“…Seyff et al [22] developed a software environment called ART-SCENE to discover and document stakeholder requirements by walking through scenarios that are automatically generated from use case specifications. They created an extended mobile version called Mobile Scenario Presenter (MSP) using a mobile browser and wireless access to connect to the server-side ART-SCENE scenario system.…”

Abstract-Privacy requirements for mobile applications offer a distinct set of challenges for requirements engineering. First, they are highly dynamic, changing over time and locations, and across the different roles of agents involved and the kinds of information that may be disclosed. Second, although some general privacy requirements can be elicited a priori, users often refine them at runtime as they interact with the system and its environment. Selectively disclosing information to appropriate agents is therefore a key privacy management challenge, requiring carefully formulated privacy requirements amenable to systematic reasoning. In this paper, we introduce privacy arguments as a means of analysing privacy requirements in general and selective disclosure requirements (that are both content-and context-sensitive) in particular. Privacy arguments allow individual users to express personal preferences, which are then used to reason about privacy for each user under different contexts. At runtime, these arguments provide a way to reason about requirements satisfaction and diagnosis. Our proposed approach is demonstrated and evaluated using the privacy requirements of BuddyTracker, a mobile application we developed as part of our overall research programme.

“…In requirements elicitation, the end-user is often described as the primary source for identifying needs [2], [10] Researchers highlight the fact that end-user involvement improves the quality of requirements [2], [8], [12], [27] and that it varies in different requirements elicitation activities [22], [23], [28]. There exists a broad range of elicitation techniques such as brainstorming, interviews, workshops, and scenarios [29], [30], [31], [32] where end-users play an important role.…”

“…There exists a broad range of elicitation techniques such as brainstorming, interviews, workshops, and scenarios [29], [30], [31], [32] where end-users play an important role. However, most of these approaches focus on elicitation activities facilitated by requirements analysts who also document upcoming user requirements [22], [28], [33]. Researchers often describe end-user participation in requirements elicitation as informative [2], [7], this suggests a passive role for the end-user.…”

Abstract-Researchers highlight end-user involvement in system design as an important concept for developing useful and usable solutions. However, end-user involvement in software engineering is still an open-ended topic. Novel paradigms such as service-oriented computing strengthen the need for more active end-user involvement in order to provide systems that are tailored to individual end-user needs. Our work is based on the fact that the majority of end-users are familiar with mobile devices and use an increasing number of mobile applications. A mobile tool enabling end-user led requirements elicitation could be just one of many applications installed on end-users' mobile devices. In this paper, we present a framework of end-user involvement in requirements elicitation which motivates our research. The main contribution of our research is a tool-supported requirements elicitation approach allowing end-users to document needs in situ. Furthermore, we present first evaluation results to highlight the feasibility of on-site end-user led requirements elicitation.

“…Neste contexto, algumas técnicas de criatividade como Cenários [9], Workshops [10], Design Thinking [11] e Criatividade Combinacional [4,12] têm sido usadas para incitar os stakeholders a produzirem requisitos criativos. Em relação a criatividade combinacional, podemos citar o framework definido em [4], que propõe a criação de requisitos através da combinação de palavras extraídas de uma rede social por meio de algoritmos de Processamento de Linguagem Natural (PLN), Análise de Rede Social e Análise de Similaridade.…”

Resumo:Diante da crescente competitividade do mercado, a Engenharia de Requisitos tem buscado, através de técnicas de criatividade, fornecer meios para elicitação de requisitos úteis e inovadores. Dentre estas técnicas há a criatividade combinacional, que possibilita a produção de novas ideias através da combinação de ideias antigas não familiares. Trabalhos nesta linha têm demonstrado bons resultados, mas poucos comparam esta técnica com outras. Assim, o objetivo deste trabalho é comparar os resultados alcançados na elicitação usando e não usando uma abordagem combinacional. A elicitação teve a participação de 17 usuários assíduos de um sistema acadêmico, dos quais 9 utilizaram a abordagem combinacional e 8 uma abordagem baseada em entrevista. A elicitação foi realizada numa reunião, na qual os participantes criaram, individualmente, 42 requisitos válidos, 21 por cada técnica. Destes, apenas 9 foram avaliados como úteis e originais. Em termos quantitativos, não houve grande diferença na quantidade de requisitos ao mesmo tempo úteis e originais que foram gerados pelas duas técnicas. Entretanto, mais requisitos úteis foram gerados com a técnica de entrevista. Em termos qualitativos, os participantes sugeriram que uma abordagem mista facilitaria a elaboração de ideias inovadoras.Palavras-chave: Criatividade Combinacional, Elicitação de Requisitos, Entrevista, Estudo Empí-rico. Abstract:Faced with the market's growing competitiveness, Requirements Engineering has sought, through creativity techniques, to provide means to elicit useful and innovative requirements. Among these techniques, there is the combinational creativity, which allows the development of new ideas through the combination of non-familiar old ideas. Works that follow this technique have shown good results, but only a few of them compare this technique to others. Thus, the goal of this work is to compare the results achieved in elicitation using and not using a combinational approach. The elicitation process had, as participants, 17 regular users of an academic system, 9 of which used the combinational approach while the remaining 8 used an interview-based approach. The elicitation was carried out in a meeting, in which the participants individually created 42 valid requirements, 21 for each technique. Out of the requirements that were created, only 9 were considered useful and original. In quantitative terms, there was not much difference in the number of requirements that were both original and useful generated by each of the two techniques. However, a greater number of useful requirements were generated using the interview technique. In qualitative terms, participants suggested that to use a mixed approach would favor the creativity.
