Updating a WBS and Publishing:
The work break down structure is the task hierarchy of a project. We can add/update/delete tasks in a WBS. There will always be a working version of WBS and multiple published versions of WBS. Working version is the draft version where the changes are being made.Published versions are available to the other users and all other standard programs and even custom programs look for the baselined published version since it is the standard and non-updateable ones.
Most of the organizations set the latest published version as the baselined version.
