So the quickest a part can have an upgraded design completed is 2 days. Say I have enough designers to get 1 part able to be designed in 2 days, but not enough to get a second part done in 2 days. If I assign all my remaining designers to the second part, it will be finished in 5 days (as an example).
Is there any advantage to putting the remaining designers onto that 5 day project? When my other designers free up in 2 days and I assign them to the partially completed part, it still seems like the quickest they'll complete the part is 2 more days.
