This issue of the Software Quality Journal is devoted to studies on the quality of software in various advanced applications in business, industry, and everyday life. Following an open call and a thorough review process, the articles accepted for publication cover various aspects relevant to the generic topic. Various areas are represented in the published papers, such as embedded systems, gap analysis, component-based software engineering, open source software analysis, software management, bug reports, and domain-specific modeling. Moreover, different qualitative and quantitative methodologies are used such as empirical studies, questionnaires, prioritization techniques, statistical analysis, software repositories mining, recommendation systems, text analysis, and systematic literature mapping. This issue consists of 7 papers that are briefly discussed as follows: The article by D. Sas and P. Avgeriou entitled “Quality attribute trade-offs in the embedded systems industry An exploratory case study” deals with challenges in the embedded systems industry and specifically with the study of practices, processes, and tools concerning the management of run-time and design-time quality attributes as well as the trade-offs among them from the perspective of embedded systems software engineers. The authors use qualitative data from interviews and a focus group session with participants from six different companies and their analysis reveals interesting preferences, practices, difficulties, and risks related to software qualities and their trade-offs, along with needs for automated tools. In “A Model Driven Engineering approach for supporting Questionnaire-Based Gap Analysis Processes through Application Lifecycle Management Systems” by D. Amalfitano, V. De Simone, S. Scala, and A. R. Fasolino, the authors deal with questionnaire-based gap analysis, a process for evaluating the gaps between implemented software and quality requirements through questionnaires. The paper proposes the utilization of application lifecycle management Software Quality Journal https://doi.org/10.1007/s11219-020-09497-z
