Applying Practice Theory to Develop Functional Requirements SpecificationsNittler, Lovisa January 2024 (has links)
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.

Previous issue date: 2007-02-10 / The alterations to the way knowledge is produced and the great amount of documents stimulate and pressurize into changes in cataloguing. 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.

Previous issue date: 2014-02-26 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / In the context of Software Engineering, web accessibility is gaining more room, establishing itself as an important quality attribute. This fact is due to initiatives of institutions such as the W3C (World Wide Web Consortium) and the introduction of norms and laws such as Section 508 that underlie the importance of developing accessible Web sites and applications. Despite these improvements, the lack of web accessibility is still a persistent problem, and could be related to the moment or phase in which this requirement is solved within the development process. From the moment when Web accessibility is generally regarded as a programming problem or treated when the application is already developed entirely. Thus, consider accessibility already during activities of analysis and requirements specification shows itself a strategy to facilitate project progress, avoiding rework in advanced phases of software development because of possible errors, or omissions in the elicitation. The objective of this research is to develop a method and a tool to support requirements elicitation of web accessibility. The strategy for the requirements elicitation of this method is grounded by the Goal-Oriented approach NFR Framework and the use of catalogs NFRs, created based on the guidelines contained in WCAG 2.0 (Web Content Accessibility Guideline) proposed by W3C / No contexto de Engenharia de Software, a Acessibilidade Web vem ganhando cada vez mais espa?o, se firmando como um importante atributo de qualidade. Esse fato se deve a iniciativas de institui??es como a W3C (World Wide Web Consortium) e ao surgimento de normas e leis como a Section 508 que fundamentam a import?ncia de elaborar sites e aplica??es Web acess?veis. Apesar dessas melhorias, a falta de acessibilidade na web ainda ? um problema persistente, e pode est? relacionada ao momento ou a fase em que este requisito ? tratado dentro do processo de desenvolvimento. Tendo em vista que a Acessibilidade Web geralmente ? considerada como um problema de programa??o ou tratada quando o aplicativo j? est? totalmente desenvolvido. Dessa forma, considerar a acessibilidade j? durante as atividades de an?lise e especifica??o de requisitos se mostra uma estrat?gia para facilitar o andamento do projeto, evitando retrabalho em fases avan?adas do desenvolvimento de software por causa de poss?veis erros, falhas ou omiss?es na elicita??o. O objetivo desta pesquisa ? desenvolver um m?todo e uma ferramenta para apoiar a elicita??o dos requisitos de acessibilidade web. A estrat?gia de elicita??o presente neste m?todo ? fundamentada atrav?s da abordagem orientada a metas do NFR Framework e na utiliza??o de cat?logos de RNFs, criados com base nas diretrizes contidas no WCAG 2.0 (Web Content Accessibility Guideline) proposto pela W3C

Supportability Engineering in Wind Power Systems - Who Cares? : Considering important stakeholders and their requirementsCiganovic, Renato January 2011 (has links)
Wind power is one of the fastest growing energy sources, which have advantages in terms of delivering clean, cheap and fast energy. Many actors and organizations have realized this potential, which has lead to exponential growth of the wind power over recent couple of years. Despite promising future of clean and green energy through wind there are still areas to be improved to tackle main hinders for further development on a larger scale. The larger scale development of wind power has up-to-date been reached in only few countries such asDenmarkandGermany. The most potential can be found through offshore wind turbines due to, among other, lesser height and noise restrictions than inland wind turbines as well as better wind resources. This thesis is mainly characterized by the mixed-method method, which is in its turn characterized by mixing different research methods such as induction, deduction and abduction as they might be suitable to apply during the different stages of the research process. In this thesis the system approach will be considered to model the scope of this study’s context. As this thesis was constructed as a theoretical study the systematic literature review was used as the main source for data collection. The synthesis of the reviewed articles was initially performed in a broad manner to show overall picture of research related to the scope of this thesis. In the following step, the adopted LCM tool was used to extract study specific data from the reviewed and additional articles. This enabled to link some of the current problems, in wind power area, and ‘unfulfilled’ stakeholder requirements. This thesis aim was to identify important stakeholders and to address their respective requirements within the scope of supportability engineering applied in the wind power context, particularly stakeholder requirements that have not been considered by previous research. The purpose of it was to compare different requirements with current issues in the wind power sector. Conducted systematic literature review showed significant and costly (development) issues related to the supportability engineering such as reliability, availability, maintainability, accessibility problems etc. This was fully in line with the stakeholders’ requirements, which in several cases demanded higher dependability i.e. availability performance and its influencing factors. The thesis also included definition of supportability engineering framework, through comparing several widely accepted and standardized theoretical concepts. This comparison enabled definition of more focused approach with requirements on the ‘supported system’ and to lesser extent the ‘support system’. These requirements are usually mixed within the different theoretical concepts. The main findings from this study are that application of supportability engineering framework would lead to earlier identification of important stakeholders and their requirements. Considering these requirements, for instance availability and maintainability of the wind turbines, at earlier stages of the life cycle through better design and improved supportability infrastructure could potentially decrease amount of current problems in the wind energy sector in particular for the offshore part. Another result was that different stakeholders and their requirements were identified. Thesis contribution overall was a new ‘refined approach’ to deal with supportability issues through supportability engineering framework, whose main focus is the ‘supported system’.

