Requirements specifcation is a core activity in the requirements engineering phase of a software development project. Researchers have contributed extensively to the feld of requirements specifcation, but the extent to which their proposals have been adopted in practice remains unclear. We gathered evidence about the state of practice in requirements specifcation by focussing on the artefacts used in this activity, the application of templates or guidelines, how requirements are structured in the specifcation document, what tools practitioners use to specify requirements, and what challenges they face. We conducted an interview-based survey study involving 24 practitioners from 12 diferent Swedish IT companies. We recorded the interviews and analysed these recordings, primarily by using qualitative methods. Natural language constitutes the main specifcation artefact but is usually accompanied by some other type of instrument. Most requirements specifcations use templates or guidelines, although they seldom follow any fxed standard. Requirements are always structured in the document according to the main functionalities of the system or to project areas or system parts. Diferent types of tools, including MS Ofce tools, are used, either individually or combined, in the compilation of requirements specifcations. We also note that challenges related to the use of natural language (dealing with ambiguity, inconsistency, and incompleteness) are the most frequent challenges that practitioners face in the compilation of requirements specifcations. These fndings are contextualized in terms of demographic factors related to the individual interviewees, the organization they are afliated with, and the project they selected to discuss during our interviews. A number of our fndings have been previously reported in related studies. These fndings show that, in spite of the large number of notations, models and tools proposed from academia for improving requirements specifcation, p, This paper has been funded by the Spanish Ministerio de Ciencia e Innovación under project/funding scheme PID2020-117191RB-I00/AEI/., Peer Reviewed, Postprint (published version)

En el contexto de las carreras universitarias donde se estudia cine y audiovisuales, los estudiantes deben realizar varios proyectos de cine, cortometrajes y videos en cada uno de los años de la carrera universitaria de audiovisuales. Cada uno de estos proyectos requieren tanto de recursos humanos principalmente: productores, técnicos de sonido, jefes de producción, guionistas, directores de fotografía, directores de arte, figurantes, foquista, runners y otras muchas profesiones, como también requieren de recursos materiales tales como: cámaras, micrófonos, focos de iluminación grúas-dolly y materiales técnicos en general. Aunque en muchos casos, los participantes en los proyectos son compañeros de curso, a medida que avanzan los estudios y los proyectos tienen mayor complejidad, no hay suficientes compañeros para cubrir las necesidades de recursos humanos para dichos proyectos. En estas situaciones, los estudiantes de estas carreras universitarias suelen valerse de los folletos colocados en tablas de anuncios de sus residencias universitarias o de sus centros educativos, otros recurren a poner anuncios en sus redes sociales con la esperanza de que personas conocidas de sus amigos o familiares puedan estar interesados. En lo que respecta a los recursos materiales, los equipos técnicos y otros materiales que se utilizan en los proyectos pueden costar cientos o miles de euros, lo que hace que muchos estudiantes no se puedan permitir comprar estos materiales. Por otra parte, otros estudiantes sí tienen posibilidades de comprar el material audiovisual, y en muchas ocasiones, para recuperar parte o la totalidad de su inversión, alquilan sus equipos. Para entrar en contacto unos y otros se hace actualmente a través de contactos de amigos, cosa que dificulta en muchos casos que estudiantes que buscan alquilar material entren en contacto con estudiantes dispuestos a alquilar su material.

Best Paper Award a l’Experimental Software Engineering Track (ESELAW) de la XXIV Ibero-American Conference on Software Engineering, CIbSE 2021, Context: Tertiary studies are becoming increasingly popular in software engineering as an instrument to synthesise evidence on a research topic in a systematic way. In order to understand and contextualize their findings, it is important to assess the quality of the selected secondary studies. Objective: This paper aims to provide a state of the art on the assessment of secondary studies’ quality as conducted in tertiary studies in the area of software engineering, reporting the frameworks used as instruments, the facets examined in these frameworks, and the purposes of the quality assessment. Method: We designed this study as a systematic mapping responding to four research questions derived from the objective above. We applied a rigorous search protocol over the Scopus digital library, resulting in 47 papers after application of inclusion and exclusion criteria. The extracted data was synthesised using content analysis. Results: A majority of tertiary studies perform quality assessment. It is not often used for excluding studies, but to support some kind of investigation. The DARE quality assessment framework is the most frequently used, with customizations in some cases to cover missing facets. We outline the first steps towards building a new framework to address the shortcomings identified. Conclusion: This paper is a step forward establishing a foundation for researchers in two different ways. As authors of tertiary studies, understanding the different possibilities in which they can perform quality assessment of secondary studies. As readers, having an instrument to understand the methodological rigor upon which tertiary studies may claim their findings., Peer Reviewed, Award-winning, Postprint (author's final draft)

