IT departments have never done a very good job of using titles that actually relate to what a person does, and they certainly haven’t kept up with all the changes in technology. I frequently see IT professionals trying to “live” with the title they were given, despite the fact that it is a complete mismatch for their actual responsibilities.
For example, the title of IT director can cover a wide range of responsibilities depending on the size of the organization and their technical initiatives. One IT director might have a small 2-person shop and perform the role of a Systems Administrator and IT Project Manager, while the other person might manage 30+ staff members and work at the CIO level. This conflict needs to be resolved in the resume, without misrepresenting the facts.
