Over the years, many methods and techniques have been proposed to improve their elicitation, documentation, and validation. Knowing more about the state of the practice on these topics may benefit both practitioners' and researchers' daily work. A few empirical studies have been conducted in the past, but none under the perspective of software architects, in spite of the great influence that NFRs have on daily architects' practices. This paper presents some of the findings of an empirical study based on 13 interviews with software architects. It addresses questions such as: who decides the NFRs, what types of NFRs matter to architects, how are NFRs documented, and how are NFRs validated. The results are contextualized with existing previous work.Peer ReviewedPostprint (author’s final draft
Non-functional requirements in software architecture practice
Dealing with non-functional requirements (NFRs) has posed a challenge onto software engineers for many years.

Understanding the Curriculum Gap in Systems Analysis and Design: An Exploratory Study
This research in progress describes an exploratory study that investigates the Systems Analysis and Design (SA&D) skills, knowledge, and practices that are considered most important by industry practitioners and compares with the course content, skills, and coverage in a typical undergraduate SA&D course. We present preliminary results and analysis of semi-structured interviews conducted with industry practitioners and outline the next steps. We believe that the final findings of this study should lead to a better understanding of the gap between what is currently taught in a typical SA&D course and what is considered as important by practitioners. It should assist educators in structuring their SA&D course to be more aligned with the contemporary needs of the industry
Paving the Roadway for Safety of Automated Vehicles: An Empirical Study on Testing Challenges
The technology in the area of automated vehicles is gaining speed and
promises many advantages. However, with the recent introduction of
conditionally automated driving, we have also seen accidents. Test protocols
for both, conditionally automated (e.g., on highways) and automated vehicles do
not exist yet and leave researchers and practitioners with different
challenges. For instance, current test procedures do not suffice for fully
automated vehicles, which are supposed to be completely in charge for the
driving task and have no driver as a back up. This paper presents current
challenges of testing the functionality and safety of automated vehicles
derived from conducting focus groups and interviews with 26 participants from
five countries having a background related to testing automotive safety-related
topics.We provide an overview of the state-of-practice of testing active safety
features as well as challenges that needs to be addressed in the future to
ensure safety for automated vehicles. The major challenges identified through
the interviews and focus groups, enriched by literature on this topic are
related to 1) virtual testing and simulation, 2) safety, reliability, and
quality, 3) sensors and sensor models, 4) required scenario complexity and
amount of test cases, and 5) handover of responsibility between the driver and
the vehicle.Comment: 8 page
