IT staffing levels can vary significantly by the size of the company.
?The typical IT staffing ratio (the number of employees supported by
each IT worker) is 1:27 among all companies included in the survey.
However, companies with 500 or fewer employees typically have an IT
staffing ratio of about 1:18, while companies with 10,000 or more
employees have a ratio of about 1:40.?
A detailed chart showing how IT staff ratios by organization size,
annual dollar volume and by total number of employees is available at
the following link:
From the Information Technology Association of America (ITAA):
?By industry, financial services firms have the least number of
employees supported by each IT professional (ratio of 1:11), while
manufacturing and government/education/nonprofit organizations have
the most employees supported by each IT professional (ratios of 1:36
and 1:33, respectively).?
According to The Yankee Group ?the ratio of IT staff support to
personal computers in small businesses is 1:25, while medium-sized
businesses have a ratio of 1:33. In fact, some small businesses and
29 percent of very small businesses have no full time IT staffs at
For Law Firms:
?Based on a set of 20 standard IT job functions, the survey finds the
average ratio of end-users to IT staff to be 35-to-1. This ratio does
not follow a straight line as firm size increases. Interestingly, we
found that as firm size increases, IT staffing grows at a faster rate
than the growth in the number of end-users would predict.?
The top third of very large firms have ratios of 25-to-1 or less. The
top third of small firms have ratios of 35-to-1 or less.
Eight out of 10 very large firms have ratios lower than 40-to-1.
Eight out of 10 small firms have ratios of 50-to-1 or lower.
