Publication Workflows

Hi,

Just wanting to understand a bit more about the capabilities of WordPress.

We have a current CMS and one of it's strengths is publication workflows. That is we can define groups, make staff members of any number of those groups, and then create publication workflows.

Basically when a page is published, if a publication workflow is applied to the category it is posted in, any members added to the workflow get notified that a page is awaiting their approval prior to going live.

Does WordPress have this functionality, and if so could somebody be kind enough to direct me to the relevant technical info?
