Workflow allows you to manage the process of content creation and modifications. Kentico CMS enables web masters to prepare customizable workflow or approval processes for different document types and site sections.
You can for example set up a workflow process requiring that marketing managers approve all news published on the web site.

Workflow notification
Appropriate users are automatically notified by e-mail when a new document is waiting for their approval. The document can be edited, approved or rejected by any user who is authorized for the given workflow step.
Versioning
Kentico CMS optionally stores all previous versions of the document so that the editors can view them and roll back to some previous version.
Content locking
When workflow and versioning is used, you can also turn on content locking. It requires users to check out the document for editing. The checked-out document cannot be edited by other users at the same time which avoids two people working on the same document concurrently. After user finishes the changes, she checks-in the document.