La realització i implementació d'un programa de gestió acadèmica i administrativa per a un centre universitari va tenir com a objectiu organitzar les dades que el centre tenia enregistrades en diversos fulls de Microsoft Excel inconnexos entre ells. La primera fase del projecte va consistir en analitzar la informació existent i crear una base de dades relacional que facilités la introducció, consulta, impressió i, sobretot, l'anàlisi i resum de la informació per un control administratiu i acadèmic eficient. Posteriorment, es va desenvolupar el codi i la interfície d'usuari per a que l'aplicació fos intuïtiva, fiable, segura i multiusuari. Durant tot el procés de codificació, s'ha tingut en compte els requisits específics del centre tant amb les dades com en els procediments que hi havia implementats per tal que la transició del personal del centre a la nova aplicació fos el més ràpid i eficaç possible al mateix temps que es pogués aprofitar, al màxim, la feina feta en els fulls de càlcul. Tots els processos s'han testejat fins a l'últim detall i el resultat ha estat una aplicació de gestió completa i adaptada a les necessitats del centre universitari, de fàcil utilització i d'una gran seguretat en la integració de les dades., The main objective of the development and implementation of an academic and administrative management program for a university centre, was to organise the data that the centre had stored in various unconnected Microsoft Excel spreadsheets. The first part of the project was to analyse the existing information and create a relational database that would facilitate the entry, querying, printing and, above all, the analysis and summary of the information for an efficient administrative and academic control. Afterwards, the code and user interface were developed to make the application intuitive, reliable, safe and multi-user. Throughout the coding process, the specific requirements of the centre were considered with both the data and the procedures already in place to make the transition of staff to the new application faster and more efficient, while at the same time take advantage of the work done in the spreadsheets. All processes have been tested and checked down to the last detail and the result has been a complete application adapted to the needs of the university centre, easy to use and with a great security in the integration of the data.

Context: Tertiary studies in software engineering (TS@SE) are widely used to synthesise evidence on a research topic systematically. As part of their protocol, TS@SE define inclusion and exclusion criteria (IC/EC) aimed at selecting those secondary studies (SS) to be included in the analysis. Aims: To provide a state of the art on the definition and application of IC/EC in TS@SE, and from the results of this analysis, we outline an emerging framework, TSICEC, to be used by SE researchers. Method: To provide the state of the art, we conducted a systematic mapping (SM) combining automatic search and snowballing over the body of SE scientific literature, which led to 50 papers after application of our own IC/EC. The extracted data was synthesised using content analysis. The results were used to define a first version of TSICEC. Results: The SM resulted in a coding schema, and a thorough analysis of the selected papers on the basis of this coding. Our TSICEC framework includes guidelines for the definition of IC/EC in TS@SE. Conclusion: This paper is a step forward establishing a foundation for researchers in two ways. As authors, understanding the different possibilities to define IC/EC and apply them to select SS. As readers, having an instrument to understand the methodological rigor upon which TS@SE may claim their findings., This work has been partially supported by the DOGO4ML Spanish research project (ref.

Requirements engineering remains a discipline that is faced with a large number of challenges, including the implementation of a requirements elicitation process in industry. Although several proposals have been suggested by researchers and academics, little is known of the practices that are actually followed in industry. Our objective is to investigate the state-of-practice with respect to requirements elicitation, by closely examining practitioners’ current practices. To this aim, we focus on the techniques that are used in industry, the roles that requirements elicitation involves, and the challenges that the requirements elicitation process is faced with. As method, we conducted an interview-based survey study involving 24 practitioners from 12 different Swedish IT companies, and we recorded the interviews and analyzed these recordings by using quantitative and qualitative methods. Several results emerged from the studies. Group interaction techniques, including meetings and workshops, are the most popular type of elicitation techniques that are employed by the practitioners, except in the case of small projects. Additionally, practitioners tend to use a variety of elicitation techniques in each project. We noted that customers are frequently involved in the elicitation process, except in the case of market-driven organizations. Technical staff (for example, developers and architects) are more frequently involved in the elicitation process compared to the involvement of business or strategic staff. Finally, we identified a number of challenges with respect to stakeholders. These challenges include difficulties in understanding and prioritizing their needs. Further, it was noted that requirements instability (i.e., caused by changing needs or priorities) was a predominant challenge. These observations need to be interpreted in the context of the study. We conclude that the relevant observations regarding the survey participants’ experiences should be of interest, This work has been supported by the GENESIS project, funded by the Spanish Ministerio de Ciencia e Innovación under project TIN2016-79269-R, and the Horizon 2020 project OpenReq, supported by the European Union under Grant Nr. 732463., Peer Reviewed, Postprint (author's final draft)
