FW: reasons not to do usability retrospectively?

I would illustrate this point by handing the client a thin piece of
cardboard and telling them--

"I'm testing this bulletproof shield. Hold this in front of your
chest..."

reasons not to do usability retrospectively?

I have currently been asked to make usability recommendations upon an
application which is late in the development phase and almost ready for
release to the user community. I'm looking for reasons why User
Experience
is not a retrospective activity and should be built into the product
from
the start e.g. Lower cost to make changes etc. What other reasons can
anyone
think of?

Much appreciated

Dan
