Preserving efficiency in some of your factories could lead to a more diverse and interesting combination of units, and allow you to discover some parts of the game you might have ignored if you just constantly upgraded. Swiftly find equipment tags to use with console commands such as addequipment in Hearts of Iron IV. Should you go for a large number of weapons you can already churn out, or take a short term hit on production in favor of making a smaller number of higher quality ones? Sure, your new T-43 tank is better than the T-34, but is it really enough of an improvement to lose much of your Production Line's Efficiency when you switch over? Your PzIII tank may be obsolete, but perhaps instead of canceling their production entirely you could convert the Line to make Tank Destroyers or Self-Propelled Artillery on the PzIII chassis.

Our larger hope is that Production Lines and efficiency will offer players some interesting choices when it comes to deciding what to build. you switch from Pz IIIs to StuG IIIs) you keep half your Efficiency. If you switch to another variant of the same chassis (e.g. If you change to a modified version of the same equipment (for example, the same tank but with a larger gun) you keep most of your Efficiency. You can change what a Production line produces, of course, and this normally means all your Efficiency is lost, however there are some exceptions.
