[WG-RIUP] NIST 800-64-4

It's a lot to ask for a review from all. So what I did was to highlight every place that I thought mattered to the RIUP team. Highlighted in orange. Risk impact is a big addition - which I think is good. The focus is to do no harm. What I found to be missing is an affirmative action plan to see whether the introduction helped the disadvantaged improve their access to services. Peace ..tom jones
