I know of a number of careful studies that have examined the claimed
benefits of office automation.  The conclusions are that (1) the
gains are small, (2) productivity is often lower rather than higher,
and (3) very careful examination of actual office processes is
required to obtain any measurable gains at all.

I would welcome references to careful -- not anecdotal or
"perceptional" -- studies that support the opposite claim.

Remember that the PC equipment is far more expensive, requires far
more highly trained people to maintain (as well as totally new
support people like system administrators), requires more training to
use, introduces new bottlenecks (waiting for the printer), has much
worse failure modes (e.g., a server goes down), and has higher
per-page printing costs.  That's why you have to study real
situations very carefully to come up with real numbers.

I'd expect this to be an area where there have, indeed, been major
productivity increases.

Packaged software also forces you to adapt your procedures to its way
of doing things.  I've seen this with every package I've bought as an
end-user.  I don't know how to measure this cost, and I'm sure it
usually doesn't exceed the benefits, but I don't think it's
negligible either.
