Drivers at Daisy Brand can load 24 pallets on their trucks in 20 minutes. It used to take them an hour. The reason for the difference? RFID technology.
Daisy Brand's adoption of RFID technology is helping the 75-year-old, privately
held company increase its product throughput and expand its customer base. The
technology increases inventory visibility and it enables its drivers to manage
their own workloads.
Daisy Brand (www.daisybrand.com)
produces sour cream at its 50,000 sq.-ft.
manufacturing and warehouse facility
in Dallas. It makes four different formulas that are packaged for retail or
food service. Packaging sizes range
from single once servings, 8- or 16ounce containers for grocery stores, to
10 lb. buckets and pouches. Finished
goods SKUs number 30 to 40. Its sour
cream products are distributed nationally with assistance from third-party inventory locations across the country to
customers like Wal-Mart, Albertsons,
Safeway, Kroger's, Target, and the U.S.
Department of Defense.
The Wal-Mart Effect

that
volunteered to participate in Wal-Mart's RFID-compliance initiative in 2005.
"We were one of the early adopters in the perishable space," says Kevin Brown,
director of information technology. We saw it as an opportunity to take a leadership
role in the application of the technology."
The company succeeded in meeting Wal-Mart's go-live date. Today,
uniquely assigned RFID-tags are applied to cases for Wal-Mart, and all of
the finished goods pallets that come
from its manufacturing plant. The
cooler temperatures in Daisy's refrigerated warehouse do not affect the
read performance of the RFID tags.
However, in colder environments,
such as frozen foods, RFID tags need
to have a stronger adhesive so they
stay attached to cases and pallets.
Every time a tagged pallet is touched, an inventory transaction is automatically
recorded in the company's Protean ERP software from Infor (Alpharetta, Ga.,
www.infor.com). The system is driven
by the pallet's location at a particular time and by what the lift truck driver
tells his onboard computer about what he is doing with the pallet. The system
then generates the appropriate inventory transaction.
Daisy shares information with WalMart through advanced shipping notifications transmitted through EDI.
Wal-Mart either lets a Daisy manager
access to its retail inventory management system, or go into its decision
support system and query information on Daisy's RFID tags. Brown says
he can see information about Daisy
Brand's products in Wal-Mart warehouses and stores at a defined time
for a particular SKU. Wal-Mart also
sends him the information in an Excel file on a periodic basis transmitted
through email or EDI.
Drivers on board
In late 2005, the company's management team decided
to leverage its RFID investment and move from a manual to an electronic, real-time
inventory tracking system. Initially, Daisy's drivers were concerned that jobs
were being automated, but managers were successful in getting its drivers to
accept the new system because it brought them into the implementation process
from the beginning.
Drivers participated in designing the
data entry screens, determining the
best ways to load trucks, how to deal
with exceptions, and what to do if a
truck arrived late and how that would
affect the workflow. The new system automates the drivers' data entry duties
and lets them concentrate on managing their workloads based on the number of orders and shipments that need
to go out the next day.
"They are the ones in control of that.
We tell them the scope of the work; they
are responsible for executing it," says
Brown. "The great part about this is as
soon as they get their work done, their
work is done. If they get done early,
they go home early. If they get done
late, they go home late. It is a win-win
situation. We still give them the power
to control their own destiny as to how
the work will be completed, but we have
given them a technology that is smart
enough to help them collect all of the
data we need to run the business."
It takes two weeks to train new
drivers on the system. Daisy Brand
has even developed some online
training modules for drivers that include simulations.
Data Collection
The RFID labels that Daisy Brand workers attach to the pallets contain information
about the product including the date and expiration codes and pallet IDs, plus
a bar code and shipping information. In effect, the RFID tag is the license
plate for the pallet that all customers can use.
The company's fleet of Crown (New Bremen, Ohio, www.crown.com)
lift trucks carries Windows XP rugged tablet computers that are integrated with
an RFID reader and antenna. Since RFID technology is rapidly advancing, Brown
made the decision to load the tablet computers with iMotion software from GlobeRanger
Corp. (Richardson, Texas, www.globeranger.com).
The software transfers the scanned tag data to Daisy's proprietary software,
which sends the driver information about where to put the load. The system records
the transaction, the lot, the expiration date, and the move from finished goods
to shipping. Because Daisy Brand's products are perishable, tracking expiration
dates and rotating product to keep it fresh in the supply chain is critical.
"Our traceability is very high from
raw materials to where finished goods
are shipped," Brown says. "I can run
queries against pallets and tell you
everywhere that pallet has been and
what lot it came out of during the company's production cycle and, hopefully, back that up into what raw materials were consumed. Traceability for
food safety gets enhanced greatly."
To track what the company needs to
track, programmers set up the inventory management system to include
the appropriate business rules that tie
into required customer service levels.
All that lift-truck drivers have to do is
follow the prompts.
"This is more information for a lifttruck driver to remember. He has too
many other things to worry about. You
want him paying attention to where he
is driving not doing a lot of data entry
and recording things. We want them
worried about getting the truck loaded
right," says Brown.
When drivers pick up a pallet, they tell the system what they are doing with
it; the system does not tell them what to do with the pallet. "The drivers know
how to rotate the product better than we do. So the system does not have a directed
putaway. But it can and does suggested gets. It a driver needs a particular
product; the system will tell the driver where the product is in the rack and
what the freshest code date is," he adds.
As soon as the driver picks up a pallet, he knows whether or not he has the
right one. The system will tell him if he
picked the wrong pallet or is trying to
drop the right pallet on the wrong
truck. It won't allow the transaction to
be recorded if a driver tries to load the
wrong pallet on a truck, or the right
pallet on the wrong truck.
As soon as a truck is loaded, the system validates the contents of the
truck against the order in the company's ERP system and if it is still in
sync, the driver records the trailer
temperature and cleanliness. Once
he indicates "truck done," and pushes
a button on the tablet PC, all of the
bill of lading materials printout at the
dock and the truck driver is on his
way. At this time an advanced shipment notification is sent to the customer. The shipping memo is also recorded in the company's ERP system,
triggering an invoice.
Future Direction
Daisy Brand is in the process of breaking ground on
a new plant in Casa Grande, Ariz., that is expected to be completed in 12 to
18 months. The same RFID system will be implemented at the new facility. Data
from the system will be sent to the main office in Dallas, where the inventory
will be managed.
When the new facility comes online, Daisy's order management team will be able
to see where it has inventory in all of its warehouses. They will be able to
determine the most efficient distribution of product based on inventory availability
at each plant. Brown says, "This gives us a lot of flexibility in the future
about how we manage our supply chain and what products are moving where."
