I don't think it's fair (or accurate) to say this signals the end of Design Thinking. It could be the opposite. That is, outfits like Ideo have been evangelizing DT for ages. It's been recognized. It's been adopted. It's been assimilated into numerous companies...to the point that fewer need Ideo's services, they developed their own. Perhaps Ideo's success became its downfall?<p>A (loose) example is snowboarding. In its youth it was a fringe activity. If you wanted to snowboard you had to go to certain stores, buy certain brands, and perhaps even visit certain resorts. Independent snowboard-only stores did well. But slowly snowboarding grew and ski stores and big box stores started selling snowboarding gear. The need for dedicated stores diminished. Some of the indy stores closed. That process hardly signaled the end of snowboarding.<p>Of course there are other examples of early evangelists being hurt by their own success.
