In our case, we have this situation with SW vs HW shipping culture. On the SW side, we focus on continuously developing features and have deliberately emphasized productivity over schedule-predictability, while on the HW side they naturally are focused more on schedule-predictability due to complex dependencies.
Now, this dichotomy has created an interesting discussions inside the company on the right way to ship products and projects, and to me, arguments mainly come from the fact that people come from the different shipping culture and have hard time to see the benefits and requirements of the other culture.
