As system complexity increases, organizations are forced to cope-up with these intricacies by introducing and evolving newer validation methodologies. There are multiple systems and subsystems in a vehicle that interact with each other. For example, today the infotainment system interacts with active safety or ADAS systems which in turn talks to the braking system. All this is controlled by the electronics software. This increases the need for development standards in building safety-critical systems that need to be validated thoroughly in software as well as in control systems. Hence, the V&V process has to evolve to capture these changes.
Newer best practices are being adopted in software development like reducing testing redundancy, bringing more optimized workflows and re-using test vectors or test scenarios that can be done at various stages. These demand a robust V&V process.
In traditional V-cycle model, left side is for development and right side for validation. This is changing. Now V&V is shifting more towards the left side of the V-cycle. This is driven by the philosophy 'Earlier you catch, it's less costly to fix'. Ample efforts are being made to ensure the requirements, models and the artefacts that are used in development, go through the V&V stage. So far, the development tools and validations tools were separate but they are now being brought together.
