I am doing some research RIA applications and one of the aspects that are
often mentioned is the ROI aspect. Macromedia and other pro-RIA 'activists'
claim that when you do RIA instead of HTML sites, the ROI will be higher.
However, I cannot find ANY scientific evidence that supports this
assertion!!!! All documents that I can find make suggestive conclusions in
favour of RIA's and even without comparing the RIA to an alternative.
For example, it is said that when Mini launched their RIA Car Configurator
it boosted their sales so much that their sales targets were exceeded by
25%. That is very suggestive reasoning to me. Where is the evidence? Did
they have a car configurator before? Did they launch a marketing campaign at
the same time?
If RIAs are better than HTML I'd expect stories where an HTML application
was redesigned while keeping the same functionality and the ROI was actually
higher. And of course all other variables kept constant.
Another angle is that I wonder how the ROI is actually improved most. Is it
because of higher revenues or lower costs?
Does anybody know of solid info on ROI stuff and RIAs?
