OPMprocess

basic information for OPM activities

Operational data

Maintenance concept

Documentation of original results of SMA

as LSA tasks with interval, MTA und

packaging of the tasks

Adjustment of Scheduled Maintenance because of OPM results

! IMPORTANT !

In the LSA database, the complete viewcomplete view on scheduled maintenance is documented:

Single tasks with original interval / packaging / OPM adjustmentSingle tasks with original interval / packaging / OPM adjustment (traceability to original task is guaranteed by complete documentation within LSA database)

OPM process will be integrated into S4000M as an own chapter (in the next issue).
