Drupal has a lot of power under its hood, which makes developers and site admin very happy

Workbench is a big step towards solving that problem. It's a very simple interface that lets users add, delete and edit content easily (based on business and organization roles, not just Drupal's user roles). Once installed and enabled, it sets up a nice little My Workbench page to manage content.

It gives us three important solutions:

• A unified and simplified user interface for users who ONLY have to work with content. This decreases training and support time.
• The ability to control who has access to edit any content based on an organization's structure not the web site structure
• A customizable editorial workflow that integrates with the access control feature described above or works independently on its own
