What I meant was that companies tend to overestimate how much they can get 
done.  While the modified code _does_ tend to perform more poorly, the 
biggest problem is that companies think that they can adjust to the CASE 
paradigm in a short period of time with little training for technical 
personnel.

Why does the new code perform more poorly?  Staff inexperience with SQL 
programming and tuning it for performance is one reason.  SSA's insistence in 
providing AS/Set training that bears no resemblance to how AS/Set is used 
with BPCS is another.  Using SQL when its use is unnecessary is an easy trap 
to fall into -- especially with the sometimes disjointed BPCS file structure.

Primarily, I meant that the more code you modify, the further you're going to 
fall behind.  The project estimation techniques that you've used for years 
are invalid until your technical staff has had at least a year with AS/Set 
and the "new" BPCS...
