Over the past decade, a dramatic increase of functionality, quantity, size, and complexity of software-intensive embedded systems in the automotive industry can be observed. In particular, the growing complexity drives current requirements engineering practices to the limits. In close cooperation between partners from industry and academia, the recently(More)
Trustworthiness of Internet-based software systems, apps, services and platform is a key success factor for their use and acceptance by organizations and end-users. The notion of trustworthiness, though, is subject to individual interpretation and preference, e.g., organizations require confidence about how their business critical data is handled whereas(More)
The analysis of existing software evaluation techniques reveals the need for evidence-based evaluation of systems' trustworthiness. This paper aims at evaluating trustworthiness of socio-technical systems during design-time. Our approach combines two existing evaluation techniques: a computational approach and a risk management approach. The risk-based(More)
Trustworthiness of dynamical and distributed socio-technical systems is a key factor for the success and wide adoption of these systems in digital businesses. Different trustworthiness attributes should be identified and accounted for when such systems are built, and in order to maintain their overall trustworthiness they should be monitored during(More)
In the embedded systems industry, function-centered engineering is commonly applied to address the increasing number and complexity of system functions. During function-centered engineering, the functional design that is created based on the defined requirements for the system is the main artifact that serves as a basis for subsequent development(More)
