I completely agree that clients want dashboards and they want to know 
how they compare with themselves over time. No question.

I think the important issue here, is do they want the features of their 
dashboard set as a standard requirement?  I think that all accessibility 
tool makers provide different features and they use the difference 
between those features to both to distinguish themselves competitively 
and to meet the needs of specific industry sectors.

I think we could do harm to the industry if we started writing 
requirements of what was needed in a dashboard and how to do it.

I think our job is to write the accessibility standards that industry 
needs harmonized around the world, without telling tool makers how to 
build their tools and what features to put in them. I don't think W3C 
belongs in the dashboard business. Deque, Tenon, Site Improve, (to only 
name a few who responded to this thread) are in that business and know 
best what they want to give the customers they serve.  Different 
industries or  sectors want different dashboards.

I would never argue the importance of dashboards and measuring 
performance over time.  I don't think standardization is needed there, 
and could actually stifle innovation.
