revis?o das regras de cataloga??o, especialmente as relacionadas ? escolha dos pontos de acesso. Assim, o bibliotec?rio empenhar? mais esfor?os para determinar quais ser?o os pontos de acesso necess?rios aos seus usu?rios. Dentre os in?meros impactos provocados pelos FRBR, talvez, os de maior destaque sejam a retomada das discuss?es sobre a cataloga??o em n?vel te?rico e o realce da import?ncia do trabalho intelectual dos profissionais.
