all the PM tasks that must be done during the coming month. An advance
schedule of downtime tasks, covering the next three months, is also in-
cluded. This advance notice assists the plant manager in planning down-
time task performance in case an emergency shutdown occurs. The com-
puter schedules are accurate because maintenance task timing is based on
the date they were last performed and the frequency assigned. A typical
page from a preventive maintenance schedule is shown in Figure 2-2. A
typical page from a projected downtime maintenance schedule for the
coming three month period is shown in Figure 2-3.
Along with the schedules, the data processing equipment prints out a
deck of cards to feed back completion or rescheduling information.
These cards are used by plant maintenance personnel to record actions
taken, time expended, date completed, and any pertinent remarks con-
cerning findings when the task was done. The cards issued to the plants at
the beginning of the month must be returned to the operations home of-
fice for computer processing on the last day of the month. Figure 2-4
shows a representative feedback card.

Performance Reports

The preventive maintenance performance report shows the tasks which
are performed on time, performed late, are rescheduled, or remain in a
