As a math and stats nerd, I have played around a lot with numbers related to this game, but this isn't one of areas I looked into.
Normally, you can just use the "look ahead" feature in each enterprise to see when you lose efficiency by hiring more people. This usually requires waiting for repeated usage, as there is a lag in the game for updates. However, I think this is fixed in the newer look/version (not sure???)!!
Even if you lose efficiency, you get a benefit of having more customers/profit (for stores/ front-facing enterprises), and faster increase in qualification in most cases, so its not worth it to get too lost in this, trust me!
For factories, tech is probably a bigger concern. You can generally make more with better quality products, than with more of them. |
