Peter, my intuition says you're on to something here.

I was reading the development diary of the Android game "Replica 
Island". The game was reporting usage statistics back to the server, so 
he could see which levels were inherently harder, where people were 
having troubles, and therefore which bits of the game were demanding 
redesign.  (I don't know if he did redesign anything in the end, but the 
data was there to see).

In the app I just released, I learned very valuable things watching 
people try to play with it without training of any kind.  I watched them 
make "mistakes" and fail to use the program in various ways.

The places where they failed to accomplish what they wanted were areas 
that needed to be improved..."bugs", if you will.

Oh, the program demonstrably functioned, but if it did not meet with 
user expectations and make them more productive, then it's not meeting 
the design goals.

So it would seem that the initial design,coding and delivery is no more 
than half the ideal process.  There needs to be a feedback loop where 
the user interaction is observed, quantified, and learned from to 
improve the app.
