After a successful 7 th QuASoQ workshop we slightly adjusted the list of topics for the workshop. The topics of interest included • New approaches to measurement, evaluation, comparison and improvement of software quality proaches in agile projects • Case studies and industrial experience reports on successful or failed application of quantitative approach-es to software quality ing quantitative approaches measurement techniques and models • Quantitative approaches to test process improvement, test strategies or testability • Empirical evaluations or comparisons of testing techniques in industrial settings
Overall, the workshop aimed at gathering together researchers and practitioners to discuss experiences in the application of state of the art approaches to measure, assess and evaluate the quality of both software systems as well as software development processes in general and software test processes in particular.

Workshop Proceedings (CEUR-WS.org) quality specification and quality assurance are crucial. Although there are lots of approaches to deal with quantitative quality aspects, it is still challenging to choose a suitable set of techniques that best fit to the specific project and organizational constraints.
Even though approaches, methods, and techniques are known for quite some time now, little efort has been spent on the exchange on the real-world problems with search has been devoted to empirically evaluate risks, eficiency or limitations of diferent testing techniques in industrial settings.
Hence, one main goal of the workshop was to exchange discuss how to set up, organize, and maintain quantitative 2.

Because of the covid-19 pandemic, the workshop was executed digitally using the video conferencing tool Zoom.
Based on our former experience we wanted the workshop to be highly interactive. In order to have an interesting and interactive event sharing lots of experience, we organized the workshop presentations applying the author-discussant model.
Based on this workshop model, papers are presented by one of the authors. After the presentation, a discussant starts the discussion based on his or her pre-formulated questions. Therefore, the discussant had to prepare a set of questions and had to know the details of the presented paper. The general structure of each talk was as follows: • The author of a paper presented the paper (15 minutes). • After that, the discussant of the paper opened the discussion using his or her questions. Finally, we moderated the discussion among the whole audience (5 minutes).
Altogether 12 papers were submitted. Finally, the following 10 papers were accepted by the program committee for presentation and publication covering very diferent topics.

Many people contributed to the success of this workshop. First, we want to give thanks to the authors and presenters of the accepted papers. Furthermore, we want to express our gratitude to the APSEC 2020 organizers; they did a perfect job and gave us the freedom to conduct the workshop virtually based on our experience.
Finally, we are glad that these people served on the
