From the couple projects I have insight too, one, I believe IDEO bit off more than they could chew, at the time they were offering turnkey solutions - not anymore.
We’ve all had projects that turned to crap by the time they got to production. Why, is another discussion.
Bashing IDEO isn’t the point. Consultancies rise and fall all the time, just like any business. That any ID consultancy gets on TV is good for us all.
