Managers have been wanting to treat developers as assembly line workers since forever. It harkens back to the promise of object oriented programming — that if the interfaces were well defined upfront then development would be reduced to just implementing the code while conforming to the interface. Of course, that never worked because software development is a fundamentally creative and iterative process, so the assembly line model is doomed to fail every time.
