In the same level approval from all users required or only one user enough to approve, this means I can send a copy of the document to 5 users, and I need approval from all or I need only one of them to approve.
For important documents that need immediate response it can be configured so that if the user not response in certain time another copy of the document send to another user to take action.
For each user in each level we can configure certain time the user should response, and certain time that the document must be approved, if any document approval delays the system can show the responsible on this delay.

At any time, you can know where the document is right now and who should approve it with graphical colored icons and trees easily show graphically the status of the document.
