That's exactly right. As an example, for an idealized discussion on internal combustion engines, they may assume Carnot efficiency. But all parties involved with the discussion know full well actual efficiency will be nowhere close (example, 40% [idealized] vs 23% [non- idealized, real world]). Making this assumption simplifies math and removes variables. Thereby shortening the discussion, focusing on the specific issue at hand.
