Benefits of Defender Strategy
Hi Cassandra, to the best of my knowledge, a prospector is a firm which endeavors to innovate. Therefore, it is quite similar with differentiation strategist of Porter. However, a defender tries to decrease the costs of its products. Hence, it resembles Porter's cost leaders
But the main difference between Porter and Miles-Snow strategy typologies is that the first one emphasizes competition. On the other hand, the second one stresses that all kind of strategists need each other to survive.
For example, as a prospector, you need a defender which will decrease the costs of your innovation and enable your products to reach large customer base.
