Chief Information Officer

The CIO runs the technology the company works on. The CTO runs the technology the company sells. Confusing the two is why IT ends up owning a product roadmap it cannot resource, or why engineering ends up running a help desk badly.

What this department owns

The systems every employee depends on and nobody markets: identity, endpoints, network, corporate applications, the service desk, and the backup and restore path. Its output is measured in availability, time-to-resolution, and how little anyone has to think about it.
