Spot (Specific Item) Inventory
A spot inventory is an unscheduled type of physical
inventory that is taken to verify the existence or
nonexistence of a specific stock item. Usually, it is taken
as the result of a total NIS indication in the issue request
when the verified stock record for the requested item
shows an on-hand balance; as the result of a partial NIS
issue transaction when the verified stock record for the
requested item reflects an on-hand balance in excess of
the quantity issued; or when a posted issue document
results in a negative stock record balance. A spot
inventory also is taken to determine the on-hand
quantity of a particular item when and as requested by
the commanding officer, a fleet or type commander, a
cognizant inventory manager, or other competent
authority. For example, your commanding officer may
request the physical inventory of any item that the
commanding officer considers to be highly essential to
prospective operations; a fleet or type commander may
need to have total asset visibility of a particulary critical
item; or an inventory manager may request physical
inventory, disposition, and report of certain items that,
after distribution within the supply system, are found to
be defective.
Velocity Inventory
A velocity inventory is based on the premise that
inaccuracies of stock record balances for any given
items increase proportionately with issue frequency, and
consequently, that most of the physical inventory effort
should be concentrated on frequently demanded items.
A velocity inventory, therefore, requires a periodic
physical count of all stock items that experience
relatively frequent demands (fast movers), and a
physical count of items that experience infrequent or no
demands (slow movers) only when such items are
issued. Periodic inventories of SIM items and postissue
inventories of non-SIM items, as prescribed in the
NAVSUP P-485, are examples of velocity inventories.
Material Not in the Custody of the Supply
Department
When you schedule the various different types of
inventories to do, you must also include all the material
that is being stored in other department heads’ spaces.
When doing this be sure you have set up a specific time
to conduct your inventory.
SCHEDULED INVENTORY
REQUIREMENTS
Although a complete physical inventory of all
stocked repair parts usually is taken during ILOS
periodically scheduled for most ships, there is a
continuing need in every ship (whether or not it
undergoes an ILO) to conduct physical inventories to
make sure effective control of those materials normally
required to perform its mission is maintained. Also,
there may be certain material characteristics that require
special management attention. The scheduled inventory
requirements prescribed in the NAVSUP P-485 are
considered to be minimal for effective inventory control
of stock material. (Inventory requirements and specific
instructions for controlled equipage and presentation
silver are included in the NAVSUP P-485.) Items that
can be included in more than one category should be
inventoried under the criteria of the category that
requires the greater inventory frequenty. For example,
if hazardous items are inventoried annually and SIM
items are inventoried semiannually, then any hazardous
item that is designated as SIM should be inventoried
semiannually. See figure 8-4 for an example of a
physical inventory schedule.
NONSCHEDULED INVENTORIES
Nonscheduled inventories are those that are
unexpectedly required incident to significant stock
record inaccuracies discovered during an issue process,
a random sampling inventory, or an annual supply
inspection. Nonscheduled inventories also include those
that are occasionally required of certain items when and
as requested by an inventory manager, a fleet or type
commander, the commanding officer, or other authority.
Spot inventories are examples of unscheduled
inventories. Bulkhead to bulkhead inventories of
specified storerooms and specific commodity
inventories also are examples of unscheduled
inventories when required as the result of an
unsatisfactory random sampling inventory or a supply
management inspection. Although unscheduled
inventories can neither be planned nor included in fiscal
year inventory schedules, the estimated effort required
for such inventories must be considered in the annual
inventory program and in the assignment of supply
department resources.
PREPARATION FOR INVENTORY
Before any physical inventory, you should collect
all unposted receipt and expenditure documents
