The hard part in determining any ROI is that there are many overlapping
contributors: marketing, system development, training, finance, etc. UCD/UED
is just one and it's difficult to extract the benefit it provides from the
mix. There is a plurality of stakeholders and each is able to report the
benefit by casually excluding the others.

Just look at the other thread: "Has anyone succeeded in getting a
usability-only release?" By the responses, it would appear that pure play
usability is uncommon. So in the majority of cases, the ROI / benefit
correlation is going to be tainted if you try to match benefits to
contributors.

Everyone has a hand are in the pot...which isn't a bad thing. Maybe it just
indicates that accepted ROI analysis (NPV in particular) is too singular and
do not account for the orchestration between many players.

[also, my apologies if anyone received this twice. I think I bounced this
post earlier.]

I can vouch for this.

Processes don't make better apps, designers do.
