ZMDM supports comprehensive product information lifecycle management through the use of versions, revisions and a release process. Since ZMDM is multi-user system it minimizes conflicts (and overwriting changes) through the use of Check-in and Check-out process. The following picture shows the lifecycle management concepts used for parts, files and forms in ZMDM.



The picture below shows the lifecycle information of a part.


Check-in & Check-out

Since ZMDM is a multi-user system and supports lifecycle management of master data, it avoids update conflicts (multiple people working on the same data item) using check-in and check-out process. A new version of the data item (file, form or part) is created when a user checks out a data item. Other users cannot edit the data item when it is checked out by another user.
