OPTION 1
This option is the most common; you designate the most technically-savvy person on staff to be your make-shift IT manager and only bring in outside help when your “internal guru” runs into a network crisis they can’t solve.
Problem is, you are pulling this person away from the real job you hired them to do AND unless they have the time to stay up-to-date on the latest developments in IT support and management, they don’t have the skills or knowledge required to properly support and secure your network.
This inevitably results in a network that is ill-maintained and unstable, which then results in excessive downtime, overspending on IT support, and expensive recovery costs.
