More like I was trying to keep my response short ;-).  I think we're all in agreement on pretty much everything:

  1. Understand your problem
  2. Find potential solutions
  3. Find the technical, economic AND situational tradeoffs
  4. Choose the best course of action

My original comment was directed at item #3.  I was trying to remind everyone that a simple cost analysis may point to solutions that simply aren't possible, given business constraints.

I know we also agree that we should constantly fight corporate stupidity and short-sighted budgetary oversight.  But that's a second battle, one that goes on forever.  Sometimes you just have to get the job done within the current constraints.

'Nuff said.

Craig