Exploring issues in agile requirements engineering in the South African industrySebega, Yanda 01 1900 (has links)
The agile manifesto has certainly changed the way software is produced in the Information Communications Technology (ICT) industry. However, many persistent challenges cripple agile software development. One challenge is that the constant change in technology makes the requirements hard to implement. Another is that issues of the agile requirements engineering (ARE) process are abundant and pervasive throughout software projects. The aim of this study is to determine common issues in agile requirements engineering in the South African software industry and identify tools and frameworks to mitigate risks emanating from such problems. This includes finding out how much value software practitioners put in the agile principles. This study was essentially quantitative, based on a cross-sectional survey. Self-administered questionnaires were used to collect required data which was then subjected to exploratory data analysis using SPSS (Statistical Package for the Social Sciences), a tool for statistical analysis. The results show that software practitioners have a strong penchant for principles of the Agile Manifesto. Major issues in agile requirements engineering include lack of proper validation tools and techniques, scope problems, lack of proper documentation, issues of prioritisation, as well as unavailability of customer representative. A detailed baseline of issues in agile requirements engineering was created along with a set of recommended tools and techniques used in the software industry. As for the recommendation, it is suggested that companies invest more on validation tools and techniques and consider non-functional requirements integration during software development. / School of Computing / M.

Atributy vyjádření a provedení - realita v souborných katalozích versus informační potřeby uživatelů / Attributes of expression and manifestation - reality in library catalogs vs. information needs of usersTůmová, Markéta January 2017 (has links)
The aim of the thesis is to explore which attributes of expression and attributes of manifestation are commonly found in bibliographic records and compare them with the information needs of users. The research is focused on the Union catalog of the Czech Republic - CASLIN. In the theoretical part there are presented problems with attributes of expression and attributes of manifestation in model FRBR. In the research part there was performed content analysis of several bibliographic records owing to problems of attributes of expression and attributes of manifestation. In the research section there was made the analysis of information needs of users, too. As qualitative research methods were selected observation of participants and semi-structured interviews with respondents. The result of this thesis should be a comparison between reality in library catalogs and information needs of users.

Granskning av tilllgänglighetsmått i små bostäder : För att öka och underlätta projekteringen av ungdoms- och studentlägenheter / Examination of accessibility dimensions in small residences : To enhance and facilitate the planning of youth and student apartmentsSköld, Sara, Tengsved, Loise January 2014 (has links)
Bostadsbristen för unga växer i takt med att fler byggherrar avstår från att bygga små lägenheter, då rådande lagar gör det svårt att på ett gynnsamt sätt producera kostnads- och yteffektiva bostäder. Bostäder har i dag krav på sig från kommuner och beställare att uppfylla svensk standard. Däri har handikapporganisationer drivit fram tillgänglighetskrav som medför att alla nyproducerade bostäder är tillgänglighetsanpassade. Genom att ifrågasätta svensk funktionshinderspolitik i samband med bostadsbyggande har detta examensarbete som mål att hitta lösningar för att öka nyproduktionen av små bostäder. Granskningen resulterade i ett förslag till en ny standard för ungdoms- och studentbostäder vilken underlättar vid projektering av mindre enskilda bostadslägenheter. / The housing shortage for young people is growing as more developers refrain from building small houses since current laws make it difficult to favorably produce space-efficient buildings. Buildings must, as requirements from municipalities and clients, achieve the Swedish Standard. A standard where disability organizations have driven the availability requirements that entail that all new buildings are adapted for accessibility. By questioning the Swedish disability policy related to the building trade this thesis aims to find solutions to increase the new constructions of small apartments. The result became a proposal to a new standard for youths and students apartments, simplifying the planning of small apartments.

