Answer:
Science-push
Step-by-step explanation:
The science push approach was the first linear model (1950s - 1960s) developed in order to explain the innovation process. It is called a linear model since it believed that innovation started with scientific discovery, then invention, engineering, manufacturing and finally the marketing of a new product.
Science-push approach
basic science ⇒ research an development ⇒ production ⇒ marketing
The basic error of this model is that it doesn't consider any type of feedback at any stage.
