Hi Tim,

thanks for pointoing to the interesting document on conducting an 
accessibility evaluation. Our methodology is probably closer to the 
checklist evaluation than to the user-in-the-loop evaluation (but then, 
the role of user testing has not been clarified yet). If we were to 
follow the emphasis on task scenarios, a page sample based testing 
approach would not fit very well. Having, as suggested in the paper, 
8-10 task scenarios per system under test (SUT) each of which would 
contain multiple pages or page states would quickly crank up the 
page/state count to 50 and more.
Interesting is the prioritisation of tasks which would offer a way to 
differentiate criticality and knock-out success criteria: if an 
important SC is not met on a critical task, conformance cannot be 
claimed. This would point to a matrix ov criticality of failure vs. 
criticality of task (scenario).

Regards,
Detlev
