Specific IT helpdesk related data that I am looking for includes:

- Average size of IT helpdesk for companies in the Fortune 500 (and
Global 500  or 2000)
- Average annual IT budget for companies in the Fortune 500 (and
Global 500 or 2000)
- Percentage breakdown of the average IT budget for companies in the
Fortune 500 (and Global 500 or 2000)
- Percentage breakdown of Fortune 500 (and Global 500 or 2000)
companies that outsource the IT helpdesk, versus staff it themselves
- Average number of employees in the companies in the Fortune 500 (and
Global 500 or 2000), and what percent of these employees are knowledge
workers
- What is the average ratio of numbers of employees to IT helpdesk
staff size

Would appreciate any rated data that can be used in building a
business case for selling software applications into this market.

Please provide reference source of this data.

Thanks.
Brian

Brian --

I'm pretty familiar with material available on the Help Desk/Call
Center markets, yet despair of getting the specific information that
you seek.  Suggested sources would be Gartner Group; Aberdeen Group;
and IDC -- each of which has done a study of the market in the past 12
months.

Also, for the cost of a $215 membership, there's some data available
from The Help Desk Institute, www.thinkhdi.com
