1. Raw materials may be
removed from the storeroom
upon oral authorization from
one of the production
foremen.
1. Raw materials should be removed from the
storeroom only upon written authorization from an
authorized production foreman. The authorization
forms should be prenumbered and accounted for, list
quantities and job or production number, and be
signed and dated.
2. Ashland’s practice of monthly
physical inventory counts does
not compensate for the lack of
a perpetual inventory system.
Quantities on hand at the end
of one month may not be
sufficient to last until the next
month’s count. If the company
has taken this into account in
establishing reorder levels,
then it is carrying too large an
investment in inventory.
2. A perpetual inventory system should be established
under the control of someone other than the
storekeepers. The system should include quantities
and values for each item of raw material. Total
inventory value per the perpetual records should be
compared with the general ledger at reasonable
intervals. When physical counts are taken, they too
should be compared to the perpetual records. Where
differences occur, they should be investigated, and if
the perpetual records are in error, they should be
adjusted. Also, controls should be established over
obsolescence of stored materials.
3. Raw materials are purchased
at a predetermined reorder
level and in predetermined
quantities. Since production
levels may often vary during
the year, quantities ordered
may be either too small or too
great for the current
production demands.
3. Requests for purchases of raw materials should come
from the production department management and be
based on production schedules and quantities on
hand per the perpetual records.
4. The accounts payable clerk
handles both the purchasing
function and payment of
invoices. This is not a
satisfactory separation of
duties.
4. The purchasing function should be centralized in a
separate department. Prenumbered purchase orders
should originate from and be controlled by this
department. A copy of the purchase order should be
sent to the storeroom clerks. Consideration should
be given as to whether the storeroom clerks’ copy
should show quantities.
5. Raw materials are always
