A client sent me on a ‘dig-around-the-Internet’ exercise to help him get a broader understanding of who defines the ‘s’ and ‘m’ as what when it comes to SME in the UK IT industry.
Here’s what I found:
FSB, Microsoft, Symantec, Citrix, Wikipedia, UK Government, & the EU European Commission: up to 250 employees for medium and up to 50 for small
Gartner: up to 999 for medium and up to 100 for small
CompTIA: up to 500 for medium and small (IT Industry Outlook 2013: Section 1)
IBM & VMware: up to 1,000 employees for medium
It looks like if you’re going to set a definition based on headcount alone go with <50 employees for small and <250 for medium. I’d suggest taking everyone else’s definition with a pinch of salt, particularly if they push a particular product your way that doesn’t fit… they’ll soon come around ;)
For anyone looking at turnover consider ~<£40m for medium and ~<£8m for small.
