Design Thinking vs. Data Thinking

Wave failed utterly and was indeed poorly thought-out on a number of levels.
-----------------
I'm not sure if Google Docs is that much more single purposed than Google Wave - it's just that rich documents are something people already understand.
All that said, I think you have a good point about company culture. It's just that companies do have ability to step out of their culture on occasion.
People use Google Maps to make new apps - ranging from practical [http://www.padmapper.com/] to artistic [http://thewildernessdowntown.com/] - on a daily basis while Gmail and Google Docs remain relatively stagnant.
The problem with too much "design thinking" is that you end up trying to "innovate" without taking user needs into perspective. To a designer aching to flex his design muscles, a clean and usable design probably comes off as "bland."
I'd argue that Google is much more usable than its competitors. They don't overdo their design, and that's a good thing.
Perhaps the best was that if you're trying to grow a market then being like your competitors is probably the wrong was to go about. A common expression of mockery with a group of friends is that a company is "trying to differentiate by embracing the dominant paradigm." These seems related.
What's more to the point, testing is for increasing a specific outcome or make sure it happens. It's not about what Christopher Alexander would call "the quality without a name."
