From a business perspective . . . Data warehouse, financial and retail web-based "port-of-entry" solutions providors, i.e. NCR, see competitive advantage in adding telephone ports-of-entry into these systems. It might be helpful for our working group to compile a list of business cases, such as "telephone ports-of-entry", for developing accessible web pages. A good business case can motivate businesses to do things far above and beyond those actions motivated by conventional legal, moral and ethical reasoning. I would like to compile a list of business reasons for developing accessible web pages for us by our WAI working group. Can you help? Our bucket is empty. Please send water. Thanks!
