 3. MASTER SCHEDULING. Master Scheduling is the orderly establishment of a
time frame for completing each job subject to Master Scheduling, and the
assignment of these jobs on a weekly basis within shop forces capability,
Following are Master Scheduling procedures:
a. Adjustments. Master Scheduling establishes a coordinated plan for
accomplishment of major jobs (Specific Job Orders). It firmly commits Work
Centers to jobs for specific weekly periods. Once the plan has been accepted
and agreed upon, adherence to the schedule should be mandatory to assure that
the work progresses in the most economical manner. The Master Schedule should
not be adjusted to meet minor changing job conditions or actual performance
deviations. The Master Schedule should be modified only when there is a major
change in work scope; when major delays occur as a result of the nondelivery
of material; or when the entire schedule is disrupted by emergency
conditions. The basis for the Master Schedule is the Shopload Plan.
b. Procedures. The Master Scheduler, under the supervision of the
Maintenance Division Director is responsible for the Master Schedule. Under
unusual conditions the Master Scheduler could be located in the Facilities
Management Engineering Division; however, the basic principle is for the FME
Division to be concerned with medium and long range planning and the shops
with work execution. Close coordination is required between the two divisions
to assure that longer range planning and the Master Schedule are compatible.
The Master Scheduler develops the scheduling plan on the Job Schedule, NAVFAC
9-11014/26, (Figure 9-1) then awaits notification of material availability.
Material availability, however, does not mean full receipt of material. For
example, where paint is not needed for building repairs until four weeks after
the job has started, material availability would be realized if delivery of
paint is assured within that four-week period. Once the estimated date of
material availability has been established, the Scheduler completes tentative
job schedules by establishing time periods when Work Centers involved will be
available to accomplish the work in accordance with the tentative job plan.
Prior to the weekly scheduling meeting, each Branch Manager should review the
tentative job schedule to become familiar with the jobs to be considered at
the weekly selecting meeting. No action is taken during this period except
that a Branch Manager may correct or adjust the tentative job schedule. Such
corrections or adjustments are coordinated with the Master Scheduler. All
tentatively scheduled jobs are carefully reviewed at the weekly scheduling
meeting and necessary changes are made so that each job schedule becomes the
most economical plan of action for that job (Figure 9-1). The end result is a
firm schedule for each job which is posted on the Master Schedule Board and
which must be adhered to by all Work Centers. The Master Scheduling process
is shown on Procedure Chart No. 7.
(c) Personnel Availability. In preparing the tentative job schedule for
review at the weekly scheduling meeting, the Master Scheduler must have
information on personnel availability for each Work Center, and know not only
the total hours that can be scheduled for each Work Center, but how many of
these hours have been previously committed.
(1) Work Center Labor Hour Availability Log. Figure

example of a plastic covered work sheet that is commonly used
to determine
personnel availability. It displays for each future week the
total average
hours available for Master Scheduling in each Work Center and
the hours that
