Vendor-Managed Inventory
Delivered to the 20th International Distribution and Supply Chain Specialists' Meeting at the Frankfurt Book Fair, October 6, 1998
by Mike Shatzkin
I
have spoken at several of Vista's London and New York Conferences and
written in a number of places before about the concept of Vendor-Managed
Inventory applied to the book business. This is the first time I have
done it for a truly international audience. I want to apologize in advance
for presenting these ideas almost entirely within an Anglo-American,
with an emphasis on the American, context. In
the British and American markets, it is clear to us that our supply
chain is not nearly as effective as we would like. Returns are high,
possibly as high as fifty percent of the copies of new titles shipped
for many consumer segments in the US. Returns are not as dramatic, but
they are climbing, in Britain. So
what we are doing isn't working. Vendor-Managed
Inventory, by which the responsibility for choosing the content and
timing of shipments to each location moves from the buyer to the seller,
is the best hope to improve that performance to the benefit of the entire
supply chain. VMI would be helpful whether it were offered by a wholesaler
across the range of possible titles or by individual publishers for
their titles alone. VMI would improve a store's performance, and sharply
reduce their operating costs, whether some or all of their books were
supplied this way. Here's
how VMI works. The supplier -- the publisher or wholesaler -- agrees
on inventory limits with the store. Those limits can be across-the-board,
or can be assigned by subject section. Of course, the limits would change
with the calendar, just as a store's sales do, and just as a store tries
to make its inventory do to be in step with its sales. Granularity to
the level of store sections is optional, but it is a requirement that
inventory limits be set for each individual retail location in any circumstance
where an agreement is being made centrally for a group of stores. Then,
somehow, the publisher or wholesaler must know what actual sales are
in each of the locations being controlled. In the past, like when my
father first installed VMI at Doubleday in 1957 or even when we did
it at Two Continents in the 1970s, the only way to do that was to send
in a sales rep to take a physical count of books on hand. Today, that
data is retrieved effortlessly by EPOS systems, making it efficient
for an offsite supplier to get up-to-date sales information as often
as desirable, even daily. Based
on the sales and inventory reporting, the supplier then calculates the
next shipment and makes it. On a periodic basis, a scorecard of the
actual results will demonstrate whether the supplier's control is sufficiently
profitable. A store using this system with many publishers would, of
course, regularly adjust the inventory limits to give more profitable
publishers a larger inventory allowance, taking shelf space away from
less profitable ones. The
suppliers would achieve better results to the extent that they used
sound statistical prediction methods to calculate future stock needs
from sales data. You need a good buying system to maximize the opportunity.
They would also achieve better results if they ship more frequently,
which will permit them to address out-of-stock situations faster and
to avoid shipping big quantities in anticipation of future sales. It
is precisely those shipments which result in a disproportionate share
of the books returned. Shipping more frequently is the most obvious
leverage provided by VMI, which eliminates the need to put a selling
bureaucracy in touch with a buying bureaucracy to trigger a purchase
ordering mechanism. That clears the most significant barrier to frequent
shipment. Obviously,
VMI cannot work without controls. If the store sets no inventory limits
or there is not some other control like a consignment payment arrangement,
there will be no discipline to force publishers or wholesalers to pick
the right books, or to avoid "loading" the store. And if there is no
benchmarking of what the performance was when the store did the buying,
and no scorecard of the supplier's performance, there will be no reliable
way to confirm that the situation has actually been improved. Time
does note permit elaboration today on the many ways VMI actually works
to increase sales and reduce returns. I would refer those of you who
want more detail on that point to some of my prior speeches, which are
on both Vista's and Idea Logical's Web sites. But, frankly, any technique
that increases the frequency of inventory replenishment will increase
sales and reduce returns. VMI offers enormous efficiencies in addition.
It cuts the need for selling staff and buying staff. It eliminates the
need for the elaborate marketing preparations that are now required
for publishers to sell the books into the stores before publication.
It enables instant publishing and distribution in ways that cannot be
conceived in today's marketplace. Our
company is now deeply involved in one VMI development and on the cusp
of another. Our client, The Butterick Company, is a creator of patterns
for sewing garments. They have almost universal distribution into the
stores that sell fabric. Starting in early 1999, the newly formed Butterick
Book Distribution Company will place the books of all publishers into
that marketplace in the US. The initial customer, JoAnn's Fabrics of
Hudson, Ohio, has 1200 stores for which Butterick will become the exclusive
books supplier. All shipments, and there will be a shipment each week
to each store, will be via VMI. Butterick
could not have made this deal with JoAnn's if they had not offered VMI.
The ceding of control is not a barrier with the account; it is seen
as a great advantage by the account. We
have also been asked for help by the Canadian arm of a global book publishing
company that wants to begin offering VMI to its domestic bookstore network
in 1999. In
addition, VMI is being tentatively introduced at the margins of the
US book trade by publishers at the edges of true trade publishing, specifically
publishers of calendars, computer books, and mass-market juveniles.
And it is tending to be introduced in non-book outlets, which would
otherwise require a big investment in the personnel and systems necessary
to manage book inventories, and which show little inclination to accept
such substantial costs. One wholesaler, Advanced Marketing of San Diego,
which is a supplier primarily to mass marketers, has begun to stock
books for their customers using VMI and is claiming great success. But
while take-up of the concept seems to be increasing, it is certainly
not pronounced enough to be labelled a trend. Despite widespread recognition
of the ills in the supply chain, there is real built-in resistance to
the concept. Chain stores and multiples have invested heavily in buying
staffs, buying systems, and an infrastructure, often including warehouse
and shipping capabilities, to service the status quo. That represents
a core constituency in their organizations to maintain it. And
the changes that would be wrought by VMI threaten many in the publishing
companies too. The whole catalog-and-sales conference, seasonal selling
cycle would be changed. So would the placement of large speculative
quantities of books in advance of publication, preceding any true consumer
reaction. The compensations for these changes: faster and more direct
access to the consumer, the ability to keep books alive easily even
at low sales levels if bookstore customers are indeed buying them, will
take awhile to prove out and provide relief from the discomfort of losing
established professional rhythms and expectations. VMI
is a sensible idea for a supply chain that is desperately looking for
one. It gets easier every day as EPOS technology spreads to universality.
VMI has become is a concept that no publisher concerned about the level
of its sales, the level of its returns, or its costs of doing business,
can afford to ignore.
