Managing changes to the OBS

The Organizational Breakdown Structure (OBS) of a company may change over the life of a program. These changes may include modifications to the functional organization hierarchy, personnel changes, or the addition or elimination of levels in the organization. IPP&E ensures that functional work package estimation and execution are performed and approved by the most current functional organization. It is a best practice to keep the OBS structure released and to create a new revision to make any changes.
