The numbers are macro numbers.  (I didn't say that, so you couldn't
know, of course.)  This comes out in the wash when the winners and
losers are aggregated.

It's not ROI, it's IRR.  IRR is a generic formula for evaluating
projects, and may include (as in my case) the social benefits.  ROI is
that part of the benefit captured by the investor, which is quite a
different matter.  (Admittedly, I only can measure benefits that are
included in GDP, but that still leaves substantial room for variance
between ROI and IRR.)

How _dare_ you say that _on FSB_?  How can you run a business without
measuring the value of the product?  What value is there to software
besides productivity?
