It lets you test out the intended program features and solidify the
specification.  In fact you often don't start with much of a
specification at all, but rather just a general idea of what you're
trying to do.  Then you try things out, squeeze things in, get feedback
from users and iterate the design, etc.  At the end you've got something
you can use as a reference when figuring out what a more permanent
version should do.  It's like making a pencil sketch before starting an
oil painting.
