- As sustainability increasingly gains attention, it has also found its way into the area of software engineering, with a specific emphasis on requirements engineering. The Sustainability Awareness Framework (SusAF) proposed by Duboc et al. supports stakeholders in taking the long view at their software systems in terms of sustainability. In this paper, we propose SusApp, a web-based tool to simplify the application of the SusAF. In particular, it facilitates the documentation and visualization of effects on sustainability. To learn about the users' perception of SusApp, we conducted two small-scale user studies that investigated the tool's usability and usefulness. Overall, the studies showed that the tool was generally perceived positively by the participants. However, shortcomings in the usability became apparent, which have also impacted the perceived usefulness.

Prototyping Practices in Software Startups : Initial Case Study Results
- 2021
-
Ingår i: Proceedings - 29th IEEE International Requirements Engineering Conference Workshops, REW 2021. - 2332-6441 .- 1090-705X. - 9781665418980 ; 2021-September, s. 206-211

Konferensbidrag (refereegranskat)abstract
- Software startups use prototyping to develop and test business ideas and to validate market viability. While prototyping is emphasized in agile methods, there is little research on how startups can best utilise scarce resources to effectively use prototypes in their dynamic business context. We performed a case study of four startups and investigated how startups currently use prototyping to elicit, validate and communicate requirements through semi-structured interviews. Our initial results indicate that prototyping is a commonly applied practice that is implicitly required to obtain funding for early stage startups, that software engineering competence is required to produce interactive and fully functioning prototypes, and that it is a challenge to balance prototype scope against expected gains.

Welcome to the First International Workshop on Requirements Engineering for Explainable Systems (RE4ES)
- 2021

- Welcome to the First International Workshop on Requirements Engineering for Explainable Systems (RE4ES), where we aim to advance requirements engineering (RE) for explainable systems, foster interdisciplinary exchange, and build a community. On the one hand, we believe that the methods and techniques of the RE community can add much value to explainability research. On the other hand, we have to ensure that we develop techniques fitted to the needs of other communities.This first workshop explores synergies between the RE community and other communities already researching explainability.To this end, we have based our agenda on a mix of paper presentations from authors of different domains, one keynote from industry and one from research, as well as interactive activities to stimulate lively discussions.

D-REQs: Determination of security safety requirements in workshops based on the use of model-based systems engineering
- 2021

Konferensbidrag (refereegranskat)abstract
- Cyber-physical systems, like autonomous vehicles, are intelligent and networked. The development of such systems requires cooperation between different stakeholders. A lack of system understanding can lead to unidentified (safety relevant) security requirements (SRSR) in early engineering. This can increase product development costs or compromise system safety compliance. Model-based systems engineering (MBSE) improves the system understanding by using models. Conducting workshops in the context of MBSE promotes interaction between stakeholders so that confusion regarding SRSR can be resolved already in the workshop. Using the models created, requirements can be derived in the workshop. However, established security safety approaches are not specifically designed to be used in conjunction with MBSE and requirements engineering. In this paper, we present an extension of our previously developed SAVE approach. This extension supports a team of stakeholders in workshops to derive SRSR using MBSE. We illustrate our approach with an example from the automotive domain and present an initial field study of the application of our approach, based on a 2-month student project.

Design Decisions in the Construction of Traceability Information Models for Safe Automotive Systems
- 2021

Konferensbidrag (refereegranskat)abstract
- Traceability management relies on a supporting model, the traceability information model (TIM), that defines which types of relationships exist between which artifacts and contains additional constraints such as multiplicities. Constructing a TIM that is fit for purpose is crucial to ensure that a traceability strategy yields the desired benefits. However, which design decisions are critical in the construction of TIMs and which impact they have on the usefulness and applicability of traceability is still an open question. In this paper, we use two cases of TIMs constructed for safety-critical, automotive systems with industrial safety experts, to identify key design decisions. We also propose a comparison scheme for TIMs based on a systematic literature review and evaluate the two cases as well as TIMs from the literature according to the scheme. Based on our analyses, we thus derive key insights into TIM construction and the design decisions that ensure that a TIM is fit for purpose.

The MobSTr Dataset - An Exemplar for Traceability and Model-based Safety Assessment
- 2021
-
Ingår i: Proceedings of the IEEE International Conference on Requirements Engineering. - 2332-6441 .- 1090-705X. ; RE 2021, s. 444-445

Konferensbidrag (refereegranskat)abstract
- The MobSTr dataset contains a number of artifacts for an autonomous driver assistance system, ranging from textual requirements to models for system design and models relevant to safety assurance. The artifacts provided are connected with traceability links created and managed with Eclipse Capra, an open source traceability management tool. The dataset builds upon a custom traceability information model that provides type safety and semantics for the trace links.MobSTr is intended for researchers that work on software and systems traceability as well as on model-based safety assurance. It is already being used in a number of studies, including research on trace link consistency, change impact analysis, and automated analysis of safety and timing requirements.
