What is the structure of a typical IT department? [closed]

I know most IT departments vary greatly depending on size and type of company, but I'm just wondering what the typically IT org chart would look like.

In small and medium businesses (SME) IT departments have historically grown organically, and often haphazardly.

In large organizations, they have come to mimic typical organizational structure for a department or division, often if not a core business function (i.e. you don't sell IT services) it is viewed as a non-revenue generating expense (like legal, HR, and too often like facilities management).

You'll see a CIO or VP of (Information) Technology at the top, with managers for each divisions.

Common division titles: Operations, Development, Networking (Infrastructure), Information Management / Data warehousing / Database Group, and Client Services or Help-desk. These divisions are not uniform in naming, but often their basic or core function is identical regardless of the naming (Development is sometimes simply called Software for example).

I think ITIL and PRINCE2 might be two sources that could have more "standard" terms or org charts. I cannot think of any other practices or methodology, but anything that is an "expensive buy in, and main purposes seems to exist solely to be the basis to justify yet another re-organization" would be suitable. While this sounds (and is) cynical, I believe most of it is reasonably accurate to be suitable sources for potential answers.

I started drawing a chart to show our IT department but as there is only one of me it just ended up looking like a circle.
