Artificial Intelligence (AI), and especially machine learning can be used to find statistical patterns in datasets with thousands of variables with ease. But an understanding of causality is difficult to learn for a machine. For humans however, realising causal relations is often not a difficult process, as we can refer to experience or scientific...

In order to increase the ability to build complex, software-intensive systems, as well as to decrease time-to-market for new functionality, automotive companies aim to scale agile methods beyond individual teams. This is challenging, given the specifics of automotive systems that are often safety-critical and consist of software, hardware, and mech...

[Context and motivation] For automated driving systems, the operational context needs to be known in order to state guarantees on performance and safety. The operational design domain (ODD) is an abstraction of the operational context, and its definition is an integral part of the system development process. [Question / problem] There are still maj...

Context and motivation] Good quality of data is crucial for effective and safe operation of any system. For safety critical systems such as automated driving, the significance of data quality is even higher since wrong or low-quality data may cause fatal faults. [Ques-tion / problem] However, there are challenges in identifying and managing data qu...

Practitioners are poorly supported by the scientific literature when managing traceability information models (TIMs), which capture the structure and semantics of trace links. In practice, companies manage their TIMs in very different ways, even in cases where companies share many similarities. We present our findings from an in-depth focus group a...

Distributed software development is more difficult than co-located software development. One of the main reasons is that communication is more difficult in distributed settings. Defined processes and artifacts help, but cannot cover all information needs. Not communicating important project information, decisions and rationales can result in duplic...

Large-scale system development companies are increasingly adopting agile methods. While this adoption may improve lead-times, such companies need to balance two trade-offs: (i) the need to have a uniform, consistent development method on system level with the need for specialised methods for teams in different disciplines(e.g., hardware, software,...

Several studies report that the use of model-centric methods in the automotive domain is widespread and offers several benefits. However, existing work indicates that few modelling frameworks explicitly include requirements engineering (RE), and that natural language descriptions are still the status quo in RE. Therefore, we aim to increase the und...

Preprint
In the last decades, agile methods had a huge impact on how software is developed. In many cases, this has led to significant benefits, such as quality and speed of software deliveries to customers. However, safety-critical systems have widely been dismissed from benefiting from agile methods. Products that include safety critical aspects are there...

APIs provide value beyond technical functionality. They enable and manage access to strategic business assets and play a key role in enabling software ecosystems. Existing work has begun to consider the strategic business value of software APIs, but such work has limited analysis capabilities and has not made use of established, structured modeling...
Conference Paper
Most of the innovation in automotive is nowadays coming from electronics and software. The pressure of reducing time to market and increasing flexibility while keeping quality are leading motivations for these companies to embrace system-wide Continuous Integration and Delivery (CI&D), which in the scope of complex automotive value-chains, implies...
Conference Paper
Automotive companies increasingly include proven agile methods in their plan-driven system development. The adoption of agile methods impacts not only the way individuals collaborate, but also the management of artifacts like requirements, test cases, safety documentation, and models.
