The
situation:
TTI, Inc. distributes passive electronics products,
which are the lowest unit-priced components in the electronics arena.
The company has been successful in executing its specialization while
the industry as a whole has pursued more glamorous, more costly products
such as semiconductors and computer-related products. TTI's business
model is designed to simplify the purchase of passives, which allows
buyers to concentrate their efforts on the larger dollar expenditures
where greater cost
savings can be achieved for the time spent. From the beginning, TTI's
mission was to offer extensive inventories, exceptional product
knowledge, and superior customer service. The company has seen its size
double in the past twelve months, and has seen a fivefold increase since
1995.
"We're in a business that experts say we can't make a
business out of," said TTI Senior Vice President of Corporate
Operations, J.D. Beasley. "It's the 'low end' of the electronics
business. Our average selling price is very low. We have to be expert in
getting products in and out. You can't touch the items three or four
times, or your profit is gone. There are products we sell by the
truckload every day that sell for less than a penny."
When
a company has the kind of product storage and flow considerations TTI
does, the way it stores and handles materials is crucial. TTI maintains
181,000 SKU's in the building, and routinely adds 1,000 brand-new part
numbers a week to the inventory. "We've been doing that steadily," said
Ty Golden, TTI's Manager of Warehouse Operations.
"We did a detailed study; we hired consultants; I laid
out for them what I wanted. First and foremost, I wanted to get rid of
our totes," said Beasley. Totes were integral to TTI's operations, but
the company realized that it needed to rid itself of totes in its
distribution operations to reach its goals for efficiency and customer
service.
Said Beasley, "I wanted to pick in real time,
eliminating the need for totes. I wanted to move our products from one
end of the plant to the other without a roller conveyor.
After a long and expensive process, the consultants
said it couldn't be done. TTI decided to do it themselves. Then Beasley
and the TTI staff went to work.
The Impact
In TTI's previous system, each operator was assigned
two carousels, which was considered a pod. Ladders were used to reach
the various bins on the carousel. TTI's automated system would assign a
tote to each order. At any point in time, TTI had over 4,000 totes in
operation. TTI found that managing the totes was becoming a bigger issue
than managing the product itself.
Beasley
smiled and commented, "I found myself having nightmares about our sea of
totes!"
Once an item was picked it sat in the tote until other
items were complete. This occupied valuable space and slowed the overall
process. Upon completion of their picks, the operator would set the tote
in front of their workstation awaiting a dedicated delivery person to
move it to its next station. This was slow and left the door open for
quality issues.
"Anytime a picker has to leave her workstation in the
course of a day," commented Golden, "it opens up the potential to lose
focus, and increases the possibility of someone making a mistake."
TTI realized it was not in the business of managing
totes, but in the business of efficiently fulfilling customer orders.
Operators would often run out of totes since they had to be hand-carried
between picking stations and consolidation.
Gene Pfretzschner, Director of Logistics,
commented, "During this time, TTI was experiencing rapid growth and
space was at a premium. As I reviewed our warehouse flow, I found not
only the management of totes to be slow and complicated, they were
occupying valuable warehouse space."
"It's hard for 4,000 totes to look neat," said
Beasley. (Continued)
