how each value network exhibits a very different rank-ordering of important product attributes, even
for the same product. In the top-most value network, disk drive performance is measured in terms of
capacity, speed, and reliability, whereas in the portable computing value network, the important
performance attributes are ruggedness, low power consumption, and small size. Consequently, parallel
value networks, each built around a different definition of what makes a product valuable, may exist
within the same broadly defined industry.

Although many components in different systems-of-use may carry the same labels (for example, each
network in Figure 2.2 involves read-write heads, disk drives, RAM circuits, printers, software, and so
on), the nature of components used may be quite different. Generally, a set of competing firms, each
