Three steps of content management – edit, preview, publish
It is good to hide from the visitors of your web site the process of creation and edition of pages. Also it is good to have a place where content managers can see how the web site will look after all changes. In case there is more than one content manager it is very likely to have a person who will be responsible for the content of the whole web site – a web site publisher.
With three steps of content management a content editor can create new pages, edit existing pages and preview them. The web site publisher can block changes while he is previewing the web site, and then to publish some or all of new/changed pages.
