Uma das áreas de pesquisa da Engenharia de Software é a Engenharia de Software Baseada em Valor – VBSE, a qual busca incorporar atividades de criação de valor nos processos de desenvolvimento de software. Segundo ela, o sucesso de um software vai mais além do que uma simples adequação a modelos técnicos. Excelência técnica é altamente desejável, mas insuficiente. Nos últimos anos, a utilização de métodos ágeis tem crescido de forma acentuada, sendo que, segundo pesquisas recentes, Scrum é o método ágil mais utilizado. Estes métodos têm como um de seus princípios a entrega de valor ao cliente. Desta forma, este trabalho analisou a aderência do Scrum à VBSE. A análise foi realizada tendo como base os princípios e valores definidos no manifesto ágil e os elementos-chave que formam a base da VBSE. O resultado da análise mostrou que o Scrum já é aderente a alguns desses elementos-chave. Entretanto, outros elementos-chave da VBSE não são abordados. Para preencher essas lacunas, foi proposta uma extensão que consiste na criação de novos artefatos e no acréscimo de atividades ao processo do Scrum. Tal extensão visa contribuir para que os softwares entregues criem valor para os interessados, sem descaracterizar a agilidade do Scrum. Como método de avaliação, foi aplicado um questionário a profissionais com experiência em Scrum a fim de verificar o grau de concordância em relação à extensão proposta. O resultado da avaliação mostrou que maioria dos respondentes concorda com a extensão e considera que a criação de valor para os interessados deve ser o objetivo principal de um projeto de software.

Measurement-based value alignment and reasoning about organizational goals and strategies:studies with the ICT industry

Mandić, V. (Vladimir) 04 September 2012 (has links)
Abstract Software and ICT companies fail due less to technological factors than socioorganizational factors, among which the most common is unrealistic goals and objectives. The socioorganizational factors are present in companies and organizations of all sizes. Organizations need to know whether their goals and strategies are working and whether the strategies are effectively providing a reasonable return on investment for the effort that is being applied, i.e. to understand how valuable they are for the organization. In addition, organizations need to recognize what the risks are in achieving those goals and evaluate their probability. And, when goals are set properly then they have directive and energizing functions, they tend to utilize available resources better and serve as activators of cognitive processes and knowledge sharing cycles. In this dissertation the GQM+Strategies approach was used. The approach was designed to help organizations to align goal-driven measurement schemes, i.e. GQM, with organizational goal hierarchy. The extensions developed in this dissertation (i.e., the solution proposed here) evolve the GQM+Strategies approach by providing an organization with capabilities to: (1) apply the work of value-based software engineering to directly address the return on investment (ROI) of their goals and strategies via evaluation of the costs and benefits of the goals and strategies chosen, (2) calculate a set of earned value metrics that allows organizations to effectively monitor the implementation of the organizational goals and strategies, (3) identify the risks associated with not achieving various sub-goals in a grid by analyzing goal risk exposures and acceptable risk levels, and (4) assess the threats of risky goals on other goals in the grid via evaluation of goal dependencies using the formal goal-strategies-goals models. The GQM+Strategies approach was piloted in four different organizations involving more than 60 participants. The feedback from the participants was used to identify the research questions posed in this dissertation. The research approach (solution development process) adopted the design science framework and utilized analytical and empirical paradigms in different phases of the solution development. The analytical paradigms were used for solution development and evaluation, while empirical paradigms where used for evaluating certain aspects of the solution. / Tiivistelmä Ohjelmisto- ja tietotekniikkayritysten epäonnistumiset johtuvat useimmin sosio-organisationaalisista tekijöistä kuin teknologisista tekijöistä. Näistä sosio-organisationaalisista tekijöistä yleisin on epärealististen tavoitteiden asettaminen. Sosio-organisatoriset tekijät ovat läsnä kaiken kokoisissa yrityksissä ja organisaatioissa. Organisaatioiden tulee tietää ovatko heidän tavoitteensa ja strategiansa toimivia ja tarjoavatko heidän strategiansa kohtuullisen tuoton suhteessa käytettyihin investointeihin. Toisin sanoen, organisaatioiden tulee ymmärtää kuinka arvokkaita heidän strategiansa ovat. Tämän lisäksi organisaatioiden täytyy kyetä tunnistamaan riskit asetettujen tavoitteiden saavuttamisessa sekä arvioimaan näiden riskien todennäköisyys. Kun tavoitteet on asetettu asianmukaisesti niillä on ohjaava ja energisoiva vaikutus. Ne sekä ohjaavat hyödyntämään tehokkaammin käytettävissä olevia rerursseja että toimivat kognitiivisten prosessien ja tiedonjakosyklien aktivaattoreina. Tässä väitöskirjassa käytettiin GQM+Strategies lähestymistapaa. Tämä lähestymistapa on suunniteltu auttamaan organisaatiota linjaamaan tavoitelähtöisiä mittausmenetelmiä, kuten GQM, organisaation tavoitehierarkian suhteen. Tässä väitöskirjassa esitetty laajennus kehittää GQM+Strategies lähestymistapaa tarjoamalla organisaatioille kyvykkyyksiä: (1) soveltaa arvoperustaisen ohjelmistotuotannon menetelmiä tavoitteiden ja strategioiden investoinnin tuottojen tarkasteluihin arvioimalla valittujen tavoitteiden ja strategioiden kustannuksia ja hyötyjä, (2) laskea joukko saavutetun arvon mittareita jotka mahdollistavat organisaatioille toteutettujen organisationaalisten tavoitteiden ja strategioiden tehokkaan seurannan, (3) identifioida riskejä jotka liittyvät eri alitavoitteiden saavuttamattomuuteen analysoimalla tavoiteriskeihin altistumista ja hyväksyttäviä riskitasoja ja (4) arvioida riskejä sisältävien tavoitteiden uhkia suhteessa muihin tavoitteisiin arvioimalla tavoitteiden riippuvuuksia käyttäen formaaleja tavoite-strategiat-tavoite -malleja. GQM+Strategies lähestymistapaa pilotoitiin neljässä organisaatiossa yhteensä yli 60 osallistujan kanssa. Tutkimuksen osallistujilta saatua palautetta käytettiin väitöskirjan tutkimuskysymysten identifiointiin. Tutkimuksen lähestymistavassa (ratkaisun kehittämisprosessi) sovellettiin design science -kehikkoa ja ratkaisun kehittämisen eri vaiheissa hyödynnettiin analyyttisiä ja empiirisiä paradigmoja. Analyyttisiä paradigmoja käytettiin ratkaisun kehittämisessä ja arvioinnissa ja empiirisiä paradigmoja ratkaisujen määrättyjen aspektien arvioinnissa.

