The supply chain perspective on technology suggests that:

a. network externalities are more likely to exist at the retail level than at the end-user level.
b. creative destruction is more likely to apply among categories of adopters at the end-use level than elsewhere in the supply chain.
c. supply and demand ultimately determine prices, just as in more conventional markets.
d. incremental innovations are more likely to occur at the supplier level of the supply chain, while more radical innovations are likely to occur at the end-user level.
e. although actual end-user behavior may not have changed significantly, major innovations at higher levels in the supply chain (i.e., at the level of suppliers) can be characterized as revolutionary.
