Re: Too much data

Ryan,

When I was designing such a product for EDS, the assumption was it was  
for "doctors" only but when I did user profiling and further  
questioning, what I learned was that THEIR idea of "doctors" included  
the MAs, PAs, and RNs who have to enter info for them many times (or  
pull from same). May I suggest you really take the time to make sure  
you really know the profile of the majority user AS WELL AS the  
minority of users who may be supporting le doctor.
