This trend in industry is shown through adoption of new terms such as “realistic simulation” and “virtual testing”. This situation creates new responsibility for the engineer to guarantee the required confidence level.
This new approach requires secured processes for the verification and validation (V&V) of simulations bringing evidence of their predictive capability. In particular, programme managers now require formal evidence on “simulation fit for purpose” on which they can build confidence and take decisions. In addition, the increasing situation for extended enterprise creates new constraints to guarantee safe and robust analysis processes.
At the same time, and due to the economic pressure, V&V activities are frequently seen as an additional cost that can easily be reduced and even fully cut, thus underestimating the induced risks. In addition, V&V is not easy to implement because of the diversity of involved persons: managers, simulation experts, test specialists, software developers and quality controllers, software vendors…
