Answer: Firms differentiate by establishing linkages within or between firms. Examples are linkages among functions within a firm, linkages with other firms, product mix, distribution channels and service and support
Explanation:
The whole premise of Differentiation is that Firms make a different product from their competitors to maintain a Comparative Advantage.
Should Firms now start to collaborate with other firms by making linkages with them, their product mixes and distribution, the firms will have similar products that are NOT as differentiated if differentiated at all.
This option is therefore NOT a factor of Differentiation.
