Re: Re[2]: acceptance criteria for new success criteria

David: I think the concept of high inter reliability of experts is as good as we can get.

AWK: I think that the "General agreement, characterized by the absence of sustained opposition to substantial issues” actually matches the way that the group operated in practice, and continues to do so.  What we are really doing is following the WCAG and W3C process (see http://www.w3.org/WAI/GL/decision-policy), and our goal is unanimity, or an absence of objections.  Whether this means that everyone actively agrees or if most people agree and the rest can live with it doesn’t really matter.

I’m concerned about the “8 of 10” since it starts to feel like voting and that hasn’t been the way that we have operated historically.

I am happy with this standard


"
In practice, the standard was: "participants in the working group, by consensus, are confident that 8 out of 10 informed evaluators would agree in their application of the proposed success criterion" (across a wide range of cases, I assume, though this last point is usually left implicit). "


All the best

In practice, the standard was: "participants in the working group, by consensus, are confident that 8 out of 10 informed evaluators would agree in their application of the proposed success criterion" (across a wide range of cases, I assume, though this last point is usually left implicit).

So far as I am aware, no one has empirically tested the extent to which this standard is met by the success criteria that ultimately comprised WCAG 2.0.
