Site Selection – Part 3 – Match Your Network to Your Business Strategy

However, Gillette's theoretical analysis ended up taking a backseat to a practical consideration: The company was locked in to significant lease commitments with its current warehouses, which made it prohibitively expensive to just pack up and leave. So the question became: How can Gillette deliver much better customer service without changing its physical infrastructure?

"The goal was, at a minimum, to have a warehouse on the East Coast that carried all of our products," Knabe says. Ultimately, Gillette ended up keeping both its Massachusetts and Tennessee DCs, but what changed was how they functioned in terms of what products they carried and who they shipped to. Both warehouses now stock all Gillette products.

So far, so good. Gillette discovered it could improve its customer service without having to invest in new infrastructure. However, as Knabe discovered, carrying all products in both warehouses would have significantly increased inventory levels, which was a no-no. To get past this potential sticking point, the company conducted a statistical safety stock analysis to optimize its distribution network. Gillette made some process changes to set its safety stock targets, which made it possible to hold inventory constant while improving customer service.

"Your distribution network should be a function of what your business strategy is," Knabe emphasizes. "If your business strategy is to be the low-cost provider, you set up one kind of a network. Wal-Mart, for example, sets up its distribution network to be as cost efficient as possible. If your business strategy is to be as responsive as possible, you set up a different network. For Boston Scientific, a maker of surgical equipment, it's not about the cost of its distribution network, it's about having the right product at the right place instantly."

In the end, by adhering to best practices in configuring its distribution network, Gillette was able to maximize its use of truckload shipments while improving its on-time deliveries to its customers. As a result, its goal of "excellent customer service at least cost" became a reality.

HOW MUCH IS TOO MUCH?

So how do you know if you're spending too much on your distribution network? Using the Site Selector index of the most logistics-friendly cities, location consulting firm The Boyd Company developed a comparative cost model that identifies how much it costs, on average, to operate a warehouse in the top 50 markets.10

Boyd's comparative model focuses on a hypothetical 350,000-square-foot warehouse employing 150 nonexempt workers. This hypothetical warehouse serves a national distribution network that delivers products to 10 destination cities. Not surprisingly, New York City is the most expensive city in which to own a warehouse, in terms of annual operating costs, which Boyd estimates to be $15.8 million. Of the cities studied, the least expensive is Mobile, Alabama, at $10.4 million.

The most expensive city in which to lease a warehouse is San Francisco ($14.5 million), while Mobile again ranks as the least expensive ($9 million). Overall trends play out pretty much as you'd expect: Cities in the Southeast tend to be the least expensive, those in the Northeast and on the West Coast are the most expensive, and the Midwest places in the middle.

Boyd also looks at a hypothetical outbound shipment model that assumes a volume of freight in 30,000-pound truckload shipments costing $1.46 per mile to move. This model indicates that it costs the most to serve a national market from Portland, Oregon ($4.1 million), while the most economical city for outbound shipments is St. Louis, Missouri ($2.4 million).

According to Jack Boyd, principal of The Boyd Company, companies now prefer to build their own warehouses rather than lease them. The trend today is also toward building fewer but larger facilities, often including nonwarehousing corporate functions within the buildings to save on costs. In effect, this involves moving white-collar workers into blue-collar locations. You're locating to a warehouse where real estate costs $5 per square foot versus the $20 or more per square foot you would pay in an office building, Boyd points out. "Staffing requirements for warehouses have been elevated over the years as companies become more information technology intensive," Boyd explains. "There are greater labor and skill set demands, and it does require more labor cost analysis as part of the mix in terms of where these warehouses should be located."
