Sometimes it seems like throwing four people at a project makes the project span 4 months, when a single person could have completed the work in a couple of weeks. Your communication lines are O(n^2) (actually, (n^2-n)/2)… 2 -> 1, 3 -> 3, 4 -> 6. If you’re not doing mostly independent pieces, you’re creating an unofficial management position for every 2-3 people you sign up. Realistically, 6 would be 15 units and 12 would be 66 units, so a mere doubling in time is really optimistic unless the 6 extra workers are making sure that project managers and customers don’t bug the workers actually building the car.
Worse still, usually, the extra 6 workers will need to be brought up to speed mid-project by the other 6 workers on top of introducing the extra ongoing communication complexity.
In other words, (ノಠ益ಠ)ノ彡┻━┻
