The goal of Digital Transformation of the Public Sector is the achievement of a better quality of life for citizens, via a more responsive and transparent administration and governance. By now it is clear that technological innovation, both in terms of computer architectures and software systems, is a crucial component of it, yet not sufficient. Indeed, a cultural, organizational and legal shift in how public organizations operate and relate to the citizens is also required. Nevertheless, computer scientists can play a key role in such a transformation and, given its impact on Society, it is essential to achieve a broader level of awareness of it and involvement in it of those scientific and professional figures. To this end, a technical map specifically designed for computer scientists, but properly placed in the context of the cultural, organizational and legal changes mentioned above, would be highly beneficial. To date, such a map is missing, to the best of our knowledge. The main contribution of this Tutorial is to provide it, together with a guided tour describing which key technological aspects enable and drive such a transformation. More specifically, based on a careful analysis of the available scholarly literature, that does not seem to include any Computer Science textbook material, a model of such a transformation is proposed, together with carefully selected examples incarnating it to show its validity: the cities of Barcelona and Chicago. Finally, a look at the future of this area is also provided.

Digital transformation in the public sector provides digital services to the citizens aiming at increasing their quality of life, as well as the transparency and accountability of a public administration. Since adaptation to the citizens changing needs is central for its success, Agile methodologies seem best suited for the software development of digital services in that area. However, as well documented by an attempt to use Scrum for an important Public Administration in Italy, substantial modifications to standard Agile were needed, giving rise to a new proposal called improved Agile (in short, iAgile). Another notable example is the Scrum@IMI method developed by the City of Barcelona for the deployment of its digital services. However, given the importance of digital transformation in the public sector and the scarcity of efforts (documented in the scholarly literature) to effectively bring Agile within it, a strategically important contribution that Computer Science can offer is a general paradigm describing how to tailor Agile methodologies and, in particular, Scrum, for such a specific context. Our proposal, called Scrum@PA, addresses this strategic need. Based on it, a public administration has a technically sound avenue to follow to adopt Scrum rather than a generic set of guidelines as in the current state of the art. We show the validity of our proposal by describing how the quite successful Scrum@IMI approach can be derived from Scrum@PA. Although iAgile can also be derived from our paradigm, we have chosen Scrum@IMI as a pilot example since it is publicly available on GitHub.

Several research works propose non-textual alternatives to textual documentation and similar forms of representing information in software development. This is because of the problems that stem from writing these documents, which range from incomprehensible requirements to ambiguous user stories. The various proposals of researchers often contain some trace of oral or visual communication. In this paper, we study the implications of eliminating textual communication and substituting unnecessary writing by extracting the values of West African oral storytellers. Traditional West African communities did not make use of writing for thousands of years and yet their legends, customs, beliefs, and knowledge were effectively transmitted across several generations. How did they manage to accomplish this? What can we learn from their storytellers? How can these lessons be applied to software products? These are all questions that this paper attempts to answer. Perhaps if we fully understand how they operated, then we can target our written communication to the activities where it is needed instead of spreading writing across plenty of tasks as it is currently. To achieve this, we performed an analysis of the two domains: West African oral storytelling and software development and found similarities, then selected some key elements from oral storytelling and explained how they can have relevance in software development. The theme directly encompasses diversity and inclusion by bringing into software engineering a perspective of a region where its literacy research is scarcely being explored. The study found that traditional oral storytelling can provide insights into effective communication and audience engagement, and identified four ways in which software development can be compared to oral storytelling. The study also found that certain elements of storytelling, such as audience relationship, story structure, parables and proverbs, and community relaxation and support, can be applied to writing tasks in software development.

