- Verification and Validation (V&V) of automated systems is becoming more costly and time-consuming because of the increasing size and complexity of these systems. Moreover, V&V of these systems can be hindered if the methods and processes are not properly described, analysed, and selected. It is essential that practitioners use suitable V&V methods and enact adequate V&V processes to confirm that these systems work as intended and in a cost-effective manner. Previous works have created different taxonomies and models considering different aspects of V&V that can be used to classify V&V methods and tools. The aim of this work is to provide a broad, comprehensive and a easy to use framework that addresses characterisation needs, rather than focusing on individual aspects of V&V methods and processes.To this end, in this paper, we present a multi-domain and multi-dimensional framework to characterize and classify V&V methods and tools in a structured way. The framework considers a comprehensive characterization of different relevant aspects of V&V. A web-based repository has been implemented on the basis of the framework, as an example of use, in order to collect information about the application of V&V methods and tools. This way, practitioners and researchers can easily learn about and identify suitable V&V processes.

Conference paper (peer-reviewed)abstract
- The complexity of systems continues to increase rapidly, especially due to the multi-level integration of subsystems from different domains into cyber-physical systems. This results in special challenges for the efficient verification and validation (V&V) of these systems with regard to their requirements and properties. In order to tackle the new challenges and improve the quality assurance processes, the V&V workflows have to be documented and analyzed. In this paper, a novel approach for the workflow modelling of V&V activities is presented. The generic approach is tailorable to different industrial domains and their specific constraints, V&V methods, and toolchains. The outcomes comprise a dedicated modelling notation (VVML) and tool-support using the modelling framework Enterprise Architect for the efficient documentation and implementation of workflows in the use cases. The solution enables the design of re-usable workflow assets such as V&V activities and artifacts that are exchanged between workflows. This work is part of the large scale European research project VALU3S that deals with the improvement and evaluation of V&V processes in different technical domains, focusing on safety, cybersecurity, and privacy properties.
