We are very similar
We also have 5 people.. It manager, ERP/BI specialist, 2 sysadmins, helpdesk.
We run about 150 laptops worksations in 6 locations, an AS400 and 20 servers.
I feel we have a good size staff. We are always busy, but never too busy to repond to problems or investigate new projects.
We try do everything in-house and outsource very little.
We have a team that works well toether and we all multiskill to help each other out as far as we can. Management have high expectations of IT and we manage to meet those expectations almost always.
If you are prepared to outsource more, you can get away with fewer full time staff. If you employ very junior people, you will need more. You have to get the balance right.
