[IxDA Discuss] Rationale for *not* using UCD

[Phillip Hunter]

Is it not a little more accurate to say that quantifying the correlation is
difficult?  Certainly there is correlation.  

Also, I suspect, as with most human effort, that a straight and universal
time-to-benefit measure will never be seen.  Which also leads me to suspect
that perhaps one day we will be able to know and evaluate all the factors
that should be examined and evaluated to produce estimates of benefit.

Of course, everyone is *not* in agreement with this statement.

However, everyone I've encountered who has actually tried to collect  
data and measure the results is in agreement with it.
