Usually, with a CMS, there come some predefined user groups and workflows.
You have different edit pages, and not everybody is allowed to edit all kinds of items. This usually means permission groups on the actions and items.
Usually, you have rules for publication approval of items, and maybe you can't publish your own items but have to have somebody else from a similar group approve that item.
Also, asset management like pictures of people, and a structure that keeps things that are used together available together, like a slideshow that accompanies are something I'd expect to find in a CMS.
