If you are looking for ideas on what the best model for structuring a technology department looks like, the chart below offers a suggestion on how you might organize the general technology roles at your school.
There are two schools of thought surrounding the separation of the academic technology leader role from the operations technology leader role. Some believe that it is important to keep the two roles separate - as in separate people - in order to enable the two to focus on their intended areas of duty. Others believe that having a central role requiring the knowledge and acumen of both academic and operational technologies enables a more macro management structure. It is important to identify which camp your school will align with. The model provided in this post allows for either to exist.
The roles in the chart can be combined into one person or split into many. It will depend on the size of your school, the number of people available, and their skill sets.