Over the past 20 years agile methodologies revolutionized Information Technology, offering tremendous opportunities for the development of Software Engineering as an independent discipline. More specifically, agile methodologies contributed to enhancing the effectiveness and the speed of the production process as well as to improving the productivity and motivations of software developers organized in high performing teams. The agile philosophy can be and has been applied in different contexts and across several domains. This work analyses the relationship between Agile methodologies used by software engineers and the practices pursued by musicians in their daily lives. Our findings suggests that collaborative, strongly planned software development life cycle models (such as Waterfall, V-model, iterative, and Spiral) are not adequate models to describe the daily practices of musical composers. This is because their work requires a lot of flexibility, which such models intrinsically lack, because they are oriented to ensuring some form of monitorable progress. Interestingly, our findings also show that nine out of 12 Agile Principles are consciously or unconsciously followed by musicians in their practices. This suggests that there are some deep connections between these two prima facie different fields, which are both very creative. Even though our findings await replication, possibly with larger statistical samples, they contribute to open up a new strand of research in the field.

IntroductionModern Code Review (MCR) is a multistage process where developers evaluate source code written by others to enhance the software quality. Despite the numerous studies conducted on the effects of MCR on software quality, the non-technical issues in the MCR process have not been extensively studied. This study aims to investigate the social problems in the MCR process and to find possible ways to prevent them and improve the overall quality of the MCR process.MethodologyTo achieve the research objectives, we applied the grounded theory research shaped by GQM approach to collect data on the attitudes of developers from different teams toward MCR. We conducted interviews with 25 software developers from 13 companies to obtain the information necessary to investigate how social interactions affect the code reviewing process.ResultsOur findings show that interpersonal relationships within the team can have significant consequences on the MCR process. We also received a list of possible strategies to overcome these problems.DiscussionOur study provides a new perspective on the non-technical issues in the MCR process, which has not been extensively studied before. The findings of this study can help software development teams to address the social problems in the MCR process and improve the overall quality of their software products.ConclusionThis study provides valuable insights into the non-technical issues in the MCR process and the possible ways to prevent them. The findings of this study can help software development teams to improve the MCR process and the quality of their software products. Future research could explore the effectiveness of the identified strategies in addressing the social problems in the MCR process.

Communication among humans consists of both verbal and non verbal components. The latter may sometimes express concepts or ideas not conveyable by the former. This is also true in Software Engineering. This paper first analyses theoretically the role of non verbal communication in software development teams, using the framework provided by distributed cognition as a conceptual palette and as a point of reference. Then, it presents an empirical investigation involving 38 IT professionals from Russia, sharing their experiences in communicating and interacting when developing software artifacts. The results of this empirical investigation are consistent with many of the ideas underlying a distributed approach to cognition. In addition, our findings provide valuable insights to make communication more effective in software development teams, while defining a new framework for follow-up studies.

Background The 2010 reform of the Italian university system introduced the National Scientific Habilitation (ASN) as a requirement for applying to permanent professor positions. Since the CVs of the 59,149 candidates and the results of their assessments have been made publicly available, the ASN constitutes an opportunity to perform analyses about a nation-wide evaluation process. Objective The main goals of this paper are: (i) predicting the ASN results using the information contained in the candidates’ CVs; (ii) identifying a small set of quantitative indicators that can be used to perform accurate predictions. Approach Semantic technologies are used to extract, systematize and enrich the information contained in the applicants’ CVs, and machine learning methods are used to predict the ASN results and to identify a subset of relevant predictors. Results For predicting the success in the role of associate professor, our best models using all and the top 15 predictors make accurate predictions (F-measure values higher than 0.6) in 88% and 88.6% of the cases, respectively. Similar results have been achieved for the role of full professor. Evaluation The proposed approach outperforms the other models developed to predict the results of researchers’ evaluation procedures. Conclusions Such results allow the development of an automated system for supporting both candidates and committees in the future ASN sessions and other scholars’ evaluation procedures.

The European Computer Driving Licence (ECDL) programme aims at testing practical skills and competences in using ICT tools. This paper presents the results of a monitoring exercise aimed at analyzing the impact of the ECDL programme in the Italian Universities. The ECDL programme, adopted in most Italian Universities since the year 2000, has involved several tens of thousands of students. Our investigation focused on the experiences of the Universities in the year 2003 and, in particular, on the organizational and teaching issues addressed for the implementation of the programme. The analysis has shown that the implementation relied on a large variety of choices about what concerns the teaching organization, the credits awarded to the students and the type of ECDL certification required. These choices varied as a function of the size of the Universities, whereas their geographical location did not seem to have any influence.