[pt] ACELERANDO A ELICITAÇÃO DE REQUISITOS NÃO FUNCIONAIS / [en] SPEEDING UP NON FUNCTIONAL REQUIREMENTS ELICITATIONROXANA LISETTE QUINTANILLA PORTUGAL 14 August 2020 (has links)
[pt] Considerando a disponibilidade do Big Data para engenharia de software, como no caso do GitHub, a semi-automação da elicitação de requisitos não funcionais (NFRs) é uma estratégia fundamental para a definição de requisitos. Como tal, a elicitação de NFRs, dentro da automação da leitura de documentos, pode gerenciar a massa de informações valiosas existentes nos dados disponíveis. Esta tese explora esse contexto em três partes, a escolha de fontes apropriadas de informação, uma elicitação de descoberta de fatos e a identificação de NFRs. As avaliações realizadas mostraram que a automação enfrenta um balance entre eficiência e eficácia. Esse equilíbrio é detalhado com diferentes estratégias inovadoras. O conhecimento adquirido é organizado como um catálogo SIG (Softgoal Interdependence Graph). / [en] Considering the availability of Big Data for software engineering, as the case of GitHub, the semi-automation of non-functional requirements (NFRs) elicitation is a key strategy towards requirements definition. As such, NFRs elicitation, within the automation of document reading, can manage the mass of valuable information existing in available data. This thesis explores this context in three parts, the choice of proper sources of information, a fact-finding elicitation, and NFRs identification. The assessments performed showed that the automation faces a trade-off between efficiency and efficacy. This trade-off is detailed with different novel strategies. The acquired knowledge is organized as a SIG (Softgoal Interdependence Graph) catalog.

Bärande innerväggar av KL-trä, armerad betong och oarmerad betong i flerbostadshus : Jämförelse av koldioxidutsläpp och kostnader för lägenhetsavskiljande samt icke lägenhetsavskiljande väggarHahne, Felix, Blank, Filip January 2023 (has links)
Denna studie presenterar en jämförelse mellan KL-trä och olika former av betong (armerad/oarmerad och platsgjuten/prefabricerad) som väggmaterial i byggnadskonstruktioner. Syftet är att analysera deras respektive miljöpåverkan och kostnadseffektivitet. Trots en initialt högre kostnad per kvadratmeter, har KL-trä en betydligt lägre miljöpåverkan, vilket medför en nettovinst för miljön jämfört med betongväggarna. Bland betongalternativen uppvisar oarmerad platsgjuten betong en balans mellan lägre kostnader och mindre CO2-utsläpp. Studien lyfter fram behovet av standardiserade, pålitliga data om miljöpåverkan inom byggindustrin för att stödja hållbara beslut. Den pekar på potentialen i ytterligare forskning som syftar till att reducera både kostnader och miljöpåverkan för KL-trä, för att främja dess bredare användning i byggsektorn. Studien erbjuder därmed viktiga insikter för att driva en mer hållbar och ekonomiskt lönsam byggindustri. / This study presents a comparison between CLT and various kinds of concrete (reinforced/unreinforced and cast in place versus prefabricated) as wall material in building constructions. The purpose is to analyse their respective environmental impact and cost efficiency. Despite an initially higher cost per square meter CLT has a considerably lower environmental impact, which entails a net profit for the environment compared to the concrete walls. Among the concrete options, walls without rebar and cast in place exhibits a balance between lower costs and CO2eemissions. This study highlights the need of standardized, trustworthy data of the environmental impact in the construction industry to support sustainable decisions. It points to the potential in further research which intends to reduce both cost and environmental impact for CLT, to further promote its use in the construction industry. The study thus offers important insights for driving a more sustainable and economically profitable construction industry.
