I think it is important for the committee to understand that we did both internal and external testing. We actually thought you'd take more comfort in external, which was done with stakeholders freely able to choose their test cases. You want to drive to internal testing, so I'll talk about internal, but I'm happy to come back to external.
We did both system integration testing and user acceptance testing. We have full documentation around the number of tickets raised from those processes and what the dispositions are. We've been testing this for close to two years now.
