Changing the approach to how we collaborate doesn't necessarily have to mean changing the science we use to make assessments of these products. For example, when a trusted regulator like the Australian APVMA has completed a full risk assessment on a product, we should be able to reference that, rather than needing to restart the process.
To answer your question, I don't think it necessarily means that we should compromise science, safety or the rigour we have in our processes. It means that we can incorporate some of the learning, science and data from trusted jurisdictions in our decision-making process to help speed up timelines.