Este tema envolve uma maior preocupação com o alinhamento dos projetos aos objetivos estratégicos das organizações. No contexto dos projetos de desenvolvimento de software, tal preocupação passa pela revisão das metodologias de desenvolvimento de software que os suportam. A Engenharia de Software Baseada em Valor (VBSE) é uma abordagem que adiciona considerações de valor aos aspectos técnicos da Engenharia de Software, estabelecendo um conjunto de elementos-chave necessários à evolução das técnicas e práticas atuais para que enfatizem a criação de valor. Este trabalho faz uma análise do Rational Unified Process, um framework de processos de software, quanto à ênfase em criação de valor que ele possibilita, usando os elementos-chave da VBSE como diretriz para a análise. Pontos de convergência entre o RUP e os elementoschave são identificados, e uma extensão do processo é proposta para suprir as lacunas encontradas. Uma avaliação do novo processo é feita e oportunidades para trabalhos futuros apresentadas

Systematic Mapping of Value-based Software Engineering : A Systematic Review of Value-based Requirements Engineering

Jan, Naseer, Ibrar, Muhammad January 2010 (has links)
Context: In many organizations, practices and processes of software engineering are carried out in a value-neutral setting. These value-neutral settings within software development are responsible for project failures. Value-based software engineering (VBSE) manages these value neutral settings by integrating value-oriented perspectives into software engineering. The fundamental factors that differentiate VBSE from value-neutral software engineering are value dimensions that play a crucial role in companies' success by managing customer needs, demands, and expectations Objectives: The aims of this master thesis are to 1) systematically classify the contributions within VBSE and 2) investigate practical application and validation of solutions in industry to determine their practical usability and usefulness. Methods: In this study, systematic mapping, followed by systematic review were used as research methods. Results: The findings of systematic mapping show that a clear majority of value-based research has been conducted within requirements engineering, and verification and validation. Whereas, there were not many studies discussing value-based design. In terms of research types used, evaluation research and solution proposal were the most dominant contributions. While experience reports and philosophical research were less emphasized. In general, value-based contributions such as recommendations and processes were highly reported in VBSE studies. In addition, the finding of systematic review indicates that although many solutions were proposed for value-based requirements engineering but in the absence of qualitative and quantitative results from usability and usefulness perspectives make it hard for practitioners to adopt for industrial practices. Conclusion: The systematic classification of studies and resulting maps not only give an overview of existing work on VBSE but also identifies interesting research gaps which can be used by researchers to plan and carry out future work. The findings of systematic review can be used by industry practitioners to assess the level of applicability of the proposed value-based requirements engineering solutions with respect to their application/validation context and usability and usefulness. / Naseer Jan, Cell: 0046736181463, Muhammad Ibrar, Cell: 0046760605212
