Several years ago, I created a spread sheet that used weights assigned to
factors like those above to calculate staff-days ("man-days" before we got
so concerned about gender). This satisfied management's desire for a
"scientific" method while allowing me to apply my years of experience to do
"seat of the pants" estimates. Consciously or unconsciously, I applied
weights that made the spread sheet value equal my "seat of the pants"
You imply that there is somehow something wrong with this. That's what
project metrics (particularly for purposes such as setting staffing levels)
are all about. It's nothing more than a structured, best-guess estimate
of the level of effort required to produce a given product. Only a fool
would try to adhere to some sort of arbitrary benchmark without regard to
factors such as staff experience, project complexity, etc. Inability to
allow for those factors is a weakness in your methodology or toolset, not
a problem with your project management skills.

But, if you *don't* have the years of experience with the type of projects
you're required to estimate, you have to start *somewhere*. I gather this is
the original requestor's problem, and this is a reasonable reason to seek
an "industry standard" or "industry average."
