How many more times.

I've given the quotes from the original link and the DWP. It is purely "user research", that they do all the time to try and improve things. It is only certain people from certain areas(mainly the north-west) that can VOLUNTEER. It is NOT about assessing them for eligibility or anything like that. It's about trying to improve how the system works. They seem to use it to test out online forms.
How is a new system, being tried out at the moment, that aims to really speed up claims for the terminally ill, a bad thing?
