10.1.1 Matching the supply chain to the product

The relationship between a product and its supply chain is fundamental and has tremendous implications on the value stream generated by the firm's business processes. Given that the physical attributes of the product change during its passage through the supply chain, we can concentrate on the final end product which the consumer is willing to accept. Thus we are looking at the value associated with the end product. The rational aim is to look for ways to improve all processes, procurement, manufacturing, logistics and distribution to satisfy the customer's demand at minimum cost and, perhaps, with maximum profit. One important element that can assist in achieving this goal is the alignment of product design with supply chain strategies.

We know, of course, that every supply chain is unique and that the supply chain network and strategies may differ, not only from industry to industry, but also between different firms within the same industry. Although this observation is important and valid, there are some general traits which relate the nature of the supply chain with the product in a broad way. The classic encapsulation of this relationship has been provided by Fisher who has classified products in two broad categories, functional and innovative . This classification is based on the nature of the demand for the product. In short, functional products have a reasonably long life cycle, fairly predictable demand, low profit margin, low obsolescence rate and a fairly long lead time. Innovating products are exactly opposite with a short life cycle, high profit margin, high rate and cost of obsolescence and a fairly short lead time.

Examples of innovative products are seasonal fashion products, cellular telephones and personal computers. Functional products include items such as refrigerators, boats and ships and vehicles.

The supply chains are similarly classified into physically efficient supply chains and responsive supply chains. As the names imply, physically efficient supply chains focus on cost minimisation by streamlining inventory, manufacturing and distribution. The responsive supply chain on the other hand focuses on quick response to changing market demand. The attributes are short lead time and excess buffer inventory in the system to respond quickly to changing market conditions. Fisher (1997) provides the following matrix for effective supply chain strategies on the basis of these classifications.

This simple matrix of matching products with the supply chain is a classic explanation of the underlying relationship between a product and its supply chain. It is this quest for value by designing a supply chain to match the product that drives businesses towards innovative product design solutions. This is the back ground to the concept of design for logistics.
