Project processing (revision procedures) can be divided into a fixed sequence in DocWorkState, such as basic engineering, detail engineering, etc. Subordinate document purposes, such as "for review", "for approval" or "for attestation", etc., describe what is to happen to the document, also in a fixed order.

Within the framework of DC Phase Controlling, the DocWorkState now becomes the "DC Phase" and the document purpose becomes the "Action" package. For each "Action" package there is a ToDo template that controls the revision process. This is assigned to the action package.

The combination of a DC phase with the different "action" packages results in a DC structure tree.
The DC phases link the individual steps in the project flow with the PLM project management and ensure that the stored documentation has passed through the individual processing steps of the revision procedure in a controlled manner during the project flow.
