“…Moody and his colleagues [75], [76] filled the gap by proposing a set of principles for cognitively effective visual notations [74], including semiotic clarity, perceptual discriminability, and graphic economy. While a recent empirical study [13] on i * shows that the visual notations designed by following the principles are more semantically transparent than those originally proposed [126], the work is in line with the REV theme of striving for the best set of static notations. Our focus, in contrast, is on creating dynamic visualizations to support analytics.…”

For many software projects, keeping requirements on track needs an effective and efficient path from data to decision. Visual analytics creates such a path that enables the human to extract insights by interacting with the relevant information. While various requirements visualization techniques exist, few have produced end-to-end values to practitioners. In this dissertation, we advance the literature on visual requirements analytics by characterizing its key components and relationships in a framework. We follow the goal-question-metric paradigm to define the framework by teasing out five conceptual goals (user, data, model, visualization, and knowledge), their specific operationalizations, and their interconnections. The framework allows us to not only assess existing approaches, but also create tool enhancements in a principled manner.We evaluate our enhanced tool supports both qualitatively and quantitatively. First, we evaluate our tool supports qualitatively through a case study where massive, heterogeneous, and dynamic requirements are processed, visualized, and analyzed. Working together with practitioners on a contemporary software project within its real-life context leads to the main ending that visual analytics can help tackle both open-ended visual exploration tasks and well-structured visual exploitation tasks in requirements engineering. In addition, the study helps the practitioners to reach actionable decisions in a wide range of areas relating to their project, ranging from theme and outlier identification, over requirements tracing, to risk assessment. Overall our work illuminates how the data-to-decision analytical capabilities could be improved by the increased interactivity of requirements visualization.Although many new visual analytics tools, techniques and methods are being developed, still there is a lack of understanding of how to evaluate the performance of such tools. We conducted an experiment to assess the performance (time and correctness) of our visual analytics tool support in solving requirements engineering tasks. Our study provides initial evidence and insights for visual analytics in requirements engineering and sheds light on many challenging open questions.

Abstract. Graphical notations designed by committees in the context of standardization bodies, like Object Management Group (OMG), are widely used in the industry and academia. Naive users of these notations have limited background on visualization, documentation and specification of workflows, data or software systems. Several studies have pointed out the fact that these notations do not convey any particular semantics and their understanding is not perceptually immediate. As reported in these studies, this lack of semantic transparency increases the cognitive load to differentiate between concepts, slows down the learning and comprehension of the language constructs. This paper reports on a set of experiments that confirm the lack of semantic transparency of the Unified Modeling Language (UML) as designed by OMG and compares this standard to alternative solutions where naive users are involved in the design of the notations to speed-up the learning of these languages to new users.

Summary Cybersecurity compliance analysis is the process of assessing whether the behavior of an IT system or application conforms to the cybersecurity rules and regulations in force. This assessment can be offered as a service by exploiting available cloud technologies, and, indeed, it is one of the services classified by the Cloud Security Alliance (CSA) as part of the security information and event management (SIEM) category of the SecaaS (security as a service) domain. The definition and implementation of this typology of cloud services are challenging activities due to the complexity of both the reference business domain and the compliance analysis services to be provided themselves. The paper exploits a recently proposed requirements methodology, called GOReM (goal‐oriented requirements methodology), to support the conceptualization and subsequent implementation of cybersecurity compliance analysis services. In particular, two different application scenarios regarding compliance analysis of an existing or under development IT system/application are presented and discussed. In both the scenarios, GOReM allows to grasp and understand the many and complex issues to address for providing secure cloud services to worldwide customers, also due to the numerous, different and ever changing legal aspects, which have to be taken into account by service providers.
