When a change is being implemented, it directly or indirectly has an impact on other families in GE Digital APM. In MOC, you can associate a Change Project with records from other families in GE Digital APM that are possibly impacted by the change. Such records are called Changed Elements.
For example, when the change involves replacing the existing pressure relief devices that were identified as Independent Protection Layers, with a different manufacturer's device, the LOPA assessment with which the equipment is associated may be impacted. In this case, the affected LOPA record is a changed element and you can associate the LOPA record with the Change Project.
Changed elements help keep track of all affected processes and records in one place, which you can then analyze to assess the advantages and disadvantages of implementing the change. An approver can review the changed elements to understand the impact of the change and make decisions on whether to approve or request rework of the Change Project. Changed elements provide your organization with a means of associating impacted areas as changed elements, thus making MOC a fully auditable tool.
By default, you can associate SIL Analysis, Hazards Analysis, and LOPA records as changed elements to a Change Project. If you want to add records from other families, you must modify the Change Project Has Elements relationship family by adding the families, whose records you want to add as changed element, as Successors to the MI MOC Change Project family.
