Re: Scoring and Dashboards

Hi Rachael,

> If we dictate vs acknowledge depreciation, how do you propose we address
organization’s’ differences in development and deployment  environments and
cycles?

We don't. We simply state that in the W3C's WCAG 3.0 conformance model,
those higher-order 'user-tests' will need to be re-run after "X" period of
time *if you want to report using the W3C model. *

I acknowledge that it will likely be an arbitrary decision in some ways,
but I think that collectively we can arrive at a consensus period of time
(I'll suggest 2 years, based in large part on the fact that our WG has
previously agreed to publish updates every 2 years, but that is just a
suggestion).

Presuming that legislators take-up our new specification (which is STILL
not a given), organizations will adapt to the new reality as part of their
legal obligations. They can manage that as they see fit, based on their
ecosystem.
