Hi Shawn

I'm kinda liking aspects of this approach (ACT Rules format for testing
flows), but (of course) I have a critical question: *how do we score
something like this*?

Each site(1) is going to have "critical paths" but few sites will be
sharing the same critical paths. Additionally, some paths or tasks (find
hours of operation) are significantly easier to do then others (update my
emergency contact information on my companies HR intranet), especially if
it pre-supposes that *all* paths start at a site's "homepage" (and/or the
outcome or solution to Success Criterion 2.4.5 Multiple Ways - i.e. a
sitemap page or search results page).

No matter which, it seems to me that testing a critical path needs to start
*somewhere*, and for a scalable and repeatable testing regime, about the
only thing all sites have in common is a 'homepage', which is something
your example already suggests:

   1. Load the pizza restaurant's site
      1. Possible inputs: found via search engine, hit a bookmark link,
      selected from browser's history, etc.
      2. *Main page loads* with focus at the top of the screen

Open question: is this a correct interpretation? Does all critical path
testing need to start from a common starting point?

Additionally, how do we ensure that *all *critical path testing is scoped
by any given site? (the current scoping proposal leaves it to the
site-owner to scope their conformance claims, so leaving out complex or
critical flows that are non-conformant could be easily overcome by simply
leaving those flows out of the testing scope).


(1: site being an euphemism for 'online digital activity or presence' - as
we need to take XR and other emergent tech into account as well)
