On-time delivery is a fundamental premise behind supply chain management, and it's a key benchmark on the road to achieving the perfect order. Although same-day delivery is available from several logistics providers, any company relying on the fastest and most expensive transportation options to fulfill its delivery obligations isn't going to be in business very long. The old adage, "Build a better mousetrap and the world will beat a path to your door," is now hopelessly out of date. It's no longer good enough to build that better mousetrap—you also have to build a better distribution network from which you can optimally service your customers. According to a study undertaken by consulting firm ProLogis Global Solutions, the number-one challenge for supply chain professionals is to create a distribution network that can deliver on customer demands while still keeping costs in line.

High-tech manufacturer Hewlett-Packard Co. operates one of the largest supply chains in the world, as well as one of the most sophisticated distribution networks. Its 88 distribution hubs serve more than 1 billion customers worldwide, in 178 countries. HP's supply chain also includes 32 manufacturing plants, 700 suppliers, and 119 logistics partners, and all told in 2005 the supply chain group managed $51 billion—or 64 percent—of the company's total spend.

The company credits much of its success to its adaptive supply chain—a product-agnostic supply chain portfolio that allows multiple supply chains. After direct materials, logistics is the company's main cost driver, according to Robert Gifford, HP's vice president of worldwide logistics and program management. It is "an absolute necessity to consider logistics activity" when deciding where to source products and where to build factories, he emphasizes.

"We don't just say, 'We're going to put up a factory here,' and then figure out how we'll move product," Gifford notes. Instead, HP relies on collaboration across its entire supply chain to design the optimum distribution network to bring a given product to a specific marketplace.

Where once upon a time HP, like other high-tech companies, relied on design for manufacturability strategies to build products as efficiently and inexpensively as possible, the company recently has adopted a best practice known as design for supply chain. This relatively new concept looks at all of the costs throughout a product's life cycle, even past the point of its functional use. By its very nature, design for supply chain requires the involvement of multiple departments when a product is being designed.

"Design for supply chain includes not only research and development type people but also people involved with logistics and packaging, and people who are focused on the environment," explains Greg Shoemaker, HP's vice president of central direct procurement. "When we design for logistics enhancements, for instance, we make sure we've got the right size box that'll lit on the right size pallet to optimize our shipping costs. When we design for tax and duty reduction, we may manufacture in certain places in the world in order to reduce our taxes or duty."-

The applications of design for supply chain are seemingly limited only by a company's imagination, as well as its ability to effectively pull together disparate functions. Design for postponement, which is also popular with the apparel industry, allows a company to wait until the last minute to finish making a product, pushing off configuration or a value-added feature until the product is as close as possible to the end customer. HP also engages in design for commonality and reuse, which involves using similar or identical components in different products. HP's designs for take-back and recycling efforts are supplemented by its own recycling operation plant, which has recycled more than 4 million pounds of computer hardware.

"What we're really working on and making a lot of progress in is making sure that the development teams get a good view and understanding of all the supply chain variables that can be affected by their design, depending on what the particular sourcing strategy is," Shoemaker explains. "So we try to identify all those needs up front, even where the product is going to be manufactured, so that the designers can spend a good amount of quality time creating the best package."

STRIKING THE PROPER BALANCE

A well-run supply chain depends on having a streamlined distribution network to receive raw materials and deliver product to the end user, and that network needs to use the least number of intermediate steps possible. Developing such a network where total system-wide costs are minimized while system-wide service levels are maintained involves studying and weighing numerous factors. The ultimate goal of this network planning is a supply chain that is properly balanced between the competing considerations of inventory, transportation, and manufacturing.

"The objective of strategic distribution network planning," according to Dale Harmelink, a partner with supply chain consulting firm Tompkins Associates, "is to come up with the most economical way to ship and receive products while maintaining or increasing customer satisfaction requirements; simply put, a plan to maximize profits and optimize service."

Distribution network planning determines how many warehouses or distribution centers a company requires to satisfy its customer base, as well as where those warehouses should be located.

A distribution network plan, Harmelink suggests, should answer the following questions:

How many distribution centers (DCs) do you need?
Where should the DCs be located?
How much inventory should be stocked at each DC?
Which customers should be serviced by each DC?
How should customers order from the DC?
How should the DCs order from suppliers?
How often should shipments be made to each customer?
What should the service levels be?
Which transportation methods should be used?

Depending on the market needs of a company and its overall supply chain mission, the answer to question 1 may necessitate adding one or more DCs to the network, or conversely, it may require consolidating several DCs into a single regional distribution hub.
