A good secretary is like an NCO in the army of your choice (was: Re: It can become cost prohibitive)
They run the place.
Free hint to all consultants: ALWAYS ask the secretary about the Boss's computer knowledge. You can save a lot of time and trouble for a lot of people over the long haul.
I know of several CEO-types of Fortune-500s who make a big show of "checking the computer", even though their network cable was "accidentally" never installed.
I can't count the number of times I've swapped the Boss's top of the line CPU, gathering dust and spiderwebs under his credenza/return, artfully changing screensavers every couple minutes, for his secretary's underpowered kit ... without the Boss noticing.
