Re: Costs of testing with Silver

Hi all

I’ve followed this discussion with interest, and also some concern, some of which has also been expressed by Charles in his contributions.

I recognise the business logic of attaching costs to any additional activity that Silver might introduce on top of current requirements of WCAG, the tension between guidelines as educational tools and measurement tools, and how this might impact on what Silver looks like. I think it’s an important conversation to continue, but I’m concerned at the risk that this conversation might lead to the perception that certain requirements that would benefit specific disability groups are more likely to be rejected on cost grounds. 

There are valid arguments for providing levels of conformance, but I think the arguments are weakened when there’s a clear imbalance between conformance levels and user groups covered at each level. 

The concept of Hierarchy of Disability (or Impairments) has been used to describe and explain the relative historic dominance of certain disability groups over others in terms or receiving attention and support. Past work has shown where WCAG (and wider accessibility discourse) has been uneven in coverage of the needs of different disability groups, and efforts like the COGA Task Force are examples of attempts to redress the balance. 

Any perception that Silver might be the product of a more aggressive cost/benefit analysis before defining requirements might be damaging, especially by members of disability groups who argue that Silver should better represent their needs than WCAG does currently. I hope the conversation can continue in a way that recognises and addresses this risk.
