Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

IT Operations Manager

Directing IT and telecommunications network installation and operations, advising commanders, and coordinating across headquarters transfer directly to IT operations oversight.

What the civilian work involves
  • Direct daily operations of department, analyzing workflow, establishing priorities, developing standards and setting deadlines.
  • Meet with department heads, managers, supervisors, vendors, and others, to solicit cooperation and resolve problems.
  • Review project plans to plan and coordinate project activity.
